Parida S, Siddharth S, Xia Y, Sharma D. Concomitant analyses of intratumoral microbiota and genomic features reveal distinct racial differences in breast cancer. NPJ Breast Cancer 2023; 9:4.

Abstract
Racial disparities are most accentuated among Black women as their lifetime risk of breast cancer incidence is lower than white and Asian women but their breast cancer related mortality is the highest among all races. Black women are more likely to develop triple-negative breast cancer at a younger age and harbor more aggressive tumors. In addition to tumor-centric alterations, tumor growth is also influenced by multiple other tumor microenvironment-related features, including resident immune cells and microbiota. Hence, in this study, we conduct concurrent genomic and metagenomic analyses, and uncover distinctive intratumoral microbial community compositions and tumor immune microenvironment-related traits in breast tumors from Asian, Black and white women. Interestingly, unique racially associated genomic nodes are found in the breast tumors from Asian, Black and white women. Examination of the cellular heterogeneity show differential enrichment of 11 out of 64 immune and stroma cell types in the breast tumors from different racial groups. In terms of microbial diversity, significant differences are revealed in alpha and beta-diversity measures. Intriguingly, potential race-specific microbial biomarkers of breast cancer are identified which significantly correlate with genes involved with tumor aggressiveness, angiogenesis, tumor cell migration and metastasis as well as oncogenic pathways-GLI and Notch. Investigating the metabolic features of intratumoral microbes, we find a significant differential enrichment of environmental information processing pathways, oncogenic pathways, and lipid metabolism pathways. Concomitantly investigating tumor-centric, tumor immune microenvironment-related and microbial alterations, our study provides a comprehensive understanding of racial disparities in breast cancer and warrants further exploration.

Das AP, Saini S, Agarwal SM. A comprehensive meta-analysis of non-coding polymorphisms associated with precancerous lesions and cervical cancer. Genomics 2022; 114:110323. [PMID: 35227837 DOI: 10.1016/j.ygeno.2022.110323] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 02/15/2022] [Accepted: 02/22/2022] [Indexed: 01/14/2023]
Abstract
OBJECTIVES To study the risk of polymorphisms present in the non-coding regions of genes related with cervical cancer. METHODS The PubMed database was extensively searched using text-mining techniques to identify literature containing the association of single nucleotide polymorphisms and cervical cancer. Case-control studies published till June 2020 were considered for the meta-analysis if they fulfilled the selection criteria. The polymorphisms within each case-control study were checked for the presence of genotype data and then divided into groups based on the precancerous and cancerous conditions of the cervix. Odds ratio and 95% confidence intervals (CI) were used to study the effects of polymorphisms with the help of different genetic models (allele, dominant, recessive, heterozygous and homozygous). Also checked heterogeneity along with publication bias and statistical significance using the p-value. RESULTS 120 papers covering 48 unique non-coding SNPs having 37,123 cases and 39,641 control data was considered for the meta-analysis. The genotype data was categorised into Cancer, Precancer and "Cancer + Precancer" groups, for 43, 8 and 11 SNPs respectively. The meta-analysis identified 21 and 1 SNPs as significant in the Cancer and "Cancer + Precancer" groups. Among all the polymorphisms, rs1143627 (IL1B), rs1800795 (IL6), rs1800871 (IL10), rs568408 (IL12A), rs3312227 (IL12B), rs2275913 (IL17A), rs5742909 (CTLA4), rs1800629 (TNFα), and rs4646903 (CYP1A1) were found to increase risk of cervical cancer in at least three of the five genetic models. CONCLUSION We identified potential non-coding SNPs corresponding to various cytokines like interleukins (ILs), tumor necrosis factor (TNF), interferon (IFN) and other immune related genes like toll like receptor (TLR), cytotoxic T-lymphocyte associated protein (CTLA) and matrix metalloproteinase (MMP), as significant with increased pooled OR in this meta-analysis pointing to risk association of the immune-related genes in cervical carcinogenesis.

Microrna 2022; 10:219-224. [PMID: 34989332 DOI: 10.2174/2211536610666210715102554] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 05/25/2021] [Accepted: 06/01/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The prevalence of Cervical Cancer (CC) is disproportionately higher in developing countries. It is the second most frequent cancer type among Bangladeshi women and the major cause of morbidity and mortality. However, no previous data reported the association of miR-218-2 gene polymorphisms in Bangladeshi cervical cancer patients. AIM This case-control study was designed to find the link between the rs11134527 polymorphism in miR-218-2 and CC. METHODS A total of 488 subjects were recruited, comprising 256 cervical cancer patients and 232 healthy females. Genotyping was conducted with the tetra-primer ARMS-PCR technique to detect the association. RESULTS The results of genotype data showed that rs11134527 was in the Hardy-Weinberg equilibrium in both CC cases and controls (P >0.05). Overall, the polymorphism was found to be significantly associated with an increased risk of cervical cancer with AG genotype (AG vs. GG: OR = 2.26, 95% Cl = 1.40-3.66, P = 0.0008), AA genotype (AA vs. GG: OR = 3.64, 95% Cl = 2.17-6.10, P <0.0001), dominant model (AG+AA vs. GG: OR = 2.75, 95% Cl = 1.75-4.31, P <0.0001), recessive model (AA vs. GG+AG: OR = 2.08, 95% Cl = 1.41-3.08, P = 0.0002), and A allele (A vs. G: OR = 1.94, 95% Cl = 1.51-2.51, P <0.0001). All of these correlations remained statistically significant after performing Bonferroni correction (P <0.008). CONCLUSION Our study suggests that the rs11134527 polymorphism in the miR-218-2 gene contributes to the susceptibility of CC in Bangladeshi women.

Abstract
BACKGROUND We investigated the correlation between a history of human papillomavirus (HPV) infection and alopecia areata risk. METHODS The study cohort comprised 30,001 patients with newly diagnosed HPV infection between 2000 and 2012; and with use of computer-generated randomly numbers, patients not had HPV infection were randomly selected as the comparison cohort. HPV infection cohort were matched to comparison individuals at a 1:1 ratio by age, gender and index year. All study individuals were followed up until they developed alopecia areata, withdraw from the insurance program, lost to follow-up, or until the end of 2013. Cox proportional hazards regression analysis was used to analyze the risk of alopecia areata with hazard ratios (HRs) and 95% confidence intervals (CIs) between the HPV and control cohort. RESULTS The adjusted hazard ratio (aHR) of alopecia areata for HPV patients relative to controls was 2.55 (95% C.I. = 1.88-3.47) after adjusting sex, age and comorbidities. Subgroup analysis indicated that patients with HPV infections had a significantly greater risk of alopecia areata for both genders, all age subgroups, and those with mental disorder diseases. CONCLUSIONS A history of HPV infection is associated with the development of subsequent alopecia areata in Taiwanese subjects.

