Recent progress in P-glycoprotein research

P-glycoprotein can extrude a variety of structurally diverse, toxic xenobiotic compounds from cells. It is believed to be one of key molecules which can cause multidrug resistance in cancer. This paper deals with recent progress in P-glycoprotein research, especially in its structure, mechanisms for substrate recognition and transport. The review also discusses specific modulators of multidrug resistance in cancer and gene therapy using the MDR1 gene.
