Abstract
Background and Aims Human papillomavirus (HPV) infections that continue to exist are the main cause of cervical cancer (CC), two-thirds of CC occurrences worldwide are caused by HPV 16 and HPV 18, and 99.7% of CC tumors are linked to oncogenic HPV infection. To identify challenges of CC and its prevention and treatment modalities. Methods This review examined the epidemiology, predisposing factors, genetic factors, clinical assessment methods, current treatment options, and prevention approaches for CC. We had perform a narrative data synthesis rather than a pooled analysis. A thorough literature search in pertinent databases related to CC was done with the inclusion of data that were published in the English language. Results Early detection of CC is of utmost importance to detect precancerous lesions at an early stage. Therefore, all responsible agencies concerned with health should make all women aware of the benefits of CC screening and educate the general public. HPV vaccination coverage is very low in resource-limited settings. Conclusion To achieve the goal of eliminating CC as a public health problem in 2030, the World Health Organization will pay special attention to increasing HPV vaccination coverage throughout the world. To further improve HPV vaccine acceptability among parents and their children, safety-related aspects of the HPV vaccine should be further investigated through post-marketing surveillance and multicentre randomized clinical trials.

[PMID: 37410084 PMCID: PMC10472094 DOI: 10.1158/1055-9965.epi-23-0300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 06/04/2023] [Accepted: 06/30/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND Cervical cancer oncogenesis starts with human papillomavirus (HPV) cell entry after binding to host cell surface receptors; however, the mechanism is not fully known. We examined polymorphisms in receptor genes hypothesized to be necessary for HPV cell entry and assessed their associations with clinical progression to precancer. METHODS African American women (N = 1,728) from the MACS/WIHS Combined Cohort Study were included. Two case-control study designs were used-cases with histology-based precancer (CIN3+) and controls without; and cases with cytology-based precancer [high-grade squamous intraepithelial lesions (HSIL)] and controls without. SNPs in candidate genes (SDC1, SDC2, SDC3, SDC4, GPC1, GPC2, GPC3, GPC4, GPC5, GPC6, and ITGA6) were genotyped using an Illumina Omni2.5-quad beadchip. Logistic regression was used to assess the associations in all participants and by HPV genotypes, after adjusting for age, human immunodeficiency virus serostatus, CD4 T cells, and three principal components for ancestry. RESULTS Minor alleles in SNPs rs77122854 (SDC3), rs73971695, rs79336862 (ITGA6), rs57528020, rs201337456, rs11987725 (SDC2), rs115880588, rs115738853, and rs9301825 (GPC5) were associated with increased odds of both CIN3+ and HSIL, whereas, rs35927186 (GPC5) was found to decrease the odds for both outcomes (P value ≤ 0.01). Among those infected with Alpha-9 HPV types, rs722377 (SDC3), rs16860468, rs2356798 (ITGA6), rs11987725 (SDC2), and rs3848051 (GPC5) were associated with increased odds of both precancer outcomes. CONCLUSIONS Polymorphisms in genes that encode binding receptors for HPV cell entry may play a role in cervical precancer progression. IMPACT Our findings are hypothesis generating and support further exploration of mechanisms of HPV entry genes that may help prevent progression to cervical precancer.

Abstract
Despite being one of the commonest malignancies among women worldwide, carcinoma of the cervix, due to its nonspecific symptoms, goes undiagnosed until it reaches advanced stages. This is especially true among women living with human immunodeficiency virus (HIV) as the rate of screening for them is much less as compared to noninfected women. HIV infection greatly impacts the treatment and the prognosis of the diagnosed carcinoma. The existing common linkage between the occurrence of HIV and that of cervical cancer has some significant common elements such as low socio-economic conditions and poor hygiene. The treatment methods in such cases, prove to be of concern, taking into consideration the seropositive status of the case. Here, we discuss one such case of a seropositive patient who presented with complaints of leukorrhea, dysmenorrhea, and dyspareunia. She had stable vitals, with a pulse rate of 86/minute and blood pressure of 100/80 mmHg. On clinical examination, she was diagnosed with stage International Federation of Gynecology and Obstetrics (FIGO) IIIB cervical carcinoma. Under all aseptic precautions, a cervical biopsy was taken and moderately differentiated squamous cell carcinoma of the cervix was diagnosed. A multidisciplinary approach was decided as the course of action, after which she was referred to the department of medical oncology for chemoradiation. Five cycles with a dose of ten Gray (GY) per cycle were planned with concurrent chemotherapy with cisplatin per week. The patient was advised to follow up in the gynecology outpatient department after completion of her chemoradiation cycles for further evaluation and management.

Abstract
OBJECTIVE Similar to Human Papillomavirus (HPV) genotypes, different lineages of a genotype also have different carcinogenic capabilities. Studies have shown that specific genotype lineages of oncogenic HPV are associated with variable risks for the development of cervical intraepithelial neoplasia (CIN2/CIN3) and cervical cancer. The present study aimed to analyze the genetic diversity of the HPV16 genotype in women with CIN2/CIN3 and cervical cancer, from the northeast region of Brazil. METHODS A cross-sectional multicenter study was conducted in the northeast region of Brazil, from 2014 to 2016. This study included 196 cases of HPV16 variants (59 and 137 cases of CIN2/CIN3 and cervical cancer, respectively). The difference of proportion test was used to compare patients with CIN2/CIN3 and cervical cancer, based on the prevalent HPV16 lineage (p < 0.05). RESULTS According to the histopathological diagnosis, the percentage of lineage frequencies revealed a marginal difference in the prevalence of lineage A in CIN2/CIN3, compared with that in cervical cancer (p = 0.053). For lineage D, the proportion was higher in cancer cases (32.8%), than in CIN2/CIN3 cases (16.9%), with p = 0.023. CONCLUSION HPV16 lineage A was the most frequent lineage in both CIN2/CIN3 and cervical cancer samples, while lineage D was predominant in cervical cancer, suggesting a possible association between HPV16 lineage D and cervical cancer.

[PMID: 32881598 DOI: 10.1080/13813455.2020.1804406] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2020] [Accepted: 07/27/2020] [Indexed: 02/07/2023]
Abstract
LncRNA LOXL1-AS1 has been reported to be upregulated in several types of cancer and plays oncogenic roles. We analysed TCGA dataset and observed the downregulation of LOXL1-AS1 in cervical squamous cell carcinoma (CSCC). We therefore analysed the roles of LOXL1-AS1 in CSCC. We observed that LOXL1-AS1 was downregulated in CSCC. LOXL1-AS1 was predicted to interact with miR-21, while overexpression experiments showed that LOXL1-AS1 and miR-21 had no significant effects on the expression of each other. However, LOXL1-AS1 overexpression led to the upregulation of RHOB, a direct target of miR-21. Cell invasion and migration analysis showed decreased invasion and migration rates of CSCC cells after LOXL1-AS1 and RHOB overexpression. MiR-21 played an opposite role at reduced the effects of LOXL1-AS1 and RHOB overexpression. Therefore, LOXL1-AS1 may promote CSCC cell invasion and migration by sponging miR-21 to upregulate RHOB.

Abstract
IntroductionAfter the diagnosis of L-SIL, 77. 3% had a persistent infection and anomalous Pap Test results. Many of these patients had highlighted psychological consequences such as anxiety, hypochondria, fear of cancer, and sexual problems. Several studies suggested that the clearance of HR-HPV infection could be accelerated by cervical excisional procedures, especially in L-SIL. In consideration of the psychological implications for HPV infection and related dysplasia in patients with CIN1 at PAP-smear and HR-HPV positivity at least for 6 months, we decided to plan a prospective study where we tried to anticipate excisional cervical using a minimally invasive treatment: thin loop electrosurgical excision procedure (t-LEEP). This study aims to analyze the clearance of HR-HPV after 6 and 12 months, clinical outcomes related to t-LEEP, and the psycho-relational impact at 12 months after t-LEEP.Materials and MethodsWe enrolled patients with the diagnosis of L-SIL at PAP-smear and HR-HPV positivity with a persistent CIN 1 (at least for 6 months), confirmed by cervical biopsy. All enrolled patients underwent t-LEEP. We followed prospectively and performed for all patients the HPV DNA test at 6 (T1) and 12 months (T2) and STAI-Y and FSFI scores at T0 and T2.ResultsWe prospectively enrolled 158 patients, 22 are excluded for the established criteria. Patients with HR-HPV and CIN 1 lesions treated with t-LEEP had an overall clearance of 83.8% at T2. In subgroups analysis at T2, we had a regression: in smoker 71.8%, in contraceptive users 69.5%, in patients aged <25 years 100%, aged 25–30 years 85%, aged 30–35 years 94.4%, aged 35–40 years 92%, and aged ≥40 years 89.1%, in HPV-16 96.4%, in HPV-53 89.5%, in HPV-18 87.5%, in HPV-31 86.6%, and in coinfected 3.5%. STAI-Y and FSFI after t-LEEP (T2) were statistically significant, reducing anxiety status and improving sexual function.ConclusionBased on these results, the use of t-LEEP in patients with persistent CIN 1 and HPV-HR at least for 6 months could be useful for accelerating HPV-HR clearance, in particular, for a subpopulation patient with an increased risk of progression and/or patients with psychological and sexual consequences of carrying an HR-HPV infection.