Abstract
Objectives: This study investigated the relationship between single-nucleotide polymorphisms (SNPs) in cytokine genes and the susceptibility to Squamous Intraepithelial Lesions (SIL), cervical cancer and HPV infection through a systematic review with meta-analysis. To verify the effect of SNPs, we also analyzed the transcription factor binding affinity using bioinformatics tools.Methods: Seven electronic databases (MEDLINE, Scielo, BIREME, PubMed, Scopus, Web of Science and Science Direct) were searched for case-control studies.Results: A total of 35 relevant case-control studies were meta-analyzed, including 7 cytokine genes and 15 SNPs. SNPs in IL-17A (rs2275913, rs3748067); IL-17 F (rs763780); IL-12A (rs568408); IL-12B (rs3212227); TNFA (rs1800629, rs361525); IL-1B (rs16944); IL-6 (rs1800795); IL-10 (rs1800896) genes were associated with increased risk for cervical cancer. No association was observed between meta-analyzed polymorphisms and SIL. Additional bioinformatics analysis suggested a possible transcriptional regulation pathway of the TNFA and IL-10 genes through the MZF1 (TNFA -308 G > A and IL-10 - 1082A>G) and ZNF263 (TNFA -238 G > A) transcription factors binding.Conclusion: Overall, 10 SNPs in cytokine genes were associated with increased risk for cervical cancer. Therefore, in our meta-analysis, these SNPs demonstrated to be potential biomarkers for predicting or identifying cases of high risk for SIL and cervical cancer.

Abstract
BACKGROUND Cancer is the single leading cause of human deaths worldwide. The highest incidence and mortality are recorded from Africa. The last two decades have witnessed extensive research which has led to emerging prognosis and new gene therapy technologies. Cancer therapy in Africa is derived with little input from African population data. While a number of cancer studies on African populations have suggested varied susceptible variant, no comprehensive review of these studies has been undertaken to assess their coverage across Africa. METHODS This study aimed to undertake a review of all molecular genetic studies that interrogated the genetic variants of cancers in African-based populations. Our search methodology was modelled after the Cochrane systematic review protocol, which included MeSH terms and related keywords. RESULTS Ninety-seven articles studying 13 cancer types, were reviewed. 91 articles screened for polymorphisms using PCR-based techniques while three used SNP array, two used whole exome sequencing and one used pyrosequencing. North African (NA) countries undertook 51/97 (53 %) studies on 12/13 (92 %) cancer types while the Sub Saharan Africa (SSA) countries undertook 46/97 (47 %) studies on 7/13 (54 %) cancer types. Twelve out of these thirteen cancer type studies suggested susceptibility to their target polymorphism (p > 0.05). No study replicated or validated variants detected. CONCLUSION Research on genetic determinants in African-based population cancer offers translational benefits. We recommended large scale, multi-national genome association studies using high throughput techniques. SSA needs to receive more attention due to the shortage of this type of study and data in the region.

Abstract
Prostate cancer affects African Americans disproportionately by exhibiting greater incidence, rapid disease progression, and higher mortality when compared to their Caucasian counterparts. Additionally, standard treatment interventions do not achieve similar outcome in African Americans compared to Caucasian Americans, indicating differences in host factors contributing to racial disparity. African Americans have allelic variants and hyper-expression of genes that often lead to an immunosuppressive tumor microenvironment, possibly contributing to more aggressive tumors and poorer disease and therapeutic outcomes than Caucasians. In this review, we have discussed race-specific differences in external factors impacting internal milieu, which modify immunological topography as well as contribute to disparity in prostate cancer.

Abstract
Human papillomavirus (HPV) is an essential but not a sufficient cervical cancer etiological factor. Cancer promoters, such as host genetic mutations, significantly modulate therapeutic responses and susceptibility. In cervical cancer, of interest have been viral clearing genes and HPV oncoprotein targets, for which conflicting data have been reported among different populations. This expert analysis evaluates cervical cancer genetic susceptibility biomarkers studied in African populations. Notably, the past decade has seen Africa as a hotbed of biomarker and precision medicine innovations, thus potentially informing worldwide biomarker development strategies. We conducted a critical literature search in PubMed/MEDLINE, Google Scholar, and Scopus databases for case-control studies reporting on cervical cancer genetic polymorphisms among Africans. We found that seven African countries conducted cervical cancer molecular epidemiology studies in one of Casp8, p53, CCR2, FASL, HLA, IL10, TGF-beta, and TNF-alpha genes. This analysis reveals a remarkable gap in cervical cancer molecular epidemiology among Africans, whereas cervical cancer continues to disproportionately have an impact on African populations. Genome-wide association, whole exome- and whole-genome sequencing studies confirmed the contribution of candidate genes in cervical cancer. With such advances and omics technologies, the role of genetic susceptibility biomarkers can be exploited to develop novel interventions to improve current screening, diagnostic and prognostic methods worldwide. Exploring these genetic variations is crucial because African populations are genetically diverse and some variants or their combined effects are yet to be discovered and translated into tangible clinical applications. Thus, translational medicine and flourishing system sciences in Africa warrant further emphasis in the coming decade.

Abstract
Previous studies have suggested that interleukin-10 (IL-10) polymorphisms may be associated with an increased risk of developing cervical cancer. However, the published results on this subject matter are controversial. The aim of this study was to conduct a meta-analysis of published reports to more precisely investigate the relationship between IL-10 polymorphisms and cervical cancer risk. Five online databases (PubMed, Embase, Web of SCI, CNKI and Wanfang) were searched, and seventeen articles with sufficient quantitative information were included in our meta-analysis. The odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between IL-10 polymorphisms and cervical cancer risk. Publication bias, sensitivity and cumulative analyses were also performed to support our findings. Overall, there was a significant association between the IL-10 -1082A > G polymorphism and cervical cancer risk observed in the total population (G vs. A: OR = 1.60, 95% CI = 1.12–2.29, P = 0.01, I2 = 92.3%; AG vs. AA: OR = 1.34, 95% CI = 1.04-1.74, P = 0.03, I2 = 65.9%; AG + GG vs. AA: OR = 1.58, 95% CI = 1.11–2.25, P = 0.01, I2 = 84.4%), and the same results were obtained in the subgroup analysis. Moreover, the IL-10 -819 T > C polymorphism exhibited a significant, protective effect against cervical cancer. In summary, our meta-analysis suggests that IL-10 polymorphisms may play a variety of roles in regard to cervical cancer risk, especially in Asians.

