Multidrug resistance due to P-glycoprotein.
P-glycoprotein is a cell membrane transport protein in various human tissues that acts as an efflux pump, apparently to protect normal cells from environmental toxins. It is also a mechanism used by some cancer cells to resist chemotherapy. The gene responsible for P-glycoprotein is partially defined. Agents that inhibit the protein in tumors may make chemotherapy more effective and less toxic.
