Decitabine (5-aza-2'-deoxycytidine, 5-azadC) is used in the treatment of Myelodysplatic syndrome (MDS) and Acute Myeloid Leukemia (AML). Its mechanism of action is thought to involve reactivation of genes implicated in differentiation and transformation, as well as induction of DNA damage by trapping DNA methyltranferases (DNMT) to DNA. We demonstrate for the first time that base excision repai...
Single-strand break repair (SSBR) and base excision repair (BER) of modified bases and abasic sites share several players. Among them is XRCC1, an essential scaffold protein with no enzymatic activity, required for the coordination of both pathways. XRCC1 is recruited to SSBR by PARP-1, responsible for the initial recognition of the break. The recruitment of XRCC1 to BER is still poorly underst...
زمینه و هدف : آمیکاسین یکی از داروهای کلیدی خط 2 برای درمان سل میباشد. جهش در کدونهای 1400، 1401 و 1483 از ژن srRNA 16 با مقاومت به آمیکاسین در ارتباط است. هدف از این مطالعه آشکارسازی این جهشها با استفاده از روش PCR-RFLP درسوشهای مقاوم به چند دارو ( MDR Multiple Drug Resistant ) مایکوباکتریوم توبرکلوزیس مقاوم به آمیکاسین بود. روشکار : آزمون ارزیابی حساسیت دارویی با استفاده از روش تناسب...
XRCC1-399 allele polymorphisms have been reported to be associated with susceptibility to hepatocellular carcinoma (HCC), but the conclusions of the various studies have been inconsistent. We conducted a meta-analysis of available studies to determine whether XRCC1-399 alleles influence susceptibility to hepatocellular carcinoma. We searched English-language databases, including PubMed, Medline...
Although various individual studies have evaluated the correlation between X-ray repair cross-complementing group 1 (XRCC1) polymorphisms and cervical cancer, the current results remain inconclusive. Therefore, we performed a pooled analysis based on Chinese individuals to provide comprehensive data on the association between XRCC1 Arg399Gln, Arg194Trp, Arg280His polymorphisms and cervical canc...
در این تحقیق وضعیت چندشکلی تک نوکلئوتیدی ژنهای prkag3 و n-rap به روش pcr-rflp در اسبهای نژاد تروبرد موجود در استان مرکزی و اسبهای نژاد ترکمن موجود در استان گلستان مورد بررسی قرار گرفت. به این منظور از 40 رأس اسب نژاد تروبرد و ترکمن وارداتی در استان مرکزی واستان گلستان خونگیری به عمل آمد. سپس به روش rflp وضعیت چندشکلی هر ژن توسط آنزیمهای محدودکننده alui و bsegi روی ژل آگاروز 3 درصد و 5/2 درصد مو...
INTRODUCTION Our retrospective cohort study investigated the effect of tumor site and stage on the associations between the allelic variants of glutathione S-transferase (GST) and DNA-repair genes and overall survival (OS) in CRC patients treated with 5-fluorouracil (5-FU)-based adjuvant chemotherapy. MATERIAL AND METHODS We genotyped GSTM1, GSTT1, GSTP1 Ile105Val, XRCC1 Arg399Gln, XRCC3 Thr2...
Purpose:We evaluated X-ray repair complementing defective repair in Chinese hamster cells 1 (XRCC1) protein in head and neck squamous cell carcinoma (HNSCC) patients in association with outcome. Experimental Design: XRCC1 protein expression was assessed by immunohistochemical (IHC) staining of pretreatment tissue samples in 138 consecutive HNSCC patients treated with surgery (n 1⁄4 31), radiati...
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...
OBJECTIVE A novel T-77C polymorphism in the promoter region of the DNA repair gene X-ray cross-complementing group 1 (XRCC1) may modulate its transcription to increase the risk of lung cancer. Here, we attempt to clarify: (i) whether the XRCC1 T-77C polymorphism was associated with lung cancer risk in Taiwanese and (ii) whether this polymorphism could act as a prognostic indicator to predict th...
