Immunogenetic Determinants of Susceptibility to Head and Neck Cancer in the Million Veteran Program Cohort. Cancer Res 2023; 83:386-397. [PMID: 36378845 PMCID: PMC9896026 DOI: 10.1158/0008-5472.can-22-1641] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 09/02/2022] [Accepted: 11/10/2022] [Indexed: 11/16/2022]
Abstract
Increasing rates of human papillomavirus (HPV)-driven oropharyngeal cancer (OPC) have largely offset declines in tobacco-associated head and neck squamous cell carcinoma (HNSCC) at non-OPC sites. Host immunity is an important modulator of HPV infection, persistence, and clearance, and also of immune evasion in both virally- and nonvirally-driven cancers. However, the association between collective known cancer-related immune gene variants and HNSCC susceptibility has not been fully characterized. Here, we conducted a genetic association study in the multiethnic Veterans Affairs Million Veteran Program cohort, evaluating 16,050 variants in 1,576 immune genes in 4,012 HNSCC cases (OPC = 1,823; non-OPC = 2,189) and 16,048 matched controls. Significant polymorphisms were further examined in a non-Hispanic white (NHW) validation cohort (OPC = 1,206; non-OPC = 955; controls = 4,507). For overall HNSCC susceptibility in NHWs, we discovered and validated a novel 9q31.1 SMC2 association and replicated the known 6p21.32 HLA-DQ-DR association. Six loci/genes for overall HNSCC susceptibility were selectively enriched in African-Americans (6p21.32 HLA-G, 9q21.33 GAS1, 11q12.2 CD6, 11q23.2 NCAM1/CD56, 17p13.1 CD68, 18q22.2 SOCS6); all 6 genes function in antigen-presenting regulation and T-cell activation. Two additional loci (10q26 DMBT1, 15q22.2 TPM1) were uncovered for non-OPC susceptibility, and three loci (11q24 CRTAM, 16q21 CDH5, 18q12.1 CDH2) were identified for HPV-positive OPC susceptibility. This study underscores the role of immune gene variants in modulating susceptibility for both HPV-driven and non-HPV-driven HNSCC. Additional large studies, particularly in racially diverse populations, are needed to further validate the associations and to help elucidate other potential immune factors and mechanisms that may underlie HNSCC risk. SIGNIFICANCE Several inherited variations in immune system genes are significantly associated with susceptibility to head and neck cancer, which could help improve personalized cancer risk estimates.

J Med Virol 2021; 93:4949-4956. [PMID: 33739474 DOI: 10.1002/jmv.26946] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 03/11/2021] [Accepted: 03/15/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The chronicity or clearance of hepatitis B virus (HBV) infection depends on viral and genetic variables. The immune response against HBV is thought to be responsible for viral persistence or clearance. Cytokines such as interleukin 1-2B (IL1-2B) involved in the T-helper 1 system are key mediators in the defence mechanisms against viral infection and play a role in the regulation of HBV clearance during infection. We aimed to examine whether the polymorphic variant TaqI polymorphism in the 3'-untranslated region (3'-UTR; rs3212227) suspected to modulate interleukin-levels of IL-12B has an influence on the risk of development of chronicity after HBV exposure. METHODS Genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism method for 236 patients with chronic hepatitis B (CHB) and 240 controls from different cities of Tunisia recruited in the Pasteur Institute of Tunisia between January 2017 and December 2018. RESULTS We found that the IL-12B polymorphism was associated with a significantly increased risk of CHB in patients (p = 1 × 10-3 ; χ 2 = 10.31 and odds ratio [OR] = 2.14; 95% confidence interval [CI] = 1.30-3.52) when AC/CC variant genotypes were compared with the wild-type AA homozygote. Statistical significance was found when CHB-males were compared with CHB-females (p = 2 × 10-7 ; χ 2 = 26.62 and p = 1 × 10-3 ; χ 2 = 10.36, for genotypic and allelic frequencies, respectively). Also, CHB-patients carrying C-allele less than 50-years were at an increased risk of developing chronic HBV infection than patients more than 50-years (p = 6.1 × 10-5 ; χ 2 = 16.07). CONCLUSIONS These results suggest that the C-allele would affect susceptibility to chronicity after HBV exposure in Tunisian patients especially for males less than 50-years. Age and sex have an influence on this polymorphism in CHB Tunisian patients.

