DNA-protein cross-links are induced in mammalian cells by X-rays, ultraviolet light, fluorescent light, and numerous chemical carcinogens. Others have shown that these cross-links are repaired by normal cells but that excision repair-deficient xeroderma pigmentosum (XP) Group A cells, XP12BE, are deficient in repair of these bulky adducts. This paper compares the DNA-protein cross-link repair c...
زمینه: x-ray repair cross complementing group 1 (xrcc1) به عنوان یک پروتئین داربستی در ترمیم برداشت باز آلی (ber) و ترمیم شکست تک رشته dna (ssbr) عمل می کند. پلی مورفیسم های این ژن موجب تغییر در بازده ترمیم می شوند که ممکن است زمینه ابتلای افراد به بیماری های مختلف را فراهم سازد. هدف از این پژوهش بررسی ارتباط بین پلی مورفیسم xrcc1 arg194trp و ناباروری ایدوپاتیک مردان در استان گیلان میباشد. موا...
background & aim: repair or replacement of restorations is one of the main necessities for health promotion. however, it has its own physical, psychological and economical side effects. the aim of this study was to investigate the prevalence of factors causing restoration replacement or repair. methods & materials: a non probable sampling was used for this cross – sectional observational descri...
X-ray Repair Cross Complementing 1 (XRCC1) is thought to function as a scaffolding protein in both base excision repair and single-strand break repair (SSBR), since it interacts with several proteins participating in these related pathways and has no known enzymatic activity. Moreover, studies indicate that XRCC1 possesses discrete G1 and S phase-specific functions. To further define the contri...
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...
During mammalian base excision repair (BER) of lesion-containing DNA, it is proposed that toxic strand-break intermediates generated throughout the pathway are sequestered and passed from one step to the next until repair is complete. This stepwise process is termed substrate channeling. A working model evaluated here is that a complex of BER factors may facilitate the BER process. FLAG-tagged ...
Background: The x-ray repair cross-complementing group 3 (XRCC3) encodes a protein involved in the homologous recombination repair (HRR) pathway for double-strand DNA repair. Associations of the XRCC3 Thr241Met polymorphism with various cancers have been widely reported. However, published data on links between XRCC3 Thr241Met and gastrointestinal (GI) cancer risk are inconsistent. Objective an...
