Shraim R, Farran MZ, He G, Marunica Karsaj J, Zgaga L, McManus R. Systematic review on gene-sun exposure interactions in skin cancer. Mol Genet Genomic Med 2023; 11:e2259. [PMID: 37537768 PMCID: PMC10568388 DOI: 10.1002/mgg3.2259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 06/15/2023] [Accepted: 07/19/2023] [Indexed: 08/05/2023] Open
Abstract
BACKGROUND The risk of skin cancer is determined by environmental factors like ultraviolet radiation (UVR), personal habits like time spent outdoors and genetic factors. This review aimed to survey existing studies in gene-environment (GxE) interaction on skin cancer risk, and report on GxE effect estimates. METHODS We searched Embase, Medline (Ovid) and Web of Science (Core Collection) and included only primary research that reported on GxE on the risk of the three most common types of skin cancer: basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma. Quality assessment followed the Newcastle-Ottawa Scale. Meta-analysis was not possible because no two studies examined the same interaction. This review was registered on PROSPERO (CRD42021238064). RESULTS In total 260 records were identified after exclusion of duplicates. Fifteen studies were included in the final synthesis-12 used candidate gene approach. We found some evidence of GxE interactions with sun exposure, notably, with MC1R, CAT and NOS1 genes in melanoma, HAL and IL23A in BCC and HAL and XRCC1 in SCC. CONCLUSION Sun exposure seems to interact with genes involved in pigmentation, oxidative stress and immunosuppression, indicating that excessive UV exposure might exhaust oxidative defence and repair systems differentially, dependent on genetic make-up. Further research is warranted to better understand skin cancer epidemiology and develop sun exposure recommendations. A genome-wide approach is recommended as it might uncover unknown disease pathways dependent on UV radiation.

Abstract
OBJECTIVE To investigate the association of genic region polymorphisms of FAS and FASL in Indian patients with oral cancer. STUDY DESIGN The study included 960 consenting control participants and patients with oral cancer. Genotyping was performed using Polymerase Chain Reaction -Restriction Fragment Length Polymorphism (PCR-RFLP). Cancer risk, 5-year survival, and hazards ratio (HRs), with respect to risk and clinical factors, were estimated using Fisher's exact test, Kaplan-Meier analysis, and Cox proportional hazards models. RESULTS FASL IVS2nt-124 'AG' increased risk in males with buccal mucosa cancer (BMC) but decreased risk in females. FAS 21196 'CT' decreased risk of tongue cancer (TC) and BMC in females. The survival of the patients also differed between sexes in TC and BMC. FAS 21196 'CT' increased HR by 23-fold in females with BMC when adjusted for age, stage, grade, LVS, PNI, tobacco use, and alcohol. 'TT' genotype increased the HR in females with BMC when adjusted for age, stage, grade, lymphovascular spread (LVS), perineural invasion (PNI), and perinodal spread (PNS). Our bioinformatic study revealed the presence of CTCF binding regions and CpG islands near FAS and FASL. CONCLUSIONS These single nucleotide polymorphisms (SNPs) altered the risk and survival of BMC and TC patients differentially that varied with clinical and risk factors.

Abstract
Aberrant apoptosis at the trophoblast-maternal interface and abnormal expression of Fas and Fas ligand (FasL) have been reported in complicated pregnancies with recurrent pregnancy losses (RPL) and preeclampsia. We assessed the prevalence of Fas and FasL genetic polymorphisms in Korean women with RPL and in fertile controls. In total, 306 women with RPL and 298 fertile controls were enrolled. Genotype distributions of Fas and FasL in RPL patients versus fertile controls were examined under the Hardy-Weinberg equilibrium. Fas -670 A/G genotype (AA versus AG versus GG, p = 0.340) and allele frequencies (A versus G, p = 0.412) were not different between the RPL and control groups. There was no difference in each Fas -1377 G/A and FasL -844 C/T genotype, and their allele frequencies. In addition, the unions of two zygosities of each genotype and their combined genotypes did not differ between two groups. No difference in the prevalence of Fas and FasL single-nucleotide polymorphisms (SNPs) was observed between women with RPL and fertile controls among Korean women. To determine the possibility of genetic polymorphisms in Fas and its ligand as risk factors for RPL, further studies in various races and a large study population are needed.

Abstract
We report a novel computational method, RegNetDriver, to identify tumorigenic drivers using the combined effects of coding and non-coding single nucleotide variants, structural variants, and DNA methylation changes in the DNase I hypersensitivity based regulatory network. Integration of multi-omics data from 521 prostate tumor samples indicated a stronger regulatory impact of structural variants, as they affect more transcription factor hubs in the tissue-specific network. Moreover, crosstalk between transcription factor hub expression modulated by structural variants and methylation levels likely leads to the differential expression of target genes. We report known prostate tumor regulatory drivers and nominate novel transcription factors (ERF, CREB3L1, and POU2F2), which are supported by functional validation.

