NFAT2 inhibitor ameliorates diabetic nephropathy and podocyte injury in db/db mice.

ABSTRACT:

Background and purpose

Podocyte injury plays a key role in the development of diabetic nephropathy (DN). We have recently shown that 11R-VIVIT, an inhibitor of cell-permeable nuclear factor of activated T-cells (NFAT), attenuates podocyte apoptosis induced by high glucose in vitro. However, it is not known whether 11R-VIVIT has a protective effect on DN, especially podocyte injury, under in vivo diabetic conditions. Hence, we examined the renoprotective effects of 11R-VIVIT in diabetic db/db mice and the possible mechanisms underlying its protective effects on podocyte injury in vivo and in vitro.

Experimental approach

Type 2 diabetic db/db mice received i.p. injections of 11R-VIVIT (1 mg·kg(-1)) three times a week and were killed after 8 weeks. Immortalized mouse podocytes
