Cellular DNA repair processes are crucial to maintain genome stability and integrity. In DNA base excision repair, a tight heterodimer complex formed by DNA polymerase β (Polβ) and XRCC1 is thought to facilitate repair by recruiting Polβ to DNA damage sites. Here we show that disruption of the complex does not impact DNA damage response or DNA repair. Instead, the heterodimer formation is requi...

Interindividual variation in prostate cancer (PCa) susceptibility may be modulated in part through genetic polymorphisms in the DNA repair genes, especially the genes involved in the base excision repair and nucleotide excision repair pathway. Two of the common single-nucleotide polymorphisms X-ray repair cross-complementing group 1 (XRCC1) and Xeroderma pigmentosum group D (XPD) genes in PCa, ...

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...

X-ray repair cross-complementing group 1 (XRCC1) is a major DNA repair gene involved in BER mutation. Polymorphisms in DNA repair genes associated with repair efficiency against DNA damage may predispose an individual׳s cancer susceptibility. Data from cervical cancer patients was collected from South Indian Women. Genotyping of XRCC1 polymorphisms (194C/T, 280G/A and 399G/A) was done by polyme...

Mutant p53 protein and anti-p53 antibody in circulating blood can be detectedamong individuals with mutations of the p53 tumor suppressor gene. Plasma mutant p53 protein and anti-p53 antibody have also been associated with vinyl chloride monomer (VCM) exposure, although the mechanism of VCM-related carcinogenesis remains unclear. Polymorphisms of metabolic and DNA repair genes have been implica...

X-ray repair cross complementing group 1(XRCC1) polymorphisms have been implicated in interindividual variability of efficacy of platinum chemotherapy for treating non-small cell lung cancer (NSCLC); however, results of different studies have been inconsistent. We conducted a meta-analysis to investigate the association between polymorphisms in the XRCC1 gene and response rate of platinum chemo...

BACKGROUND Many reports have shown inconsistent results on the relationship between single nucleotide polymorphisms (SNPs) of X-ray repair cross complementing protein (XRCC1) gene and platinum-based chemotherapeutic efficacy. This meta-analysis aimed to summarize published data about the association between two SNPs of XRCC1 (Arg194Trp and Arg399Gln) and treatment outcomes of patients with adva...

BACKGROUND To the authors' knowledge, few studies have been conducted to date regarding dietary selenium and the potential gene-nutrient interactions with single-nucleotide polymorphisms (SNPs) in different pathways on the risk of esophageal cancer. METHODS The authors investigated the role of dietary selenium intake and its interplay with SNPs of the ALDH2 (glutamic acid [Glu] 487 lysine [Ly...
