| Research Abstract |
Effect of oxidative stress on the expression and function of organiccation transporter swere studied using cultured renal epithelial cell 1ine, LLC-PK_1, which retains organic cation transporters, and rats subjected to liver ischemia-reperfusion. Influx of cationic drugs across basolateral membranes into renal epithelial cells were decreased by oxidative stress by direct or indirect effect, and the involvement of decreased expression of organic cation transporter, OCT2, was suggested. These results provideuseful information for analysisof renal clearance of cationicdrugs in occasions of organdysfunction accompanying oxidative stress.
