Abcc4 Together with Abcb1 and Abcg2 Form a Robust Cooperative Drug Efflux System That Restricts the Brain Entry of Camptothecin Analogues
6 Mar 2013
Abstract excerpt
PURPOSE: Multidrug resistance-associated protein 4 (ABCC4) shares many features with P-glycoprotein (ABCB1) and breast cancer resistance protein (ABCG2), including broad substrate affinity and expression at the blood-brain barrier (BBB). However, the pharmacologic relevance of ABCC4 at the BBB is difficult to evaluate, as most drugs are also substrates of ABCB1 and/or ABCG2. EXPERIMENTAL DESIGN: We have created a...