Abstract
We read with great interest the paper entitled "Interferon gamma +874 T/A polymorphism increases the risk of cervical cancer: evidence from a meta-analysis" published online by Sun et al. Their results suggest that interferon gamma ( IFNG) gene +874 T/A polymorphism might contribute to women's susceptibility to cervical cancer. They also found that IFNG +874 T/A polymorphism is associated with increased cervical cancer risk in Asian female population. The result is encouraging. Nevertheless, several key issues are worth noticing. We re-evaluate the association between IFNG +874 T/A polymorphism and cervical cancer risk by performing an updated meta-analysis based on 2777 cases and 2542 controls of 11 studies. We found that IFNG +874 T/A polymorphism was not significantly associated with cervical cancer risk in overall population. We also observed that the polymorphism was associated with enhanced cervical cancer risk in Asian population and was relevant to increased squamous cell cervical cancer risk.

Abstract
Last few decades have witnessed remarkable progress in our understanding of cancer initiation and progression leading to refinement of prevention and treatment approaches. Although these advances have improved the survival of cancer patients in general, certain racial/ethnic groups have benefited only partially. Footprints of cancer-associated racial disparities are very much evident in cancers of the prostate, breast, cervical, colorectal, endometrium, liver and lung. These health inequalities are mostly attributed to socioeconomic differences among races, but there is a growing realization that these may actually be due to inherent biological differences as well. Indeed, significant data now exist to support the biological basis of racial disparities in cancer, warranting basic research investigations, using appropriate tools and model systems. In this article, we have aimed to succinctly review the literature supporting the biological bases of racial disparities in cancer, along with available resources, databases and model systems that will be of interest to researchers. Moreover, we have highlighted the specific areas that need attention in terms of development of resources and/or tools, and discuss the opportunities and challenges in basic biological research in cancer health disparities.

Abstract
Recent studies have showed interleukin 10 (IL-10) is a critical cytokine that determines antiviral immune response and is related to virus-associated cancers. However, whether genetically elevated circulating IL-10 levels are associated with the risk of human papilloma virus and Epstein–Barr virus-associated cancers (HEACs) is still unclear. Mendelian randomization method was implemented to meta-analyze available observational studies by employing IL-10 three variants (−592C>A, −819C>T, and −1082A>G) as instruments. A total of 24 articles encompassing 11,170 subjects were ultimately eligible for the meta-analysis. Overall, there was a significant association between IL-10 promoter variant −1082A>G and HEACs under allelic and dominant models (both P<0.01). Subgroup analysis by cancer type indicated that the risk estimate of −1082A>G was significant for nasopharyngeal cancer under allelic, homozygous genotypic and dominant models (all P<0.001). Moreover by ethnicity, carriers of −1082G allele had a 74% increased risk for nasopharyngeal cancer in Asians under dominant model (odds ratio [OR] =1.737; 95% confidence interval [CI]: 1.280–2.358; P<0.001). In further Mendelian randomization analysis, the predicted OR for 10 pg/mL increment in IL-10 levels was 1.14 (95% CI: 1.01–16.99) in HEACs. Our findings provided strong evidence for a critical role of genetically elevated circulating IL-10 levels in the development of HEACs, especially in Asian population and for nasopharyngeal cancer.

IL-10 gene promoter and intron polymorphisms as genetic biomarkers of cervical cancer susceptibility among Tunisians. Cytokine 2015; 76:343-347. [PMID: 26076679 DOI: 10.1016/j.cyto.2015.05.028] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Revised: 05/27/2015] [Accepted: 05/31/2015] [Indexed: 12/31/2022]
Abstract
OBJECTIVE We investigated the association between polymorphisms in the promoter and intron regions of the interleukin-10 (IL-10) gene with the risk of cervical cancer (CC) in Tunisian patients and control women. METHODS Study subjects comprised 86 CC cases and 126 control women. Genotyping of IL-10 intron (rs3024491, rs3024490) and promoter (rs1800872, rs1800871, rs1800896) variants was done by real-time PCR, with defined clusters. RESULTS The minor allele frequencies of the five tested IL-10 SNPs were not significantly different between cervical cancer cases and control women. However, significantly higher frequencies of homozygous minor allele-carriers in cases was seen for rs3024490 (P=0.023), rs1800872 (P=0.037), and rs1800871 (P=0.028). IL-10 serum levels were significantly reduced in rs3024490 T/T vs. G/G genotype carriers, and in rs1800871 T/T than C/C genotype carriers. While carriage of rs1800872 and rs3024491 minor allele was associated with reduced IL-10 secretion, this was not statistically significant. Haploview analysis demonstrated high linkage disequilibrium (LD) among the IL10 SNPs studied, and only seven haplotypes were common, capturing 98.8% of the total possible haplotypes. Reduced frequency of haplotypes GTCCA (P<0.001) and TGATG (P<0.001) was seen in cervical cancer cases than in control women, thus conferring disease protection nature to these haplotype. This association remained significant for GTCCA (Pc=0.006) and TGATG (P=0.045) after correcting for multiple comparisons. CONCLUSION Specific IL-10 variants (rs3024490, rs1800872, and rs1800871) and haplotype (GTCCA and TGATG) may contribute to the development of cervical cancer among Tunisian women.

Abstract
OBJECTIVE Interferon-γ (IFN-γ) and signal transducers and activators of transcription (STATs) each play an important role in carcinogenesis associated with viral infection. Cervical cancer is almost invariably associated with infection by human papillomavirus (HPV), and previous studies suggested that dysregulation of the signal pathway involved in IFN-γ and STATs is associated. Our objective was to evaluate the association of SNPs in STAT2, STAT3, and IFN-γ with cervical cancer susceptibility in Chinese Han women in Hunan province. MATERIALS AND METHODS Genomic DNA was extracted from peripheral blood samples of 234 cervical cancer patients and 216 healthy female controls. STAT2 and STAT3 genotyping was performed using polymerase chain reaction-restriction enzyme (PCR-RE) analysis. IFN-γ genotyping was detected by PCR-amplification of specific allele (PASA). RESULTS For STAT2 rs2066807 polymorphisms, there was no significant difference of genotype distribution (P=0.827) and allele frequencies (P=0.830, OR=1.09, 95% CI: 0.51-2.31) between cases and controls. For STAT3 rs957970 polymorphisms, there was no significant difference of genotype distribution (P=0.455) and allele frequencies (P=0.560, OR=0.92, 95% CI: 0.71-1.20) between cases and controls. For IFN-γ +874A/T polymorphisms, there was no significant difference of genotype distribution (P=0.652) and allele frequencies (P=0.527, OR=1.12, 95% CI: 0.79-1.59) between cases and controls. CONCLUSION These results suggest that polymorphisms in STAT2, STAT3 and IFN-γ genes are not likely to be strong predictors of cervical cancer in Han women in southern China.