Abstract
The Tasmanian devil (Sarcophilus harrisii) is threatened with extinction due to the spread of devil facial tumour disease. Polymorphisms in immune genes can provide adaptive potential to resist diseases. Previous studies in diversity at immune loci in wild species have almost exclusively focused on genes of the major histocompatibility complex (MHC); however, these genes only account for a fraction of immune gene diversity. Devils lack diversity at functionally important immunity loci, including MHC and Toll-like receptor genes. Whether there are polymorphisms at devil immune genes outside these two families is unknown. Here, we identify polymorphisms in a wide range of key immune genes, and develop assays to type single nucleotide polymorphisms (SNPs) within a subset of these genes. A total of 167 immune genes were examined, including cytokines, chemokines and natural killer cell receptors. Using genome-level data from ten devils, SNPs within coding regions, introns and 10 kb flanking genes of interest were identified. We found low polymorphism across 167 immune genes examined bioinformatically using whole-genome data. From this data, we developed long amplicon assays to target nine genes. These amplicons were sequenced in 29-220 devils and found to contain 78 SNPs, including eight SNPS within exons. Despite the extreme paucity of genetic diversity within these genes, signatures of balancing selection were exhibited by one chemokine gene, suggesting that remaining diversity may hold adaptive potential. The low functional diversity may leave devils highly vulnerable to infectious disease, and therefore, monitoring and preserving remaining diversity will be critical for the long-term management of this species. Examining genetic variation in diverse immune genes should be a priority for threatened wildlife species. This study can act as a model for broad-scale immunogenetic diversity analysis in threatened species.

Abstract
To investigate the association of the genetic variants of FAS/FASLG cell death pathway genes in male infertility, we genotyped the FAS -670A/G, -1377G/A, and FASLG -124A/G single-nucleotide polymorphisms (SNPs) by real-time polymerase chain reaction in 108 infertile men with idiopathic azoospermia and in 125 proven fertile controls. The distribution of genotypes and alleles for SNPs at FAS -1377G/A and FASLG -124A/G loci were determined not to be statistically different between the case and control groups. However, the genotype frequencies of SNPs, FAS -670AA and FAS -670AG, were found to be significantly different between the case and control groups. Whereas the FAS -670AA genotype might be regarded as a higher predisposition for idiopathic azoospermia, FAS -670AG could be interpreted to mean that this genotype provides protection against idiopathic azoospermia. The study of combined genotype and haplotype frequencies has found statistically significant differences between case and control subjects for some combinations. The AA-GG binary genotype for the FAS670 and FAS1377 loci couple, in particular, may have a high degree of predisposition to idiopathic azoospermia. Our results suggest that FAS -670A/G SNP may be a genetic predisposing factor of idiopathic azoospermia among southeastern Anatolian men. Larger studies are needed to verify these findings. Furthermore, our data indicated a possible linkage between the FAS and FASLG genes and idiopathic azoospermia.

Abstract
Fas and its ligand (FasL) play an important role in apoptosis and carcinogenesis. Therefore, the potential association of polymorphisms in the Fas (-670A>G, rs1800682; -1377G>A, rs2234767) and FasL (-844C>T, rs763110) with cancer risk has been widely investigated. However, all the currently available results are not always consistent. In this work, we performed a meta-analysis to further determine whether carriers of the polymorphisms in Fas and FasL of interest could confer an altered susceptibility to cancer. All relevant data were retrieved by PubMed and Web of Science, and 52 eligible studies were chosen for this meta-analysis. There was no association of the Fas -670A>G polymorphism with cancer risk in the pooled data. For the Fas -1377G>A and FasL -844C>T polymorphisms, results revealed that the homozygotes of -1377A and -844C were associated with elevated risk of cancer as a whole. Further stratified analysis indicated markedly increased risk for developing breast cancer, gastric cancer, and esophageal cancer, in particular in Asian population. We conclude that carriers of the Fas-1377A and the FasL -844C are more susceptible to the majority of cancers than non-carriers.

Abstract
Abnormal regulation of apoptosis can lead to carcinogenesis. Single nucleotide polymorphisms in apoptotic genes have been associated with cancer risk, such as the FAS rs2234767G/A polymorphism, which alters transcription of the FAS promoter. Downregulation of FAS, with resultant cellular resistance to death signals, has been found in many cancers. However, the association between the FAS rs2234767G/A polymorphism and cancer risk is still controversial. Here, we performed a meta-analysis including 41 articles (44 case-control studies, 17,814 cases and 24,307 controls) identified from PubMed and Chinese language (CNKI and WanFang) databases related to cancer susceptibility and the FAS rs2234767G/A polymorphism. We used odds ratios (ORs) and 95% confidence intervals (CIs) to assess the strength of the associations. We found that the rs2234767 G-allele was a protective factor for cancer risk (GG vs. AA: OR=0.88, 95% CI=0.79-0.98; GG+GA vs. AA: OR=0.87, 95% CI=0.79-0.96). Similar associations were detected in the "source of control", ethnicity, and cancer type subgroups. Further studies on a larger sample size and considering gene-environment interactions should be conducted to confirm the role of FAS polymorphisms, especially rs2234767G/A, in cancer risk.

