Downregulation of transient receptor potential M6 channels as a cause of hypermagnesiuric hypomagnesemia in obese type 2 diabetic rats

Kaori Takayanagi, Taisuke Shimizu, Yosuke Tayama, Akira Ikari et autres

We assessed the expression profile of Mg(2+)-transporting molecules in obese diabetic rats as a cause of hypermagnesiuric hypomagnesemia, which is involved in the development of insulin resistance, hypertension, and coronary diseases. Kidneys were obtained from male Otsuka Long-Evans Tokushima fatty (OLETF) and …

Prevention of lipopolysaccharide-induced peritoneal damage by eplerenone in rats undergoing peritoneal dialysis

Yosuke Tayama, Hajime Hasegawa, Kaori Takayanagi, Akihiko Matsuda et autres

BACKGROUND: Bacterial peritonitis in patients undergoing peritoneal dialysis (PD) is a major cause of therapy interruption due to peritoneal insufficiency. Here we studied the effect of a selective mineralocorticoid receptor (MR) blocker, eplerenone, on the prevention of peritoneal damage. METHODS: Male Sprague-Dawley …
