[PMID: 36059664 PMCID: PMC9437333 DOI: 10.3389/fonc.2022.973077] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 08/01/2022] [Indexed: 12/24/2022] Open
Abstract
BackgroundAlthough the association between MDM2 rs2279744 and TP53 rs1042522 polymorphisms and cervical cancer has been reported, the results of its correlation were contradictory. Thus, we conducted a meta-analysis to precisely verify the relationships between MDM2 rs2279744 and TP53 rs1042522 polymorphisms and cervical cancer.MethodsWe thoroughly searched the PubMed, Web of Science, Embase, and Scopus databases for all potential articles from inception to June 2022 and used R Version 4.1.2 and STATA software 12.0 for the meta-analysis. The odds ratios (ORs), 95% confidence intervals (CIs) and 95% prediction intervals (PIs) were calculated to evaluate the associations. Subgroup analyses stratified by ethnicity, source of control, quality score and adjustment were further conducted to assess the relationship between MDM2 rs2279744 and TP53 rs1042522 polymorphisms and cervical cancer.ResultsA total of 30 case-control studies involving 5025 cases and 6680 controls were included. All the included studies were population-based or hospital-based studies. The overall analysis showed that MDM2 rs2279744 polymorphism was closely related to an increased risk of cervical cancer in the recessive model (GG vs GT + TT: OR = 1.602, 95% CI: 1.077-2.383, P = 0.020) and homozygote model (GG vs TT: OR = 1.469, 95% CI: 1.031-2.095, P = 0.033, 95% PI: 0.516-4.184). A significant correlation between TP53 rs1042522 polymorphism and cervical cancer was observed in two models (CC + CG vs GG: OR = 1.759, 95% CI: 1.192-2.596, P = 0.004, 95% PI: 0.474-6.533; GG vs CC: OR = 2.442, 95% CI: 1.433-4.162, P = 0.001, 95% PI: 0.456-13.071).ConclusionsThis meta-analysis revealed that MDM2 SNP309T>G and TP53 rs1042522 C>G polymorphisms were associated with the increased risk of cervical cancer.

Abstract
Recent studies have indicated that long noncoding RNA (lncRNA) and N6-methyladenosine (m6A) methylation modification play critical roles in human cancers; however, their regulation on cervical cancer is largely unclear. Here, our study tries to investigate the underlying mechanisms by which lncRNA FOXD2 adjacent opposite strand RNA 1 (FOXD2-AS1) modulates cervical cancer tumorigenesis. Results illuminated that FOXD2-AS1 expression was significantly upregulated in cervical cancer cells and tissue, which was closely correlated to the unfavorable prognosis. Functionally, gain and loss-of-function assays showed that FOXD2-AS1 promoted the migration and proliferation of cervical cancer cells. Besides, FOXD2-AS1 silencing repressed the tumor growth in vivo. Mechanistically, m6A methyltransferase methyltransferase-like 3 (METTL3) enhanced the stability of FOXD2-AS1 and maintained its expression. Moreover, FOXD2-AS1 recruited lysine-specific demethylase 1 (LSD1) to the promoter region of p21 to silence its transcription abundance. In conclusion, these findings support that METTL3/FOXD2-AS1 accelerates cervical cancer progression via a m6A-dependent modality, which may serve as a potential therapeutic target for cervical cancer.

