Rhizoma  Paridis saponins ameliorates hepatic fibrosis in rats by downregulating expression of angiogenesis‑associated growth factors.

Rhizoma Paridis saponins ameliorates hepatic fibrosis in rats by downregulating expression of angiogenesis‑associated growth factors. Mol Med Rep. 2019 Mar 05;: Authors: Han Y, Pan L, Ran S, Song Y, Sun FF, Wang YZ, Hong Y Abstract Previously, we demonstrated that Rhizoma Paridis saponins (RPS), the major active component of Rhizoma Paridis, may exhibit hepatoprotective effects. The present study aimed to identify the potential mechanism of RPS on hepatic injury and improvement in hepatic fibrosis (HF). A HF model was created in Sprague‑Dawley rats by administration of carbon tetrachloride. RPS was administered for treatment following creation of the HF model. The protein and mRNA expression of vascular endothelial growth factor (VEGF), platelet‑derived growth factor (PDGF), extracellular signal‑regulated kinase (ERK)1/2 and α‑smooth muscle actin (SMA) was detected by reverse transcription quantitative polymerase chain reaction and western blot analysis. RPS was demonstrated to improve hepatic inflammation and decrease HF severity according to hematoxylin and eosin and Masson trichrome staining. Following RPS treatment, the level of alanine aminotransferase, aspartate aminotransferase and malondialdehyde, and expression levels of the mRNA and protein of VEGF, ERK1/2, PDGF and α‑SMA in the model group was decreased. By contrast, the content of glutathione‑PX and superoxide dismutase was increased. These data sugges...
