| Abstract | Genetic polymorphisms in DNA repair genes may be involved in increasing the risk of bladder cancer. Association studies on the excision repair cross-complementation group 2 (ERCC2) gene polymorphisms and bladder cancer risk have reported conflicting results. The aim of this meta-analysis of eligible cancer case-control studies is to investigate the role of ERCC2 SNPs (Arg156Arg, Asp312Asn, and Lys751Gln), gender and smoking in determining susceptibility to bladder cancer. A literature search was conducted in the PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar databases to indentify eligible studies published before December 1, 2013. We performed a meta-analysis of 23 case-control studies with a total of 7,062 bladder cancer patients and 8,832 controls. The overall analysis suggested that ERCC2 Arg156Arg, Asp312Asn, and Lys751Gln are associated with increased bladder cancer risk. For ERCC2 Arg156Arg, the mutant allele was associated with a 1.36-fold (95 % CI = 1.15–1.61) increased risk of bladder cancer. For ERCC2 Asp312Asn, individuals with the Asn allele were associated with a 1.29-fold (95 % CI = 1.13–1.48) increased risk of bladder cancer. For ERCC2 Lys751Gln, individuals who carried the variant heterozygote Lys/Gln or homozygote Gln/Gln had a significantly increased bladder cancer risk, compared with the wild genotype Lys/Lys (OR = 1.10, 95 % CI = 1.03–1.18). Furthermore, gender and smoking may modify the association between these SNPs and bladder cancer risk. This study provides the strongest evidence to date for the role of common variants of the ERCC2 gene in bladder carcinogenesis. Further studies comprehensively characterizing other DNA repair pathways and accounting for exposure to relevant environmental factors should offer further insight into the role of DNA repair in bladder cancer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