Abstract
BACKGROUND The relationship between Fas -1377 G/A polymorphism and cancer susceptibility has been implicated in accumulating data. However, the data presented inconsistent results. This study was devised to investigate the association of Fas -1377 G/A polymorphism and cancer susceptibility in a large number of participants. METHODS The databases of PubMed, Embase, and Web of Science were searched and a total of 27 case-control studies including 13,355 cases and 16,078 controls were included in this meta-analysis. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the fixed-effects model. Statistical analyses were performed by using Stata software. RESULTS The results suggested that Fas -1377 G/A polymorphism was overall associated with cancer susceptibility (additive model: OR, 1.16, 95%CI = 1.06-1.27, Pheterogeneity = 0.381; recessive model: OR, 1.19, 95%CI = 1.10-1.29, Pheterogeneity= 0.137). In the subgroup analysis by cancer type, significantly increased risk was observed in breast cancer (additive model: OR, 1.24, 95%CI = 1.04-1.58, Pheterogeneity = 0.614; recessive model: OR, 1.24, 95%CI = 1.02-1.51, Pheterogeneity = 0.349) and lung cancer (recessive model: OR, 1.25, 95%CI = 1.04-1.49, Pheterogeneity = 0.090). Similarly, elevated cancer risk associated with Fas -1377 G/A polymorphism was revealed in Asians. CONCLUSIONS The combined results suggest that Fas -1377 G/A polymorphism might modulate cancer susceptibility in an Asian-specific manner.

Abstract
Background Published studies investigating the association between genetic polymorphism -884C/T (rs763110) of the FAS ligand (FASL) promoter and cancer risk reported inconclusive results. To derive a more precise estimation of the relationship, we performed an updated meta-analysis of all eligible studies. Methodology/Principal Findings We carried out a meta-analysis, including 47 studies with 19,810 cases and 23,485 controls, to confirm a more conclusive association between the FASL rs763110 polymorphism and cancer susceptibility. Overall, significantly reduced cancer risk was associated with the variant -884T when all studies were pooled (TC vs. CC: OR = 0.83, 95%CI = 0.75–0.92; Pheterogeneity<0.001; TT+TC vs. CC: OR = 0.85, 95%CI = 0.77–0.94; Pheterogeneity<0.001). Stratified analysis revealed that there was a statistically reduced cancer risk in Asians (TC vs. CC: OR = 0.76, 95%CI = 0.67–0.87; Pheterogeneity<0.001; TT+TC vs. CC: OR = 0.79, 95%CI = 0.70–0.90; Pheterogeneity<0.001) and in patients with cancers of head and neck (TC vs. CC: OR = 0.87, 95%CI = 0.77–0.99; Pheterogeneity = 0.118; TT+TC vs. CC: OR = 0.88, 95%CI = 0.78–0.99; Pheterogeneity = 0.168) and ovarian cancer (TC vs. CC: OR = 0.67, 95%CI = 0.49–0.90; Pheterogeneity = 0.187; TT+TC vs. CC: OR = 0.64, 95%CI = 0.48–0.86; Pheterogeneity = 0.199). Meta-regression showed that ethnicity (p = 0.029) and genotyping method (p = 0.043) but not cancer types (p = 0.772), sample size (p = 0.518), or source of controls (p = 0.826) were the source of heterogeneity in heterozygote comparison. Conclusion Our results suggest that the FASL polymorphism rs763110 is associated with a significantly reduced risk of cancer, especially in Asian populations.

PLoS One 2013; 8:e73700.

Abstract
BACKGROUND AND OBJECTIVES Disruption of apoptosis has been implicated in carcinogenesis. Specifically, various single-nucleotide polymorphisms (SNPs) in apoptotic genes, such as FAS-1377 G/A SNP, have been associated with cancer risk. FAS-1377 G/A SNP has been shown to alter FAS gene promoter transcriptional activity. Down-regulation of FAS and cell death resistance is key to many cancers, but an association between FAS-1377 G/A SNP and cancer risk is uncertain. Therefore, we conducted a meta-analysis of the current literature to clarify this relationship. METHODOLOGY/PRINCIPAL FINDINGS From PubMed and Chinese language (CNKI and WanFang) databases, we located articles published up to March 5, 2013, obtaining 44 case-control studies from 41 different articles containing 17,858 cases and 24,311 controls based on search criteria for cancer susceptibility related to the FAS gene -1377 G/A SNP. Odds ratios (ORs) and 95% confidence intervals (CI) revealed association strengths. Data show that the -1377 G allele was protective against cancer risk. Similar associations were detected in "source of control," ethnicity and cancer type subgroups. Lower cancer risk was found in both smokers with a GG+GA genotype and in non-smokers with the GG+GA genotype, when compared to smokers and nonsmokers with the AA genotype. Males carrying the -1377G allele (GG+GA) had lower cancer incidence than those with the AA genotype. Individuals who carried both FAS-1377(GG+GA)/FASL-844(TT+TC) genotypes appeared to have lower risk of cancer than those who carried both FAS-1377 AA/FASL-844 CC genotypes. CONCLUSIONS/SIGNIFICANCE The FAS-1377 G/A SNP may decrease cancer risk. Studies with larger samples to study gene-environment interactions are warranted to understand the role of FAS gene polymorphisms, especially -1377 G/A SNP, in cancer risk.

