Laryngeal cancer is the major malignant tumor affecting the upper respiratory tract. Previous studies have reported on the association between XRCC1 genetic polymorphisms and risk of laryngeal cancer, but with conflicting results. In this study, we attempted to assess the association between XRCC1 Arg194Trp, Arg280His and Arg399Gln polymorphisms and risk of laryngeal cancer in a Chinese populat...

BACKGROUND Polymorphisms in the human oxoguanine glycosylase 1 ( hOGG1 ) and X-ray repair cross-complementing 1 ( XRCC1 ) genes have been extensively studied in the association with various human cancers such as endometrial cancer. MATERIAL AND METHODS The genotype analysis of hOGG1 Ser326Cys and XRCC1 Arg399Gln gene polymorphisms for 150 endometrial cancer patients and 150 controls of cancer...

OBJECTIVE Coronary artery disease (CAD) is a life-threatening disease and is caused by various factors, with genetic variation being an important risk factor. The association between X-ray repair cross-complementing group 1 (XRCC1) polymorphisms and CAD has been extensively studied with conflicting results. We performed a meta-analysis to investigate the overall association between XRCC1 polymo...

We aimed to assess the role of polymorphisms of the XRCC1 Arg194Trp, XRCC1 Arg399Gln, ERCC5 His1104Asp, and ERCC5 His46His genes on clinical outcomes of advanced non-small cell lung cancer (NSCLC) patients receiving platinum-based chemotherapy regimens. A total of 378 NSCLC patients were asked to participate within 1 month after diagnosis between January 2005 and January 2006, and they were fol...

BACKGROUND In the X-ray repair cross-complementing group 1 (XRCC1) gene, a polymorphism, Arg399Gln (rs25487), has been shown to change neoconservative amino acid and thus result in alternation of DNA repair capacity. Numerous studies have investigated the association between Arg399Gln and breast cancer risk in the American population, but yielding inconsistent results. This study aimed to clari...

BACKGROUND The prevalence of lung cancer in China will be the world's highest if allowed to proceed uncurbed. To unravel its genetic underpinnings, we sought to investigate the association of three well-characterized nonsynonymous polymorphisms in XRCC1 (Arg194Trp and Arg399Gln) and XRCC3 (Thr241Met) genes with lung cancer risk in northeastern Chinese. METHODOLOGY/PRINCIPAL FINDINGS This stud...

Base excision repair pathway may play an important role in repairing DNA damage related to Helicobacter pylori-induced inflammatory process. To evaluate the association between genetic polymorphisms of X-ray repair cross-complementing group 1 (XRCC1, Arg194Trp and Arg399Gln), adenosine diphosphate ribosyl transferase (ADPRT, Val762Ala), 8-oxoguanine DNA glycosylase (OGG1, Ser326Cys) and apurini...

BACKGROUND X-ray repair cross-complementing group 1 (XRCC1) is one of the DNA repair genes encoding a scaffolding protein that participate in base excision repair (BER) pathway. However, studies on the association between polymorphisms in this gene and glioma have yielded conflicting results. This meta-analysis was performed to derive a more precise estimation between XRCC1 polymorphisms (Arg39...
