Research Abstract

We demonstrated that addition of recombinant prostasin to human adrenocortical cells increased secretion of aldosterone to the media in a dose dependent manner. We also showed that camostat mesilate, a potent serine-protease inhibitor, suppressed the progression of renal injury in aldosterone-induced renal injury model rats and in 5/6 nephrectomized renal failure model rats. Since camostat has been already clinically used as a medicine for pancreatitis and esophagitis in Japan, early clinical application of camostat for renal failure can be expected.
