Abstract
This study aimed to investigate the effects of various types of exercise on organic anion transporter 3 (Oat3) function, a major transporter that plays a role in the secretion of a variety of drugs and endogenous compounds. Male Wistar rats were randomly allocated to non-exercise, exhaustive, acute and training exercise groups. The function of Oat3 was assessed by the uptake of [3H]-estrone sulfate ([3H]-ES) into rat renal cortical slices. Acute and training exercises had no effect on [3H]-ES uptake whereas a marked reduction in [3H]-ES uptake occurred immediately after exhaustive exercise. However, the reduction in Oat3 function was gradually recovered at 6 and 24 h after the exercise session. Importantly, the impairment of Oat3 function was associated with a decrease in renal Oat3 protein expression. Our results indicate that exhaustive exercise produces a significant impact on renal organic anion transport function, which in turn could alter the plasma level of drugs and compounds in the body.