Abstract
Background The tumour necrosis factor-α (TNF-α) gene plays an important role in the host immune response, which will influence the development and clearance of cancer. Polymorphism of the TNF-α promoter region is considered to influence its transcription and be a risk factor for tumorigenesis. In the current study, we evaluated the role of TNF-α promoter region polymorphisms in susceptibility to cervical intraepithelial neoplasia (CIN) and cervical cancer (CC). Methods A total of 2732 subjects, including 1173 healthy controls, 579 patients with CIN and 980 patients with CC in a Chinese Han population, were selected for the current study. Five SNPs in the TNF-α promoter, rs1799964 (−1031 C>T), rs1800630 (−863 A>C), rs1799724 (−857 C>T), rs1800629 (−308 A>G) and rs361525 (−238 A>G), were selected and genotyped using TaqMan Assays. The association of these SNPs with CIN and cervical cancer was evaluated among healthy controls, CIN and CC patients. Results The frequency distribution of rs1800629 and rs361525 alleles was significantly different between the CC group and the control group (P=0.009 and P=0.002). The rs1800629 A allele was found to be a protective factor for CC (OR=0.72; 95% CI=0.56–0.92). The rs361525 A allele was found to be a risk factor for CC (OR=1.69; 95% CI=1.21–2.38). After pathological subtyping of CC, the allele distribution of rs1800629 and rs361525 were both significantly different between the cervical squamous cell carcinoma and control groups (P=0.002 and P<0.001). The rs1800629 A allele was protective factor for cervical squamous cell carcinoma (OR=0.66; 95% CI=0.50–0.86). The rs361525 A allele was a risk factor for cervical squamous cell carcinoma (OR=1.87; 95% CI=1.32–2.65). Moreover, the genotypic frequency of rs361525 was significantly different between cervical cancer stage I and stage II (P=0.003). Conclusion The rs1800629 and rs361525 in the TNF-α promoter are associated with susceptibility to CC in the Chinese Han population.

Abstract
Differential expression of p53 has been reported in cervical cancer, primarily in tumor tissue biopsies. In this study, we examined the association of TP53 codon 47 and codon 72 polymorphisms and serum level expression of p53 in cervical cancer patients (n = 129) and healthy controls (n = 122). We found elevated levels of serum p53 protein levels in cervical cancer patients (p = 0.0442) compared to healthy controls. Moreover, we found higher levels of serum p53 in patients with grade-III tumor (p = 0.001) compared to healthy controls. Examination of SNPs showed TP53 Arg/Pro heterozygosity (adjusted OR = 2.126, 95% CI = 1.181-3.827, p = 0.012), Pro/Pro mutant homozygosity (adjusted OR = 3.564, 95% CI = 1.647-7.713, p = 0.001), along with the combined genotype (Arg/Pro+Pro/Pro) (adjusted OR 2.542, 95% CI = 1.517-4.260, p<0.001) significantly increases the risk of cervical cancer. Expression quantitative trait analysis revealed no significant association with protein expression. Our results represent for the first time the upregulation of serum p53 in cervical cancer in Bangladeshi women and supports the association of TP53 codon 72 polymorphisms with cervical cancer.

Abstract
Human papillomavirus (HPV) is a well-known sexually transmitted disorder globally. Human papillomavirus (HPV) is the 3rd most common cancer that causes cervical carcinoma, and globally it accounts for 275,000 deaths every year. The load of HPV-associated abrasions can be lessened through vaccination. At present, three forms of prophylactic vaccines, Cervarix, Gadrasil, and Gardasil 9, are commercially accessible but all these prophylactic vaccines have not the ability to manage and control developed abrasions or infections. Therefore, a considerable amount of the population is not secured from HPV infectivity. Consequently, the development of therapeutic HPV vaccines is a crucial requirement of this era, for the treatment of persisting infections, and to stop the progression of HPV-associated cancers. Therapeutic vaccines are a developing trial approach. Because of the constitutive expression of E6 and E7 early genes in cancerous and pre-cancerous tissues, and their involvement in disturbance of the cell cycle, these are best targets for this therapeutic vaccine treatment. For the synthesis and development of therapeutic vaccines, various approaches have been examined comprising cell-based vaccines, peptide/protein-based vaccines, nucleic acid-based vaccines, and live-vector vaccines all proceeding towards clinical trials. This review emphasizes the development, progress, current status, and future perspective of several vaccines for the cure of HPV-related abrasions and cancers. This review also provides an insight to assess the effectiveness, safety, efficacy, and immunogenicity of therapeutic vaccines in the cure of patients infected with HPV-associated cervical cancer.

Drokow EK, Effah CY, Agboyibor C, Sasu E, Amponsem-Boateng C, Akpabla GS, Ahmed HAW, Sun K. The Impact of Video-Based Educational Interventions on Cervical Cancer, Pap Smear and HPV Vaccines. Front Public Health 2021; 9:681319. [PMID: 34307280 PMCID: PMC8294697 DOI: 10.3389/fpubh.2021.681319] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 06/08/2021] [Indexed: 01/24/2023] Open
Abstract
Background: Video-based interventions have the potential to contribute to long-lasting improvements in health-seeking behaviours. Ghana's upsurge rate of information and communication technology usage presents an opportunity to improve the awareness of HPV vaccination and screening rates of cervical cancer among women in Ghana. This research aimed to assess the impact of video-based educational intervention centred on the Health Belief and Transtheoretical Models of behavioural changes in promoting HPV vaccination, cervical carcinoma awareness and willingness to have Pap smear test (PST) among women in Ghana. Methods: To achieve the intended sample size, convenient, purposive and stratified random sampling techniques were used. SPSS v. 23.0 was used in the data analysis. Percentages and frequencies were used to represent participants' demographic characteristics, knowledge of (1) cervical carcinoma, (2) human papillomavirus vaccine, and (3) Pap smear test. The chi-square test by McNemar was employed to evaluate variations in the post- and pre-intervention responses. A p-value < 0.05 was considered statistically significant. The level of significance was adjusted owing to multiple comparisons by using the Bonferroni's correction. Results: Before the intervention, 84.2% of the participant had some knowledge or information about cervical cancer, but after the intervention, 100% of the participant became aware of cervical cancer which represents 15.8% increment at a P < .001. The willingness to have a pap smear test increased from 35.8% to 94.2% (df = 58.4%, P < .001) after the educational intervention. The willingness to be vaccinated increased from 47.5% to 81.7% (df = 34.2%, P < .001) after the educational intervention. Six months after the intervention, participants were followed-up. 253 (42.2%) participants had gone for cervical cancer screening (Pap smear test) while 347 (57.8%) participants had not been screened. In terms of HPV vaccination, 192 participants (32.0%) had begun their HPV vaccination cycle. Conclusion: The study results show that health education, using videos, may be influential in perception changing, self-efficacy improvement and the understanding of cervical carcinoma screening and HPV vaccination.

Abstract
BACKGROUND The pathogenesis of penile intraepithelial neoplasia (PeIN) is unclear but human papillomavirus (HPV) infection and polymorphisms in human leucocyte antigen (HLA). OBJECTIVES To examine the prevalence of HPV DNA and HLA in PeIN. METHODS Adult Caucasian men with a clinical and histological diagnosis of PeIN, that is, Bowenoid papulosis (BP), Bowen's disease of penis (BDP) and erythroplasia of Queyrat (EQ) were selected and phenotyped from the clinical records. DNA was extracted from blood and paraffin-embedded sections for HLA and HPV typing, respectively. Human leucocyte antigen allele frequencies were compared with those derived from the UK-based Caucasian population. RESULTS Seventy-two cases of PeIN (20 BP, 34 BDP and 18 EQ) were studied. Human papillomavirus DNA was identified in 65/72 (90.2%) PeIN; Alphapapillomavirus types were detected in 62/72 (85%) followed by Betapapillomavirus types in 9/72 (12.5%) and cutaneous types in 7/72 (9.7%); HPV16 was the most prevalent genotype at 35/72 (48.6%) followed by HPV33 at 7/72 (9.7%); multiple infections were seen in 18/72 (25%) PeIN. HLA-C*15 (Bonferroni corrected p = 0.049) confers susceptibility to PeIN, whereas HLA-DQA1*01 (corrected p = 0.02) protects against PeIN. HPV16-associated PeIN cases showed no statistically significant association with HLA genotype after multiple corrections. CONCLUSION Human papillomavirus is involved in the pathogenesis of PeIN. Immunogenotype may play a role in the pathogenesis of PeIN.

Abstract
South African women have a high rate of cervical cancer cases, but there are limited data on human papillomavirus (HPV) genotypes in cervical intraepithelial neoplasia (CIN) in the Eastern Cape province, South Africa. A total of 193 cervical specimens with confirmed CIN from women aged 18 years or older, recruited from a referral hospital, were tested for HPV infection. The cervical specimens, smeared onto FTA cards, were screened for 36 HPV types using an HPV direct flow kit. HPV prevalence was 93.5% (43/46) in CIN2 and 96.6% (142/147) in CIN3. HIV-positive women had a significantly higher HPV prevalence than HIV-negative women (98.0% vs. 89.1%, p = 0.012). The prevalence of multiple types was significantly higher in HIV-positive than HIV-negative women (p = 0.034). The frequently detected genotypes were HPV35 (23.9%), HPV58 (23.9%), HPV45 (19.6%), and HPV16 (17.3%) in CIN2 cases, while in CIN3, HPV35 (22.5%), HPV16 (21.8%), HPV33 (15.6%), and HPV58 (14.3%) were the most common identified HPV types, independent of HIV status. The prevalence of HPV types targeted by the nonavalent HPV vaccine was 60.9% and 68.7% among women with CIN2 and CIN3, respectively, indicating that vaccination would have an impact both in HIV-negative and HIV-positive South African women, although it will not provide full protection in preventing HPV infection and cervical cancer lesions.