Abstract
Interferon gamma (IFN-γ) is a potent proinflammatory cytokine which plays an important role in the antiviral, antiproliferative, and antitumor activities. So our meta-analysis was conducted to evaluate the correlations between common genetic polymorphisms in the IFN-γ gene and susceptibility to cervical cancer. The +874 polymorphism in IFN gene region reportedly affects cancer risk. In order to derive a more precise estimation of the association, eight clinical case-control studies met all the inclusion criteria and were included in this meta-analysis. A total of 2,375 cancer cases and 2,106 controls were involved in this meta-analysis. Overall, no significant association was detected in allelic model (A allele vs. T allele OR=0.97, 95% CI, 0.73~1.28), homozygote comparison (AA vs. TT OR=1.12, 95% CI, 0.68~1.85), heterozygote comparison (AT vs. TT OR=1.43, 95% CI, 0.97~1.61), dominant model (AA+AT vs. TT OR=1.19, 95% CI, 0.87~1.63), nor recessive model (AA vs. AT+TT OR=0.95, 95% CI, 0.64~1.40). Subgroup analysis based on ethnicity, genotyping method, and Hardy-Weinberg equilibrium status. Ethnicity suggested that genetic polymorphisms in the IFN-γ gene were closely correlated with increased cervical cancer risk among Asians (allele model: OR=1.11, 95% CI=0.61~2.02, P<0.001; recessive model: OR=0.98, 95% CI=0.36~2.96, P<0.001; homozygous model: OR=1.43, 95% CI=0.56~3.65, P=0.001; respectively), but not among Mixed (all P>0.05). In conclusion, the current meta-analysis supported that IFN-γ genetic polymorphism may contribute to cervical cancer susceptibility, and further well-designed studies with large sample size are warranted to validate our conclusion.

Abstract
Data from previous studies about the association between interferon gamma (IFN-γ) +874 T/A (rs2430561) polymorphism and cervical cancer risk offer controversial results. To obtain a more dependable conclusion, this meta-analysis was performed. We selected eight articles including nine case-control studies with 1,116 cases and 1,290 controls, odds ratios (OR) with 95 % confidence intervals (CI) were used to assess the strength of the association. Subgroup analysis was carried out by ethnicity, source of controls, genotyping methods, and score of quality assessment. Our meta-analysis indicated that the IFN-γ (+874 T/A) polymorphism significantly increased the risk of cervical cancer in the codominant model (TA vs. TT: OR = 1.471, 95 % CI = 1.137-1.903, P = 0.003, I (2) % = 0.0, P Q = 0.785) and the dominant model (TA + AA vs. TT: OR = 1.399, 95 % CI = 1.097-1.784, P = 0.007, I (2) % = 0.0, P Q = 0.486) in the overall population. Stratified analysis by ethnicity indicated a significantly increased risk of cervical cancer in Asians in the codominant model (TA vs. TT: OR = 1.494, 95 % CI = 1.069-2.087, P = 0.019, I (2) % = 0.0, P Q = 0.440) and the dominant model (OR = 1.455, 95 % CI = 1.062-1.993, P = 0.019, I (2) % = 42.9, P Q = 0.154). Thus, the IFN-γ (+874 T/A) polymorphism is likely to increase the risk of cervical cancer. Because of the limited studies and sample sizes included in our meta-analysis, further well-designed and large-scale studies are demanded to confirm our results.

Abstract
PURPOSE/OBJECTIVES To examine racial differences in inflammatory cytokine levels (interleukin [IL]-6 and interferon-gamma [IFN-γ]) and breast cancer (BC) risk factors between healthy Caucasian and African American women; to examine differences in relationships of inflammatory cytokine levels with BC risk factors between these groups of women; and to determine the independent contribution of race to IL-6 and IFN-γ after controlling for relevant covariates. DESIGN Cross-sectional and correlational descriptive design. SETTING Community surrounding a state university health system in the southeastern United States. SAMPLE 113 healthy women (65 Caucasians and 48 African Americans) aged 20 years or older and not pregnant. METHODS Secondary analysis of data collected from self-report questionnaires and blood samples. MAIN RESEARCH VARIABLES Inflammatory cytokine levels, BC risk factors (age, age at menarche, age at first live birth, family history of BC, breast biopsy, breastfeeding history and duration, body mass index, and physical activity), and race. FINDINGS Significant racial differences were noted in IL-6 and IFN-γ levels, reproductive or hormonal and lifestyle BC risk factors, and relationships between African American and Caucasian women. Controlling for all other effects, race appeared to be a significant predictor for IL-6 and IFN-γ. CONCLUSIONS Racial differences in inflammatory cytokines and BC risk factors may provide partial evidence for existing racial disparities in BC for African American and Caucasian women. Additional studies are needed to confirm that potential. IMPLICATIONS FOR NURSING Additional biobehavioral research in racial disparities in BC may help to inform nurses to target race-specific modifications of lifestyle and behavioral factors to reduce BC health disparity between African American and Caucasian women. KNOWLEDGE TRANSLATION Being an African American woman predicted a higher level of inflammatory cytokine production after controlling for selected BC risk factors. Great potential exists for inflammatory responses as one of the underlying biologic mechanisms for existing BC disparity and for culturally tailored lifestyle or behavioral modification interventions for reducing BC risk and racial disparity.

