Fig. 3From: Rhein alleviates renal interstitial fibrosis by inhibiting tubular cell apoptosis in ratsEffect of rhein on the phosphorylation levels of STAT3 in the kidney of UUO model rats. a Western blot analysis of the kidney tissue lysates of sham and UUO rats with vehicle (veh) or rhein treatment, using antibodies against STAT3, p-STAT3 and GAPDH (as loading control). b Quantification of the Western blot results in a by densitometry, expressed as fold-increase over the controls. Data were shown as mean ± SD. **p < 0.01, compared to UUO + veh/STAT3. #p < 0.05, compared to UUO + veh/p-STAT3Back to article page