Abstract
Objective Head and neck cancers are mostly composed of head and neck squamous cell carcinoma (HNSCC). The incidence and mortality of HNSCC are higher in countries with emerging health care systems, particularly Africa. Given that they are more genetically diverse, characterization of polymorphism in African HNSCC may result in the identification of distinct molecular targets as compared with the known HNSCC candidate genes. This study objective is to review the current evidence of genetic data on HNSCC among African populations as well as to demonstrate any distinctions as compared with known candidate genes and to appraise any research gaps. Data Sources Publications that interrogated susceptible gene polymorphisms to African-based populations with cancer were reviewed for this study. Review Methods Our search methodology was modeled after the Cochrane systematic review protocol, which included MeSH terms and keywords related to cancer, polymorphisms, and African countries. Results Seven articles studying 2 HNSCC cancer types in 3 of 54 African countries met the inclusion criteria. Thirteen polymorphisms from 10 genes were screened (NOS3, CYP1A1, CYP2D6, NAT1, NAT2, NQO1, IL-10, IL-12, IL-8, COX2). All articles were screened for polymorphisms based on a polymerase chain reaction–based technique. All polymorphs suggested association to HNSCC, with 10 of 13 polymorphs demonstrating a statistically significant association. Conclusion Studies on known HNSCC candidate genes should be undertaken in Africa, particularly among sub-Saharan Africans. Importantly, these studies should be large scale with multiple HNC sites and with use of high-throughput methods.

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
The MHC class I chain-related molecule A (MICA) is a ligand for the activating natural killer (NK) cell receptor NKG2D. A part from its genetic diversity, MICA is characterized by the presence of membrane-bound and soluble isoform (sMICA) and by the propensity to elicit antibody-mediated allogeneicity (MICA Abs). Altogether such properties are important in the cancer setting. Here, we investigated whether MICA polymorphism, serum level of sMICA and MICA antibodies (Abs) may influence nasopharyngeal carcinoma (NPC) risk. 274 NPC naïve of treatment patients and 275 healthy individuals, all originating from Tunisia were included and genotyped. Among them, 160 sera from patients and 51 from controls were analyzed for the sMICA level by ELISA and were tested for the presence of MICA Abs by Luminex assay. The statistical analysis showed that: (1) we extend and confer our previous finding concerning Val/Val association with risk of NPC (p = .02, OR = 1.56; 95%CI [1.12-2.11]). (2) The higher level of sMICA characterized patients advanced stage of the disease. (3) The 18 (78%) of patients having MICA Abs exhibit all a non-advanced stage of the tumor extension at presentation. MICA129 Met /Val, sMICA and MICA Abs could be potential biomarkers of prediction, the diverse staging of NPC and hence prognostic and treatment.

Abstract
Nasopharyngeal carcinoma (NPC) is a common malignant neoplasm of the head and neck which is harmful to human's health. Radiotherapy is commonly used in the treatment of NPC and it induces immediate cell cycle arrest and cell apoptosis. However, the mechanism remains unknown. Evidences suggested the activation of Ataxia telangiectasia mutated (ATM) pathway and Smad pathway are 2 of the important crucial mediators in the function of radiotherapy. In this study, we performed in vitro assays with human nasopharyngeal carcinoma CNE-2 cells and in vivo assays with nude mice to investigate the role of the ATM and Smad pathways in the treatment of nasopharyngeal carcinoma with radiotherapy. The results suggested that radiation induced activation of ATM pathway by inducing expression of p-ATM, p-CHK1, p-CHK2, p15 and inhibiting expression of p-Smad3. In addition, Caspase3 expression was increased while CDC25A was decreased, leading to cell cycle arrest and cell apoptosis. On the other hand, activation of Smad3 can inhibited the ATM pathway and attenuated the efficacy of radiation. In summary, we suggest that both ATM and Smad pathways contribute to the cell cycle arrest and cell apoptosis during nasopharyngeal carcinoma cells treated with radiation.

