We investigated the association between the clinical outcome and GSTP1 and XRCC1 gene polymorphisms in advanced NSCLC patients with cisplatin-based chemotherapy. We prospectively recruited 325 NSCLC patients between January 2010 and January 2014. Genotypes of GSTP1 A313G, XRCC1 Arg194Trp, Arg280His and Arg399Gln were conducted using polymerase chain reaction restriction fragment length polymorp...
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...
Background and purpose: Oral squamous cell carcinoma (OSCC) is the most common tumor of the head and neck. XRCC1 is a DNA repair gene and there are controversies about the association between XRCC1 gene polymorphism (RS1799782) in pathogenesis and susceptibility to OSCC. The purpose of this study was to investigate the association between XRCC1 (rs1799782) gene polymorphism and its dominant all...
BACKGROUND While single nucleotide polymorphisms (SNP) in genes involved in DNA repair or drug metabolism have been shown to influence survival of metastatic colon cancer patients treated with FOLFOX, data on adjuvant setting are scarce. METHODS This study evaluated the correlation between disease-free survival (DFS) of 210 unselected stage III colon cancer patients receiving FOLFOX chemother...
We conducted this study to detect associations between XRCC1 Arg399Gln and XPD Lys751Gln genotypes and survival of colorectal cancer patients treated with 5-FU/oxalipatin chemotherapy. We included 289 Chinese patients with advanced colorectal cancer, who had received 5-FU/oxalipatin chemotherapy as first-line treatment from January 2005 to January 2007. All patients were followed up till Nov. 2...
OBJECTIVE We conducted a case-control study to examine the role of XRCC1 codons 194 (Arg>Trp), 280 (Arg>His) and 399 (Arg>Gln) polymorphisms in the risk of prostate cancer. METHODS This study included 572 consecutive primary prostate cancer patients and 572 controls between January 2011 and January 2014. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was per...
BACKGROUND This study aimed to examine the relationship between XRCC1, p53 and MDR1 protein, along with polymorphisms of their genes and their prognostic values in breast cancer. The following clinical and pathological parameters were evaluated: histopathological type of tumor, grade, stage, Her2/neu expression, ER, PR positivity and involvement of regional lymph nodes. MATERIAL/METHODS Expre...
OBJECTIVE The relationship between APE1 and XRCC1 gene polymorphism and the susceptibility to hepatocellular carcinoma (HCC) was discussed, and the effect of APE1 and XRCC1 gene polymorphism on the sensitivity of HCC to cisplatin was investigated. METHOD From January 2010 to August 2014, 118 HCC patients were admitted to our hospital. 120 patients treated for non-tumor diseases during this pe...
Polymorphisms in several DNA repair genes have recently been identified, but little is known about their phenotypic significance. To determine whether variation in DNA repair genes is related to host DNA damage, we studied the association between polymorphisms in XRCC1 (codon 399) and ERCC2 (codon 751) and two markers of DNA damage, sister chromatid exchange (SCE) frequencies (n = 76) and polyp...
چکیده زمینه و هدف: سرطان معده یکی از شایع ترین بدخیمی ها می باشد و تشخیص زود هنگام می تواند در روش درمان مؤثر باشد. ناپایداری ژنومی و در نتیجه بروز تغییرات ژنی یک مرحله مولکولی و پاتوژنیک قاطع می باشد که در اوایل روند سرطان زایی معده رخ می دهد. ژن xrcc1 یکی از مهم ترین ژن های ترمیم dna می باشد. پروتئین xrcc1 نقش اساسی در مسیر ترمیم dna با برداشت باز ایفا می کند. پلی مورفیسم های ژن xrcc1 توانایی...
