HNF-4α promotes multidrug resistance of gastric cancer cells through the modulation of cell apoptosis

Multidrug resistance (MDR) typically leads to treatment failure, and is associated with disease progression of gastric cancer (GC). In the present study, a total of 15 aberrantly activated transcription factors (TFs) were detected in chemo-resistant GC cells using a TF Activation Profiling Plate Array. Among these TFs, hepatocyte nuclear factor (HNF)-4α was significantly upregulated in multidru...

Germacrone reverses Adriamycin resistance through cell apoptosis in multidrug-resistant breast cancer cells

Multidrug resistance (MDR) is a major obstacle to the chemotherapeutic treatment of breast cancer. Germacrone, the main component of Rhizoma Curcuma, has been shown to possess antitumor, anti-inflammatory and immunomodulatory properties. The aim of the present study was to investigate the effect of germacrone on MCF-7/Adriamycin (ADR) multidrug-resistant human breast cancer cells. The treatment...

Modulation of multidrug resistance and apoptosis of cancer cells by selected carotenoids.

The multidrug resistance (MDR) proteins that belong to the ATP-binding casette superfamily are present in a majority of human tumors and are an important final cause of therapeutic failure. Therefore, compounds which inhibit the function of the MDR-efflux proteins may improve the cytotoxic action of anticancer chemotherapy. The effects of carotenoids were studied on the activity of the MDR-1 ge...

MiR-30a Decreases Multidrug Resistance (MDR) of Gastric Cancer Cells

BACKGROUND The effectiveness of chemotherapy for gastric cancer is largely limited by either intrinsic or acquired drug resistance. In this study, we aimed to explore the association between miR-30a dysregulation and multidrug resistance (MDR) in gastric cancer cells. MATERIAL AND METHODS We recruited 20 patients with advanced gastric cancer. Chemosensitivity was assessed after completion of th...

Silibinin promotes the apoptosis of gastric cancer BGC823 cells through caspase pathway.

PURPOSE To investigate the effects of silibinin, a natural compound, on the proliferation and apoptosis of BGC-823 gastric cancer cell line and to figure out the relevant pathways. METHODS BGC-823 gastric cancer cells were treated with silibinin at various concentrations (0,25,50,100,150 and 200μM). Zero μM was the control group and the other concentrations were defined as the experimental gr...
