Advanced-stage ovarian cancer is characterized by high mortality due to development of resistance to conventional chemotherapy. Novel compounds that can enhance the efficacy of conventional chemotherapy in ovarian cancer may overcome this drug resistance. Consumption of green tea (epigallocatechin gallate, EGCG) and cruciferous vegetables (sulforaphane, SFN) is inversely associated with occurre...

Ovarian cancer is the most lethal gynecological cancer in which cisplatin-based treatment plays a fundamental role as the first line chemotherapy option. However, development of platinum-resistance is a critical and poorly understood problem in ovarian cancer treatment. Although in vitro generation of platinum-resistant ovarian cancer cell lines is a long established approach to uncover the mol...

Cisplatin is a classical chemotherapeutic agent used in treating several forms of cancer including head and neck. However, cells develop resistance to the drug in some patients through a range of mechanisms, some of which are poorly understood. Using isolated plasma membrane vesicles as a model system, we present evidence suggesting that cisplatin induced resistance may be due to certain change...

Resistance to platinum-based therapies arises by multiple mechanisms, including by alterations to cell-cycle kinases that mediate G(2)-M phase arrest. In this study, we conducted parallel high-throughput screens for microRNAs (miRNA) that could restore sensitivity to cisplatin-resistant cells, and we screened for kinases targeted by miRNAs that mediated cisplatin resistance. Overexpression of t...

In this study, we investigated the mechanism by which lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) mediates cisplatin resistance in lung cancer. Lung cancer patients with high MALAT1 levels were associated with cisplatin resistance and low overall survival. Moreover, cisplatin-resistant A549/DDP cells showed higher MALAT1 expression than cisplatin-sensitive lung cancer...

Cisplatin is a well-known chemotherapeutic agent, it could cause DNA damage and induce apoptotic cell death, but the cisplatin resistance also appears, it's important to reveal the mechanisms of cisplatin resistance [1]. URGCP/URG4 is overexpressed in various tumors and plays critical role during tumor development. We found URGCP/URG4 was upregulated in bladder cancer cells and tissues, URGCP/U...

Hereditary cancers derive from gene defects that often compromise DNA repair. Thus, BRCA-associated cancers are sensitive to DNA-damaging agents such as cisplatin. The efficacy of cisplatin is limited, however, by the development of resistance. One cisplatin resistance mechanism is restoration of homologous recombination (HR), which can result from BRCA reversion mutations. However, in BRCA2 mu...

Our previous studies revealed that daintain/AIF-1 promoted the proliferation and migration of breast cancer cells. In the present study, we investigated the effect of daintain/AIF-1 on the cisplatin resistance of breast cancer cells. The results indicated that daintain/AIF-1 reinforced the resistance of breast cancer cells to cisplatin by inhibition of cell apoptosis and reduction of intracellu...

Fourier Transformed Infrared Spectroscopy (FTIR) has extensively been used for biological applications. Cisplatin is one the most useful antineoplastic chemotherapy drugs for a variety of different human cancers. One of the clinical problems in its application, which would consequently affect the therapeutic outcome of its application, is the occurrence of resistance to this agent. In this proj...

C isplatin [cis-diamminedichloroplatinum (II)] is a highly active anticancer agent. This agent is curative against most testicular cancers and is highly active against a wide range of other tumor types, notably ovarian, bladder carcinoma, and non-small-cell lung cancer (1). Treatment failure is frequently caused by the development of resistance to cisplatin. Although the insensitive tumors gene...