Genetic modifications of cytokine genes and Toxoplasma gondii infections in pregnant women. Microb Pathog 2018; 121:283-292. [PMID: 29859292 DOI: 10.1016/j.micpath.2018.05.048] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2017] [Revised: 05/17/2018] [Accepted: 05/28/2018] [Indexed: 01/05/2023]
Abstract
PURPOSE Toxoplasma gondii causes one of the most common intrauterine infections worldwide, thus being a severe threat during pregnancy. IL1, IL6, IL10, IL12, and TNF-α cytokines were reported to be involved in immune responses to infections with T. gondii. The research was aimed to reveal relationships between genetic changes within the polymorphisms of these cytokine genes and the incidence of T. gondii infection among pregnant women, as well as congenital transmission of the parasite to the foetuses of their infected mothers. METHODS The primary study was performed in 148 Polish pregnant women, including 74 T. gondii-infected patients and 74 age-matched uninfected individuals; and further analysis - among the additional 142 pregnant women. Genotypes within IL1A -889 C>T, IL1B +3954 C>T, IL6 -174 G>C, IL10 -1082 G>A, IL12B -1188 A>C and TNFA -308 G>A single nucleotide polymorphisms (SNPs) were determined, using self-designed nested PCR-RFLP assays. Randomly selected PCR products, representing distinct genotypes in the analyzed polymorphisms, were confirmed by sequencing, using the Sanger method. A statistical analysis was carried out of relationships between genetic alterations within studied SNPs and the occurrence of T. gondii infection, using the following tools: cross-tabulation, Pearson's Chi-square test and the logistic regression model to estimate genetic models of inheritance. A power analysis of statistically significant outcomes was performed by Cramér's V test. RESULTS A multiple-SNP analysis showed TC haplotype for IL1A and IL1B SNPs to be significantly associated with a decreased risk of the parasitic infection (OR 0.41, P≤0.050). The association remained important after power analysis (Cramér's V = 0.39, χ2 = 7.73, P≤0.050), and the additional analysis with larger groups of patients (OR 0.47, P≤0.050). Moreover, the CCCAGA complex variants were for all the studied polymorphisms at an increased risk of T. gondii infection (OR 8.14, P≤0.050), although this strong relationship was not significant in the further analysis (Cramér's V = 0.76, χ2 = 26.81, P = 0.310). Regarding the susceptibility to congenital transmission of T. gondii from mothers to their foetuses among the infected pregnant women, the presence of GA heterozygotic status within IL10 polymorphism significantly increased the risk of parasitic transmission (OR 5.73 in the codominant model and OR 5.18 in the overdominant model; P≤0.050). The correlation stayed important in the power analysis (Cramér's V = 0.29, χ2 = 6.03, P≤0.050), although it was non-significant in larger groups of patients. Important relationships specific for the first study cohort remained non-significant in the second group of studied pregnant women. CONCLUSIONS Within the analyzed cohort of Polish pregnant women, the genetic modifications from SNPs of genes, encoding both the proinflammatory IL1α, IL1β, IL6, IL12 and TNF-α, and anti-inflammatory IL10 cytokines, may have been associated with susceptibility to T. gondii infection. It is the first study on the contribution of cytokine genes polymorphisms to the occurrence of T. gondii infection during pregnancy. Further studies for other populations of pregnant women would be justified to reveal a detailed role of the analyzed polymorphisms for the occurrence of T. gondii infections during pregnancy.

Abstract
Many molecular epidemiologic studies have explored the possible links between interleukin-12 (IL-12) polymorphisms and various cancers. However, results from these studies remain inconsistent. This meta-analysis is aimed to shed light on the associations between three common loci (rs568408, rs2243115, rs3212227) of IL-12 gene and overall cancer risk. Our meta-analysis finally included 33 studies comprising 10,587 cancer cases and 12,040 cancer-free controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the cancer risk. We observed a significant association between IL-12B rs3212227 and overall cancer risk, especially in hepatocellular carcinoma, nasopharyngeal cancer, and among Asians. IL-12A polymorphisms (rs2243115 and rs568408) were found no influence on overall cancer risk. Nevertheless, stratification analyses demonstrated that rs568408 polymorphism contributed to increasing cancer risk of Caucasians and cervical cancer. And, rs2243115 may enhance the risk of brain tumor. These findings provided evidence that IL-12 polymorphisms may play a potential role in cancer risk.

Association of p53 codon72 Arg>Pro polymorphism with susceptibility to nasopharyngeal carcinoma: evidence from a case-control study and meta-analysis. Oncogenesis 2016; 5:e225.

