Abstract
Esophageal cancer (EC) is a very aggressive tumor, and no reliable prognostic markers exist especially for resectable advanced neoplasia. The principal aim of this study was to investigate the association of germline polymorphisms in nucleotide excision repair (NER) pathway genes with the overall survival (OS) of patients with advanced EC. As a second aim, we also studied the association of NER gene variants with response to cisplatin-based chemotherapy. Among the EC patients referred to our Institution between 2004 and 2012, we selected a cohort of 180 patients diagnosed with a clinical tumor stage ranging from IIB and IVA. Patients were genotyped for four NER variants, two in the ERCC1 (rs11615 and rs3212986) and two in the ERCC2/XPD (rs1799793 and rs13181) genes. Kaplan–Meier analyses and Cox proportional hazards model were used to evaluate the associations of the selected variants with OS; association with response to neoadjuvant therapy was investigated using logistic regression. Results showed that the ERCC1 rs3212986 and the ERCC2/XPD rs1799793 were significantly associated with shorter OS. On the contrary, response association analysis displayed that, while rs11615 and rs3212986 in ERCC1 were associated with response, both ERCC2/XPD variants were not. By creating survival prediction models, we showed that the rs3212986 and the rs1799793 have a better predictability of the tumor stage alone. Furthermore, they were able to improve the power of the clinical model (AUC = 0.660 vs. AUC = 0.548, p = 0.004). In conclusion, our results indicate that the ERCC1 rs3212986 and the ERCC2/XPD rs1799793 could be used as surrogate markers for a better stratification of EC patients with advanced resectable tumor.

Abstract
AbstractWe investigated the effect of polymorphisms in four DNA repair genes, viz. RAD18 Arg302Gln (G>A) (rs373572), XPD Asp312Asn (G>A) (rs1799793), APE1 Asp148Glu (T>G) (rs3136820), and OGG1 Ser326Cys (C>G) (rs1052133) on the risk for type 2 diabetes mellitus (T2DM) and hypertension (HT) in association with smoking, tobacco chewing, and alcohol consumption in a population from Northeast India. The study subjects were comprised of 70 patients suffering from both T2DM and HT and 83 healthy controls. Genotyping was performed using ARMS-PCR for XPD Asp312Asn (G>A) and PCR-CTPP for RAD18 Arg302Gln (G>A), APE1 Asp148Glu (T>G) and OGG1 Ser326Cys (C>G). The RAD18 Gln/Gln genotype was found to significantly increase the risk for T2DM and HT by 30 fold. Significant high risk was observed for individuals with XPD Asn/Asn-RAD18 Arg/Gln genotypes. Smoking was found to be the single most important independent risk factor for T2DM and HT. This study concludes that RAD18 Arg302Gln and XPD Asp312Asn polymorphisms might increase the risk for T2DM and HT in association with smoking, tobacco chewing, and/or alcohol consumption, while APE1 Asp148Glu (T>G) and OGG1 Ser326Cys (C>G) polymorphisms do not contribute to such risk.

Abstract
Many studies have reported β-catenin involvement in the development of esophageal carcinoma (EC), but its prognostic significance for EC patients remains controversial. Therefore, we conducted this meta-analysis to explore the issue in detail. After searching PubMed, EMBASE, Web of Science, and Chinese Biomedical Literature Database, we included a total of ten relevant studies. We pooled the overall survival (OS) data using RevMan 5.2 software. The results showed that aberrant expression of β-catenin was associated with a significant increase of mortality risk (hazard ratio 1.71, 95%CI 1.46-2.01; p<0.00001). Subgroup analyses further suggested that aberrant expression of β-catenin resulted in poor OS of EC patients regardless of histological type of EC, study location or criteria for aberrant expression of β-catenin, and the sensitivity analyses revealed that the result was robust. The meta-analysis revealed that aberrant expression of β-catenin could be a predicative factor of poor prognosis for EC patients.

