چکیده

The purpose of this study was to evaluate the role of XPD genotypes as genetic indicator of susceptibility to ovarian cancer. We have used a case-control study. We analysed DNA samples from 141 ovarian cancer patients and 202 control subjects, for three XPD polymorphisms using PCR-RFLP. We observed that Asn312Asn XPD genotype carriers have increased susceptibility of ovarian cancer (OR=2.46 95% CI 1.20-5.06; P=0.015). Furthermore, we found that carriers of Gln751Gln XPD genotype have an increased susceptibility of ovarian cancer (OR=3.40 95% CI 1.61-7.15; P=0.001). Asn312Asn and Gln751Gln are particularly associated with an early-stage of disease. Our results suggest an important role for Asn312Asn and Gln751Gln XPD polymorphisms in the susceptibility to ovarian cancer.

Allele and Genotype Distributions of DNA Repair Gene Polymorphisms in South Indian Healthy Population

Various DNA repair pathways protect the structural and chemical integrity of the human genome from environmental and endogenous threats. Polymorphisms of genes encoding the proteins involved in DNA repair have been found to be associated with cancer risk and chemotherapeutic response. In this study, we aim to establish the normative frequencies of DNA repair genes in South Indian healthy popula...

XPG Gene Polymorphisms Contribute to Colorectal Cancer Susceptibility: A Two-Stage Case-Control Study

Previous studies have reported that xeroderma pigmentosum group G (XPG) gene polymorphisms may modulate colorectal cancer (CRC) susceptibility. In this study, we performed a two-stage case-control study to comprehensively investigate the associations of five polymorphisms in the XPG gene with CRC risk in 1,901 cases and 1,976 controls from Southern China, including rs2094258 C>T, rs751402 C>T, ...

XRCC3 and XPD/ERCC2 single nucleotide polymorphisms and the risk of cancer: a HuGE review.

Hundreds of polymorphisms in DNA repair genes have been identified; however, for many of these polymorphisms, the impact on repair phenotype and cancer susceptibility remains uncertain. In this review, the authors focused on the x-ray repair cross-complementing protein group 3 (XRCC3) and xeroderma pigmentosum group D (XPD)/excision repair cross-complementing rodent repair deficiency (ERCC2) ge...

BACKGROUND Published data regarding the association between xeroderma pigmentosum group D (XPD) Lys751Gln and Asp312Asn polymorphisms and gastric cancer susceptibility havew been inconclusive. This meta-analysis was therefore performed toobtain a more precise estimation of any relationship. MATERIALS AND METHODS A comprehensive literature search was conducted to identify all case-control stud...

XPC 939A>C and 499C>T polymorphisms and skin cancer risk: a meta-analysis.

The xeroderma pigmentosum complementation group C gene (XPC) has been identified as important for repairing UV-related DNA damage. Some subtle changes in this gene may impair repair efficiency and influence susceptibility to human cancers, including skin cancer. Two polymorphisms in XPC, 939A>C (rs2228001) and 499C>T (rs2228000), are considered to have possible associations with the risk of ski...
