OBJECTIVES To comprehensively evaluate the association of ERCC1 C8092A and ERCC2 Lys751Gln polymorphisms with the risk of glioma. METHODS Potential studies were searched and selected through the Pubmed/MEDLINE, EMBASE, the China National Knowledge Infrastructure (CNKI) platforms, WanFang and VIP database up to June 2013. Two investigators independently reviewed full text and included studies ...

BACKGROUND Polymorphisms of DNA repair genes may affect the repair capacity of DNA damages and cause different responses towards chemotherapy. Excision repair cross-complementing group 2 (ERCC2) plays an important role in the nucleotide excision repair. OBJECTIVES The aim of this study was to investigate the association between ERCC2 single nucleotide polymorphisms (SNPs) and the response to ...

Introduction: DNA repair enzymes continuously monitor to correct damaged nucleotide residues generated by exposure environmental mutagenic and cytotoxic compounds or carcinogens. Our objective was investigate the association among XRCC1 (Arg399Gln Arg194Trp), XRCC3 (Thr241Met), XPD-ERCC2 (Lys751Gln), APE1 (Asp241Glu), PARP-ADPRT (Val762Ala) gene polymorphisms lung cancer in Turkish population. ...

We systematically analyzed the association of nine SNPs of seven key NER pathway genes with the development of laryngeal cancer patients, and investigated whether NER pathway polymorphisms could serve as potential biomarkers for laryngeal cancer risk. 271 patients with pathologically proven laryngeal cancer and 271 control subjects were included in our study. Genotyping of ERCC1 rs11615 and rs2...

Perturbation of the DNA repair process appears to be responsible for the occurrence of a number of human diseases, which are usually associated with a propensity to develop internal malignancies and/or disorders of the central nervous system. We have been interested in the possibility that a subtle abnormality in DNA repair competency might be associated with the transformation of nonmalignant ...

In this article, the author updates information on cerebro-oculo-facio-skeletal (COFS) syndrome. The condition is rare, with autosomal recessive inheritance, and manifests abnormal facies, ocular changes (eg, cataracts, retinal degeneration, microcornea, optic atrophy), in utero and postnatal growth retardation, severe psychomotor retardation, cerebral and cerebellar degeneration with calcifica...

The Mammary Prevention 3 (MAP.3) placebo-controlled randomized trial in 4,560 high-risk postmenopausal women showed a 65% reduction in invasive breast cancer with the use of exemestane at 35 months of median follow-up. Few differences in adverse events were observed between the arms, suggesting a promising risk:benefi t balance with exemestane for use in chemoprevention. Yet, the MAP.3 design a...

The xeroderma pigmentosum group D (XPD) protein is a well-characterized DNA helicase necessary for the nucleotide excision repair of bulky DNA lesions, such as those induced by cigarette smoking. Polymorphisms in several exons of the XPD gene have been identified; two of them, Asp312Asn and Lys751Gln, are common and result in an amino acid change. Most of the reported data indicate higher level...