Abstract
We assessed FAS and FAS-L gene polymorphisms and messenger RNA (mRNA) levels in patients with recurrent pregnancy loss (RPL). This case-control study compared 129 women with RPL with 235 healthy multiparous women (control group). Genomic DNA and total mRNA were extracted from whole blood, and polymorphisms genotyping was performed by polymerase chain reaction (PCR). Messenger RNA expression levels were analyzed by real-time PCR. Data were analyzed by chi-square and Fisher exact tests; P < .05 was considered significant. There were no significant differences in the FAS (670 A/G) genotype or allelic frequencies between the RPL and control groups. We found significant differences in the FAS-L (844 C/T) genotype and allelic frequencies between women with RPL and controls. Patients with RPL had significantly higher FAS-L expression. Our data suggest that FAS-L gene polymorphism is associated with increased susceptibility to RPL. Moreover, women with RPL seem to abnormally express FAS-FAS-L molecules.

Abstract
To investigate the associations between Fas and FasL gene polymorphisms and susceptibility to knee osteoarthritis. Genomic DNA was obtained from 146 patients with knee osteoarthritis and 102 healthy controls. Genotype distributions and allelic frequencies of four polymorphisms of Fas (-670 G>A rs1800682, -1377 G>A rs2234767) and FasL (IVS2nt-124 A>G rs5030772, -844 T>C rs763110) genes were compared between the groups. Thereafter, this association was investigated between patients and controls of the same sex. There were significant differences between patients with knee osteoarthritis and controls regarding the genotype distributions and allelic frequencies of Fas-1377 G>A polymorphism (P = 0.0001 and P = 0.005, respectively). The Fas-1377 GG genotype and G allele were significantly more frequent in patients with knee osteoarthritis than in controls. Genotype distributions and allelic frequencies of Fas-670 G>A, FasL-844 T>C, and FasL IVS2nt-124 A>G polymorphisms did not differ between the groups (P > 0.05). However, there were no significant differences between patients and controls of the same sex (P > 0.05). These findings suggest that the Fas-1377 G>A polymorphism in the Fas gene related with apoptosis may contribute to susceptibility to knee osteoarthritis in the Turkish population. There is a need for further studies to evaluate the role of apoptosis in large cohorts.

Abstract
Genetic polymorphisms in the promoter regions of FAS, FASL and CASP8 involved in the apoptotic signaling pathway are thought to be associated with susceptibility to cancer. We hypothesized that these functional genetic variants might be associated with the risk of childhood acute lymphoblastic leukemia (ALL). A case-control study in a Chinese population with 361 cases of ALL and 519 controls was performed to evaluate the association between FAS, FASL and CASP8 variants and risk of childhood ALL. Individuals with FAS - 1377AG had an odds ratio (OR) of 0.72 for the risk of ALL compared to - 1377GG and the variant FASL - 844CC was associated with a statistically significantly decreased risk of childhood ALL (OR = 0.38). Furthermore, combined genotypes with 5-8 protective alleles were associated with a significantly decreased risk of childhood ALL compared with those with 0-4 variants, and this decreased risk was more pronounced among the subgroups of age < 6 years, female, parental never-drinking status and never house-painting. Our results provide evidence that FAS-FASL-CASP8 polymorphisms contributed to a reduced risk of childhood ALL in our population. Larger studies are warranted to validate our findings.

Abstract
BACKGROUND Apoptosis is the physiological mechanism of programmed cell death and abnormal regulation of this pathway can lead to carcinogenesis. We hypothesized that the FAS -1377G>A, -670A>G, and FASL -844T>C polymorphisms are associated with risk of prostate cancer (PCa). MATERIALS AND METHODS We genotyped polymorphisms in a hospital-based case-control study of 602 patients diagnosed with PCa and 703 cancer-free controls in a Chinese population using polymerase chain reaction-restriction fragment length polymorphism method. RESULTS We found a significantly decreased risk associated with FAS -1377GA [adjusted odds ratio (OR) = 0.71, 95% confidence interval (CI) = 0.56-0.90] genotype compared with the -1377GG genotype and decreased risk associated with FAS -670AG and -670GG genotypes (OR 0.75, 95% CI: 0.59-0.95; OR 0.70, 95% CI: 0.50-0.96) compared with the -670AA genotype. Consistently, we found that individuals carrying haplotype genotype with 0 or 1 risk allele (-1377G and -670A) had a lower risk of PCa than those with two risk alleles (OR 0.48, 95% CI: 0.28-0.80; OR 0.60, 95% CI: 0.41-0.87; OR 0.82, 95% CI: 0.69-0.97 for the AA, GG, and AG haplotype, respectively). In addition, when we evaluated these two FAS polymorphisms together, we found that the combined genotype with 4 risk alleles was associated with a significantly increased risk of PCa compared with those with 0-3 variants (OR 1.51, 95% CI: 1.19-1.91), and this increased risk was more pronounced among subgroups of Gleason score <7 and >7, and PSA > 20 ng/ml (OR 1.49, 95% CI: 1.08-2.04; OR 1.72, 95% CI: 1.25-2.44; OR 1.61, 95% CI: 1.23-2.13, respectively). CONCLUSIONS These results suggested that the FAS polymorphisms may contribute to PCa risk in a Chinese population.

