Objective: To evaluate the pharmacol. effects of ginsenoside Rh2 on TGF-β1 induced activation of LX-2 cells, and to explore the mechanism of Rh2 anti-fibrosis.Methods: The hepatic fibrosis cell model was established by inducing the activation of human HSC cell line LX-2 by TGF-β1 (10 ng·mL-1).The growth curve of LX-2 cells and the toxicity of Rh2 to cells were detected by CCK-8 method.Western Blot was used to detect the relative protein expressions of α-SMA, Desmin, Vimentin, TNF-α, IL-6, IL-1β, iNOS, COX2, TNFR1, NF-κB P65, p-P65, p-IκBα, ERK, p-ERK, JNK, p-JNK, MAPK p38, and p-p38 in LX-2 cells.Results: 2.5 × 104 cells·mL-1 was used as the seeding d. of LX-2 cells, and the experiment was carried out 48 h after inoculation.The Rh2 concentration of 10 μg·mL-1 and 20 μg·mL-1 did not have effect on the viability of LX-2 cells.Different concentrations of Rh2 can inhibit the expression levels of α-SMA, Desmin, and Vimentin in LX-2 cells induced by TGF-β1 (P < 0.01), and reduce the expression levels of inflammatory factors TNF-α, IL-6, IL-1β (P < 0.05, P < 0.01).Besides, different concentrations of Rh2 can reduce the expression levels of iNOS, COX2 (P < 0.01) and regulate the expression of proteins in TNF/MAPK, NF-κB signaling pathway (P < 0.01).Conclusion: Ginsenoside Rh2 can reduce inflammatory response by regulating TNF/MAPK, NF-κB signaling pathway, thereby inhibiting TGF-β1-induced liver fibrosis in LX-2 cells.