Abstract
OBJECTIVE TP53 plays a crucial role in preventing cancer development. Previous studies in sub-Saharan Africa (SSA) reported inconclusive findings for the association of the TP53 rs1042522 C > G variant with cervical cancer. We therefore performed a meta-analysis to summarise this association in the SSA population. METHODS Online databases were searched to identify suitable articles according to the PRISMA guidelines. We included studies published in English or French that provided the sample sizes and genotype counts for both cases and controls and evaluated the association between TP53 rs1042522 and cervical cancer in the SSA population. A fixed-effect model was used to calculate the pooled odds ratio (OR) and 95% confidence intervals (95% CIs). RESULTS A total of 699 cervical cancer cases and 1008 controls from eight studies in SSA were included in this meta-analysis. Women harbouring the variant G allele of the TP53 rs1042522 were at increased risk of cervical cancer in allelic (G vs. C; OR = 1.30, 95% Cl = 1.12-1.50), homozygous (GG vs. CC; OR = 1.62, 95% CI = 1.20-2.19) and recessive (GG vs. CG + GG; OR = 1.74, 95% CI = 1.34-2.25) genetic models. However, the dominant genetic model (CG + GG vs. CC; OR = 1.20, 95% CI = 0.96-1.48) was not significantly associated with cervical cancer. CONCLUSIONS Our meta-analysis revealed that harbouring variant G allele of TP53 rs1042522 is associated with cervical cancer risk in the SSA population.

Abstract
The aim of the present study was to investigate the regulation of stromal cell‑derived factor 1 (CXCL12) in the radioresistance of cervical cancer, which was upregulated in tumors in our previous study. A CCK‑8 assay was used to detect cell viability. Flow cytometry was used to measure cell apoptosis and the expression levels of CD44 and CXCR4. ELISA was performed to measure the expression level of CXCL12 protein and CXCL12 mRNA was detected by reverse transcription‑quantitative polymerase chain reaction assays. Cell viability and apoptosis were determined with or without treatment with CXCL12 small interfering (si)RNA to examine the function of CXCL12 in Hela cells. The expression level of CD44 antigen (CD44) and C‑X‑C chemokine receptor type 4 (CXCR4) were measured using flow cytometry in the presence of CXCL12 and irradiation. In the present study, it was demonstrated that inhibition of CXCL12 reduced cell viability and increased cellular apoptosis in Hela cells treated with irradiation. Following treatment with CXCL12 siRNA, the expression level of CD44 was downregulated and the expression level of CXCR4 was upregulated. This effect of regulation additionally occurred in the presence of irradiation. In conclusion, the present data demonstrated that CXCL12 served an important role in the radioresistance of cervical cancer, suggestinh a novel therapeutic target.

Abstract
Infection by high-risk human papillomavirus (HR-HPV) and single nucleotide polymorphism (SNP) in genes involved in cell cycle control, as p21 and p27, are important factors in the development of different types of human cancers. This study aims at investigating whether both the p21 Ser31Arg and p27 V109G polymorphisms are associated with susceptibility to the development of cervical lesions in women HR-HPV positive. We analyzed 132 women HPV positive and with cervical lesions or CC and 154 healthy control (HPV negative and without cervical lesions). p21 Ser31Arg and p27 V109G polymorphisms were analyzed using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method and sequencing. The p21 31Arg allele was associated with susceptibility for the development of cervical lesions (P* = 0.0009), while p27 V109G polymorphism showed no significant differences for this association (P* = 0.89). However, the combined effect of the polymorphisms showed that the presence of the CC genotype (SNP p21 Ser31Arg) conferred protection for the development of cervical lesions (OR = 0.39). p21 Ser31Arg and p27 V109G polymorphisms were not associated with the grade of cervical lesions (CINI, CINII, and CINIII) or CC (P* > 0.05). The HR-HPV more frequent in this study were of 16 (57.6 %) and 18 (37.1 %) types; however, no association was observed when both polymorphisms and risk factors analyzed were compared (P* > 0.05). Our findings suggest a possible association between p21 Ser31tabArg polymorphism and susceptibility to the development of cervical lesions in women from Pernambuco. Brazil.

