BACKGROUND X-ray cross-complementing group 1 (XRCC1) polymorphisms affect DNA repair capacity and may therefore be of importance in colorectal carcinogenesis. Alcohol consumption, an important risk factor for colorectal cancer, may induce carcinogenesis through DNA damage caused by the toxic effects of alcohol or its metabolites. Therefore, we examined the associations of XRCC1 Arg399Gln, Arg28...
Several polymorphisms in the DNA repair gene are thought to have significant effects on cancer risk. We investigated the association of polymorphisms in the DNA repair genes XRCC1 Arg399Gln, XRCC3 Thr241Met, XPD Lys751Gln, XPG Asp1104His, APE1 Asp148Glu, and HOGG1 Ser326Cys with endometriosis risk. Genotypes were determined by PCR-RFLP assays in 52 patients with endometriosis and 101 age-matche...
The genetic polymorphisms of X-ray repair cross complementing group 1 (XRCC1), X-ray repair cross complementing group 3 (XRCC3), and xeroderma pigmentosum complementation group D (XPD) repair genes may lead to genetic instability and leukemogenesis. The purpose of the study was to evaluate the association between XRCC1 Arg399Gln, Arg280His and Arg194Trp, XRCC3 Thr241Met, and XPD Lys751Gln polym...
The association between the polymorphisms in DNA repair enzymes: 8-oxoguanine glycosylase-1 (OGG1), AP endonuclease-1 (APE1), DNA polymerase β (POLβ), X-ray cross-complementing group 1 (XRCC1) in the base excision repair (BER) pathway and xeroderma pigmentosum complementation group D (XPD) genes in the nucleotide excision repair (NER) pathways and the risk of dilated cardiomyopathy (DCM) in the...
BACKGROUND Single nucleotide polymorphisms (SNPs) in DNA repair genes can alter gene expression and activity and affect response to cancer treatment and, correspondingly, survival. The present study was designed to evaluate the utility of the XRCC1 Arg399Gln and ERCC1 Cys8092Ala SNPs, measured in pretreatment biopsy samples, as predictors of response to radiotherapy in patients with non-metasta...
DNA repair plays an important role in maintaining the integrity of the genome by repairing DNA damage induced by carcinogens. Certain genetic polymorphisms that occur in DNA-repair genes may affect the ability to repair DNA defects, and may represent a risk factor in carcinogenesis. The gene XRCC1 is involved in DNA repair. The purpose of our study was to investigate the association between XRC...
BACKGROUND Head and neck cancer is a significant current health problem in Hungary because the mortality of this cancer has increased by 387% in the last thirty-two years. Because of the important role of the XRCC1 gene in DNA repair, we wanted to test the effects of the Arg194Trp and Arg399Gln polymorphisms of XRCC1 on the clinical outcome of head and neck cancer. PATIENTS AND METHODS A poly...
XRCC1, a protein directly involved in the repair of DNA base damage, contains at least three common polymorphisms. One of these, the codon 399 arg-->gln variant, has been associated with several cancer-related biomarkers, suggesting it may have functional significance in exposure-induced cancers. However, results from case-control studies have yielded conflicting results. We investigated the XR...
BACKGROUND Genetic polymorphisms of DNA repair enzymes may lead to genetic instability and colorectal cancer carcinogenesis. Our objective was to measure the interactions between polymorphisms of repair genes and tobacco smoking in colorectal cancer. METHODS The case-control study involved sixty-eight colorectal cancer patients and 121 non-cancer controls divided into non-smokers and smokers ...
