BACKGROUND Pathological stage III/N2 non-small cell lung cancer (NSCLC) is heterogeneous, and the optimal prognostic marker for survival remains unclear in Chinese patients. The aim of the present study was to assess the prognostic value of the clinicopathologic features and excision repair cross-complementing group-1 (ERCC1) in resected p-stage III/N2 NSCLC patients that received cisplatin-bas...
BACKGROUND We aimed to investigate the impact of RRM1 and ERCC1 expression on response to cisplatin and/or gemcitabine chemotherapy in patients with lung, ovarian or pancreatic cancer. MATERIAL AND METHODS Patients with lung, ovarian or pancreatic cancer, who used cisplatin and/or gemcitabine therapy were included; hospital files were examined and RRM1 and ERCC1 expression were evaluated with...
Praz and colleagues report in this issue on the relationship between the occurrence of a polymorphism of ERCC1 in tumor tissues of patients with colorectal cancer and the rate of disease response to the combination of oxaliplatin and 5-fluorouracil (1). This polymorphism is associated with reduced translation of the gene, and presumably, reduced DNA repair capability. Their report suggests that...
OBJECTIVE To investigate the relationship between excision repair cross-complementing group 1 (ERCC1)-4533/8092, tumor necrosis factor-alpha (TNF-α)-238/308 polymorphisms, and the risk of hepatocellular carcinoma (HCC) in Guangxi Zhuang population of China. METHODS Polymerase chain reaction-restriction fragment length polymorphism method was used to detect the ERCC1-4533/8092 and TNF-α-238/30...
ERCC1 is a protein which is found to be associated with resistance to platinum-based chemotherapy. FDG uptake is considered as a prognostic marker in patients with NSCLC and provides information beyond that of TNM staging. The aim of this study is to examine both prognostic values of ERCC1 expression and 18F-FDG uptake on PET and their relationship in patients who underwent pulmonary resection ...
Platinum compounds are the foundation of chemotherapy regimens for non-small cell lung cancer (NSCLC) despite poor response rates and limited response duration. It has been reported that tumor expression of excision repair cross-complementation group 1 (ERCC1), a key component in nucleotide excision repair, may correlate with clinical response to platinum agents. We found that most primary lung...
Human ERCC1/XPF is a structure-specific endonuclease involved in multiple DNA repair pathways. We present the solution structure of the non-catalytic ERCC1 central domain. Although this domain shows structural homology with the catalytically active XPF nuclease domain, functional investigation reveals a completely distinct function for the ERCC1 central domain by performing interactions with bo...
INTRODUCTION There are numerous studies addressing associations of polymorphisms in DNA repair genes and cancer risks because accurate and efficient DNA repair is crucial to genomic integrity and fidelity. ERCC1 is important in DNA nucleotide excision repair. MATERIAL AND METHODS We genotyped constitutive variants of ERCC1 in approximately 300 adults with breast adenocarcinoma and 126 control...
During replication-coupled DNA interstrand crosslink (ICL) repair, the XPF-ERCC1 endonuclease is required for the incisions that release, or "unhook", ICLs, but the mechanism of ICL unhooking remains largely unknown. Incisions are triggered when the nascent leading strand of a replication fork strikes the ICL Here, we report that while purified XPF-ERCC1 incises simple ICL-containing model repl...
Nucleotide excision repair proteins have been implicated in genetic recombination by experiments in Saccharomyces cerevisiae and Drosophila melanogaster, but their role, if any, in mammalian cells is undefined. To investigate the role of the nucleotide excision repair gene ERCC1, the hamster homologue to the S. cerevisiae RADIO gene, we disabled the gene by targeted knockout. Partial tandem dup...
