Abstract
BackgroundHuman Excision Repair Cross-Complementation Group 2 (ERCC2) proteins play a vital role in the nucleotide excision repair pathway through ATP-dependent helicase activity. Several studies found that polymorphisms in the ERCC2 gene are associated with susceptibility to different cancers, although the outcomes were confusing. ObjectiveAs a result, in this retrospective study, we investigated the relationship between genetic polymorphisms of the ERCC2 gene at codons 312 (rs1799793) and 751 (rs13181) and bladder cancer susceptibility in Bangladesh, as well as the disease's aggressiveness. MethodsGenetic polymorphisms of ERCC2 were assayed by the polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) method with 121 bladder cancer patients and 130 healthy controls. ResultsPatients who had the Gln/Gln polymorphism of ERCC2 at codon 751 (OR=3.27; 95% CI=1.19-8.67; p<0.05) and Asp/Asn at codon 312 (OR=2.14; 95% CI=1.03-4.29; p<0.05) were significantly associated with a higher risk of developing bladder cancer. Again, Gln/Gln polymorphisms in bladder cancer (p<0.05) were more likely to be present in individuals with cancer in the family. ConclusionsThis study reveals that susceptibility and bladder cancer aggressiveness are associated with polymorphisms at codon 751 and Asp/Asn at codon 312 of the ERCC2 gene.