Abstract
Background Previous work has shown that miR-142-5p in cervical cancer tissues increased significantly compared with adjacent normal tissues. However, the function and the mechanism of miR-142-5p in cervical cancer have not been reported. Methods Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to determine the gene expression levels. MTT, flow cytometry, and transwell assays were performed to explore the functions of miR-142-5p in HeLa cells. The potential target gene of miR-142-5p was investigated via luciferase reporter assays. The protein expression levels were analyzed by Western blotting. Results We found that miR-142-5p expression was elevated but LIM homeobox transcription factor 1 alpha (LMX1A) was decreased in cervical cancer tissues and cells. Overexpression of miR-142-5p or knockdown of LMX1A inhibited cell apoptosis, promoted cell proliferation, migration, invasion abilities, and activated the Wnt/β-catenin pathway. However, knockdown of miR-142-5p or overexpression of LMX1A showed opposite results. LMX1A was identified as a direct target of miR-142-5p by luciferase reporter assays. Finally, rescue experiments demonstrated that LMX1A overexpression attenuated the carcinogenic effect of miR-142-5p mimic on HeLa cells. Conclusions These findings suggested that miR-142-5p might be a cervical cancer oncogene and could serve as a potential therapeutic target for the treatment of cervical cancer.

Abstract
Cervical cancer (CC) is the second most common cancer and the leading cause of cancer mortality in women. Numerous studies have found that the development of CC was associated with multiple genes. However, the mechanisms on gene level are enigmatic, hindering the understanding of its functional roles. This study sought to identify prognostic biomarkers of CC, and explore their biological functions. Here we conducted an integrated analysis to screen potential vital genes. Candidate genes were further tested by experiments in clinical specimens and cancer cell line. Then, molecular modeling was used to predict the three-dimensional structure of candidate genes’ proteins, and the interaction pattern was analyzed by docking simulation technique. Among the potential genes identified, we found that TAF1A and ZBTB41 were highly correlated. Furthermore, there was a definite interaction between the proteins of TAF1A and ZBTB41, which was affected by the activity of the p53 signaling pathway. In conclusion, our findings identified TAF1A and ZBTB41 could serve as biomarkers of CC. We confirmed their biological function and deciphered their interaction for the first time, which may be helpful for developing further researches.

Different Genotype Distribution of Human Papillomavirus between Cervical and Esophageal Cancers: A Study in Both High-Incidence Areas, Xinjiang, China. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7926754. [PMID: 33354570 PMCID: PMC7735827 DOI: 10.1155/2020/7926754] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 11/07/2020] [Accepted: 11/27/2020] [Indexed: 12/26/2022]
Abstract
The aim of this study is to reveal the certain human papillomavirus (HPV) genotype distribution between cervical cancer and esophageal cancer in the both high-incidence geographic regions. For this study, we collected and detected the infection of HPV in 120 paraffin-embedded esophageal tissues and 152 paraffin-embedded cervical tissues, respectively. The esophageal tissues include 40 normal epithelium (ENOR), 26 dysplasia (DYS), and 54 invasive squamous cell carcinoma (ESCC). The cervical tissues consisted of 40 normal epithelium (CNOR), 53 intraepithelial neoplasia (CIN), and 59 invasive squamous cell carcinoma (CSCC). Both esophageal and cervical tissues collected in this study came from the same area, in which both the ESCC and CSCC were in high incidence, Xinjiang province, China. HPV GenoArray test kits were served to analyze the HPV infection. The result shows that among the 59 CSCC tissues, the total infection rate of HPV was 98.3% (58/59). The positive rate of HPV-16 infection was 63.8% (37/58). It indicated that HPV-16 is the most common infection among all of the high-risk HPV. The multiple infection rate was 19.0% (11/58). Among the 54 ESCC, a total of 7 genotypes were detected. The total infection rate of HPV was 61.1% (33/54). The positive rate of HPV-16 infection was 63.6% (21/33). The multiple infection rate was 6.1% (2/33). Our result shows that high-risk-type HPV-16 was associated with both cervical cancer and esophageal cancer, which play a role in the high-incidence area in Xinjiang. We hope that our results could point out the direction for the treatment strategy of HPV-associated cancer, cervical cancer, and esophageal cancer and for the application of HPV vaccines in the future.

Abstract
Despite the wide application of iron oxide nanoparticles (IONPs), little is known about the specific mechanism of their nephrotoxic effect. We aimed to evaluate the nephrotoxic effects of iron oxide nanoparticles (IONPs) in vivo and the protective effect of ellagic acid (EA) as a silent information regulator sirtuin 1 (SIRT1) activator against the induced nephrotoxicity. Forty male albino Wistar rats were randomly distributed into four equal groups (10 rats each): the control group (oral saline for 30 days), ellagic acid (EA) group (10 mg/kg b.w. EA, orally for 30 days), IONP group (20 mg/kg b.w. IONP I/P injection at the 24th-30th day), and EA + IONP group (10 mg/kg b.w./day EA for 30 days + 20 mg/kg b.w. IONPs at the 24th-30th day). In the present study, the potent antioxidant and antiapoptotic effects of EA were indicated by the significant overexpression of SIRT1 in renal tissues that leads to significant decreases in renal MDA content, P53 protein level and forkhead-box transcription factor1 (FOXO1) expression, and significant increases in renal GSH level, catalase activity, growth arrest and DNA damage-inducible protein 45 alpha (GADDα45), and renal inhibition of apoptosis protein (KIAP) gene expression levels in the EA + IONP-treated group. These results were confirmed by the improved histopathological renal features with EA administration. In conclusion, the present study provides the first evidence for the usefulness of EA as a sirtuin1 activator in the prevention or treatment of renal damage. Thus, EA could be used as a promising therapy for the prevention of IONP-induced nephrotoxicity.

Abstract
BackgroundThe pathogenesis of male genital lichen sclerosus (MGLSc) is controversial. Incriminated factors include infection with human papillomavirus (HPV) and autoimmunity (e.g. Human Leukocyte Antigen [HLA]). To address the roles of HLA and HPV in MGLSc we studied adult Caucasian males with a clinical and histological diagnosis of MGLSc. The men in the study attended two specialised Male Genital Dermatoses Clinics between July 2011 and September 2012 and were selected and phenotyped from the clinical records. DNA was extracted from blood and paraffin-embedded biopsy sections, for HLA and HPV typing, respectively. HLA allele frequencies were compared with those derived from the UK-based Caucasian population. Eighty-eight cases of MGLSc were identified. HPV DNA was detected in 33/88 (37.5%) cases of MGLSc. HPV16 was the most prevalent type found: 11/88 (12.5%) MGLSc. No statistically significant HLA associations were established but HLA-B*35, -B*51, -C*15, -DRB1*04, -DRB1*10 (predisposition) and -DQA1*01 (protection) were revealed as alleles of interest. HPV16-associated MGLSc cases showed no statistically significant association with HLA genotype. The relationship between HPV and MGLSc suggests a passenger effect rather than a pathogenic role. HLA is not associated with MGLSc nor co-existent HPV16.

Understanding HLA-G driven journey from HPV infection to cancer cervix: Adding missing pieces to the jigsaw puzzle. J Reprod Immunol 2020; 142:103205.

Abstract
Human Papillomavirus (HPV) is a vital risk-factor for cancer cervix. However, persistent HPV infection results in cervical cancer in only a minority. Probably, HPV subdues the host immune response for persistence, which includes augmentation of HLA-G and plausibly aids in progression to cervical cancer. HLA-G, which comprises of membrane and soluble form, downregulates the host's immune response and generate tolerance. The current study aimed to analyze both forms of HLA-G in fresh tissue and plasma of women with HPV-infected and uninfected cervix and cancer cervix using Western blot and ELISA. The study cohort included 30 women with cervical carcinoma and equal number with normal cervix and 6 with HPV infected cervix. We observed a significant upregulation of membranous HLA-G expression in HPV infected cervix and cervical carcinoma (P < 0.001). Interestingly, the pairwise comparison of HLA-G tissue protein expression of the normal cervix and cervical carcinoma, as well as the normal cervix with HPV infected cervix, was significant (P < 0.001). Levels of soluble HLA-G were significantly raised in carcinoma cervix. We observed a progressive increase in HLA-G protein expression in HPV infected cervix and cervical carcinoma. These findings compel us to hypothesize that the upregulation of HLA-G expression favors the persistence of HPV in a microenvironment of a submissive host response. This progressive upregulation further leads to cervical cancer. Thus elimination of HPV infection seems to be a desirable proposition to prevent cervical cancer. In the absence of antiviral therapy for HPV, exploration of HLA-G antibody-based therapeutic strategies appear promising.