Abstract
Tumor suppressor p53 is a critical player in the fight against cancer as it controls the cell cycle check point, apoptotic pathways and genomic stability. It is known to be the most frequently mutated gene in a wide variety of human cancers. Single-nucleotide polymorphism of p53 at codon72 leading to substitution of proline (Pro) in place of arginine (Arg) has been identified as a risk factor for development of many cancers, including nasopharyngeal carcinoma (NPC). However, the association of this polymorphism with NPC across the published literature has shown conflicting results. We aimed to conduct a case–control study for a possible relation of p53 codon72 Arg>Pro polymorphism with NPC risk in underdeveloped states of India, combine the result with previously available records from different databases and perform a meta-analysis to draw a more definitive conclusion. A total of 70 NPC patients and 70 healthy controls were enrolled from different hospitals of north-eastern India. The p53 codon72 Arg>Pro polymorphism was typed by polymerase chain reaction, which showed an association with NPC risk. In the meta-analysis consisting of 1842 cases and 2330 controls, it was found that individuals carrying the Pro allele and the ProPro genotype were at a significantly higher risk for NPC as compared with those with the Arg allele and the ArgArg genotype, respectively. Individuals with a ProPro genotype and a combined Pro genotype (ProPro+ArgPro) also showed a significantly higher risk for NPC over a wild homozygote ArgArg genotype. Additionally, the strength of each study was tested by power analysis and genotype distribution by Hardy–Weinberg equilibrium. The outcome of the study indicated that both allele frequency and genotype distribution of p53 codon72 Arg>Pro polymorphism were significantly associated with NPC risk. Stratified analyses based on ethnicity and source of samples supported the above result.

Abstract
p53 and glutathione S-transferase M1 (GSTM1) are the most popular suppressor genes. Several previous studies demonstrated positive associations of these gene polymorphisms with numerous cancer types, including hepatocellular cancer, while the association between p53/GSTM1 polymorphisms and the nasopharyngeal carcinoma (NPC) risk was inconsistent and underpowered. However, no studies investigating the combinational effect of these two genes on NPC risk were performed. To confirm the effects of p53 and GSTM1 polymorphisms on the risk of NPC, a meta-analysis of all the available previous studies associating p53 and GSTM1 with the risk of NPC was performed. A comprehensive search of PubMed, Web of Science and SD database until November 2014 was performed to identify the relevant studies. The data were extracted by two independent authors and pooled odds ratio (OR) with 95% confidence interval (CI) was calculated. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. Finally, five studies with 1,419 cases and 1,707 controls were included for the p53 polymorphism and three studies with 837 cases and 1,299 controls were included for the GSTM1 polymorphism. Regarding p53, a significantly increased NPC risk was observed in the overall population (C vs. G, OR, 1.245; 95% CI, 1.045-1.483; P=0.014; additive models: CC vs. GG, OR, 1.579; 95% CI, 1.100-2.265; P=0.013 and CG vs. GG, OR, 1.230; 95% CI, 1.039-1.456; P=0.016; dominant model, OR, 1.321; 95% CI, 1.127-1.549; P=0.001; recessive model, OR, 1.429; 95% CI, 1.017-2.009; P=0.040). Concerning GSTM1, a significantly increased NPC risk was observed in the overall population (null versus non-null, OR, 1.282; 95% CI, 1.075-1.530; P=0.006). In the subgroup analyses stratified by the source of controls, a significant association of p53 with NPC risk was also demonstrated, while no association with GSTM1 was observed. Therefore, the p53 G72C polymorphism may have a susceptible role in the carcinogenesis of NPC, while genetic deletion of GSTM1 may contribute to increased susceptibility to NPC. Further large and well-designed studies are required to confirm this association.

