objective(s): coronary artery disease (cad) is the leading cause of death in both male and female worldwide. the main cause of cad is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. x-ray repair cross-complementing protein 1 (xrcc1) as a ...

among the lesions induced by chemotherapeutic drugs, dna double-strand breaks (dsb) are considered the most serious ones that can result in cell death, if it is not properly repaired. homologous recombination (hr) pathway is the main system for dsb repair and xrcc3 has a key role in this pathway. protein activity can be affected by the xrcc3 polymorphism. thus, in this study, the association be...

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...

X-ray repair cross complementary group gene is one of the most studied candidate gene involved in different types of cancers. Studies have shown that X-ray repair cross complementary genes are significantly associated with increased risk of breast cancer in females. Moreover, studies have revealed that X-ray repair cross complementary gene polymorphism significantly varies between and within di...

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...

The RAD54 gene has an essential role in the repair of double-strand breaks (DSBs) via homologous recombination in yeast as well as in higher eukaryotes. A Drosophila melanogaster strain deficient in the RAD54 homolog DmRAD54 is characterized by increased X-ray and methyl methanesulfonate (MMS) sensitivity. In addition, DmRAD54 is involved in the repair of DNA interstrand cross-links, as is show...

Inherited single nucleotide polymorphisms (SNPs) of DNA repair genes may contribute to variations in DNA repair capacity and susceptibility to cancer. We investigated the role of SNPs in three DNA repair genes (X-ray repair cross-complementing group 1-Arg399Gln, exon 10; X-ray repair cross-complementing group 3Thr241Met, exon 7; and xeroderma pigmentosum-DLys751Gln, exon 23) and their combinati...
