Abstract
- Angelica sinensis polysaccharide (ASP) has presented increasingly recognized lipid regulation and antioxidant abilities. However, there is little direct evidence to explain why ASP possesses the observed lipid-lowering and anti-oxidation effects. In vivo and in vitro models of alcoholic fatty liver disease (AFLD) were established to examine the direct effect of ASP on hepatic fat accumulation. Our results showed that the lipid-lowering effect of ASP might result from the dual inhibition of lipid synthesis and CD36-mediated lipid uptake. The antioxidation of ASP might be attributed to the reversal of alcohol metabolic pathways from CYP2E1 catalysis to ADH catalysis. Taken together, the study demonstrated the direct role of ASP in lipid metabolism for the first time and revealed the underlying mechanism of reducing ROS, providing an available strategy for ASP as a potential agent to treat AFLD. [Display omitted] • The improvement effect of ASP on AFLD was confirmed for the first time. • ASP could reduce the hepatic levels of ACC and FAS to suppress lipid synthesis. • ASP could return hepatic CD36 content to normal levels to inhibit lipid uptake. • ASP could promote alcohol metabolism by enhancing ADH pathway in AFLD mice.