Abstract
IMPORTANCE Understanding the genetic contribution of the major histocompatibility complex (MHC) region to the risk of cervical cancer (CC) will help understand how immune responses to infection with human papillomaviruses are associated with CC. OBJECTIVE To determine whether the HLA-B*52:01 allele is associated with CC in Japanese women. DESIGN, SETTING, AND PARTICIPANTS This was a multicenter genetic association study. Genotype and phenotype data were obtained from BioBank Japan Project. Additional patients with CC were enrolled from the Aichi Cancer Center Research Institute. An MHC fine-mapping study was conducted on CC risk in the Japanese population by applying a human leukocyte antigen (HLA) imputation method to the large-scale CC genome-wide association study data of using the Japanese population-specific HLA reference panel. Participants included 540 women in BioBank Japan Project with CC or 39 829 women without gynecologic diseases, malignant neoplasms, and MHC-related diseases as controls. An additional 168 patients with CC were recruited from Aichi Cancer Center Research Institute. Histopathological subtypes and clinical stages were not considered. Participants with low genotype call rate, closely related participants, and outliers in the principal component analysis were excluded. Data analysis was performed from August 2018 to January 2020. MAIN OUTCOMES AND MEASURES Loci within the MHC region associated with CC risk, and the direction and size of association. RESULTS A total of 704 CC cases and 39 556 controls were analyzed. All participants were Japanese women with a median (range) age of 67 (18 to 100) years. One of the class I HLA alleles of HLA-B*52:01 was significantly associated with CC risk (odds ratio, 1.60; 95% CI, 1.38-1.86; P = 7.4 × 10-10). Allele frequency spectra of HLA-B*52:01 are heterogeneous among worldwide populations with high frequency in Japanese populations (0.109 in controls), suggesting its population-specific risk associated with CC. The conditional analysis suggested that HLA-B*52:01 could explain most of the MHC risk associated with CC because no other HLA alleles remained significant after conditioning on the HLA-B*52:01. The HLA amino acid residue-based analysis suggested that HLA-B p.Tyr171His located in the peptide-binding groove was associated with the most significant CC risk (odds ratio, 1.47; 95% CI, 1.30-1.66; P = 1.2 × 10-9). CONCLUSIONS AND RELEVANCE The results of this study contribute to understanding of the genetic background of CC. The results suggest that immune responses mediated by class I HLA molecules are associated with susceptibility to CC.

Abstract
Human papilloma virus (HPV) has emerged as a primary cause of cervical cancer worldwide. HPV is a relatively small (55 nm in diameter) and non-enveloped virus containing approximately 8 kb long double stranded circular DNA genome. To date, 228 genotypes of HPV have been identified. Although all HPV infections do not lead to the development of malignancy of cervix, only persistent infection of high-risk types of HPV (mainly with HPV16 and HPV18) results in the disease. In addition, the immunity of the patients also acts as a key determinant in the carcinogenesis. Since, no HPV type specific medication is available for the patient suffering with cervical cancer, hence, a deep understanding of the disease etiology may be vital for developing an effective strategy for its prevention and management. From the immunological perspectives, the entire mechanisms of disease progression still remain unclear despite continuous efforts. In the present review, the recent developments in immunology of HPV-mediated cervix carcinoma were discussed. At the end, the prevention of disease using HPV type specific recombinant vaccines was also highlighted.

Abstract
MYO10, recognized as an important regulator of cytoskeleton remodeling, has been
reported to be associated with tumorigenesis. However, its functional
implication in cervical cancer and potential mechanism still remain to be
undetermined currently. MYO10 level in cervical cancer tissues was analyzed by
using data retrieved from The Cancer Genome Atlas and ONCOMINE databases.
Messenger RNA and protein expression levels were determined by quantitative
real-time polymerase chain reaction and Western blotting. Small-interfering RNA
and overexpressing plasmid were used for MYO10 silencing and overexpression, and
cell proliferation was analyzed by CCK-8. Transwell assays were performed to
investigate the ability of cell migration and invasion. MYO10 was upregulated in
cervical cancer tissues and cells when compared to normal controls, and survival
analysis showed patients with high MYO10 expression had worse overall survival.
Moreover, knockdown/overexpression of MYO10 significantly inhibited/enhanced the
proliferation, invasion, and migration capabilities of cervical cells
transfected with siRNAs/overexpressing plasmid. Additionally, MYO10 silencing
inhibited PI3K/Akt signaling pathway by decreasing the phosphorylation status of
PI3K and AKT. Data from the present study indicated that MYO10 were
overexpressed in patients with cervical cancer and positively linked with poor
prognosis. Experimental results suggested that MYO10 induced a significant
encouraging effect in cervical cancer cell proliferation, invasion, and
migration, linked with involvement of PI3K/Akt signaling. Collectively, these
results emphasize a novel role for MYO10 overexpression in cervical cancer and
provide a potent therapeutic strategy against cervical cancer.

Abstract
SMAD2 is a critical signal transducer molecule in the TGFβ- SMAD pathway which is also known for its tumor suppressor role. Genetic variations in SMAD2 render cells insensitive to its anti-proliferative signals leading to tumor formation. In this study, we demonstrate the impact of single nucleotide polymorphisms (SNPs) of SMAD2 (rs4940086 and rs8085335) on cervical cancer risk development in Bangladeshi population. 132 cervical cancer patients and 98 control volunteers were enrolled in the study and genotyped utilizing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The association between cervical cancer susceptibility and the chosen SNPs were evaluated through multiple logistic regression. SMAD2 rs4940086 heterozygous genotype (T/C) was associated with a 3.89 times higher risk of cervical cancer development (P = 0.001, AOR 3.89, 95% CI 1.777-8.513). The T/C and C/C genotypes in combination also significantly elevated cervical cancer risk (P = 0.035, AOR 1.876, 95% CI 1.047-3.364). Urban cancer patients had a significantly higher chance of carrying the rs4940086 polymorphism as compared to rural cancer patients (P = 0.045, OR 2.59 95% CI 1.02-6.59). SMAD2 rs8085335 heterozygous variant (A/G) demonstrated modest effects in increasing cervical cancer susceptibility (P = 0.594, AOR 1.247, 95% CI 0.554-2.809). Our results suggest that polymorphic variations in SMAD2, particularly rs4940086, can potentially elevate cervical cancer susceptibility in Bangladeshi women.

Abstract
Background Antigen-processing machinery molecules play crucial roles in infectious diseases and cancers. Studies have shown that polymorphisms in endoplasmic reticulum aminopeptidase (ERAP) genes can influence the enzymatic activity of ERAP proteins and are associated with the risk of diseases. In the current study, we evaluated the influence of ERAP gene (ERAP1 and ERAP2) polymorphisms on susceptibility to cervical intraepithelial neoplasia (CIN) and cervical cancer. Methods Six single nucleotide polymorphisms (SNPs) in ERAP1 and 5 SNPs in ERAP2 were selected and genotyped in 556 CIN patients, 1072 cervical cancer patients, and 1262 healthy control individuals. Candidate SNPs were genotyped using SNaPshot assay. And the association of these SNPs with CIN and cervical cancer was analysed. Results The results showed that allelic and genotypic frequencies of rs26653 in ERAP1 were significantly different between cervical cancer and control groups (P = 0.001 and 0.004). The allelic frequencies of rs27044 in ERAP1 and rs2287988 in ERAP2 were significantly different between control and cervical cancer groups (P = 0.003 and 0.004). Inheritance model analysis showed that genotypes of rs27044, rs26618, rs26653 and rs2287988 SNPs may be associated with the risk of cervical cancer (P = 0.003, 0.004, 0.001 and 0.002). Additionally, haplotype analysis results showed that the ERAP1 haplotype, rs27044C-rs30187T-rs26618T-rs26653G-rs3734016C, was associated with a lower risk of cervical cancer (P = 0.001). The ERAP2 haplotypes rs2549782G- rs2548538A-rs2248374A-rs2287988G-rs1056893T (P = 0.009 and 0.006) and rs2549782T-rs2548538T-rs2248374G-rs2287988A-rs1056893T (P = 0.003 and 0.009) might be associated with cervical cancer and the development from CIN to cervical cancer. Conclusion Our results indicated that rs27044, rs26618 and rs26653 in ERAP1 and rs2287988 in ERAP2 influenced susceptibility to cervical cancer.

Abstract
BACKGROUND MicroRNAs (miRNAs) have been increasingly exploited in human malignancies. The regulation of microRNA-455-5p (miR-455-5p) has been shown in several cancers, except for cervical carcinoma. Therefore, the role of miR-455-5p was exploited in cervical carcinoma. METHODS The qRT-PCR experiment was used to assess miR-455-5p and S1PR1 expression levels. We explored the function of miR-455-5p through MTT and Transwell assays. The mTOR pathway and cell apoptosis were detected by Western blot assays. The relationship between miR-455-5p and S1PR1 was testified by dual-luciferase reporter assay. RESULTS MiR-455-5p expression was decreased in cervical carcinoma, which was related to poor clinical outcome in cervical carcinoma patients. MiR-455-5p inhibited cell viability and metastasis in cervical carcinoma. Further, S1PR1 is a direct target of miR-455-5p. S1PR1 recovered the inhibition of cell viability and metastasis induced by miR-455-5p in cervical carcinoma. In addition, miR-455-5p induced cell apoptosis and inactivated the mTOR pathway in cervical carcinoma. CONCLUSION MiR-455-5p exerts inhibitory effect in cervical carcinoma through targeting S1PR1 and blocking the mTOR pathway.

