The role of the breast cancer resistance protein (ABCG2) in the distribution of sorafenib to the brain.

ATP-binding cassette transporters P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) have been shown to work in concert to restrict brain penetration of several tyrosine kinase inhibitors. It has been reported that P-gp is dominant in limiting transport of many dual P-gp/BCRP substrates across the blood-brain barrier (BBB). This study investigated the influence of P-gp […]