Abstract
Interferon gamma (IFN-γ) is a potent proinflammatory cytokine which plays a pivotal role in the antiviral, antiproliferative, and antitumor activities. A T-to-A transition at the position +874 of human IFN-γ gene (IFNG) has been reported to influence the secretion of IFN-γ and affect cancer susceptibility. However, results from published studies on the association between IFNG +874 T/A polymorphism and cancer risk are inconclusive or even controversial. In order to derive a more precise estimation of the association, a meta-analysis of 38 eligible studies including 5,630 cases and 6,096 controls was conducted with odds ratio (OR) and its corresponding 95 % confidence interval (95 % CI). Overall, no significant association was detected in allelic model (A allele vs. T allele-OR = 0.96, 95 % CI, 0.86-1.08), homozygote comparison (AA vs. TT-OR = 0.97, 95 % CI, 0.79-1.21), heterozygote comparison (AT vs. TT-OR = 1.03, 95 % CI, 0.87-1.23), dominant model (AA + AT vs. TT-OR = 1.00, 95 % CI, 0.87-1.15), nor recessive model (AA vs. AT + TT-OR = 0.93, 95 % CI, 0.78-1.12). Further subgroup analyses based on ethnicity, cancer types, and Hardy-Weinberg equilibrium status failed to demonstrate any significant relationship except in African population under recessive model (AA vs. AT + TT-OR = 0.68, 95 % CI, 0.47-0.97). In conclusion, the current meta-analysis suggested that IFNG +874 T/A polymorphism may not contribute to cancer susceptibility, and further well-designed studies with large sample size are warranted to validate our conclusion.

Abstract
Epidemiological and laboratory-based studies have identified infection with one of 15 high-risk human papillomavirus (HPV) types as a necessary but not sufficient cause of cervical cancer. The prevalence of genital HPV infections is high in young women, but most of the infections regress without interventions. Host genetic variations in genes involved in immune response pathways may be related to HPV clearance, and HPV E6/E7 oncoproteins interacting or downstream genes, both coding and non-coding, may contribute to the outcome of high risk HPV infection and cervical cancer. Of specific interest for this review has been the selection of genetic variants in genes involved in the above-referred pathways with a summary of their applications in association studies. Because the supportive and opposing data have been reported in different populations, well-designed international collaborative studies need to be conducted to define the consistency of the associations, paving the way to better define the patients at high risk of developing cervical cancer.

Abstract
BackgroundA debate exists about whether interleukin 10 (IL-10) polymorphisms (IL-10−1082G/A and IL-10−592C/A) confer additional risk for cervical cancer. To derive a more precise estimation of the relationship between IL-10 polymorphisms and cervical cancer risk, we conducted a meta-analysis of all available studies relating the −1082G/A and −592C/A polymorphisms of the IL-10 gene to the risk of developing cervical cancer.MethodsEight studies were eligible for IL-10 −1082G/A (1498 cases and 1608 controls), and 5 studies were eligible for IL-10 −592C/A (2396 cases and 1388 controls). Pooled odds ratios (ORs) were appropriately derived from fixed-effects or random-effects models. Subgroup analyses were performed by ethnicity and Hardy-Weinberg equilibrium in the controls.ResultsIn the overall analysis, no significant association between the IL-10−1082G/A polymorphism and the risk of cervical cancer was observed. In the subgroup analysis by ethnicity, IL-10 −1082A allele was associated with decreased cervical cancer susceptibility among whites (A vs G: OR, 0.39; 95% confidence interval [CI], 0.32–0.47). Studies with controls deviated from Hardy-Weinberg equilibrium showed an evident association in dominant model (GA/AA vs GG: OR, 1.73 [95% CI, 1.04–2.89]). On the other hand, with respect to −592C/A polymorphism, significantly elevated cervical cancer risk was found in the overall analysis (A vs C: OR, 1.16 [95% CI, 1.04–1.31]; AA vs CC: OR, 1.36 [95% CI, 1.00–1.84]; CA/AA vs CC: OR, 1.18 [95% CI, 1.01–1.39]; AA vs CC/CA: OR, 1.25 [95% CI, 1.01–1.55]). Stratified analysis indicated that significantly increased risks were also found among Asians in the allelic model (A vs C: OR, 1.23 [95% CI, 1.01–1.49]).ConclusionsInterleukin 10−1082 G/A polymorphism showed no effect on cervical cancer risk in the overall analysis. The genetic polymorphism in IL-10−592C/A is a risk factor for developing cervical cancer, especially for Asians.

Abstract
PURPOSE Single nucleotide polymorphism (SNP) in IFN-γ gene (+874T/A) that determines high (TT), low (AA), and intermediate (TA) responder phenotypes has shown associations with susceptibility to infectious and chronic inflammatory diseases, as well as disease outcome. Therefore, the susceptibility to and outcome of certain diseases can vary in different ethnic populations partially due to the notable differences in frequencies of genotypes and alleles between them. The aim of this study was to determine the distribution of +874T/A genotype and allele frequencies in a healthy Serbian population as a reference for further disease association studies. MATERIALS AND METHODS Genomic DNA samples from 166 healthy volunteers were evaluated for IFN-γ SNP at position +874 using TaqMan SNP genotyping assay. RESULTS The frequencies of AA, AT, and TT genotypes were 28.9%, 49.4%, and 21.7%, respectively. The A and T allele frequencies were 53.6% and 46.4%. CONCLUSIONS Analysis of genotype and allele frequencies for IFN-γ+874T/A SNP in healthy subjects revealed, for the first time, the genetic profile for this polymorphism in a Serbian population resembling most European populations, but differing from some Asian and African ethnic groups.

Abstract
Cervical cancer is the second most common cancer in women worldwide. This is caused by oncogenic types of human papillomavirus (HPV) infection. Although large numbers of young sexually active women get HPV-infected, only a small fraction develop cervical cancer. This points to different co-factors for regression of HPV infection or progression to cervical cancer. Host genetic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review is to compile the advances in the field of host genetics of cervical cancer. MEDLINE database was searched using the terms, ‘HPV’, ‘cervical’, ‘CIN’, ‘polymorphism(s)’, ‘cervical’+ *the name of the gene* and ‘HPV’+ *the name of the gene*. This review focuses on the major host genes reported to affect the progression to cervical cancer in HPV infected individuals.

Abstract
Genetic variation has long been thought associated with common complex disease and has therefore been widely studied. Genetic variation in the human genome is present in many forms and have been summarised in this review. The potential role of DNA damage, DNA repair and environmental influence on genetic variation in the development of cancer will be discussed, before significant genome projects are reviewed. All the various forms of genetic variation have been associated with malignancies and have been extensively studied and this is a review of the state of the field. We also discuss the road ahead in fulfilling the ultimate goal in all cancer genetic studies, which is decreasing deaths caused by cancer.