Abstract
Glioma is one of the most aggressive and most common tumors of the central nervous system (CNS) in humans. The exact causes of glioma are not well known, but evidence suggests the involvement of genetic factors in addition to environmental risk factors. The present study aimed to determine whether polymorphisms in IL-10-1082A/G, IL-12p40 1188C/A, and IL-13+2044G/A (rs20541) are associated with the incidence of glioma in Iraqi patients. Ninety-six patients with different grades of glioma and 40 apparently healthy individuals were recruited. A blood sample and genomic DNA were collected from all subjects. The amplification refractory mutation system and sequence-specific primer polymerase chain reaction (PCR) were used for genotyping of IL-10-1082A/G and IL-12p40 1188C/A, respectively; whereas, the IL-13+2044G/A was detected by DNA sequencing after amplification of the genes by PCR. All SNPs were within Hardy-Weinberg equilibrium and each appeared in three genotypes in patients and controls. In IL-10-1082A/G, these genotypes frequencies were AA (75%), AG (22.93%) and GG (2.07%) in patients as compared to similar frequencies (62.5%), (27.5%) and (10%) respectively, in controls. The variant IL-12p40 1188C/A genotype was AA (72.92%), AC (23.96%), and CC (3.13%%) in patients as compared to 65%, 30%, and 5%, respectively, in controls. The frequencies of IL-13+2044G/A genotypes (GG, GA, and AA) were 89.58%, 9.37%, and 1.04% among patients versus 47.5%, 32.5% and 20%, respectively, among controls. These results suggest a protective role of mutant alleles G and A in IL-10-1082A/G and IL-13+2044G/A against gliomas. Further studies with more rigorous parameter designs will be needed to confirm the current findings.

Abstract
The P53 codon 72 polymorphism has been identified as a critical biomarker in modifying the risk of nasopharyngeal cancer (NPC). Many studies have investigated the association between the polymorphism of P53 codon 72 and NPC risk; however, the findings across the published studies are inconsistent and inconclusive. To acquire a more precise assessment for this association, we conducted an updated meta-analysis. The PubMed, Embase, Web of Science, and Wanfang databases were searched for relevant case-control studies. Totally, seven independent publications with 1,133 cases and 1,678 controls were retrieved. The pooled odds ratio (OR) with corresponding 95% confidence interval (95% CI) was calculated. Increased risk of NPC was observed among individuals carrying the variant allele and genotypes of P53 codon 72 (OR Pro vs. Arg = 1.32, 95% CI 1.18-1.47, P OR < 0.001; OR ProPro vs. ArgArg = 1.90, 95% CI 1.51-2.39, P OR < 0.001; OR ProArg + ProPro vs. ArgArg = 1.33, 95% CI 1.13-1.57, P OR = 0.001; OR ProPro vs. ArgArg + ProArg = 1.65, 95% CI 1.35-2.01, P OR < 0.001). Stratified analyses by ethnicity and source of controls also identified this significant relationship in Asians, Caucasians, and hospital-based case-control studies. There was no publication bias risk in our study. The updated meta-analysis supports the evidence that the polymorphism of P53 codon 72 is a risk factor for the development of NPC among the populations of both Asian and Caucasian.

Abstract
We analysed the association of a single nucleotide polymorphism (SNP) in the gene encoding the IL-12 subunit p40 (IL12B, rs3212227, A>C) with breast cancer. The SNPs allelic and genotypic frequencies were compared between patients (n = 191) and healthy (n = 194) women in a case-control study from Croatia. The major allele (A) was associated with susceptibility to breast cancer (P = 0.003; OR = 1.67; 95% CI: 1.17-2.38). Likewise, the minor allele (C) was significantly correlated with protection (P = 0.003; OR = 0.60; 95% CI: 0.42-0.86). At the genotype level, AA homozygosity was significantly associated with predisposition to disease (P = 0.013; OR = 1.68, 95% CI: 1.09-2.59), whereas the minor allele homozygosity (CC) was correlated with protection to disease (P = 0.020, OR = 0.28, 95% CI: 0.09-0.91). The heterozygous genotype showed no significant correlation with disease. The product of the IL12B gene (IL-12 p40) can either form a homodimeric cytokine or be part of two pro-inflammatory (IL-12 and IL-23) cytokines. It is presently unclear whether the major allele is associated with higher or lower protein levels of IL-12 p40 and IL-12 p70, which are critical in inflammation and adaptive immune responses. However, as the A allele is high producer of IL12B (p40) mRNA, these results might imply that higher levels of IL-12 p40 (either as homodimers or joined with one or both of the other two subunits) predispose to breast cancer.

