| Research Abstract |
Recent studies have revealed that pregnane X receptor (PXR) can function as a master regulator to control the expression of drug-metabolizing enzymes, CYP3A family, as well as members of the drug transporter family, including MDR1. We observed that PXR-MDR pathway was expressed in various ovarian cancer tissues and that PXR down-regulation caused a significant increase in cell growth inhibition and enhancement of apoptosis in the presence of the anti-cancer agents, paclitaxel, cisplatin. PXR down-regulation could be a novel therapeutic approach for the augmentation of sensitivity to anticancer agents, or to overcome resistance to them, in the treatment of ovarian cancer.