Abstract
FAS (TNF receptor superfamily member 6, also known as CD95) plays a major role in T-cell apoptosis and is often dysregulated in CTCL. We searched for structural alterations of the FAS gene with the potential to affect its function. Although several heterozygous FAS promoter single nucleotide polymorphisms (SNPs) were detected, the only homozygous one was the -671 GG SNP present in 24/80 CTCL cases (30%). This SNP maps to an interferon response element activated by STAT-1. EMSA and supershift EMSA showed decreased CTCL nuclear protein/STAT-1 binding to oligonucleotides bearing this SNP. Luciferase reporters showed significantly less interferon-alfa responsive expression by FAS promoter constructs containing this SNP in multiple CTCL lines. Finally, FAS was upregulated by interferon-alfa in wildtype CTCL cells but not those bearing the -671 GG SNP. These findings indicate that many CTCL patients harbor the homozygous FAS promoter -671 GG SNP capable of blunting its response to interferon. This may have implications for CTCL pathogenesis, racial incidence and the response of patients to interferon-alfa therapy. In contrast, functionally significant mutations in FAS coding sequences were detected uncommonly. Among CTCL lines with the potential to serve as models of FAS regulation, FAS-high MyLa had both FAS alleles, FAS-low HH was FAS-hemizygous and FAS-negative SeAx was FAS-null.

Abstract
BACKGROUND AND AIM The FAS and FASL system play an important role in regulating apoptotic cell death. This study was designed to investigate the correlation of FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms with susceptibility to gastric cardiac adenocarcinoma in a population of a high-incidence region of Hebei Province. METHODS FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis in 262 gastric cardiac carcinoma (GCA) patients and 524 healthy controls. RESULTS Family history of upper gastrointestinal cancer (UGIC) might increase the risk of developing GCA (age- and sex-adjusted odds ratio [OR] = 1.38, 95% confidence interval [CI] = 1.02-1.86). The overall allelotype and genotype distributions of FAS-1377 G/A, and FASL-844 T/C polymorphisms in GCA patients did not significantly differ from that in healthy controls (P > 0.05). Compared with individuals with a FAS-670 A/A genotype, individuals with an A/G genotype in a smoker group had a lower risk of developing GCA (age, sex, and family history of UGIC adjusted OR = 0.55, 95% CI = 0.34-0.88). When the genotypes of FAS and FASL single nucleotide polymorphisms (SNP) were combined to analyze, no significant correlation was found between these SNP and the risk for GCA development. CONCLUSION In the high-incidence region of Hebei Province, FAS-1377 G/A and FASL-844 T/C polymorphisms were not associated with the risk of GCA. However, the FAS-670 A/G genotype might decrease the risk of GCA for smoker individuals.

Abstract
The FAS and FAS ligand (FASLG) system plays a key role in regulating apoptotic cell death, and corruption of this signaling pathway has been shown to participate in tumorigenesis. Functional promoter polymorphisms of the FAS and FASLG genes can alter transcriptional activities and thus alter risk of cancer. We hypothesized that the FAS -1377G>A, FAS -670A>G, and FASLG -844T>C polymorphisms in the promoter regions are associated with risk of gastric cancer. In a population-based case-control study of 332 gastric cancer cases and 324 controls, we genotyped these three polymorphisms and evaluated their association with risk of gastric cancer. We found that the FAS and FASL genotypes and the FAS haplotypes had no significant associations with risk of gastric cancer. In addition, there was no significant interaction between the FAS and FASL polymorphisms in the development of gastric cancer. The FAS and FASLG polymorphisms may not contribute to risk of gastric cancer in the southern Chinese population.

Abstract
Many studies have reported the association between the FASLG -844T/C polymorphism and cancer risk, but the data are remaining controversial. A pooled analysis was performed to assess this relationship comprehensively. Medline, PubMed, Embase and Web of Science were searched, and data were extracted and cross-checked independently by three authors. A total of 18 published studies including 22389 subjects were involved in this analysis. Overall, the -844C allele was associated with a significantly increased cancer risk (for CC versus TT: OR=1.23, 95% confidence interval (CI)=1.04-1.45; for CC+TC versus TT: OR=1.15, 95% CI=1.01-1.30; for CC versus TT+TC: OR=1.20, 95% CI=1.05-1.38). In the subgroup analysis by ethnicity, significantly elevated risks were found among Asians (for CC versus TT: OR=1.61, 95% CI=1.37-1.89; for CC+TC versus TT: OR=1.36, 95% CI=1.16-1.60; for CC versus TT+TC: OR=1.44, 95% CI=1.22-1.70). In the subgroup analysis by study design, significantly increased risks were found among population-based case-control studies (for CC versus TT: OR=1.40, 95% CI=1.06-1.84; for CC+TC versus TT: OR=1.25, 95% CI=1.01-1.55; for CC versus TT+TC: OR=1.31, 95% CI=1.06-1.61). These findings indicate that the FASLG -844C allele is emerging as a low-penetrant cancer susceptibility allele for cancer development. However, more comprehensive understanding of the association would certainly have an immense prospect in the promising field of individualised preventive care.

Abstract
The potentially functional polymorphism, rs763110 (-844C>T), in the promoter region of the FAS ligand (FASL) gene, has been implicated in cancer risk, but individually published studies show inconclusive results. To derive a more precise estimation of the association between the FASL rs763110 and risk of cancer, we performed a meta-analysis of 19 published studies that included 11,105 cancer cases and 11,372 controls. We used odds ratios (ORs) and 95% confidence intervals (CIs) to assess the strength of the associations. Overall, the rs763110 CT and TT variant genotypes were associated with a significantly reduced cancer risk of all cancer types in different genetic models (homozygote comparison: OR=0.80, 95% CI: 0.68-0.95, P(heterogeneity)=0.001; heterozygote comparison: OR=0.82, 95% CI: 0.72-0.95, P(heterogeneity)<0.001; dominant model comparison: OR=0.82, 95% CI: 0.71-0.94, P(heterogeneity)<0.001; and recessive model comparison: OR=0.88, 95% CI: 0.81-0.96, P(heterogeneity)=0.074). In the stratified analyses, the risk remained for studies of the smoking-related cancers and Asian populations, or population-based studies in all the genetic models. Although some modest bias could not be eliminated, this meta-analysis suggests that the FASL rs763110 T allele has a possible protective effect on cancer risk.