Abstract
Cervical cancer is a common gynecologic malignant tumor with high mortality. HOX transcript antisense RNA (HOTAIR), a trans-acting long non-coding RNA (lncRNA) containing six exons in humans, is transcribed from the antisense strand of homeobox gene C cluster. This lncRNA serves as a modular scaffold for gene silencing and protein ubiquitination. In patients with cervical cancer, elevated HOTAIR levels are significantly associated with poor prognosis. HOTAIR plays an oncogenic role in cervical cancer by promoting cell proliferation, migration, invasion and autophagy, inhibiting cell apoptosis, stimulating angiogenesis, accelerating cell cycle progression, and inducing epithelial-mesenchymal transition. Moreover, blockade of HOTAIR by artesunate or propofol shows promise for further development of this lncRNA as a potential therapeutic target in cervical cancer. In this review, we summarized the latest advances regarding the role of HOTAIR in cervical cancer with an emphasis on its diagnostic and prognostic values.

Abstract
Background: Retinoblastoma protein-interacting zinc finger gene 1 (RIZ1) is a tumor suppressor deregulated in several human cancers. We aim to (1) explore RIZ1 expression in FIGO stages I–II cervical cancer tissues and its association with the clinical outcome of cervical cancer patients, (2) the role of RIZ1 in proliferation, apoptosis, migration, and invasion in cervical cancer cells. Methods: The expression of RIZ1 in 268 cervical cancer tissues and 30 paired adjacent non-tumor tissues were assessed by immunohistochemistry. We also examined RIZ1 at mRNA and protein level in 20 paired fresh frozen cervical cancer tissues and the adjacent non-tumor tissue using real-time PCR and western blot. We then examined proliferation, apoptosis, migration, and invasion in two human cervical cancer cells, HeLa and SiHa, with overexpression of RIZ1. Results: RIZ1 expression generally decreased in cervical cancer tissues. Decreased RIZ1 expression was significantly correlated with advanced FIGO stage (P = 0.005), deep stromal invasion (P = 0.001), lymphovascular space involvement (P = 0.041), pelvic lymph node metastasis (P = 0.005), and postoperative recurrence (P = 0.002). Kaplan-Meier analysis demonstrated that patients with low RIZ1 expression had shorter overall survival (OS) and disease-free survival (DFS) than those with high RIZ1 expression. Multivariate analysis showed that RIZ1 was an independent prognostic factor for DFS (HR = 2.184, 95% CI 1.365–3.496, P = 0.001) and OS (HR = 1.899, 95% CI 1.112–3.241, P = 0.019). In vitro analysis demonstrated that overexpression of RIZ1 inhibited cell proliferation, migration, and invasion, but promoted apoptosis in HeLa and SiHa cells. Conclusion: Down-regulation of RIZ1 may contribute to tumor migration, invasiveness, and poor survival of cervical cancer patients. RIZ1 may be a prognostic biomarker for cervical cancer patients.

Abstract
Previously, a number of microRNAs (miRNAs) have been reported to be dysregulated in cervical cancer, and dysregulated miRNAs may play crucial roles in the development and progression of cervical cancer. Hence, investigating the detailed roles of miRNAs that are aberrantly expressed in cervical cancer and the underlying molecular mechanisms is essential for early diagnosis and effective therapeutic approaches. miRNA-877 (miR-877) was found to be downregulated in hepatocellular carcinoma and renal cell carcinoma, and function as a tumor-suppressive miRNA. However, how miR-877 exerts an effect in cervical cancer progression and its underlying molecular mechanisms remains to be elucidated. In the current study, reverse transcription-quantitative PCR was performed to determine miR-877 expression in cervical cancer tissues and cell lines. The effects of miR-877 overexpression on cervical cancer cell proliferation and invasion were evaluated using MTT and Transwell cell invasion assays. In the present study, miR-877 was significantly downregulated in cervical cancer tissues and cell lines, and the decreased expression levels of miR-877 were significantly associated with increased International Federation of Gynecology and Obstetric stage as well as increased lymph node metastasis in patients with cervical cancer. Upregulation of miR-877 using miR-877 mimics resulted in the decreased proliferation and invasion of cervical cancer cells. Metastasis-associated in colon cancer-1 (MACC1) was assessed using bioinformatics analyses to determine whether it could be a potential target gene of miR-877, and the results were confirmed using a luciferase reporter assay. Furthermore, MACC1 was markedly upregulated in cervical cancer tissues, and its level was negatively correlated with the miR-877 level. Overexpression of miR-877 resulted in decreased expression levels of MACC1 in cervical cancer cells at both the mRNA and protein levels. In addition, the functional effects of MACC1 knockdown were similar to those induced by upregulated miR-877 in cervical cancer cells. MACC1 restored miR-877 overexpression-mediated suppression of cervical cancer cell proliferation and invasion. In conclusion, miR-877 may play an antitumor role in cervical cancer by directly targeting MACC1, which suggests that this miRNA may be a promising therapeutic target for the treatment of patients with such an aggressive gynecological cancer.

Cervical high-risk human papillomavirus infection among women residing in the Gulf Cooperation Council countries: Prevalence, type-specific distribution, and correlation with cervical cytology. Cancer Cytopathol 2019; 127:567-577. [PMID: 31390155 DOI: 10.1002/cncy.22165] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2019] [Revised: 06/16/2019] [Accepted: 07/02/2019] [Indexed: 12/24/2022]
Abstract
BACKGROUND The scarcity of updated data on the prevalence of cervical human papillomavirus (HPV) infection in the Gulf Cooperation Council (GCC) countries hampers the establishment of cervical cancer screening and HPV vaccination programs. The current study estimated the prevalence of cervical high-risk (HR) HPV infection among women residing in some countries of the GCC and analyzed the correlation between HR-HPV infection types and cytology results. METHODS In total, 2478 women residing in the Kingdom of Saudi Arabia, Qatar, the United Arab Emirates, and Bahrain were enrolled in this study. Cervical specimens were subjected to simultaneous liquid-based cytology and HR-HPV DNA analysis. RESULTS Of 2478 women, 520 (21%) tested positive for HR-HPV. Other non-HPV genotype 16 (HPV16)/HPV18 HR-HPV was the most frequently detected infection type, accounting for 63.7%. Non-Arab women had a significantly higher HR-HPV positivity rate compared with Arab women (31.6% vs 16.4%; P < .001). The HR-HPV positivity rate was highest among women residing in Qatar (31.3%), followed by women living in Bahrain (20%), the Kingdom of Saudi Arabia (17.2%), and the United Arab Emirates (14.7%). The overall prevalence of HR-HPV infections declined significantly with advancing age (P < .001). Women with abnormal cytology had a significantly higher HR-HPV positivity rate than those with normal cytology (50.6% vs 14.7%; P < .001). The HR-HPV positivity rate increased as the severity of the cytological lesion increased. CONCLUSIONS The current study provides updated data on HR-HPV prevalence in the GCC countries and delivers an evidence base for supporting the introduction of regional/national vaccination and screening programs in these countries.

Abstract
MicroRNAs (miRNAs) are frequently dysregulated in cervical cancer, and the aberrant regulation of miRNAs may be involved in the regulation of various cancer-associated biological processes. Therefore, further exploration of the specific roles of dysregulated miRNAs in cervical cancer and their associated mechanism may promote the development of effective therapeutic approaches. miRNA-889-3p (miR-889) serves crucial roles in esophageal squamous cell carcinoma and hepatocellular carcinoma. However, to the best of our knowledge, no studies concerning the relationship between miR-889 and cervical cancer were performed. The aims of this study were to measure miR-889 expression in cervical cancer and to examine the potential effects of miR-889 in cervical cancer development on a molecular level to provide potential clinical insight. The present study revealed that miR-889 was downregulated in cervical cancer tissues and cell lines. Reduced miR-889 expression was significantly associated with International Federation of Gynecology and Obstetrics cancer staging and with lymph node metastasis. In addition, miR-889 overexpression reduced cervical cancer cell viability and invasive ability. Using bioinformatics analysis, fibroblast growth factor receptor 2 (FGFR2) was predicted to be a potential target of miR-889, which was confirmed using luciferase reporter assay. Reverse transcription-quantitative PCR and western blot analysis results suggested that miR-889 overexpression decreased FGFR2 expression in cervical cancer cells at the mRNA and the protein level, respectively. Conversely, FGFR2 silencing using small interfering RNA imitated the tumor suppressive effects of miR-889 overexpression in cervical cancer cells, which was successfully reversed by plasmid-facilitated FGFR2 overexpression. These observations demonstrated that miR-889 may serve tumor suppressive roles in cervical cancer by directly targeting FGFR2, which indicated that this miRNA may be a promising therapeutic target for patients with cervical cancer.

Abstract
The development of cervical cancer is initiated by human papillomavirus (HPV) infection and involves both viral and host genetic factors. Genome-wide association studies (GWAS) of cervical cancer have identified associations in the HLA locus and two loci outside HLA, but the principal genes that control infection and pathogenesis have not been identified. In the present study, we performed GWAS of cervical cancer in East Asian populations, involving 2609 cases and 4712 controls in the discovery stage and 1461 cases and 3295 controls in the follow-up stage. We identified novel-significant associations at 5q14 with the lead single nucleotide polymorphism (SNP) rs59661306 (P = 2.4 × 10-11) and at 7p11 with the lead SNP rs7457728 (P = 1.2 × 10-8). In 5q14, the chromatin region of the GWAS-significant SNPs was found to be in contact with the promoter of the ARRDC3 (arrestin domain-containing 3) gene. In our functional studies, ARRDC3 knockdown in HeLa cells caused significant reductions in both cell growth and susceptibility to HPV16 pseudovirion infection, suggesting that ARRDC3 is involved in the infectious entry of HPV into the cell. Our study advances the understanding of host genes that are responsible for cervical cancer susceptibility and guides future research on HPV infection and cancer development.

