dc.description.abstract | The accumulation of extracellular matrix proteins in the interstitial area is the final common feature of chronic kidney diseases. Accumulating evidence suggests that transforming growth factor (TGF)-beta 1 promotes the development of renal fibrosis. Heat shock protein (Hsp) 90 inhibitors have been shown to repress TGF-beta 1 signaling, but whether they inhibit renal fibrosis is unknown. The purpose of this study is to determine the therapeutic efficacy of Hsp90 inhibitor on renal fibrosis. In TGF-beta 1-treated HK2 cells and unilateral ureteral obstruction (UUO) kidneys, we found that 17-allylamino-17-demethoxygeldanamycin (17AAG), an Hsp90 inhibitor, decreased the expression of alpha-smooth muscle actin, fibronectin, and collagen I and largely restored the expression of E-cadherin. 17AAG inhibited TGF-beta 1-mediated phosphorylation of Smad2, Akt, glycogen synthase kinase-3 beta, and extracellular signal-regulated kinase in HK2 cells. Inhibition of Hsp90 also blocked TGF-beta 1-mediated induction of snail1. This 17AAG-induced reduction was completely restored by simultaneous treatment with proteasome inhibitor MG132. Furthermore, 17AAG blocked the interaction between Hsp90 and TGF-beta type II receptor (T beta RII) and promoted ubiquitination of T beta RII, leading to the decreased availability of T beta RII. Smurf2-specific siRNA reversed the ability of 17AAG to inhibit TGF-beta 1 signaling. The effect of 17AAG on T beta RII expression and renal fibrosis was confirmed in UUO kidneys. These findings suggest that Hsp90 inhibitor prevents the development of renal fibrosis via a mechanism dependent on Smurf2-mediated degradation of T beta R11.