Abstract
This meta-analysis was performed to evaluate the association between xeroderma pigmentosum complementary group D (XPD) Lys751Gln and Asp312Asn polymorphisms and susceptibility to hepatocellular carcinoma (HCC). PubMed, Embase, Google Scholar and the Chinese National Knowledge Infrastructure and the Chinese Biomedicine databases were systematically searched to identify relevant studies published up to June 1, 2014. Statistical analyses were performed using Stata version 12.0 software. A total of 11 case-control studies, comprising 2,852 cases and 2,936 controls, were included. The results of the meta-analysis revealed that a significant association between the risk of HCC and variant genotypes of the XPD Lys751Gln and Asp312Asn polymorphisms was evident in the homozygote comparison [Gln/Gln versus Lys/Lys: Odds ratio (OR), 1.831; 95% confidence interval (CI), 1.001-3.349], heterozygote comparison (Lys/Gln versus Lys/Lys: OR, 1.486; 95% CI, 1.044-2.114), dominant model (Gln/Gln + Lys/Gln versus Lys/Lys: OR, 1.540; 95% CI, 1.054-2.249) and allelic contrast (Gln-allele versus Lys-allele: OR, 1.453; 95% CI, 1.032-2.046) for the Lys751Gln polymorphism and the homozygote comparison for the Asp312Asn polymorphism (Asn/Asn versus Asp/Asp: OR, 1.352; 95% CI, 1.010-1.808). By contrast, no significant association was observed in the recessive model for the Lys751Gln polymorphism (Gln/Gln versus Lys/Gln + Lys/Lys: OR, 1.603; 95% CI, 0.924-2.779), or for the heterozygote comparison (Asn/Asp versus Asp/Asp: OR, 1.229; 95% CI, 0.857-1.762), dominant model (Asn/Asn + Asp/Asn versus Asp/Asp: OR, 1.249; 95% CI, 0.910-1.715), recessive model (Asn/Asn versus Asp/Asn + Asp/Asp: OR, 1.250; 95% CI, 0.940-1.663) or allelic contrast (Asn-allele versus Asp-allele: OR, 1.226; 95% CI, 0.965-1.557) for the Asp312Asn polymorphism. The present meta-analysis has indicated that the XPD Lys751Gln polymorphism could be a potential biomarker of HCC susceptibility and that the XPD Lys751Gln and Asp312Asn polymorphisms could be risk factors for HCC susceptibility in an Asian population; however, further large-scale and well-designed studies are required to reach a more precise and comprehensive conclusion.

Abstract
Background Recent clinical studies have linked polymorphisms in the xeroderma pigmentosum group D (XPD) gene, a key repair gene involved in nucleotide excision repair, to increased risk of hepatocellular carcinoma (HCC). However, the cellular effects of XPD expression in cultured HCC cells remain largely uncharacterized. Therefore, the aim of this study was to characterize the in vitro cellular effects of XPD expression on the HCC cell line HepG2. Material/Methods HepG2 cells were transfected as follows to create four experimental groups: pEGFP-N2/XPD plasmid (XPD) group, EGFP-N2 plasmid (N2) control group, lipofectamine™ 2000 (lipid) control group, and non-transfected (CON) control group. An MTT cell proliferation assay, Annexin V-APC apoptosis assay, colony formation assay, scratch wound migration assay, Transwell migration assay, and Western blotting of the autophagic proteins LC3 and p62 were conducted. Results XPD expression significantly inhibited HepG2 cell proliferation (p<0.05), significantly promoted HepG2 cell apoptosis (p<0.05), significantly inhibited HepG2 colony formation (p<0.05), significantly decreased HepG2 cells’ migratory ability (p<0.05), and significantly lowered HepG2 cells’ invasive capacity (p<0.05). Western blotting showed that XPD expression significantly increased LC3 expression (p<0.05) and significantly reduced p62 expression (p<0.05). Conclusions XPD expression serves as a tumor suppressor and dysregulates autophagic protein degradation in HepG2 cells in vitro. Further in vivo pre-clinical studies and clinical trials are needed to validate XPD’s potential as a tumor-suppressive gene therapy.