Up-regulation of miRNA-148a inhibits proliferation, invasion, and migration while promoting apoptosis of cervical cancer cells by down-regulating RRS1. Biosci Rep 2019; 39:BSR20181815. [PMID: 30910849 PMCID: PMC6505193 DOI: 10.1042/bsr20181815] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 03/03/2019] [Accepted: 03/04/2019] [Indexed: 02/07/2023] Open
Abstract
The purpose of the present study is to figure out the role of miRNA-148a (miR-148a) in growth, apoptosis, invasion, and migration of cervical cancer cells by binding to regulator of ribosome synthesis 1 (RRS1). Cervical cancer and adjacent normal tissues, as well as cervical cancer cell line Caski, HeLa, C-33A, and normal cervical epithelial cell line H8 were obtained to detect the expression of miR-148a and RRS1. Relationship between miR-148a and RRS1 expression with clinicopathological characteristics was assessed. The selected Caski and HeLa cells were then transfected with miR-148a mimics, miR-148a inhibitors or RRS1 siRNA to investigate the role of miR-148a and RRS1 on proliferation, apoptosis, colony formation, invasion, and migration abilities of cervical cancer cells. Bioinformatics information and dual luciferase reporter gene assay was for used to detect the targetting relationship between miR-148a and RRS1. Down-regulated miR-148a and up-regulated RRS1 were found in cervical cancer tissues and cells. Down-regulated miR-148a and up-regulated RRS1 are closely related with prognostic factors of cervical cancer. RRS1 was determined as a target gene of miR-148a and miR-148a inhibited RRS1 expression in cervical cancer cells. Up-regulation of miR-148a inhibited cell proliferation, migration, and invasion while promoting apoptosis in Caski and HeLa cells. Our study suggests that miR-148a down-regulates RRS1 expression, thereby inhibiting the proliferation, migration, and invasion while promoting cell apoptosis of cervical cancer cells.

Classical HLA alleles are associated with prevalent and persistent cervical high-risk HPV infection in African women. Hum Immunol 2019; 80:723-730. [PMID: 31072753 DOI: 10.1016/j.humimm.2019.04.011] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 04/04/2019] [Accepted: 04/15/2019] [Indexed: 12/24/2022]
Abstract
BACKGROUND Persistent cervical high-risk human papillomavirus (hrHPV) infection is a necessary cause of cervical cancer. However, the host genetic factors underlying its risk are not well understood. We hypothesized that immunogenetic variation plays a role in hrHPV infection and persistence. Therefore, we conducted a study of classical HLA alleles and their association with hrHPV infection and persistence among women. METHODS We characterized HPV infection using SPF10/LiPA25in Nigerian women at baseline and at 6 months follow-up visits in 2014. hrHPV infection was prevalent if at least one carcinogenic HPV genotype was detected at the baseline visit and persistent if at least one carcinogenic HPV genotype was detected at the baseline and follow-up visits. Classical HLA alleles were imputed from genotypes in the MHC region using the HLA genotype imputation with attribute bagging (HIBAG) algorithm. HLA association tests were conducted under additive genetic models. RESULTS The mean (±SD) age of the 517 study participants was 38 (±8) years, 48% were HIV negative, 24% were hrHPV positive at baseline and 10% had persistent hrHPV infections. In multivariate regression models adjusted for age, HIV status and the first principal component, DQA1*01:02 and DQA1*02:01 were positively associated with prevalent but not persistent hrHPV infections, while DQA1*05:01 was negatively associated with prevalent hrHPV but positively associated with persistent cervical hrHPV infections. Four haplotypes (A*30:01-DQA1*05:01, B*07:02-C*07:02, B*07:02-DQA1*05:01 and C*07:02-DQA1*05:01) were significantly associated with prevalent cervical hrHPV infections and several haplotypes that included the DQA1*05:01 allelic variant were significantly associated with persistent cervical hrHPV infections. Six amino acid positions on DQα1 were associated with prevalent but not persistent cervical hrHPV infections. CONCLUSIONS In this first study to investigate the association between HLA alleles and persistent hrHPV in African women, we identified important risk alleles that merit further investigation. Our findings provide new insights into risk factors for hrHPV infection in African ancestry women.

Abstract
Objectives: Understanding the prevalence and characteristics of high-risk human papillomavirus (hrHPV) with the large-scale multicenter data based on a US FDA-approved testing method is important to guide ongoing vaccination programs in China. Methods: We conducted a retrospective observational study based on data from 11 large hospitals in central and eastern China. From October 1st, 2012 to December 31st, 2016, a total of 480,034 cervical specimens were collected, and 414,540 eligible participants (14-80 years, mean age 39.9 years) were included and tested using Cervista High-Risk HPV Assay (Hologic Inc., Bedford, Mass, USA). Results: The overall hrHPV prevalence in this study was 17.8% (73,713/414,540), with Wuhan slightly higher than Zhejiang (18.6% vs. 17.6%, P < 0.001). The prevalence showed a declining trend from 2012 to 2016. The most common hrHPV group was A9 (61.7%), followed by A5/A6 (29.4%) and A7 (25.6%). A U-shaped curve was observed for age-specific hrHPV prevalence: ≤19 years and ≥50 years were higher than other age groups. Conclusion: In pre-vaccination period, A9 was the most dominant hrHPV group, and infections were most likely to occur at younger and older ages. The prevalence of hrHPV varied by cities and age groups, suggesting vaccination programs should be propagated in a population-specific approach.

Abstract
Persistent high-risk human papillomavirus (HPV) infection has been associated with increased risk for cervical precancerous lesions and cancer. The host's genetic variability is known to play a role in the development of cervical cancer. The human leukocyte antigen (HLA) genes are highly polymorphic and have shown to be important risk determinants of HPV infection persistence and disease progression. HLA class I and II cell surface molecules regulate the host's immune system by presenting HPV-derived peptides to T-cells. The activation of T-cell response may vary depending on the HLA allele polymorphism. The engagement of the T-cell receptor with the HPV peptide-HLA complex to create an active costimulatory signal is essential for the activation of the T-cell response. Functional peptide presentation by both HLA class I and II molecules is needed to activate efficient helper and effector T-cell responses in HPV infection recognition and clearance. Some of these HLA risk alleles could also be used as preventive tools in the detection of HPV-induced cervical lesions and cancer. These HLA alleles, together with HPV vaccines, could potentially offer possible solutions for reducing HPV-induced cervical cancer as well as other HPV-related cancers.

Abstract
AIM Whether young cervical cancer patients have poorer prognosis compared to older ones has remained controversial over the past half century. The last three decades have seen a rise in morbidity and mortality among young Japanese women with cervical cancer. This reflects the fact that the importance of prevention has not been fully recognized due to limited clinical studies. We examined the relationship between age and prognosis in cervical cancer. METHODS We retrospectively examined medical records of consecutive patients with International Federation of Gynecology and Obstetrics stage IB and IIB cervical cancer at a hospital in Japan. Patients were divided into two age groups: less than or equal to 39 years (adolescent and young adult [AYA] group) and greater than or equal to 40 years (older adult group). We compared prognosis and clinical factors associated with prognosis between AYA and older adult patients. RESULTS Data from 182 patients (AYA n = 71; older adults n = 111) treated between 2004 and 2011 were analyzed. The proportion of loss to follow-up was 6.0%. Significant differences were observed in stage and lymph node metastasis between the two groups at baseline. However, despite the older adult group having a higher proportion of advanced cancer patients, the overall survival rate of stage IIB patients in the AYA group at the 3-year follow-up was significantly lower (AYA 53.6%, older adults 86.3%, P < 0.05). Multivariate analysis adjusted for clinical factors revealed that AYA patients had a 3.7-3.9 times greater mortality risk compared to older adults. CONCLUSION AYA patients with stage IB and IIB cervical cancer may have a prognostic disadvantage.

Abstract
Background miRNAs have been found to be dysregulated in cervical cancer. The dysregulation of miRNA has been implicated in cervical carcinogenesis and progression. Therefore, further studies of the specific roles of deregulated miRNAs in cervical cancer and underlying molecular mechanisms may facilitate the identification of novel therapeutic techniques for patients with this disease. miRNA-641 (miR-641) was previously reported to serve an important role in lung cancer. However, the expression pattern and roles of miR-641 in cervical cancer remain unclear. Method In this study, the expression level of miR-641 in cervical cancer tissues and cell lines was detected using RT-qPCR. The influence of miR-641 upregulation in cervical cancer cell proliferation, apoptosis, migration and invasion was evaluated using CCK-8 assay, flow cytometry assay, migration and invasion assays, respectively. In vivo tumor growth assay was utilized to determine the effect of miR-641 overexpression in the tumor growth of cervical cancer cells in vivo. The molecular mechanisms underlying the action of miR-641 in cervical cancer cells were also explored. Results We found that miR-641 expression was obviously decreased in cervical cancer tissues and cell lines, which strongly correlated with the International Federation of Gynecology and Obstetrics stage and lymph node metastasis. Upregulation of miR-641 inhibited cell proliferation, induced apoptosis, and reduced metastasis in cervical cancer. Additionally, bioinformatics analysis predicted ZEB1 as a novel target gene of miR-641. Notably, luciferase reporter assay, RT-qPCR, and Western blot analysis revealed that miR-641 decreased ZEB1 expression in cervical cancer cells by directly targeting its 3'-untranslated region. Furthermore, ZEB1 was upregulated in cervical cancer tissues, which was negatively correlated with miR-641 expression. Moreover, recovered ZEB1 expression attenuated the tumor suppressive action of miR-641 overexpression in the malignant phenotypes of cervical cancer cells. Besides, miR-641 could hinder cervical cancer tumor growth in vivo by inhibiting ZEB1. Conclusion These results indicate that miR-641 has tumor suppressive roles in the development of cervical cancer by directly targeting ZEB1, suggesting that miR-641 is a novel, effective therapeutic target for treating patients with this disease.

