MDR1 G1199A polymorphism alters permeability of HIV protease inhibitors across P-glycoprotein-expressing epithelial cells
23 Sept 2005
Abstract excerpt
OBJECTIVE: To evaluate the impact of the human multidrug resistance gene (MDR1) G1199A polymorphism (amino acid change Ser400Asn) on P-glycoprotein (P-gp)-dependent transepithelial permeability and uptake kinetics of HIV protease inhibitors (PI), by using recombinant epithelial cells expressing wild-type MDR1 (MDR1wt) or the G1199A variant (MDR1(1199A)). METHODS: Using a recombinant expression system developed...