Abstract
The CDKN1A gene product is a p53 downstream effector, which participates in cell differentiation, development process, repair, apoptosis, senescence, migration, and tumorigenesis. The objective of our study was investigated the importance of two polymorphisms in the CDKN1A gene, rs1801270 (31C>A) and rs1059234 (70C>T), for the development of cervical lesions in a Southeastern Brazilian population (283 cases, stratified by lesion severity, and 189 controls). CDKN1A genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and/or DNA sequencing. CDKN1A 31A allele presents a genetic pattern of protection for the development of high-grade cervical lesions (CC vs CA genotype: OR = 0.60; 95 % CI = 0.38-0.95; p = 0.029; CA+AA vs CC genotype: OR = 0.60; 95 % CI = 0.39-0.93; p = 0.021). Allele distributions of the CDKN1A 70C>T polymorphism were also different between the two study groups, with the CDKN1A 70T allele being less prevalent among cases. Moreover, the double heterozygote genotype combination 31CA-70CT decreases the chance of developing high-grade squamous intraepithelial lesion (HSIL) and cancer (OR = 0.55; 95 % CI = 0.32-0.93; p = 0.034) by 50 %, representing a protective factor against the development of more severe cervical lesions.

Abstract
Cervical cancer is a common malignancy which poses a significant health burden among women, especially those living in the developing countries. Although human papillomavirus (HPV) infection has been unequivocally implicated in the etiopathogenesis of the cancer, it alone is not adequate to contribute to the malignant transformation of cervical cells. Most HPV infections regress spontaneously, and only a small proportion of women have persistent infections which eventually lead to malignancy. This suggests that interplays between HPV infection and other cofactors certainly exist during the process of cervical carcinogenesis, which synergistically contribute to the differential susceptibility of an individual to the malignancy. Undoubtedly, host genetic factors represent a major element involved in such a synergistic interaction, and accumulating evidence suggests that polymorphisms in apoptosis-related genes play an important role in the genetic susceptibility to cervical cancer. This review consolidates the recent literatures on the role of common polymorphisms in apoptosis-related genes in genetic susceptibility to cervical cancer.

Abstract
BACKGROUND In prostate cancer, mutated p53 alleles typically contain missense single-base substitution in codon 72 that resides within exons 5-8. Stable p53 proteins in tumor cell nuclei have been associated with malignancy. A role of p53 is the regulation of drug transporters like ABCC1 (MRP1) by an effect on promoter region. OBJECTIVES The objective of this study was to identify association of mutations of p53 at codon 72 and 282 and promoter region of ABCC1 with increased risks of prostate cancer. MATERIALS AND METHODS Formalin fixed, paraffin-embedded malignant tissues of 45 patients and 45 control samples were evaluated. PCR-RFLP using BstUI for codon 72 and HpaII restriction enzyme for codon 282 p53 gene, and G-1666A promoter region of ABCC1 gene was performed. To assess the frequency of these mutations and to detect new mutations in cancerous samples, PCR-SSCP analysis was performed. RESULTS The frequencies of CC, GC and GG genotypes of codon 72 of p53 were 33.33%, 46.67% and 20.00% in patients with cancer and 15.56%, 48.89% and 35.55% in controls, respectively. The relative allele frequencies of ABCC1 promoter polymorphism were 60.00% A and 40.00% G in patients as opposed to 37.78% for A and 62.22% for G in controls. Genotypic frequencies of p53 codon 72 and G1666A of ABCC1 in patients vs. Controls were statistically significant(p<0.05). The study of these samples with PCR-SSCP displayed some new banding patterns. CONCLUSIONS The present findings suggest that CC homozygosity in codon 72 of p53 gene and AA genotype in G-1666A of ABCC1 gene may play a role in combination in prostate cancer and increased susceptibility for this malignancy in the Iranian Kurdish population.

