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...
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...
Altered DNA repair capacity can result in increased susceptibility to cancer. The base excision repair (BER) pathway effectively removes DNA damage caused by ionizing radiation and reactive oxidative species (ROS). In the current study, we analyzed the possible relation of polymorphisms in BER genes, including 8-oxoguanine DNA glycosylase (OGG1), apurinic/apyrimidinic endonuclease 1 (APE1), and...
The consequences of PARP-1 disruption or inhibition on DNA single-strand break repair (SSBR) and radio-induced lethality were determined in synchronized, isogenic HeLa cells stably silenced or not for poly(ADP-ribose) polymerase-1 (PARP-1) (PARP-1(KD)) or XRCC1 (XRCC1(KD)). PARP-1 inhibition prevented XRCC1-YFP recruitment at sites of 405 nm laser micro irradiation, slowed SSBR 10-fold and trig...
The base excision repair (BER) pathway is important in repairing DNA damage incurred from occupational exposure to 1,3-butadiene (BD). This study examines the relationship between inherited polymorphisms of the BER pathway (x-ray repair cross-complementing group 1 (XRCC1) Arg194Trp, Arg280His, Arg399Gln, T-77C, ADPRT Val762Ala, MGMT Leu84Phe and APE1 Asp148Glu) and chromosomal damage in BD-expo...
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...
