AIM We conducted a case-control study in China to clarify the association between the XRCC1-Arg399Gln polymorphism and HCC risk. METHODS A total of 202 cases and 236 controls were selected from the the Affiliated Hospital of Qingdao University from May 2008 to May 2010. Assessment of the XRCC1-Arg399Gln polymorphism was based upon duplex polymerase-chain-reactions with the confronting-two-pai...

The excision repair cross-complementing rodent repair deficiency complementation group 1 (ERCC1), and X-ray repair cross-complementing group 1 (XRCC1) genes appear to protect mammalian cells from the harmful effects of ionizing radiation. We conducted a large case-control study to investigate the association of polymorphisms in ERCC1 C118T, ERCC1 C8092A, XRCC1 A194T, XRCC1 A194T, and XRCC3 C241...

The authors performed a systematic review and meta-analysis of associations of the x-ray repair crosscomplementing 1 gene (XRCC1) single nucleotide polymorphisms (SNPs) Arg194Trp, Arg280His, and Arg399Gln with gastric cancer risk, based on eligible studies retrieved from electronic databases for the period January 2000– December 2009. Ultimately, 12, 6, and 3 studies were found to be eligible f...

The study utilized molecular-genetic, cytogenetic, and statistical analyzes methods. A cytogenetic molecular genetic analysis of the inhabitants villages Amangeldy, Belbulak, in whose territory warehouses unused pesticides are located, was carried out. Residents Basshi village, on which there no products disposal pesticides, were taken as control. Cytogenetic showed a high level chromosomal abe...

background: x-ray repair cross-complementing group 1 (xrcc1) gene is a dna repair gene and its non-synonymous single nucleotide polymorphisms (snp) may influence dna repair capacity which has been considered as a modifying risk factor for cancer development. methods: a case-control study was conducted to investigate impact of three frequently studied polymorphisms (arg194trp, arg280his and arg3...

The aim of this paper is to analyse the role exerted by X-ray repair cross-complementing group 1 (XRCC1) genetic polymorphisms and haplotypes in increasing breast cancer risk and in modulating radiotherapy-induced adverse reactions. An Italian cohort of breast cancer patients and a matching group of healthy controls were genotyped for XRCC1-77T>C, Arg194Trp and Arg399Gln polymorphisms. Our data...

XRCC1 genetic polymorphisms could be associated with increased risk of various cancer, including hepatocellular carcinoma (HCC), the fifth most common cancer. We here conducted a study to explore the role of selective SNPs of the XRCC1 and XPD genes in the prognosis of HCC. A total of 231 cases were collected, and genotyping of XRCC1 Arg194Trp, XRCC1 Arg399Gln, XPD Lys751Gln and XPD Asp312Asn w...

AIM XRCC1 and XPD are two major repair genes involved in nucleotide excision repair (NER), which is reported to be associated with risk of several cancers. We explored the association of XRCC1 and XPD polymorphisms with the risk of HCC. METHODS A total of 410 cases with HCC and 410 health controls were collected. XRCC1 Arg194Trp, XRCC1 Arg399Gln, XPD Lys751Gln and XPD Asp312Asn genotyping was...

CONTEXT Known polymorphisms of DNA repair genes can be associated with the risk of many types of cancer. There is no consensus regarding association between XRCC1 and OGG1 with breast cancer (BC). OBJECTIVES The aim of this study is to collect relevant published studies systematically. DATA SOURCES Sixty-two publications were identified through searching PubMed, PubMed Central, ISI web of k...

Background: PCOS was reported to arise from the interaction of genetic and environmental factors. Some studies reported that women with PCOS have DNA damage and chromosome breakage. Such studies bring to mind the genes that are involved in DNA repairing. At present, several DNA repair genes and, as products of these genes, certain polymorphisms that alter the activity of proteins are known in t...