Abstract
The objective of this study was to identify whether the miR-502-binding site single nucleotide polymorphism (SNP) in the 3'-untranslated region (3'-UTR) of set domain-containing protein 8 (SET8) and the tumor protein p53 (TP53) codon 72 polymorphism were associated with the risk for non-small cell lung cancer (NSCLC), either independently or jointly, among Chinese people from southern Han. The genotypes of SET8 and TP53 codon 72 polymorphisms of peripheral blood DNA were detected using polymerase chain reaction-restriction fragment length polymorphism and direct DNA sequencing in a case-control study on 164 NSCLC cases and 199 controls. The SET8 TT (odds ratio, OR = 2.173, 95% confidence interval, CI = 1.0454.517) or TP53 GG (OR = 2.579, 95% CI = 1.366-4.870) genotype was associated with an increased risk of NSCLC by comparing with the SET8 CC or TP53 CC genotype, respectively. Similar results were obtained in SET8 recessive model (OR = 2.074, 95% CI = 1.019-4.221, P < 0.05), and the dominant and recessive model of TP53 codon 72 were performed, respectively (OR = 1.809, 95% CI = 1.159-2.825, P < 0.05; OR = 1.933, 95% CI = 1.096-3.409, P < 0.05). In addition, interaction between the SET8 and TP53 polymorphisms increased the risk of NSCLC in a multiply manner, with the OR being 3.032 (95%CI = 1.580-5.816) for subjects carrying both SET8 TT and TP53 GG genotypes. Therefore, the miR-502-binding site SNP in the 3'-UTR of SET8 and the TP53 codon 72 polymorphism may be markers of genetic susceptibility to NSCLC in Chinese population, and there is a possible gene-gene interaction in the incidence of NSCLC.

Abstract
Though many studies were published to assess the relationship between p21 Ser31Arg polymorphism and cervical cancer, there was no definite conclusion on this association. To provide a quantitative assessment of the relationship between p21 Ser31Arg polymorphism and cervical cancer, we performed a meta-analysis of 10 eligible studies (1,539 cases and 2,161 controls). All those 10 studies were from Asians. The odds ratios (OR) with 95% confidence intervals (95%CIs) were used to assess the strength of the association, and the pooled ORs were calculated for the codominant model (ArgArg vs. SerSer), the dominant model (ArgArg/SerArg vs. SerSer), and the recessive model (ArgArg vs. SerSer/SerArg). Meta-analysis of those 10 studies showed that there was no association between p21 Ser31Arg polymorphism and cervical cancer risk in Asians under all three models (ArgArg vs. SerSer: OR = 1.04, 95%CI 0.66-1.65, P = 0.86, I(2) = 78%; ArgArg/SerArg vs. SerSer: OR = 0.93, 95%CI 0.66-1.30, P = 0.66, I(2) = 81%; ArgArg vs. SerSer/SerArg: OR = 1.20, 95%CI 0.84-1.73, P = 0.32, I(2) = 72%). Sensitivity analysis performed by omitting each study in turn showed that the pooled results were stable. In summary, there is no association between p21 Ser31Arg polymorphism and cervical cancer risk in Asians. Further studies are needed to assess the possible association between p21 Ser31Arg polymorphism and cervical cancer risk in Caucasians.

Abstract
Background The p21 codon 31 single nucleotide polymorphism (SNP), rs1801270, has been linked to cervical cancer but with controversial results. The aims of this study were to investigate the role of p21 SNP-rs1801270 and other untested p21 SNPs in the risk of cervical cancer in a Chinese population. Methods We genotyped five p21 SNPs (rs762623, rs2395655, rs1801270, rs3176352, and rs1059234) using peripheral blood DNA from 393 cervical cancer patients and 434 controls. Results The frequency of the rs1801270 A allele in patients (0.421) was significantly lower than that in controls (0.494, p = 0.003). The frequency of the rs3176352 C allele in cases (0.319) was significantly lower than that in controls (0.417, p < 0.001).The allele frequency of other three p21 SNPs showed not statistically significantly different between patients and controls. The rs1801270 AA genotype was associated with a decreased risk for the development of cervical cancer (OR = 0.583, 95%CI: 0.399 - 0.853, P = 0.005). We observed that the three p21 SNPs (rs1801270, rs3176352, and rs1059234) was in linkage disequilibrium (LD) and thus haplotype analysis was performed. The AGT haplotype (which includes the rs1801270A allele) was the most frequent haplotype among all subjects, and both homozygosity and heterozygosity for the AGT haplotype provided a protective effect from development of cervical cancer. Conclusions We show an association between the p21 SNP rs1801270A allele and a decreased risk for cervical cancer in a population of Chinese women. The AGT haplotype formed by three p21 SNPs in LD (rs1801270, rs3176352 and rs1059234) also provided a protective effect in development of cervical cancer in this population.

