摘要
Background P-glycoprotein （P-gp） encoded by ATP-binding cassette sub-family B member 1 （ABCB1） gene is a kind of ATP-dependent drug transporter, which plays important roles in multidrug resistance （MDR） of human cancers, such as osteosarcoma. Curcumin is a natural phenolic coloring compound originating from the rhizomes of Curcuma Ionga, which is proved to possess antitumor biological activities including reversion of MDR. However, the effect and molecular mechanisms of curcumin to osteosarcoma MDR remain unclear.
