How does MDR gene act?
Correct Answer: Cause efflux of drug
Description: The multidrug resistance (MDR) gene encodes a protein that actively pumps drugs out of tumor cells. This gene confers resistance on a variety of antitumor drugs, including the antibiotics and plant-derived compounds. Tumor resistance to a given chemotherapeutic agent can often be overcome by the administration of multiple drugs. Ref: Sabel M.S. (2010). Chapter 44. Oncology. In G.M.