Abstract
Published data on the association between FAS -1,377 G/A polymorphism and cancer risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. A total of 17 studies including 10,564 cases and 12,075 controls were involved in this meta-analysis. Overall, significantly elevated cancer risk was associated with AA variant genotype when all the eligible studies were pooled into the meta-analysis (for AA vs GG: OR = 1.19; 95% CI = 1.01-1.40; P (heterogeneity) = 0.05; for recessive model: OR = 1.21; 95% CI = 1.04-1.41; P (heterogeneity) = 0.05). In the subgroup analysis by ethnicity, borderline statistically significantly increased risks were found among Asians for recessive model (OR = 1.20; 95% CI = 1.00-1.45; P (heterogeneity) = 0.01). In the subgroup analysis by population-based controls or hospital-based controls, statistically significantly increased risks were found among groups with population-based controls for AA versus GG (OR = 1.27; 95% CI = 1.02-1.58; P (heterogeneity) = 0.05) and recessive model (OR = 1.25; 95% CI = 1.00-1.59; P (heterogeneity) = 0.01). For breast cancer, borderline statistically significantly increased risks were found for AA versus GG (OR = 1.29; 95% CI = 1.00-1.67; P (heterogeneity) = 0.41). In summary, this meta-analysis suggests that the FAS -1,377 G/A polymorphism is associated with cancer susceptibility.

Abstract
Caspase-8 (CASP8) and caspase-10 (CASP10) play key roles in regulating apoptosis, and their functional polymorphisms may alter apoptosis and cancer risk. However, no reported studies have investigated the association between such polymorphisms and the risk of cutaneous melanoma (CM). In a hospital-based study of 805 non-Hispanic white patients with CM and 835 cancer-free age-, sex-, and ethnicity-matched controls, we genotyped three reported putatively functional polymorphisms of CASP8 and CASP10-CASP8 D302 H (rs1045485:G>C), CASP8 -652 6N del (rs3834129:-/CTTACT), and CASP10 I522L (rs13006529:A>T)-and assessed their associations with risk of CM and interactions with known risk factors for CM. We also calculated the false-positive report probability (FPRP) for significant findings. CASP8 302 H variant genotypes (DH: adjusted odds ratio [OR], 0.70; 95% confidence interval [CI], 0.50-0.98; DH+HH: unadjusted OR, 0.78; 95% CI, 0.62-0.98; FPRP, 0.79) and CASP8 -652 6N del variant genotypes (ins/del: OR, 0.74; 95% CI, 0.57-0.97; ins/del+del/del: OR, 0.76; 95% CI, 0.61-0.95; FPRP, 0.61) were associated with significantly lower CM risk than were the DD and ins/ins genotypes, respectively. However, the CASP10 522L variant genotypes were not associated with significantly altered CM risk. Also, the D-del-I haplotype was associated with a significantly lower CM risk (OR, 0.52; 95% CI, 0.37-0.74; FPRP, 0.04) than was the most common haplotype, D-ins-I. Furthermore, multivariate logistic regression analysis revealed that CASP8 D302 H, CASP8 -652 6N del, and CASP10 I522L were independent risk factors for CM. Therefore, these CASP8 and CASP10 polymorphisms may be biomarkers for susceptibility to CM.

Abstract
Apoptosis is important for targeting cancer cells for destruction. Various single-nucleotide polymorphisms (SNPs) in apoptotic genes have been associated with increased risks in lung cancer, particularly FAS -1377 G>A (rs2234767), FASLG -844 C>T (rs763110), IL1B +3954 C>T Phe105Phe (rs1143634) and BAT3 Ser625Pro (rs1052486). We studied the association of these SNPs with non-small cell lung cancer (NSCLC) in a large case-control study (N = 4263: 2644 cases and 1619 controls). No associations with NSCLC were observed in the main effects analysis for all four SNPs, adjusting for age, gender, smoking status, pack-years and years since smoking cessation. In subjects under age 60, for FASLG -844 C>T polymorphism, CT compared with the CC genotype, was significantly associated with increased risk of NSCLC, adjusted odds ratio (aOR) = 1.58 (1.22, 2.05), P = 0.0006 and TT aOR = 1.45 (1.01, 2.04), P = 0.04. In contrast, for those over age 60, the CT aOR = 0.91 (0.73, 1.13), P = 0.37 and TT aOR = 0.86 (0.64, 1.16), P = 0.32. The P-value for the age-genotype interaction was 0.004. For the IL1B +3954 C>T polymorphism, compared with the CC genotype, TT showed significant associations in former smokers and in men but tests of interaction were not significant (P(smoking) = 0.24, P(gender) = 0.17). No interactions were observed for FAS -1377 G>A and BAT3 Ser625Pro polymorphisms. Our findings indicate that age and smoking may modify the association of the FASLG -844 and IL1B + 3954 SNPs with the risk of NSCLC.