Abstract
Human papillomaviruses (HPVs) are one of the most common sexually transmitted infections and remains a public health problem worldwide. There is strong evidence that HPV causes cervical, vulva and vaginal cancers, genital warts and recurrent respiratory papillomatosis. The current treatments for HPV-induced infections are ineffective and recurrence is common-place. Therefore, to reduce the burden of HPV-induced infections, several studies have investigated the effi cacy of different prophylactic vaccines in clinical human trials directed against HPV types 6, 11, 16, or 18. Notably, these HPV types contribute to a signifi cant proportion of disease worldwide. This review will focus on the published results of Merck & Co’s prophylactic quadrivalent recombinant vaccine targeting HPV types 6, 11, 16, and 18 (referred to as Gardasil®). Data from the Phase III trial demonstrated that Gardasil was 100% effi cacious in preventing precancerous lesions of the cervix, vulva, and vagina and effective against genital warts. Due to the success of these human clinical trials, the FDA approved the registration of Gardasil on the 8 June 2006. In addition, since Gardasil has been effi cacious for 5 years post vaccination, the longest evaluation of an HPV vaccine, it is expected to reduce the incidence of these type specifi c HPV-induced diseases in the future.

Abstract
Epidemiological and laboratory-based studies have identified infection with one of 15 high-risk human papillomavirus (HPV) types as a necessary but not sufficient cause of cervical cancer. The prevalence of genital HPV infections is high in young women, but most of the infections regress without interventions. Host genetic variations in genes involved in immune response pathways may be related to HPV clearance, and HPV E6/E7 oncoproteins interacting or downstream genes, both coding and non-coding, may contribute to the outcome of high risk HPV infection and cervical cancer. Of specific interest for this review has been the selection of genetic variants in genes involved in the above-referred pathways with a summary of their applications in association studies. Because the supportive and opposing data have been reported in different populations, well-designed international collaborative studies need to be conducted to define the consistency of the associations, paving the way to better define the patients at high risk of developing cervical cancer.

Abstract
Leprosy is a chronic infectious disease caused by Mycobacterium leprae, a low virulence mycobacterium, and the outcome of disease is dependent on the host genetics for either susceptibility per se or severity. The IFNG gene codes for interferon-γ (IFN-γ), a cytokine that plays a key role in host defense against intracellular pathogens. Indeed, single nucleotide polymorphisms (SNPs) in IFNG have been evaluated in several genetic epidemiological studies, and the SNP +874T>A, the +874T allele, more specifically, has been associated with protection against infectious diseases, especially tuberculosis. Here, we evaluated the association of the IFNG locus with leprosy enrolling 2,125 Brazilian subjects. First, we conducted a case-control study with subjects recruited from the state of São Paulo, using the +874 T>A (rs2430561), +2109 A>G (rs1861494) and rs2069727 SNPs. Then, a second study including 1,370 individuals from Rio de Janeiro was conducted. Results of the case-control studies have shown a protective effect for +874T carriers (OR(adjusted) = 0.75; p = 0.005 for both studies combined), which was corroborated when these studies were compared with literature data. No association was found between the SNP +874T>A and the quantitative Mitsuda response. Nevertheless, the spontaneous IFN-γ release by peripheral blood mononuclear cells was higher among +874T carriers. The results shown here along with a previously reported meta-analysis of tuberculosis studies indicate that the SNP +874T>A plays a role in resistance to mycobacterial diseases.

Abstract
OBJECTIVE Interferon gamma (IFN-gamma) is a pro-inflammatory cytokine playing a pivotal role in both innate and adaptive immune responses. A single nucleotide polymorphism located in the first intron of the human IFN-gamma gene can influence the secretion of cytokine. Therefore, we aimed to investigate the association of IFN-gamma T/A gene polymorphism with the risk of cervical cancer. DESIGN Case-control study. SETTING Uttar Pradesh State in India. SAMPLE Two hundred cases with histologically proven cancer of the cervix and healthy controls (n = 230), age and ethnicity matched were recruited in this study. METHODS Genotyping was performed for bi-allelic +874 (T/A) polymorphism of IFN-gamma by amplification refractory mutation system method. MAIN OUTCOME MEASURES Low producer IFN-gamma +874 AA genotype was associated with high risk for cervical cancer, which further modulated the increased risk in tobacco users. RESULTS IFN-gamma AA genotype which is low producer of IFN-gamma was associated with increased risk of cervical cancer (OR = 2.43, P = 0.003). Allele A was at 1.54-fold increased risk of cervical cancer (OR=1.54, P = 0.002). The AA genotype showed statistically significant risk with high stage (III + IV) of cervical cancer (OR = 4.99, P = 0.001). In tobacco users, AA genotype showed significantly increased susceptibility to cervical cancer (OR = 5.08, P = 0.010). CONCLUSION Variation in IFN-gamma +874 AA genotype because of ethnicity in north-Indian population may represent an important susceptibility biomarker for cervical cancer risk as well as other diseases and should be explored further.

Abstract
UNLABELLED Diabetic peripheral neuropathy (DPN) is a major global health threat and a common complication of diabetes. Peripheral nerve complications due to irregular cytokine production are eminent factors in many inflammatory diseases. The present study focused on gene polymorphisms of pro and anti-inflammatory cytokines that may be responsible for nerve damage in diabetic neuropathy. We examined three common functional SNPs primarily at the positions on genes of tumor necrosis alpha (TNFalpha) -308G/A, interferon gamma (IFNgamma) +874A/T and interleukin (IL) 10 -1082G/A in order to establish their association with peripheral neuropathy in type 2 diabetes. RESULTS Genotypic frequencies obtained from TNFalpha -308G/A gene analysis in DPN group comprised 86.4% of G/A, 10.6% of G/G and 3% of A/A genotype, where as the control group had 94% of G/A, 2% of G/G and 4% of A/A which could not reach the statistical significance with the disease after Bonferroni correction. The IFNgamma +874 A/T polymorphism in patient group revealed 33.3% of A/A, 47.5% of A/T and 19.2% of T/T genotype. The A/A genotype had attained statistical significance of P=0.04 (P corrected); OR 2; 95% CI 1.14-3.64 when compared to controls. The IL10 -1082 G/A polymorphism in the patient group has showed 62.6% of A/A, 21.2% of G/A, 16.2% of G/G genotype, revealing significant association with G/G genotype (P<0.01, OR 2.9; 95% CI 1.47-5.84) when compared to controls. CONCLUSION Our findings indicate that the tested markers within the IFNgamma and IL-10 genes, but not the TNFalpha gene, are significantly associated with peripheral neuropathy in South Indian type 2 diabetic patients. The study shows that the 'high-producer' IL-10 -1082 G/G genotype and the 'low-producer' IFNgamma +874 A/A genotype may be responsible for the down regulation of immune response leading to inflammation in this setting.