Abstract
Genetic epidemiological studies show that genetic factors contribute significantly to cervical cancer carcinogenesis. Several genome-wide association studies (GWAS) have revealed novel genetic variants associated with cervical cancer susceptibility. We aim to replicate 4 GWAS-identified single nucleotide polymorphisms (SNPs), which were associated with invasive cervical cancer in Chinese women, in a Taiwanese population. The rs13117307 C/T, rs8067378 A/G, rs4282438 G/T, and rs9277952 A/G SNPs were genotyped in 507 women with cervical squamous cell carcinoma (CSCC) and 432 age/sex matched healthy controls by using TaqMan PCR Assay. Human papillomavirus (HPV) DNA test and typing were performed in CSCC patients. Only the rs4282438 SNP was found to be significantly associated (G allele, odds ratio [OR] = 0.67, P = 1.5 × 10−5). This protective association remained in HPV-16 positive CSCC subgroup (G allele, OR = 0.60, P = 1.2 × 10−5). In conclusion, our study confirms the association of rs4282438 SNP with CSCC in a Taiwanese population. However, larger sample sets of other ethnic groups are required to confirm these findings.

Naturally Occurring Variations Modulate the Activity of the HPV33 Early Promoter and its Affinity for the E2 Transcription Factor. Sci Rep 2018; 8:15015.

Abstract
The human papillomavirus (HPV) Long Control Region (LCR) encompasses the early promoter (EP) that drives transcription of the E6 and E7 oncogenes in keratinocytes and HPV-associated cancers. In this study, the transcriptional activities of the HPV33 EP from the prototype LCR and from eight variants representative of the worldwide diversity of the virus were examined in primary human keratinocytes (PHK) and in the HeLa cervical carcinoma cell line by luciferase reporter-gene assays. Remarkably, the two variations with the greatest effect on the EP in PHK were C7732G and a 79-bp deletion that were associated with high-grade cervical lesions and persistent infections, respectively, in epidemiological studies. In contrast, the three variations most active in HeLa cells were C7537A, A7874C and A7879G. A7874C, which lies within an E2-binding sequence, is also shown to increase the activity and binding of E2 at this site. Collectively, these results indicate that naturally-occurring variations affect the HPV33 EP differentially in PHK than in cancer cells and, furthermore, that they can also alter its regulation by E2. These findings provide a molecular basis for rationalizing the results of previous epidemiological studies and for understanding the contribution of LCR polymorphisms to the oncogenicity and persistence of HPV33 infections.

Abstract
A number of studies have revealed the significance of microRNAs (miRs) in tumorigenesis. Cervical cancer (CC) is one of the most malignant cancer types and is associated with a poor overall survival rate. A previous study demonstrated a critical role of miR-214 in the development of multiple cancer types, but its role in CC remains elusive. In the current study, miR-214 was observed to be downregulated in CC tissues compared with the adjacent non-cancerous tissue. Overexpression of miR-214 reduced the proliferation of CC cells, whereas inhibiting its expression resulted in enhanced proliferation. Furthermore, Enhancer of zeste homolog 2 (EZH2) was demonstrated to be a direct target of miR-214 in CC. An MTT assay demonstrated that upregulating miR-214 expression or knocking down the expression of EZH2 impaired the proliferation of a CC cell line. Low expression of miR-214 was positively associated with tumor differentiation (P=0.037) and tumor stage (P=0.012). Notably, low expression of miR-214 predicted poor prognosis of patients with CC. Consequently, the results of the current study demonstrated that miR-214 functions as a tumor suppressor in CC and may be regarded as a potential therapeutic target in CC.

Two HLA Class II Gene Variants Are Independently Associated with Pediatric Osteosarcoma Risk. Cancer Epidemiol Biomarkers Prev 2018; 27:1151-1158. [PMID: 30038050 DOI: 10.1158/1055-9965.epi-18-0306] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2018] [Revised: 05/29/2018] [Accepted: 07/09/2018] [Indexed: 12/18/2022] Open
Abstract
Background: The genetic etiology of osteosarcoma remains poorly understood despite the publication of a genome-wide association study. Association between HLA genetic variants and risk of several cancers has been observed, but HLA variation is not well captured by standard SNP arrays.Methods: We genotyped 207 Californian pediatric osteosarcoma cases and 696 controls of European ancestry using a custom genome-wide array supplemented with approximately 6,000 additional probes across the MHC region. We subsequently imputed 4-digit classical HLA alleles using a reference panel of 5,225 individuals who underwent high-resolution HLA typing via next-generation sequencing. Case-control comparisons were adjusted for ancestry-informative principal components, and top associations from the discovery analysis underwent replication in an independent dataset of 657 cases and 1,183 controls.Results: Three highly correlated HLA class II variants (r 2 = 0.33-0.98) were associated with osteosarcoma risk in discovery analyses, including HLA-DRB1*0301 (OR = 0.52; P = 3.2 × 10-3), HLA-DQA1*0501 (OR = 0.74; P = 0.031), and HLA-DQB1*0201 (OR = 0.51; P = 2.7 × 10-3). Similar associations were observed in the replication data (P range = 0.011-0.037). Meta-analysis of the two datasets identified HLA-DRB1*0301 as the most significantly associated variant (ORmeta = 0.62; P meta = 1.5 × 10-4), reaching Bonferroni-corrected statistical significance. The meta-analysis also revealed a second significant independent signal at HLA-DQA1*01:01 (ORmeta = 1.33, P meta = 1.2 × 10-3), and a third suggestive association at HLA-DQB1*0302 (ORmeta = 0.73, P meta = 6.4 × 10-3).Conclusions: Multiple independent HLA class II alleles may influence osteosarcoma risk.Impact: Additional work is needed to extend our observations to other patient populations and to clarify the potential causal mechanisms underlying these associations. Understanding immunologic contributions to the etiology of osteosarcoma may inform rational therapeutic targets. Cancer Epidemiol Biomarkers Prev; 27(10); 1151-8. ©2018 AACR.

Abstract
Objective. We aimed to derive a more precise estimation of the associations between human leukocyte antigens DP (HLA-DP) gene polymorphisms and cervical cancer risk by meta-analysis. Methods. PubMed, EMBASE, ScienceDirect, Web of Science, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases were systematically searched to identify studies investigating the relationship between HLA-DP gene polymorphisms and cervical cancer. The associations between them were evaluated by pooled OR and 95% CI. Results. A total of 11 studies including 5008 cases and 9322 controls with 11 HLA-DP alleles were included in the current meta-analysis. Results. The results showed that HLA-DPB1⁎03:01 was significantly associated with an increased risk of cervical cancer (OR=1.252, 95%CI: 1.116-1.403, Pz=0.001), while HLA-DPB1⁎04:02 and HLA-DP rs3117027 G allele were significantly associated with a decreased risk of cervical cancer (OR=0.744, 95%CI: 0.652-0.848, Pz=0.001; OR=0.790, 95%CI: 0.745-0.837, Pz=0.001), and HLA-DP rs9277535 G allele was significantly associated with a decreased risk of cervical cancer in Asia (OR=0.802, 95%CI: 0.753-0.855, Pz=0.001). Subgroup analyses based on race system showed that HLA-DPB1⁎13:01 was significantly associated with an increased risk of cervical cancer in Asia (OR=1.834, 95%CI: 1.107-3.039, Pz=0.019). No significant association was established for the HLA-DP following alleles: DPB1⁎02:01, DPB1⁎02:02, DPB1⁎04:01, DPB1⁎05:01, rs4282438, and rs3077. Conclusion. HLA-DP gene polymorphisms (HLA-DPB1⁎03:01, DPB1⁎04:02, DPB1⁎13:01, rs9277535, and rs3117027) were significantly associated with cervical cancer.

High Rate of Infection by Only Oncogenic Human Papillomavirus in Amerindians. mSphere 2018; 3:3/3/e00176-18.

