| Research Abstract |
Transporters are the membrane proteins involved in permeation of drug molecules across plasma membranes. Although they are assumed to play fundamental roles in drug absorption and disposition, little information is available on their direct association with drug efficacy and toxicity. Therefore, the aim of the present study was to clarify pharmacokinetic, pharmacodynamic and toxicodynamic roles of transporters by focusing on their adaptor proteins which have already been clarified by our previous studies. As the final results of this grant, we have clarified (i) the roles of carnitine/organic cation transporters (OCTNs) in drug disposition and efficacy in small intestine, liver, kidney and heart, (ii) the roles of influx and efflux transporters in gastrointestinal drug absorption, and (iii) direct interaction and regulation of three intestinal influx transporters by an adaptor protein PDZK1.