Abstract
BACKGROUND The P53 tumor suppressor gene plays a pivotal role in maintaining cellular homeostasis by preventing the propagation of genome mutations. P53 in its transcriptionally active form is capable of activating distinct target genes that contribute to either apoptosis or growth arrest, like P21. However, the MDM2 gene is a major negative regulator of P53. Single nucleotide polymorphisms (SNP) in codon Arg72Pro of P53 results in impairment of the tumor suppressor activity of the gene. A similar effect is caused by a SNP in codon 31 of P21. In contrast, a SNP in position 309 of MDM2 results in increased expression due to substitution of thymine by guanine. All three polymorphisms have been associated with increased risk of tumorigenesis. AIM OF THE STUDY We aimed to study the prevalence of SNPs in the P53 pathway involving the three genes, P53, P21 and MDM2, among acute myeloid leukemia (AML) patients and to compare it to apparently normal healthy controls for assessment of impact on risk. RESULTS We found that the P21 ser31arg heterozygous polymorphism increases the risk of AML (P value=0.017, OR=2.946, 95% CI=1.216-7.134). Although the MDM2 309G allele was itself without affect, it showed a synergistic effect with P21 ser/arg polymorphism (P value=0.003, OR= 6.807, 95% CI= 1.909-24.629). However, the MDM2 309T allele abolish risk effect of the P21 polymorphic allele (P value= 0.71). There is no significant association of P53 arg72pro polymorphism on the risk of AML. CONCLUSION We suggest that SNPs in the P53 pathway, especially the P21 ser31arg polymorphism and combined polymorphisms especially the P21/ MDM2 might be genetic susceptibility factors in the pathogenesis of AML.

Abstract
Cervical cancer is the second most common cancer in females worldwide. It is well-established that Human Papillomavirus (HPV) infections play a critical role in the development of cervical cancer. However, a large number of women infected with oncogenic HPV types will never develop cervical cancer. Thus, there are several external environment and genetic factors involved in the progression of a precancerous lesion to invasive cancer. In this review article, we addressed possible susceptible phenotypes to cervical cancer, focusing on host genome and HPV DNA variability, multiple HPV infections, co-infection with other agents, circulating HPV DNA and lifestyle.

Abstract
Mitogen-activated protein kinase kinase 4 (MKK4) is a critical mediator of stress-activated protein kinase signals that regulate apoptosis, inflammations, and tumorigenesis. Several polymorphisms have been identified in the MKK4 gene. We hypothesized that genetic variants in the MKK4 promoter may alter its functions and thus cancer risk. In the current, hospital-based case-control study of 471 cervical cancer cases and 600 sex and age frequency-matched cancer-free controls in an Eastern Chinese population, we genotyped two common polymorphisms in the MKK4 promoter region (-1304T>G, rs3826392 and -1044A>T, rs3809728)c and assessed their associations with the risk of cervical cancer. We found that compared with the most common -1304TT genotype, carriers of -1304G variant genotypes had a significantly decreased risk of cervical cancer [odds ratio (OR) = 0.71; 95% confidence interval (CI) = 0.53-0.92 for TG, and OR = 0.52; 95%CI = 0.30-0.91 for GG] in an allele dose-response manner (adjusted P(trend) = 0.004). Moreover, the luciferase assay showed that the G allele in the promoter significantly increased the transcription activity of the MKK4 gene in vitro and that the MKK4 mRNA expression levels of the G variant carriers was significantly higher in tumor tissues than those of the -1304TT genotype. However, no significant association was observed between the -1044A>T polymorphism and risk of cervical cancer. Our data suggest that the functional -1304G variant in the MKK4 promoter contributes to a decreased risk of cervical cancer by increasing the promoter activity and that the G variant may be a marker for susceptibility to cervical cancer.