Abstract
IL-12 plays a very important role in the development and progress of cancer. IL-12B rs3212227 polymorphism has been reported and many studies have focused on the role of this polymorphism in various cancers. However, the association between IL-12B rs3212227 polymorphism and cancer risk remains controversial. Therefore, we performed a systematic meta-analysis to estimate the overall cancer risk associated with this gene polymorphism and to quantify any potential between-study heterogeneity. PubMed and Embase databases were searched for case-control studies published up to April 1, 2012 that investigated IL-12B rs3212227 polymorphism and cancer risk. Odds ratios (OR) with 95 % confidence intervals (95 % CI) were used to access the strength of this association. Heterogeneity among articles and publication bias were also verified. Ten studies with 2,954 cancer patients and 3,276 healthy controls were included. This meta-analysis showed that there was a significant association between IL-12B rs3212227 polymorphism and overall cancer risk (CC/AC vs AA: OR = 1.32, 95 % CI = 1.06-1.63). When stratified by cancer type, we found a significant increased risk in cervical and nasopharyngeal cancer (OR = 1.34, 95 % CI = 1.04-1.73; OR = 2.03, 95 % CI = 1.57-2.63, respectively). In the stratified analysis, we also observed a similar association in population-based studies (OR = 1.34, 95 % CI = 1.00-1.80), Asian populations (OR = 1.33, 95 % CI = 1.06-1.67) and European populations (OR = 1.54, 95 % CI = 1.04-2.28). According to the results of our meta-analysis, IL-12B rs3212227 polymorphism probably is associated with a high risk of cancer.

Abstract
BACKGROUND Emerging evidence from preclinical and clinical studies has shown that interleukin-12 (IL-12) has some effectiveness against endogenously arising carcinogenesis. Several potentially functional polymorphisms of IL-12 gene have been implicated in cancer risk, but individually published studies showed inconclusive results. The aim of this study was to investigate the association between IL-12 polymorphisms and cancer risk. METHODS The MEDLINE, EMBASE, Web of science and CBM databases were searched for all articles published up to June 10, 2012 that addressed IL-12 polymorphisms and cancer risk. Statistical analyses were performed using RevMan 5.1.6 and STATA 12.0 softwares. RESULTS Eighteen studies were included with a total of 6463 cancer cases and 7412 healthy controls. We found that the 3'UTR A>C (rs3212227) polymorphism of IL-12B gene was associated with significantly increased overall risk of cancers using random effects model (C vs A: odds ratio [OR]=1.14, 95% confidence interval [CI]: 1.02-1.27; AC+CC vs AA: OR=1.20, 95%CI: 1.01-1.43). However, the 3'UTR G>A (rs568408), IVS2 T>A (rs582054) and 5'UTR T>G (rs2243115) polymorphisms of IL-12A gene did not appear to have an influence on cancer susceptibility. Further subgroup analyses showed that the 3'UTR A>C (rs3212227) polymorphism was associated with increased cancer risks in the subgroups of Asians, cervical and nasopharyngeal cancers. CONCLUSIONS Results from the current meta-analysis indicates that the 3'UTR A>C (rs3212227) polymorphism of IL-12B gene might be a potential biomarker for cancer risk among Asians, especially for cervical and nasopharyngeal cancers.

Abstract
Nasopharyngeal carcinoma (NPC) is thought to arise because of chronic inflammation. The correlation between nitric oxide (NO) production, a biomarker of inflammation and NPC development remains unexplored. To investigate this question, we performed a profile analysis on plasma collected from untreated, treated, remissive, cured and relapsing patients. Nitrites were measured to assess NO activity. We observed that increased nitrites concentrations in untreated and relapsing patients associated with tumor development. Moreover, nitrites levels were similar in remissive, cured and healthy individuals. Altogether, our results suggest that NO might be an interesting blood biomarker to monitor tumor growth in NPC patients.

