Abstract

Activated hepatic stellate cells (HSCs) are the principal effectors during hepatic fibrosis, which is characterized by the accumulation of extracellular matrix. Therefore, present therapies and investigations into hepatic fibrosis mainly focus on the suppression of activated HSCs. Astragaloside IV (ASIV) is an effective constituent extracted from the plant Astragalus membranaceus and has exhibited anti‑fibrotic properties in hepatic fibrosis. However, its protective mechanism against hepatic fibrosis is not fully understood. The present study aimed to investigate the mechanistic role of ASIV on rat HSC‑T6 cells activated with platelet‑derived growth factor (PDGF)‑BB. HSC‑T6 cells were activated using PDGF‑BB and subsequently treated with ASIV (final concentrations of 20 and 40 µg/ml) for 48 h. ASIV treatment decreased the expression of α1 type I collagen, α‑smooth muscle actin and fibronectin on mRNA and protein levels, suggesting that ASIV suppresses PDGF‑BB‑induced HSC‑T6 activation. Senescence‑associated β‑galactosidase activity, p21, high‑mobility group AT‑hook 1 and p53, common biomarkers of senescence, were upregulated by ASIV treatment. In addition, the expression of telomerase reverse transcriptase was reduced. ASIV promoted apoptosis of PDGF‑BB‑activated HSC‑T6 cells. The NF‑κB signaling pathway, which controls cellular senescence and apoptosis, was demonstrated to be stimulated by ASIV by increasing p65, p52, p50 and inhibitor of NF‑κB kinase α expression levels, and by suppressing the expression of NF‑κB inhibitor α. Taken together, these results demonstrated that ASIV promoted cellular senescence and apoptosis by activating the NF‑κB pathway to suppress PDGF‑BB‑induced HSC‑T6 activation; with potential implications for the treatment of hepatic fibrosis.
