The transcription factor Forkhead box M1 (FOXM1) is a key regulator of cell proliferation and is overexpressed in many forms of primary cancers, leading to uncontrolled cell division and genomic instability. To address the role of FOXM1 in chemoresistance, we generated a cisplatin-resistant breast cancer cell line (MCF-7-CIS(R)), which had an elevated level of FOXM1 protein and mRNA expression ...

The present meta-analysis was intended to explore the relationship between the X-ray repair cross complementing 1 (XRCC1) polymorphisms (Arg194Trp, Arg280His and Arg399Gln) and cervical cancer risk. Several electronic databases were searched systematically and bibliographies of relevant papers were identified carefully. Then, a meta-analysis was performed based on eligible studies in various ge...

BACKGROUND Fuchs endothelial corneal dystrophy (FECD) is a corneal disease characterized by abnormalities in the Descemet membrane and the corneal endothelium. The etiology of this disease is poorly understood. An increased level of oxidative DNA damage reported in FECD corneas suggests a role of DNA base excision repair (BER) genes in its pathogenesis. In this work, we searched for the associa...

Polymorphisms in X-ray repair cross-complementing (XRCC) genes have been implicated in altering the risk of various urological cancers. However, the results of reported studies are controversial. To ascertain whether polymorphisms in XRCC genes are associated with the risk of urological neoplasms, we conducted present updated meta-analysis and systematic review. Summary odds ratios (ORs) and co...

DNA repair gene polymorphisms have been implicated as susceptibility factors in cancer development. It is possible that DNA repair polymorphisms may also influence the risk of gene mutation. The 399Gln polymorphism in the DNA repair gene XRCC1 has been indicated to have a contributive role in DNA adduct formation, sister chromatid exchange, and an increased risk of cancer development. Two hundr...

AIM To evaluate the association between polymorphisms XRCC1 Arg194Trp and Arg399Gln and XRCC3 Thr241Met and the risk for chronic gastritis and gastric cancer, in a Southeastern Brazilian population. METHODS Genotyping by PCR-RFLP was carried out on 202 patients with chronic gastritis (CG) and 160 patients with gastric cancer (GC), matched to 202 (C1) and 150 (C2) controls, respectively. RES...

The human gene that corrects the DNA repair defect of the CHO cell mutant EM9 is designated XRCC1 and is the first human gene to be cloned that has an established role in DNA strand-break repair. In this study, either an XRCC1 cosmid genomic fragment or synthetic oligonucleotides were ligated to an incomplete XRCC1 cDNA to generate two full-length XRCC1 cDNA constructs. The ability of these min...

Genetic polymorphisms in DNA repair genes may influence individual variations in the DNA repair capacity. Polymorphisms in the XRCC1 gene that cause amino acid substitutions may impair the interaction of its proteins (XRCC1) with the other enzymatic proteins and consequently alter DNA repair function, which may be associated with the risk of HIV-1/AIDS disease. In this study, we aimed to determ...

PURPOSE Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. METHODS PubMed, Google scholar and China Nati...

OBJECTIVE We aimed to analyze the association between excision repair cross-complementing rodent repair deficiency complementation group 1 (XRCC1) and ovarian cancer risk. METHODS We performed a hospital-based case-control study with 155 cases and 313 controls in China. All Chinese cases with newly diagnosed primary ovarian cancer between May 2005 to May 2010 in our hospital were invited to p...
