A novel VCP modulator KUS121 exerts renoprotective effects in ischemia-reperfusion injury with retaining ATP and restoring ERAD-processing capacity

Abstract

Novel findings of this study are as follows: 1) Kyoto University substance 121 (KUS121), a novel valosin-containing protein (VCP) modulator, can reduce ATP consumption of VCP; 2) KUS121 reduced endoplasmic reticulum (ER) stress and improved cell viability in proximal tubular cells; 3) KUS121 exerted renoprotective effects against ischemia-reperfusion injury; and 4) KUS121 may prevent ischemic acute kidney injury with ATP retention and restoring ER-associated degradation capacity.