Abstract
The last decade has seen the emergence of immunomodulators as therapeutic agents in cancer treatment. Interleukins (ILs) are a category of small cell-signaling molecules that organize communication and interaction between immune cells and therefore they could be used as perfect immunomodulators. IL-12 is a promising candidate for cancer immunotherapy since it plays a major role in development of antitumor immune response. Numerous studies report that IL-12 promotes an effective destruction of cancer cells both in vivo and in vitro. In addition, IL-12 has anti-angiogenic activity and it is able to dramatically decrease tumor-supportive activities of tumor-associated macrophages. The first part of the review is devoted to immunobiology of IL-12. Signaling pathways of IL-12 as well as clinical trials of this cytokine are discussed. The second part of the review is concerned on the inherited variations in IL-12A and IL-12B genes that could modulate cancer susceptibility, and as a consequence, possess predictive, therapeutic, or prognostic significance. It is known that functional single nucleotide polymorphisms (SNPs) in IL-12A and IL-12B genes may dramatically affect on protein expression level, or alter its functions, which may lead to immune disorders, autoimmune diseases, and eventually contribute to cancer occurrence. The list of genetic polymorphisms for further investigations might include the following: IL-12B_+1188A/C (rs3212227), IL-12A_+277G/A (rs568408), IL-12A_-798T/A (rs582054), IL-12A_-504T/G (rs190533), IL-12A_-1148T/C (rs2243123), and IL-12B_+16974 A/C. Perhaps, some of these SNPs may become an attractive target for oncogenomics and possibly could be used in programs of early cancer diagnosis as well as cancer prevention in the nearest future.

Abstract
BACKGROUND Type 2 diabetes mellitus is one of the most common types of endocrine disease and the immune system plays a predominant role in its pathogenesis. AIMS The present study aimed to examine known gene polymorphisms within IL-12B (+1188) region and its circulating serum levels in Type 2 diabetic patients from the southeastern region of Iran and compare them with unrelated controls. MATERIALS & METHODS In this clinical study, peripheral blood was collected from 114 Type 2 diabetic patients and 100 healthy controls. Serum levels of IL-12B were measured by ELISA. Genomic DNA was extracted from peripheral blood samples and polymorphisms at the +1188 position of the IL-12B gene were assessed using PCR restriction fragment-length polymorphism. RESULTS Our findings demonstrated that the AA genotype and the A allele of IL-12B were increased significantly in Type 2 diabetic patients when compared with controls. Our results also showed that the circulating levels of IL-12B were significantly decreased in Type 2 diabetic patients when compared with controls. CONCLUSION According to the findings of the current study, we concluded that IL-12B and its +1188 polymorphism may play a prominent role in the pathogenesis of Type 2 diabetes. Further replicative investigations using a larger sample size are essential to identify additional IL-12B genetic variants associated with a risk of Type 2 diabetes.

Abstract
Nasopharyngeal carcinoma (NPC) is an epithelial malignancy and has a remarkable geographic distribution, which is highly prevalent in southern China, Southeast Asia, and North Africa. Although most of the NPC are sporadic cases, the familial clustering of NPC has been demonstrated worldwide. Accumulating studies have proposed that the etiology of NPC is multi-stage and multi-factorial, involving genetic lesions, Epstein-Barr virus infection, and environmental exposure. Genetic variations result in differences in gene function, which in turn lead to different susceptibility to disease. Many studies have been carried out to dissect the genetic variants that contribute to NPC susceptibility. This article reviews the current progress of genetic studies to identify genes associated with NPC, focusing on the familial linkage and large-scale case-control study designs.

Semin Cancer Biol 2012; 22:107-16.

Abstract
While infection with Epstein-Barr virus (EBV) is known to be an essential risk factor for the development of nasopharyngeal carcinoma (NPC), other co-factors including genetic factors are thought to play an important role. In this review, we summarize association studies conducted over the past decade to evaluate the role of genetic polymorphisms in NPC development. A review of the literature identified close to 100 studies, including 3 genome-wide association studies (GWAS), since 2000 that evaluated genetic polymorphisms and NPC risk in at least 100 NPC cases and 100 controls. Consistent evidence for associations were reported for a handful of genes, including immune-related HLA Class I genes, DNA repair gene RAD51L1, cell cycle control genes MDM2 and TP53, and cell adhesion/migration gene MMP2. However, for most of the genes evaluated, there was no effort to replicate findings and studies were largely modest in size, typically consisting of no more than a few hundred cases and controls. The small size of most studies, and the lack of attempts at replication have limited progress in understanding the genetics of NPC. Moving forward, if we are to advance our understanding of genetic factors involved in the development of NPC, and of the impact of gene-gene and gene-environment interations in the development of this disease, consortial efforts that pool across multiple, well-designed and coordinated efforts will most likely be required.