Abstract
The role of HPV type distribution on the disparity of cervical cancer (CC) incidence between human populations remains unknown. The incidence of CC in the Amazonas State of Venezuela is higher than the national average. In this study, we determined the diversity of known HPV types (the viral agent of CC) in Amerindian and mestizo women living in the Venezuelan Amazonas State. Understanding the ecological diversity of HPV in populations undergoing lifestyle transformations has important implication on public health measures for cervical cancer prevention. Human papillomavirus (HPV), an etiological agent of cervical cancer (CC), has infected humans since ancient times. Amerindians are the furthest migrants out of Africa, and they reached the Americas more than 14,000 years ago. Some groups still remain isolated, and some migrate to towns, forming a gradient spanning urbanization. We hypothesized that, by virtue of their history, lifestyle, and isolation from the global society, remote Amerindian women have lower HPV diversity than do urban women (Amerindian or mestizo). Here we determined the diversity of the 25 most relevant cervical HPV types in 82 Amerindians spanning urbanization (low, medium, and high, consistent with the exposure to urban lifestyles of the town of Puerto Ayacucho in the Venezuelan Amazonas State), and in 29 urban mestizos from the town. Cervical, anal, oral, and introitus samples were taken, and HPVs were typed using reverse DNA hybridization. A total of 23 HPV types were detected, including 11 oncogenic or high-risk types, most associated with CC. Cervical HPV prevalence was 75%, with no differences by group, but Amerindians from low and medium urbanization level had significantly lower HPV diversity than mestizos did. In Amerindians, but not in mestizos, infections by only high-risk HPVs were higher than coinfections or by exclusively low-risk HPVs. Cervical abnormalities only were observed in Amerindians (9/82), consistent with their high HPV infection. The lower cervical HPV diversity in more isolated Amerindians is consistent with their lower exposure to the global pool, and transculturation to urban lifestyles could have implications on HPV ecology, infection, and virulence. IMPORTANCE The role of HPV type distribution on the disparity of cervical cancer (CC) incidence between human populations remains unknown. The incidence of CC in the Amazonas State of Venezuela is higher than the national average. In this study, we determined the diversity of known HPV types (the viral agent of CC) in Amerindian and mestizo women living in the Venezuelan Amazonas State.

Abstract
A large number of microRNAs (miRNAs) are aberrantly expressed in cervical cancer and play crucial roles in the onset and progression of cervical cancer by acting as either an oncogene or a tumor suppressor. Therefore, investigation of the expression, biological roles, and underlying mechanisms of miRNAs in cervical cancer might provide valuable therapeutic targets in the treatment for patients with this disease. In this study, miRNA-377 (miR-377) was downregulated in cervical cancer tissues and cell lines. Decreased miR-377 expression was strongly correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis, and distant metastasis in patients with cervical cancer. Enhanced expression of miR-377 prohibited cell proliferation and invasion in cervical cancer. Bioinformatics analysis predicted that zinc finger E-box-binding homeobox 2 (ZEB2) was a potential target of miR-377. Subsequent experiments confirmed that ZEB2 is a direct target gene of miR-377 in cervical cancer. In addition, ZEB2 was overexpressed in cervical cancer tissues and was inversely related with miR-377 levels. Furthermore, the suppressive effects of miR-377 on cervical cancer proliferation and invasion were rescued by restored ZEB2 expression. Overall, our findings indicated that miR-377 decreases proliferation and invasion of cervical cancer cells by directly targeting ZEB2 and provides novel evidence of miR-377 as a novel therapeutic strategy for the therapy of patients with this malignancy.

Abstract
Ribonucleotide reductase subunit M2 (RRM2) is associated with the biological behaviours of cancers, including apoptosis, cell proliferation, invasion, cell cycle and migration. Previous studies have suggested that the expression of RRM2 plays critical roles in tumorigenesis in several cancer types. However, the precise molecular mechanism remains unknown. We previously identified RRM2 as a novel downstream target that is activated by human papillomavirus E7, which activates the extracellular signal-regulated kinase 1/2 signalling pathway, but further studies are warranted to establish RRM2 as a therapeutic target. The results of the present study indicate that RRM2 is associated with cervical cancer cell apoptosis and proliferation. The downregulation of RRM2 significantly increased apoptosis, promoted cell cycle arrest at the G1 phase in vitro and inhibited tumour formation in nude mice transplant models in vivo. These results highlight the potential for inhibition of RRM2 expression as a promising therapeutic target for human cervical cancer treatment.

Abstract
Recent genome-wide association studies (GWASs) in subjects of European descent have identified associations between cervical cancer risk and three independent loci as well as multiple classical human leukocyte antigen (HLA) alleles at 6p21.3. To search for novel loci associated with development of cervical cancer, we performed a pooled analysis of data from two GWASs by imputing over 10 million genetic variants and 424 classical HLA alleles, for 1,553 intraepithelial neoplasia 3 (CIN3), 81 cervical cancer and 4,442 controls from the Swedish population. Notable findings were validated in an independent study of 961 patients (827 with CIN3 and 123 with cervical cancer) and 1,725 controls. Our data provided increased support for previously identified loci at 6p21.3 (rs9271898, P = 1.2 × 10−24; rs2516448, 1.1 × 10−15; and rs3130196, 2.3 × 10−9, respectively) and also confirmed associations with reported classical HLA alleles including HLA-B*07:02, -B*15:01, -DRB1*13:01, -DRB1*15:01, -DQA1*01:03, -DQB1*06:03 and -DQB1*06:02. In addition, we identified and subsequently replicated an independent signal at rs73730372 at 6p21.3 (odds ratio = 0.60, 95% confidence interval = 0.54–0.67, P = 3.0 × 10−19), which was found to be an expression quantitative trait locus (eQTL) of both HLA-DQA1 and HLA-DQB1. This is one of the strongest common genetic protective variants identified so far for CIN3. We also found HLA-C*07:02 to be associated with risk of CIN3. The present study provides new insights into pathogenesis of CIN3.

Abstract
The aim of this study was to determine the possible involvement of human papillomavirus and Epstein-Barr virus in esophageal squamous cell cancer (ESCC) carcinogenesis in the Greek population. DNA was extracted from 30 ESCC and 27 normal esophageal specimens and screened for HPV type-specific or EBV infection by PCR-based assay. Seventeen out of 30 ESCC specimens (56%) were found positive for HPV DNA, of which 15 (88%) were typed as HPV-18 infected, one (5.9%) as HPV-16 infected, and one (5.9%) as infected by an HPV type different from the studied HPV-6, 11, 16, 18 and 33 subtypes. Six of the 27 normal esophageal specimens (22.2%) were positive for HPV infection, five typed as HPV-18 (83.3%) and one as HPV-16 (16.7%). All samples were negative for EBV genome detection as assessed by the PCR assay. No statistically significant correlation was found between the HPV status of the tumor samples and clinical parameters including sex, age of the patients, tobacco or alcohol use, differentiation grade of the lesions and stage of the disease. In conclusion, our findings indicate a statistically significant (p<0.001) overall association between ESCC and HPV infection, mostly related to the HPV-18 subtype, in the Greek population.

Mitochondrial DNA ancestry, HPV infection and the risk of cervical cancer in a multiethnic population of northeastern Argentina. PLoS One 2018; 13:e0190966. [PMID: 29329337 PMCID: PMC5766133 DOI: 10.1371/journal.pone.0190966] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Accepted: 12/22/2017] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Misiones Province in northeastern Argentina is considered to be a region with a high prevalence of HPV infection and a high mortality rate due to cervical cancer. The reasons for this epidemiological trend are not completely understood. To gain insight into this problem, we explored the relationship between mitochondrial DNA (mtDNA) ancestry, HPV infection, and development of cervical lesions/cancer in women from the city of Posadas in Misiones Province. METHODS Two hundred and sixty-one women, including 92 cases of patients diagnosed with cervical lesions and 169 controls, were analyzed. mtDNA ancestry was assessed through HVS1 sequencing, while the detection and typing of HPV infection was conducted through nested multiplex PCR analysis. Multivariate logistic regression was conducted with the resulting data to estimate the odds ratios (ORs) adjusted by socio-demographic variables. RESULTS The study participants showed 68.6% Amerindian, 26.1% European and 5.3% African mtDNA ancestry, respectively. Multiple regression analysis showed that women with African mtDNAs were three times more likely to develop a cervical lesion than those with Native American or European mtDNAs [OR of 3.8 (1.2-11.5) for ancestry and OR of 3.5 (1.0-12.0) for L haplogroups], although the associated p values were not significant when tested under more complex multivariate models. HPV infection and the development of cervical lesions/cancer were significant for all tested models, with the highest OR values for HPV16 [OR of 24.2 (9.3-62.7)] and HPV-58 [OR of 19.0 (2.4-147.7)]. CONCLUSION HPV infection remains a central risk factor for cervical cancer in the Posadas population. The potential role of African mtDNA ancestry opens a new avenue for future medical association studies in multiethnic populations, and will require further confirmation in large-scale studies.

Genetics and epigenetics in the pathogenesis of primary biliary cholangitis. Clin J Gastroenterol 2017; 11:11-18. [PMID: 29159718 DOI: 10.1007/s12328-017-0799-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Accepted: 11/05/2017] [Indexed: 02/07/2023]
Abstract
Primary biliary cholangitis (PBC) is a chronic, slowly progressive cholestatic autoimmune liver disease predominantly afflicting women. PBC is characterized by the presence of disease-specific antimitochondrial antibodies and the histological destruction of intrahepatic bile ducts, which eventually lead to cirrhosis and hepatic failure. Fortunately, ursodeoxycholic acid therapy has improved the outcome of the vast majority of PBC cases. Although the etiology of PBC has not yet been elucidated, human leukocyte antigen (HLA) class II alleles have been consistently associated with disease onset for decades. PBC patients may also have genetically determined risk factors in non-HLA regions. Meanwhile, exposure to environmental factors, such as infectious diseases and harmful chemicals, can produce epigenetic alterations in some individuals and subsequent PBC onset. In this review, we describe the influence of HLA alleles and other gene polymorphisms on PBC along with the results of genome-wide association studies on this disease and its future prospects in terms of epigenetics.