Abstract
OBJECTIVES In this exploratory study, we aimed to investigate whether polymorphisms in excision repair cross-complementing group 1 (ERCC1) and excision repair cross-complementing group 2/xeroderma pigmentosum group D (ERCC2/XPD) in the nucleotide excision repair (NER) pathways associated with DNA adducts in human lung tissue. We also analyzed the association stratified by the major histologic subtypes of non-small cell lung cancer (NSCLC): adenocarcinoma (ADC) and squamous cell carcinoma (SQCC). METHODS The study population consisted of 107 early stage NSCLC patients from the Massachusetts General Hospital (MGH) in Boston who underwent curative surgical resection. Genotyping was completed for SNPs in ERCC1 [C8092A (rs3212986) and C118T (rs11615)] and ERCC2/XPD [Asp312Asn (rs1799793) and Lys751Gln (rs1052559)] using a PCR-RFLP method and the PCR with fluorescent allele-specific oligonucleotide probes (Taqman). DNA adduct levels were measured as relative adduct levels per 10(10) nucleotides by (32)P-postlabeling in non-tumor lung tissue. RESULTS After adjusting for potential confounders, lung DNA adduct levels increased by 103.2% [95% confidence interval (CI), -11.5 to 366.6] for ERCC2/XPD rs1799793AA genotype compared with their corresponding wild type homozygous genotypes in overall NSCLC, but the difference did not reach statistical significance. When we stratified by the subtypes of NSCLC, we found that DNA adducts levels in lung increased by 204.9% (95% CI, 0.8 to 822.2, P=0.059) for ERCC2/XPD rs1799793AA genotype in subjects with SQCC and the trend was statistically significant (P for trend=0.0489). CONCLUSIONS Polymorphisms in ERCC2/XPD Asp312Asn may be associated with increased DNA adduct levels in the lung, especially among subjects with SQCC. Further large scale studies are needed to confirm our findings.

Abstract
In the present study, we investigated the effect of the DNA repair gene polymorphisms XPD Asp312Asn (G>A), APE1 Asp148Glu (T>G), and MUTYH Tyr165Cys (G>A) on the risk for head and neck cancer (HNC) in association with tobacco use in a population of Northeast India. The study subjects comprised of 80 HNC patients and 92 healthy controls. Genotyping was performed using amplification refractory mutation system-PCR (ARMS-PCR) for XPD Asp312Asn (G>A) and PCR using confronting two-pair primers (PCR-CTPP) for APE1 Asp148Glu (T>G) and MUTYH Tyr165Cys (G>A). The XPD Asp/Asn genotype increased the risk for HNC by 2-fold (odds ratio, OR = 2.072; 95 % CI, 1.025-4.190; p < 0.05). Interaction between APE1 Asp/Asp and XPD Asp/Asn as well as MUTYH Tyr/Tyr and XPD Asp/Asn genotypes further increased the risk by 2.9 (OR = 2.97; 95 % CI, 1.16-7.61; p < 0.05) and 2.3 (OR = 2.37; 95 % CI, 1.11-5.10; p < 0.05) folds, respectively. The risk was further increased in heavy smokers with the XPD Asp/Asn genotype and heavy tobacco chewers with XPD Asn/Asn genotype by 7.7-fold (OR = 7.749; 95 % CI, 2.53-23.70; p < 0.05) and 10-fold (OR = 10; 95 % CI, 1.26-79.13; p < 0.05), respectively. We thus conclude that the XPD Asp312Asn and APE1 Asp148Glu polymorphisms increase the risk for HNC in association with smoking and/or tobacco chewing in the population under study.

Abstract
ERCC2 is an essential component of the nucleotide excision repair pathway which is involved in the effective maintenance of genome integrity. Association studies on ERCC2 polymorphisms and glioma risk have yielded inconclusive results. This meta-analysis was performed to gain a better insight into the relationship between ERCC2 polymorphisms and glioma risk. A systematic literature search updated to December 2, 2013 was performed in the Pubmed and EMBASE databases. Crude pooled odds ratios (ORs) with their corresponding 95% confidence intervals (95% CIs) were used to estimate the association between ERCC2 polymorphisms and glioma risk under a suitable effect model according to heterogeneity. All analyses were performed using Review Manager 5 (version 5.2) and STATA (version 12.0). The combined results demonstrated rs13181 to be significantly associated with glioma risk (G allele versus T allele: OR=1.15, 95% CI=1.05-1.26, P=0.002; dominant model: OR=1.22, 95% CI=1.07-1.39, P=0.002; recessive model: OR=1.18, 95% CI=0.98-1.41, P=0.070). We also found that rs13181 acts in an allele dose-dependent manner (GG versus TT: OR=1.30, 95% CI=1.07-1.57, P=0.009; TG versus TT: OR=1.20, 95%=CI 1.05-1.37, P=0.009; trend test, P=0.004). However, no evidence was found in analyses for the association between other 3 ERCC2 polymorphisms (rs238406, rs1799793, and rs1052555) and susceptibility to glioma development. Our meta-analysis suggests that rs13181 is significantly associated with glioma risk in an allele dose-dependent manner, whereas, 3 other ERCC2 polymorphisms (rs238406, rs1799793, and rs1052555) may have no influence.

