Abstract
Gene amplification is responsible both for dihydrofolate reductase induced methotrexate resistance, and for the P-glycoprotein encoding multigene family induced multidrug resistance. The 6 pairs of hydrophobic regions of the P-glycoprotein fold up in a snake-like structure through the lipidic layers of the cell membrane. Other detoxification mechanisms include the glutathione S-transferase 'pi', but without gene amplification.Entities:
