Effect of Pirfenidone on renal interstitial fibrosis in rats
摘要
Abstract
Objective To investigate the effect of Pirfenidone (PFD) on renal interstitial fibrosis in rat model of unilateral ureteral occlusion (UUO) and to reveal the anti-fibrosis mechanism of PFD.Methods Twenty-four standard male SD rats were randomly divided into three groups:normal control group (N),UUO model group (M) and Pirfenidone treated group (S).The rats of the M and S groups underwent left urethral ligation to make the renal interstitial fibrosis model.The S group was given PFD 250 mg/(kg·d) for gavage,meanwhile the N and M groups were given 1% sodium carboxymethyl cellulose solution for gavage.Two rats were sacrificed from each group on day 1,3,5 and 7 after UUO operation,the kidney of the obstructive side was taken for further research.In each group,pathological changes were observed by HE staining,qRT-PCR was applied to detect the mRNA expression of connective tissue growth factor (CTGF),Western bolt was applied to detect the protein expressions of TGF-β and α-SMA.Results There was obvious renal interstitial fibrosis in the M group.Compared with the N group,the expressions of TGF-β and α-SMA proteins and the mRNA expression of CTGF were significantly increased in the M group(P < 0.05).Compared with the M group,the expressions of above parameters in the S group were decreased significantly (P < 0.05).The level of TGF-β was positively correlated with the level of α-SMA (P < 0.05).Conclusions Pirfenidone has anti-fibrosis effect on rat UUO model by inhibiting renal TGF-β and CTGF expressions,which may control the fibroblast transformation and reduce the extracellular matrix deposition in the renal tissue.关键词