Abstract
Esophageal squamous cell carcinoma (ESCC), one of the leading causes of cancer death worldwide, occurs at a relatively high frequency in China. To investigate whether common excision repair cross-complementing rodent repair group 2 (ERCC2) variants (rs3916874 G>C, rs238415 C>G, rs1618536 G>A, rs1799793 G>A, and rsl3181 A>C) were associated with ESCC risk, a case-control study was conducted, including 405 cases with ESCC and 405 age and sex 1:1 matched cancer-free controls. The result showed that rsl3181 AC/CC genotypes was associated with an increased risk of ESCC (OR: 1.45, 95% CI: 1.05-2.00), and two ERCC2 haplotypes Grs3916874Crs238415Grs1618536Grs1799793Crsl3181 (Hap5) and Grs3916874Grs238415Ars1618536Grs1799793Crsl3181 (Hap7) were associated with increased risk of ESCC (OR: 2.16, 95 % CI: 1.27-3.57 for Hap5 and OR: 3.72; 95 % CI: 1.89-6.63 for Hap7, respectively), while Grs3916874Grs238415Grs1618536Grs1799793Arsl3181 (Hap4) was associated with decreased risk of ESCC (OR: 0.47, 95% CI: 0.35-0.71). Gene-environment interaction analysis by multifactor dimensionality reduction (MDR) software showed that there was an interaction among rs238415, rs1618536, and family history of cancer with a P value under 0.0001 (OR: 3.23: 95% CI: 2.37-4.40). These results suggested that genetic variations in the ERCC2 gene were associated with risk of ESCC, and there was a significant interaction between gene polymorphisms and family history of cancer in the etiology of ESCC.

Abstract
The xeroderma pigmentosum group D (XPD) and human 8-oxoguanine glycosylase 1 (hOGG1) genes have been suggested to play an important role in the pathogenesis of hepatocellular carcinoma (HCC). However, the results have been inconsistent. In this study, we performed a meta-analysis to clarify the associations of polymorphisms of XPD and hOGG1 genes with HCC risk. Published literature from PubMed, EMBASE, and Chinese National Knowledge Infrastructure were retrieved. Pooled odds ratio (OR) with 95 % confidence interval (CI) was calculated using a fixed- or random-effects model. Seven studies (1,955 HCC cases and 2,023 controls) for XPD Lys751Gln polymorphism and six studies (1,470 HCC cases and 1,541 controls) for hOGG1 Ser326Cys polymorphism were included in the final meta-analysis. For XPD Lys751Gln polymorphism, no significant association was found under all genetic models (Gln/Gln vs Lys/Lys OR = 1.09, 95 % CI = 0.28-4.18; Gln/Lys vs Lys/Lys OR = 1.41, 95 % CI = 0.81-2.44; dominant model OR = 1.40, 95 % CI = 0.77-2.57; recessive model OR = 1.02, 95 % CI = 0.33-3.23). For hOGG1 Ser326Cys polymorphism, there was a significant association of this polymorphism with HCC risk under heterogeneous codominant model (OR = 1.38, 95 % CI = 1.01-1.88) and dominant model (OR = 1.57, 95 % CI = 1.14-2.16). The sensitivity analysis indicated that the significant association between hOGG1 Ser326Cys polymorphism and HCC risk was not robust. The present meta-analysis has limited evidence to support the association of XPD Lys751Gln and hOGG1 Ser326Cys polymorphisms with HCC risk. Further, large-scale studies with the consideration for gene-gene/gene-environment interactions should be conducted to investigate the association.
