PURPOSE The development of drug-resistant phenotypes has been a major obstacle to cisplatin use in non-small-cell lung cancer. We aimed to identify some of the molecular mechanisms that underlie cisplatin resistance using microarray expression analysis. METHODS AND MATERIALS H460 cells were treated with cisplatin. The differences between cisplatin-resistant lung cancer cells and parental H460...

Cisplatin is a commonly used chemotherapeutic drug, used for the treatment of malignant ovarian cancer, but acquired resistance limits its application. There is therefore an overwhelming need to understand the mechanism of cisplatin resistance in ovarian cancer, that is, ovarian cancer cells are insensitive to cisplatin treatment. Here, we show that failure of elevating calcium and oxidative st...

Paclitaxel plus cisplatin and 5-fluorouracil plus cisplatin treatments are effective strategies for patients with advanced esophageal squamous cell carcinoma. This study was to evaluate the safety and efficacy of paclitaxel plus cisplatin and 5-fluorouracil plus cisplatin as first-line chemotherapy for patients with advanced esophageal squamous cell carcinoma. A total of 398 patients with advan...

objective(s): although tumor necrosis factor-related apoptosis-inducing ligand (trail) can selectively induce apoptosis in tumor cells, more than half of tumors including non-small cell lung cancer (nsclc) exhibit trail-resistance. the purpose of this study was to determine whether subtoxic-dose cisplatin and trail could synergistically enhance apoptosis on nsclc cells and investigate its under...

Cisplatin is an effective chemotherapeutic drug used to treat many types of tumours. However, it may cause male reproductive toxicity. Gallic acid exhibits beneficial effects such as antioxidant, anti-inflammatory and antitumor. The current study investigated the gallic against testis epididymis toxicity induced by cisplatin. Male rats were divided into 4 groups follows (n = 7): Control, cispla...

Base excision repair (BER) and mismatch repair (MMR) pathways play an important role in modulating cis-Diamminedichloroplatinum (II) (cisplatin) cytotoxicity. In this article, we identified a novel mechanistic role of both BER and MMR pathways in mediating cellular responses to cisplatin treatment. Cells defective in BER or MMR display a cisplatin-resistant phenotype. Targeting both BER and MMR...

Cisplatin treatment activates multiple signal transduction pathways, which can lead to several cellular responses including cell cycle arrest, DNA repair, survival, or apoptosis. We investigated the response of the mitogen-activated protein kinases, extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun-N-terminal kinase 1 (JNK1), and p38, to cisplatin treatment in the ovarian carcinoma...

Flap endonuclease 1 (FEN1) overexpression promotes breast cancer. We investigated the role of FEN1 in cisplatin resistance and the chemosensitizing effects of curcumin in breast cancer cells. We demonstrated that FEN1 overexpression promotes cisplatin resistance in breast cancer cells, and that FEN1 knockdown enhances cisplatin sensitivity. Curcumin down-regulated FEN1 expression in a dose-depe...

OBJECTIVE The aim of this study was to compare the efficacy and toxicity of different concurrent chemoradiotherapy (CCRT) regimens in the treatment of advanced cervical cancer (CC) by adopting a network meta-analysis. METHODS We searched PubMed and Cochrane Library from the inception of these databases to September 2016, and all cohort studies (CSs) related to different CCRT regimens in the t...

Combination chemotherapy using paclitaxel with a platinum-based regimen is currently the standard first-line therapy for ovarian cancer after surgical cytoreduction. Whereas cisplatin-paclitaxel combination chemotherapy has shown significant efficacy over previous drug combinations in ovarian cancer, 20–30% of patients fail to respond to this combination. These patients are deemed cisplatin-pac...
