PURPOSE Despite discrepant results on clinical utility, several trials are already prospectively randomizing non-small cell lung cancer (NSCLC) patients by ERCC1 status. We aimed to characterize the prognostic and predictive effect of ERCC1 by systematic review and meta-analysis. METHODS Eligible studies assessed survival and/or chemotherapy response in NSCLC or SCLC by ERCC1 status. Effect m...

BACKGROUND An antibody with cross-reactivity can create unexpected side effects or false diagnostic reports if used for clinical purposes. ERCC1 is being explored as a predictive diagnostic biomarker for cisplatin-based chemotherapy. High ERCC1 expression is linked to drug resistance on cisplatin-based chemotherapy. 8F1 is one of the most commonly used monoclonal antibodies for evaluating ERCC1...

Etoposide (VP-16), a topoisomerase II inhibitor, is an effective anticancer drug currently used for the treatment of a wide range of cancers. Excision repair cross-complementary 1 (ERCC1) is a key protein involved in the process of nucleotide excision repair. High level of ERCC1 expression in cancers is associated with resistance to DNA damage-based chemotherapy. In this study, the effects of p...

XPF and ERCC1 exist as a heterodimer to be stable and active in cells and catalyze DNA cleavage on the 5'-side of a lesion during nucleotide excision repair. To characterize the specific interaction between XPF and ERCC1, we expressed the human ERCC1 binding domain of XPF (XPF-EB) and the XPF binding domain of ERCC1 (ERCC1-FB) in Escherichia coli. Milligram quantities of a heterodimer were char...

Purpose: Multimodality treatment of squamous cell carcinoma of the head and neck (SCCHN) often involves radiotherapy and cisplatin-based therapy. Elevated activity of DNA repair mechanisms, such as the nucleotide excision repair (NER) pathway, of which ERCC1 is a rate-limiting element, are associated with cisplatin and possibly RT resistance. We have determined excision repair cross-complementi...

This study aimed to assess the predictive value of combined Ki67 and ERCC1 in distant metastasis-free nasopharyngeal carcinoma. 334 such cases were retrospectively assessed. Immunohistochemistry was used to evaluate Ki67 and ERCC1 protein levels in tumor tissues. Associations of Ki67 and ERCC1 amounts with clinical characteristics and survival were analyzed. Medium follow-up was 48.7 months; ov...

PURPOSE The aim of this study was to determine whether the ERCC1 expression is effective to predict the clinical outcomes of patients with advanced gastric cancer (AGC) and who were treated with cisplatin-based first-line chemotherapy. MATERIALS AND METHODS A total of 89 measurable AGC patients received cisplatin and capecitabine, with or without epirubicin, as a part of a randomized phase II...

The ERCC1 protein is essential for nucleotide excision repair in mammalian cells and is also believed to be involved in mitotic recombination. ERCC1-deficient mice, with their extreme runting and polyploid hepatocyte nuclei, have a phenotype that is more reminiscent of a cell cycle arrest/premature ageing disorder than the classic DNA repair deficiency disease, xeroderma pigmentosum. To underst...

BACKGROUND AND AIM The effects of DNA repair pathway on survival were assessed by measuring the tumoral excision repair cross complementation 1 (ERCC1) expression in patients with resected non-small cell lung carcinoma (NSCLC). We aimed to determine the prognostic and predictive significance of ERCC1 in patients with completely resected NSCLC. METHODS Immunohistochemistry (IHC) was used to as...

Our study aimed to investigate the correlation between single nucleotide polymorphisms of ERCC1/XRCC1/XPA genes and postoperative chemotherapy efficacy and prognosis of endometrial carcinoma. Our study included 108 patients with endometrial carcinoma and 100 healthy participants. ERCC1 rs11615/XRCC1 rs25487/XPA rs1800975 gene polymorphisms were detected by polymerase chain reaction-restriction ...
