Abstract:
Liver fibrosis is a common pathological process for chronic liver injury caused by multiple etiological factors and an inevitable phase leading to liver cirrhosis. According to the previous studies, hesperidin (HDN) shows a very good protective effect on CCl4-induced chemical hepatic fibrosis in rats. In this experiment, based on the findings of the previous studies, a platelet-derived growth factor (PDGF)-induced HSC-T6 model was established to observe the inhibitory effect of HDN on HSC-T6 proliferation. The ELISA method was adopted to detect the content of collagen I in HSC-T6 supernatant. Transforming growth factor (TGF)-beta1, Smad2, Smad3, Smad7 and connective tissue growth factor (CTGF) mRNA expressions were measured by RT-PCR; TGF-beta1 and CT-GF protein expressions in HSC-T6 were determined by Western blot, in order to study HDN's effect on TGF-beta1 signaling pathway in HSC and its potential action mechanism. The results demonstrated that HDN could notably improve HSC-T6 proliferation, Collagen I growth and TGF-beta1, Smad2, Smad3 and CTGF mRNA.expressions. After being intervened with HDN, it could notably inhibit HSC-T6 proliferation and Collagen I growth, reduce TGF-beta1, Smad2, Smad3 and CTGF mRNA and TGF-beta1, CTGF protein expressions and increase Smad7 mRNA expression. HDN's antihepatic fibrosis effect may be related to the inhibition of HSC proliferation and activation by modulating TGF-beta/Smad signaling pathway.
