Oxaliplatin is known to be a platinum-based chemotherapeutic agent that carries a 1, 2-diamino-cyclohexane ring. This drug has shown in vitro and in vivo antitumor activities in patients with colorectal cancer (CRC) [1]. The addition of oxaliplatin to 5FU (FOLFOX regimen) was shown to improve the adjuvant treatment of stage-III colon cancer by reducing the risk of recurrence and increasing over...
Molecular biomarkers to determine the effectiveness of targeted therapies in cancer treatment have been widely adopted in colorectal cancer (CRC), but those to predict chemotherapy sensitivity remain poorly defined. We tested our hypothesis that KRAS mutation may be a predictor of oxaliplatin sensitivity in CRC. KRAS was knocked-down in KRAS-mutant CRC cells (DLD-1(G13D) and SW480(G12V)) by sma...
BACKGROUND In order to improve the outcome of patients with non-small cell lung cancer (NSCLC), a biomarker that can predict the efficacy of chemotherapy is needed. The aim of this study was to assess the role of EGFR mutations and ERCC1 in predicting the efficacy of platinum-based chemotherapy and the outcome of patients with NSCLC. METHODS We conducted a retrospective study to analyze the r...
The interstrand crosslink (ICL) presents a challenge to both the cell and the scientist. From a clinical standpoint, these lesions are particularly intriguing: ICL-inducing agents are powerful tools in cancer chemotherapy, and spontaneous ICLs have recently been linked with accelerated aging phenotypes. Nevertheless, the ICL repair process has proven difficult to elucidate. Here we discuss rece...
Approximately 15-20% of ovarian cancer patients receiving platinum-based chemotherapy are primary platinum-resistant. Identification of these patients and transfer to other more effective therapy could reduce the morbidity of ovarian cancer. ERCC1 is a DNA repair gene which can complex with XPF to repair cisplatin-induced DNA damage and cause chemotherapy resistance. In this study, we found a n...
We conducted a perspective study to investigate the role of ERCC1 (rs11615), ERCC2 (rs13181 and rs1799793), ERCC4 (rs1800067), and ERCC5 (rs17655) in NER pathway in the prognosis of osteosarcoma patients. In total, 146 osteosarcoma patients were recruited between 2008 and 2013. ERCC1 rs11615, ERCC2 rs13181 and rs1799793, ERCC4 rs1800067, and ERCC5 rs17655 gene polymorphisms were assessed by pol...
PURPOSE We evaluated the clinical utility of excision repair cross-complementation group 1 (ERCC1) expression as a predictive biomarker for platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Eligible patients were randomly assigned to the GP (gemcitabine 1,250 mg/m2 on days 1 and 8, and cisplatin 75 mg/m2 on day 1 every 3 weeks) or IP (irinotecan...
PURPOSE ERCC1 and ERCC2 play critical roles in the nucleotide excision repair pathway that effectively repairs DNA damage induced by chemotherapeutic agents. Therefore, functional single nucleotide polymorphisms (SNPs) in these genes could have an impact on clinical outcomes in cancer patients who received chemotherapy. However, few studies have simultaneously investigated the roles of ERCC1 an...
In patients with metastatic colon cancer, response to first line chemotherapy is a strong predictor of overall survival (OS). Currently, oncologists lack diagnostic tests to determine which chemotherapy regimen offers the greatest chance for response in an individual patient. Here we present the results of gene expression analysis for two genes, ERCC1 and TS, measured with the commercially avai...
In this study, we show that silencing of CITED2 using small-hairpin RNA (shCITED2) induced DNA damage and reduction of ERCC1 gene expression in HEK293, HeLa and H1299 cells, even in the absence of cisplatin. In contrast, ectopic expression of ERCC1 significantly reduced intrinsic and induced DNA damage levels, and rescued the effects of CITED2 silencing on cell viability. The effects of CITED2 ...