Abstract
OBJECTIVES The goal of this study was to identify cytokines that may predict high-risk HPV clearance or persistence in untreated patients with mild dysplasia or less of the uterine cervix. METHODS A prospective analysis was performed on 57 patients who harbored high-risk HPV with histologically verified mild dysplasia or less between May 2005 and March 2006. All patients underwent follow-up evaluation at 12 months. Real-time PCR was used to quantify interferon-gamma (IFN-gamma), interleukin-10 (IL-10), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) transcripts. Hybrid Capture II testing was used to detect HPV DNA. RESULTS Among the 57 patients that were untreated with mild dysplasia, or less, 46 (80.7%) had no detectable HPV after 12 months of follow-up. Univariate analysis showed that a negative HPV test, of untreated mild dysplasia or less, occurred in 93.3% (28/30) of patients who were IFN-gamma-positive and in 66.7% (18/27) of patients who were IFN-gamma-negative (P=0.0109). Other factors such as age, lesion grade in the colposcopic biopsy, IL-10, IL-6, TNF-alpha, day of menstrual cycle, smoking, and use of oral contraceptives were not significantly associated with high-risk HPV negative or positive results after 12-months of follow-up in patients with untreated mild dysplasia or less. The multivariate logistic regression analysis showed that only IFN-gamma-positive results were significantly associated with clearance of high-risk HPV after 12 months of follow-up (OR: 8.26; 95% CI: 1.24-54.94). CONCLUSIONS These results suggest that intralesional IFN-gamma may be a prognostic marker for clearance of high-risk HPV.

Abstract
Cervical cancer is a complex disease with multiple environmental and genetic determinants. In this study, we sought an association between polymorphisms in immune response genes and cervical cancer using both single-locus and multi-locus analysis approaches. A total of 14 single nucleotide polymorphisms (SNPs) distributed in CD28, CTLA4, ICOS, PDCD1, FAS, TNFA, IL6, IFNG, TGFB1 and IL10 genes were determined in patients and healthy individuals from three independent case/control sets. The first two sets comprised White individuals (one group with 82 cases and 85 controls, the other with 83 cases and 85 controls) and the third was constituted by non-white individuals (64 cases and 75 controls). The multi-locus analysis revealed higher frequencies in cancer patients of three three-genotype combinations [CD28+17(TT)/IFNG+874(AA)/TNFA-308(GG), CD28+17(TT)/IFN+847(AA)/PDCD1+7785(CT), and CD28 +17(TT)/IFNG+874(AA)/ICOS+1564(TT)] (P < 0.01, Monte Carlo simulation). We hypothesized that this two-genotype [CD28(TT) and IFNG(AA)] combination could have a major contribution to the observed association. To address this question, we analyzed the frequency of the CD28(TT), IFNG(AA) genotype combination in the three groups combined, and observed its increase in patients (P = 0.0011 by Fisher's exact test). The contribution of a third polymorphism did not reach statistical significance (P = 0.1). Further analysis suggested that gene-gene interaction between CD28 and IFNG might contribute to susceptibility to cervical cancer. Our results showed an epistatic effect between CD28 and IFNG genes in susceptibility to cervical cancer, a finding that might be relevant for a better understanding of the disease pathogenesis. In addition, the novel analytical approach herein proposed might be useful for increasing the statistical power of future genome-wide multi-locus studies.

Abstract
Infection with high-risk human papillomavirus (HR-HPV) is a necessary but not a sufficient event in the development of cervical cancer, as most infections regress without intervention. Thus, genetic host factors and cellular immune responses could be potential modifiers for the risk of developing cervical cancer. In particular, p53 is considered as the most critical tumour suppressor gene and is involved in regulating cell division. The polymorphism on p53, which encodes either a proline or an arginine amino acid residue at codon 72, has been reported as a possible risk factor for cervical disease. This polymorphism has been shown to differentially affect the efficiency of degradation of p53 protein mediated by HR-HPV E6 oncoprotein. Women with histologically proven cancer of the cervix (n = 111) and hospital-based controls (n = 143) were included in this study. The patients and controls were from the Western Cape Province in South Africa. Genotyping of the p53 polymorphism was conducted using polymerase chain reaction and restriction fragment-length polymorphism method. The distributions of the allelic frequencies were stratified in both patients and controls into two South African ethnic population groups. In this study, we observed no association between the distribution of p53 polymorphism and susceptibility to cervical cancer in the Western Cape Province populations (P = 0.466). However, the frequency of the Pro/Pro residue at codon 72 was increased in the South African population when compared to Caucasians, Indians and Portuguese population groups. Notably, as the distribution of the Pro/Pro at codon 72 of p53 gene was significantly different (P < 0.05) between the control groups of South Africa and other population groups. This result suggests that ethnic disparity may influence the levels of p53 produced.

Abstract
Black women have a lower incidence of gynecologic cancers but they have a higher mortality associated with their disease. The etiology of the racial disparity in outcome among gynecologic cancer patients is multifactoral and site-specific. Black women with endometrial cancer often present with more advanced stage tumors that are associated with a worse prognosis compared with White women. Evidence suggests that observed disparities in outcome are due to inequalities in treatment or differing biologic etiologies. For cervix cancer, studies have suggested that survival among Black women may be lower than survival among White women that develop this disease. This occurs despite evidence that indicates that Pap smears are utilized similarly by Black and White women for cervix cancer screening. These differences in outcome may become less pronounced when comorbidities are accounted for and inequalities in treatment are eliminated. For ovarian cancer patients, survival has improved with the use of contemporary therapies over the past 30 years in Whites but less so for Blacks. This may be due to differences in the likelihood of primary surgical cytoreductions, which are performed less frequently in some Black women because of extensive metastatic spread or comorbidities. The observed decreases in survival for all 3 gynecologic cancers potentially may be affected by socioeconomic status of the patient in some healthcare settings. An improved understanding of the causative factors associated with racial disparities in gynecologic cancer outcome is necessary to facilitate efforts aimed at correcting this important healthcare problem.