Abstract
Platelet-derived growth factor (PDGF)-BB can induce abnormal proliferation and migration of vascular smooth muscle cells (VSMC) that are involved in the development of CVD. In our preliminary study, phytoalexin glyceollins (glyceollins I, II and III) isolated from soyabean seeds cultured withAspergillus sojaeshowed strong antioxidant and anti-inflammatory activity. Since antioxidants showed beneficial effects on chronic inflammatory diseases, the purpose of the present study was to examine the effects of glyceollins on PDGF-induced proliferation and migration in human aortic smooth muscle cells (HASMC). Incubation of resting HASMC with glyceollins for 24 h significantly diminished PDGF-increased cell number and DNA synthesis in a dose-dependent manner without any cytotoxicity. In addition to blocking of the PDGF-inducible progression through the G0/G1to the S phase of the cell cycle, glyceollins down-regulated the expression of cyclin-dependent kinase (CDK)2 and cyclin D1, and up-regulated the expression of CDK inhibitors such as p27kip1and p53.Glyceollins also effectively inhibited reactive oxygen species generation and phosphorylation of PDGF receptor-β, phospholipase Cγ1, Akt and extracellular signal-regulated kinase 1/2 by PDGF stimulation. Furthermore, glyceollins were found to inhibit PDGF-induced dissociation of actin filaments and cell migration. Thus, the results suggest that glyceollins could become a potent therapeutic agent for regulating VSMC-associated vascular disease such as atherosclerosis and restenosis after angioplasty.

Abstract
BackgroundStudies investigating the association between p21 genetic polymorphism Ser31Arg and cervical cancer (CC) risk report conflicting results. The aim of this study was to quantitatively summarize the evidence for p21 polymorphism and CC risk.MethodsTwo investigators independently searched the MEDLINE, Embase, CNKI, and Chinese Biomedicine databases. Summary odds ratios (ORs) and 95% confidence intervals (CIs) for p21 polymorphism and CC were calculated in a fixed effects model (the Mantel-Haenszel method) and a random effects model (the DerSimonian and Laird method) when appropriate. The pooled ORs were performed for codominant model (Arg/Arg vs Ser/Ser and Arg/Ser vs Ser/Ser), dominant model (Arg/Arg + Arg/Ser vs Ser/Ser), and recessive model (Arg/Arg vs Arg/Ser + Ser/Ser). Subgroup analyses were performed by country, matched controls, and Hardy-Weinberg equilibrium in the controls and study sample size.ResultsThis meta-analysis included 10 case-control studies from an Asian population, which included 1415 CC cases and 1947 controls. Overall, the variant genotypes (Arg/Arg and Arg/Ser) of Ser31Arg were not associated with CC risk, when compared with the wild-type homozygote Ser/Ser (Arg/Arg vs Ser/Ser: OR, 1.30; 95% CI, 0.81-2.08; Arg/Ser vs Ser/Ser: OR, 1.06; 95% CI, 0.72-1.55). Similarly, no associations were found in the dominant and recessive models (dominant model: OR, 1.05; 95% CI, 0.73-1.51; recessive model: OR, 1.28; 95% CI, 0.86-1.90). Stratified analyses also detected no significant association in any subgroup, except among those studies from "other" country and those studies with controls deviated from Hardy-Weinberg equilibrium.ConclusionNo association was found between the p21 polymorphism Arg31Ser and risk of CC among Asians. In the future, additional studies based on white and African American patients should be performed to re-evaluate the association.
