Abstract:

Background and aims:
Akebia Saponin D (ASD) is a major bioactive triterpenoid saponin compound isolated from the Chinese herb Dipsacus asper wall (DSW). DSW has been long used as an anti-Alzheimer disease and anti-osteoporosis agent in clinics. However, anti-atherosclerotic effects of ASD have not been fully investigated. The objective of this study is to further investigate the anti-atherosclerotic activities and mechanisms of ASD in vivo and in vitro.
Methods:
In in vitro experiments, ASD (50, 100, and 200 μM) was used to explore the effects of preventing H2O2-induced endothelial cell apoptosis and the possible mechanism involved. In in vivo experiments, ApoE-/- mice were fed a high fat diet (HFD) and treated with atorvastatin (10 mg/kg/d), ASD (50, 150, 450 mg/kg/d), or the combination therapy (atorvastatin 10 mg/kg/d and ASD 150 mg/kg/d) for 14 weeks.
Results:
We found that ASD reduced the generation of reactive oxygen species, inhibited mitochondrial membrane potential (MMP) impairment, diminished the expression of Bax and Caspase-3, increased Bcl-2 expression, and inhibited apoptosis in endothelial cells. ASD significantly increased the expression of anti-oxidant enzymes (GSH, SOD, and CAT) in both liver and vascular tissue, reduced blood lipid levels (TG, TC, and LDL-C), and decreased lipid deposition in the liver and atherosclerotic lesion size in ApoE-/- mice.
Conclusions:
Our study revealed that ASD inhibited atherosclerosis development in ApoE-/- mice by inhibiting oxidative stress-induced endothelial cell apoptosis signaling pathway, and suggested that ASD might be a potential therapeutic drug in the prevention of atherosclerosis.
