abstract：:Multidrug resistance (MDR) is often characterized by the expression of P-glycoprotein (P-gp), a 170-kd ATP-dependent drug efflux protein. As well as effluxing xenotoxins, functional P-gp can confer resistance to caspase-dependent apoptosis induced by a range of different stimuli, including Fas ligand, tumor necrosis f...