Abstract
The FAS/FASLG system plays a key role in regulating apoptosis. Previous findings have shown that CD4-dependent destruction of melanocytes is partially inhibited by blocking FAS-FASLG interactions in autoimmune vitiligo. Functional polymorphisms of the FAS and FASLG genes can alter their transcriptional activities. In a hospital-based case-control study of 750 vitiligo patients and 756 controls, we genotyped the FAS-1377 G>A, FAS-670 A>G, and FASLG-844 T>C polymorphisms and assessed their association with the risk of vitiligo. We found that a significantly increased risk of vitiligo was associated with the FAS-1377 AA genotype (adjusted odds ratio (OR), 1.49; 95% confidence interval (CI), 1.07-2.08) and the FAS-1377 AG genotype (adjusted OR, 1.31; 95% CI, 1.05-1.63) when compared with the FAS-1377 GG genotype. However, no evident risk was associated with FAS-670 G>A genotypes. In the combined analysis of the two variant alleles of FAS, genotypes with 3 to 4 risk alleles were associated with an increased risk of vitiligo compared with those having 0-2 variants (adjusted OR, 2.87; 95% CI, 1.90-4.32). In conclusion, genetic variants in the FAS gene may affect the risk of vitiligo in Chinese populations.

Abstract
Abstract
Purpose: Fas-Fas ligand (FasL)–mediated death pathway is important in the life and death of immune cells and, therefore, influences immune surveillance of carcinogenesis. This study examined the association between functional variants of Fas (−1377G→A and −670A→G), FasL (−844T→C), and caspase-8 (CASP8) six-nucleotide deletion polymorphism (−652 6N ins→del) and risk of pancreatic cancer.
Experimental Design: Genotypes were determined in 397 cases with pancreatic cancer and 907 controls. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated by logistic regression, and all statistical tests were two sided.
Results: We found a significant decrease in risk of pancreatic cancer associated with FasL and CASP8 but not Fas polymorphisms. Compared with noncarriers, the ORs of developing pancreatic cancer for FasL −844CT and TT carriers were 0.73 (95% CI, 0.57-0.94) and 0.35 (95% CI, 0.19-0.63), and for CASP8 −652 6N ins/del and del/del carriers were 0.65 (95% CI, 0.50-0.85) and 0.56 (95% CI, 0.33-0.98), respectively. Gene-gene interaction between the FasL and CASP8 variants further reduced the cancer risk in a multiplicative manner (OR for the presence of both FasL −844TT and CASP8 −652 6N del/del genotype, 0.10; 95% CI, 0.01-0.75). On the other hand, a multiplicative joint effect between the FasL −844CC or CASP8 −652 6N ins/ins genotype and smoking or diabetes mellitus in intensifying risk of pancreatic cancer was also evident.
Conclusions: These results suggest that genetic variations in the death pathway genes FasL and CASP8 are involved in susceptibility to developing pancreatic cancer.

Abstract
In a hospital-based case-control study of 805 non-Hispanic whites with cutaneous melanoma and 841 cancer-free age-, sex- and ethnicity-matched control subjects, 3 VDR polymorphisms (i.e., TaqI, BsmI and FokI) were genotyped using blood samples collected between 1994 and 2006. We tested the hypothesis that the haplotypes and combined genotypes of these polymorphisms were associated with melanoma risk by interacting with known risk factors. Haplotypes t-B-F (adjusted odds ratio [OR], 0.52; 95% confidence interval [CI], 0.34-0.80) and t-B-f (adjusted OR, 0.51; CI, 0.27-0.94) were associated with a reduced risk when compared to T-b-f. The combined genotypes Tt+tt/Bb+BB/Ff+ff (adjusted OR, 0.69; CI, 0.52, 0.90) and Tt+tt/Bb+BB/FF (adjusted OR, 0.58; CI, 0.43, 0.78) were also associated with reduced risk, whereas the combined genotype TT/Bb+BB/Ff+ff genotype (adjusted OR, 2.35; CI, 1.13, 4.98) was associated with increased risk when compared to TT/bb/Ff+ff genotypes. On multivariate analysis, only the TaqI polymorphism was an independent risk factor, while the FokI polymorphism interacted with skin color (p = 0.029), moles (p = 0.017) and first-degree relatives with any cancer (p = 0.013) in modifying risk. Together, these findings suggest that VDR polymorphisms may directly affect or modify the risk associated with known melanoma risk factors. Larger, population-based studies are needed to replicate our findings.

Abstract
Defective apoptosis signaling by the Fas pathway has carcinogenic implications. We analyzed 123 pediatric patients with osteosarcoma for Fas single nucleotide polymorphisms: 2 of the promoter region (-1377 G>A and -670 A>G) and 2 of the coding region (exon 3 18272 A>G and exon 7 22628 C>T). As a comparison group, we used 510 adults without a history of cancer. We found an increased risk of osteosarcoma associated with the heterozygous genotype Fas exon 3 AG (genotype frequency 19.5% in cases vs. 12.0% in controls, P=0.028; adjusted odds ratio=1.6, 95% confidence interval=0.9-2.7], and this association was more pronounced in non-Hispanic whites (20.6% in cases vs. 10.1% in controls, P=0.014; adjusted odds ratio=2.3, 95% confidence interval=1.2-4.6). Additionally, the frequency of the variant allele (exon 3 G) was significantly higher in cases than in controls for both the entire group and non-Hispanic whites (P=0.046 and P=0.030, respectively). We found no significant association between osteosarcoma risk and the other Fas polymorphisms. This study suggests an association between the Fas exon 3 A>G polymorphism and osteosarcoma risk; however, further study is needed with pediatric controls and a larger sample size.

