Drug transporters: Gatekeepers controlling access of xenobiotics to the cellular interior

Abstract excerpt

In this paper, we evaluate methodologies and null mouse models used to study drug transporter function in vitro and in vivo. P-glycoprotein and MRP null mice have been used to examine many aspects of xenobiotic distribution and bioavailability. Their advantage over conventional models is that they allow the exclusion of transporters from a particular process; however, they cannot be used to study the activity of...