Abstract
Cytokines play a crucial role in the pathogenesis of autoimmune thyroid disease. The aim of this study was to investigate the relationship of the single base change polymorphic variants identified in the first intron of interferon-gamma (IFN-gamma) (+874 T/A) with susceptibility to thyroid dysfunctions. A total of 340 subjects were included in the study comprising of 190 patients (104 patients with Hashimoto's thyroiditis, 26 with non-Hashimoto's hypothyroidism and 60 Graves' disease) and 150 controls. Genotyping was done by amplification refractory mutation system-polymerase chain reaction using a set of sequence-specific primers. Statistical analysis revealed a significant association between high IFN-gamma-producing genotype TT and Hashimoto's thyroiditis compared to controls (P value < 0.001). On the other hand, the frequency of genotype TT was decreased in patients with Graves' hyperthyroidism with a significant increase in low IFN-gamma-producing genotype AA among this group (P = 0.03). To conclude the results of the study suggest a differential association of high- and low-producing alleles of IFN-gamma gene with Hashimoto's thyroiditis and Graves' disease. The high IFN-gamma-producing allele T was observed to be associated with Hashimoto's thyroiditis in the present study where as in Graves' hyperthyroidism the association was observed to be stronger with the low producing allele A.

Abstract
Background Cervical cancer is due to infection with specific high-risk types of human papillomavirus (HPV). Although the incidence of genital HPV infection in various population groups is high, most of these regress without intervention. Investigating genetic host factors and cellular immune responses, particularly cytokines, could help to understand the association between genital HPV infection and carcinogenesis. The tumor necrosis factor alpha (TNF-α) cytokine plays an important role in all stages of cervical cancer and has the ability to induce the regression of human tumors. Therefore the aim of the study was to investigate the allelic distribution of -308 TNF-α gene polymorphism in South African women with cervical cancer compared to control women. Methods Included in our study were women with histologically proven cancer of the cervix (n = 244) and hospital-based controls (n = 228). All patients and controls were from mixed race and black population groups in South Africa. The detection of a bi-allelic -308 (A/G) polymorphism in the promoter region of TNF-α was investigated using the amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) technique. The distributions of the allelic frequencies were stratified in both patients and controls into two South African ethnic population groups. Results In this study we observed no association between the distribution of -308 TNF-α polymorphism and the risk of developing cervical cancer even after combining the data from the two ethnic populations (X2 = 2.26). In addition, using the chi-squared test we found no significant association between the known risk factors for cervical cancer and the allele distribution of -308 TNF-α. However, the frequency of the rare high-producing allele -308A of TNF-α was significantly lower in the South African population when compared to Caucasians and Chinese population groups. Conclusion We demonstrated no association between -308 TNF-α polymorphism and the risk of cervical cancer among two South African ethnic population groups. However, as the distribution of the -308A TNF-α was notably different between the control groups of South Africa and other population groups this result suggests that ethnic disparity may influence the levels of TNF-α produced.

Abstract
Beyond human papillomavirus (HPV) infection, host genetic factors may contribute to cervical carcinogenesis. This study aims to test the hypothesis that CA-dinucleotide repeat polymorphism in the first intron of the interferon-gamma (IFN-gamma) gene is associated with HPV-initiated cervical carcinogenesis. A hospital-based case-control study including patients with low-grade squamous intraepithelial lesions (LSILs; n = 93), high-grade squamous intraepithelial lesions (HSILs; n = 123) and invasive carcinomas (n = 153) of the uterine cervix, as well as 1:1 age-matched controls, was conducted. The IFN-gamma genotype was determined by PCR and capillary electrophoresis with internal standards. HPV genotype was determined by consensus PCR and reverse line blot hybridization. Genotypes containing the 12 or 14 allele (12 or 14 CA repeats) were significantly more common in patients with HSILs than in controls (46% vs. 22%; OR = 3.0; 95% CI = 1.7-5.2; p < 0.0001). In contrast, genotypes containing 13 and 18 were significantly more common in controls than in patients with HSILs (76% vs. 53%; OR = 0.3; 95% CI = 0.2-0.6; p = 0.0001) or squamous cell carcinomas (74% vs. 63%; OR = 0.6; 95% CI = 0.4-1.0; p = 0.037). The frequency of the 12 and 14 genotypes increased significantly in accordance with the severity of cervical carcinogenesis (p(test for trend) = 0.0002), whereas the 13 and 18 genotypes showed the opposite trend (p(test for trend) = 0.007). Comparing IFN-gamma genotype and HPV status, 18-containing genotypes were more frequently found in HPV(+) LSILs, and 12-containing genotypes were less frequently found in HPV(+) HSILs. Compared with non-13 genotypes, 13 genotype HSILs were more frequently infected with HPV58 (70% vs. 45%) and less frequently infected with HPV18 (0% vs. 16%; p= 0.007). Genetic polymorphism of the IFN-gamma gene is associated with individual susceptibility to cervical carcinogenesis. This polymorphism correlates with HPV infection in a disease- and type-specific manner.

Abstract
The role of A/G polymorphism at nucleotide -1082 in the interleukin-10 (IL-10) promoter was assessed by following the disease course of 253 patients who had had a routine diagnostic Hybrid Capture human papillomavirus (HPV) test because of cytologic or colposcopic abnormalities of the uterine cervix. At baseline, 97 (78%) of the 125 high-risk HPV-positive and 83 (65%) of the 128 HPV-negative patients had equivocal cytologic atypia classified as P3 by the Papanicolaou classification, and the rest of the patients had mild colposcopic atypia with cytologic results of no oncogenic significance. In the high-risk HPV-infected patients, the frequency distribution of the nt -1082 genotypes (A/A: 28%; A/G: 52%; G/G: 20%) did not differ significantly from that in the controls (A/A: 25%; A/G: 51%; G/G: 24%; p = 0.70). On the other hand, the nt -1082 G allele tended to decrease susceptibility to equivocal cytologic atypia unrelated to HPV infection (A/G: OR = 0.56 [95% CI: 0.31-1.02], G/G: OR = 0.27 [95% CI: 0.11-0.63], p for trend = 0.05). With respect to the development of high-grade cervical intraepithelial neoplasia (CIN), the established risk factors, such as high-risk HPV infection (RR = 104.6, 95% CI: 14.2-769.9) and cytologic atypia (RR = 9.6, 95% CI: 2.34-39.7) but not the various nt -1082 genotypes (A/A: reference; A/G: RR = 1.11 [95% CI: 0.59-2.08]; G/G: RR = 0.62 [95% CI: 0.25-1.50]) were found to increase the risk for high-grade CIN. In conclusion, the nt -1082 polymorphism had no influence on the early phase of cervical carcinogenesis but may determine different susceptibilities to cervical abnormalities unrelated to HPV infection.