Abstract
The role of FAS polymorphisms in prostate cancer has not been studied. Using the PCR-based restriction fragment-length polymorphism methodology, we evaluated FAS gene locus -670 genotypes in DNA from 904 men: 657 prostate cancer patients and 247 healthy controls. We found that carriers of AG or GG genotypes have a statistically significant protection (odds ratio (OR)=0.30; confidence interval (CI): 0.20-0.44 and OR=0.22; CI: 0.12-0.74, respectively) for disease with extra-capsular invasion. Taken together, a 72% protection was found for G allele carriers (OR=0.28; CI: 0.19-0.41). Fas exist as membrane-bound and soluble forms and with opposite roles. They derive from the same gene by alternative splicing. Membrane Fas receptors trigger apoptosis whereas, on the other hand, soluble Fas (sFas) bind to Fas ligand antagonizing Fas-Fas ligand apoptotic pathway. Our results suggest that G allele may reduce sFas levels preventing the apoptotic inhibition caused by the soluble form.

Abstract
BACKGROUND Nitric oxide (NO) is a multifunctional molecule that is produced by both neuronal NO synthase (nNOS) and inducible NO synthase (iNOS), and the expression of nNOS and iNOS is up-regulated in various cancer cells, including cutaneous melanoma (CM). The authors hypothesized that selected functional single-nucleotide polymorphisms (SNPs) in the nNOS and iNOS genes are associated with the risk of CM. METHODS In a hospital-based case-control study of 602 non-Hispanic white patients with CM and 603 matched, cancer-free controls, the authors genotyped the nNOS -84 guanine-to-adenine (G-->A), nNOS 276 cytosine-to-thymine (C-->T), iNOS Ex16+14C-->T, and iNOS 974G-->T SNPs and assessed their associations with the risk of CM in multivariate logistic regression models. RESULTS A significantly increased risk of CM was associated with the nNOS -84G-->A (adjusted odds ratio [OR], 1.49; 95% confidence interval [95% CI], 1.05-2.13) and -84AG+AA (OR, 1.48; 95% CI, 1.06-2.06) genotypes compared with the nNOS -84GG genotype, but not with other nNOS or iNOS SNPs. In a combined analysis, an increased risk of CM was associated with the nNOS -84AA+AG/276CT+TT genotype (OR, 1.70; 95% CI, 1.05-2.76) and the nNOS -84AA+AG/276CC genotype (OR, 1.70; 95% CI, 1.08-2.68) compared with the nNOS -84GG/276CT+TT genotypes. No altered risk of CM was associated with iNOS genotypes. In addition, there was statistical evidence of interaction of nNOS SNPs with having moles (P = .002) and sunburns (P = .017). CONCLUSIONS Genetic variants of nNOS, but not iNOS, may be biomarkers for susceptibility to CM, and the risk of CM associated with sunburns and moles may be modulated by nNOS variant genotypes.

Abstract
Sunlight causes DNA damage, including bulky lesions that are removed effectively by the nucleotide-excision repair (NER) pathway. There are at least eight core NER proteins participating in the pathway, and genetic variations in their genes may alter NER functions. We hypothesized that some NER variants are associated with risk of cutaneous melanoma. In a hospital-based case-control study of 602 non-Hispanic White patients with cutaneous melanoma and 603 age- and sex-matched cancer-free controls, we genotyped five common non-synonymous single-nucleotide polymorphisms identified to date and assessed their associations with risk of cutaneous melanoma. We found that a significantly increased risk of cutaneous melanoma was associated with XPD 751Lys/Gln [adjusted odds ratio (OR), 1.55 and 95% confidence interval (95% CI), 1.12-2.16] and XPD 751Gln/Gln (OR, 1.66; 95% CI, 1.03-2.68) genotypes compared with the XPD 751Lys/Lys genotype as well as XPD312Asp/Asn (OR, 1.54; 95% CI, 1.11-2.12) and XPD312Asn/Asn (OR, 1.75; 95% CI, 1.05-2.90) genotypes compared with the XPD 312Asp/Asp genotype. This increased risk was not observed in the other three XPC and XPG single-nucleotide polymorphisms. Moreover, the number of the observed XPD at-risk genotypes (i.e., 312Asn/Asn+Asn/Asp and 751Gln/Gln+Lys/Gln) was associated with cutaneous melanoma risk in a dose-response manner (OR, 1.47; 95% CI, 0.97-2.23 for one at-risk genotype; OR, 1.83; 95% CI, 1.29-2.61 for two at-risk genotypes; P(trend) < 0.001). However, we found no evidence of any interaction between XPD genotypes with XPC and XPG genotypes or the known risk factors. We concluded that genetic variants of the XPD gene might serve as biomarkers for susceptibility to cutaneous melanoma.
