Adenosine-rich extract of Ganoderma lucidum: A safe and effective lipid-lowering substance

Ganoderma lucidum is a traditional Chinese medicine with a variety of active compounds and possesses adequate lipid-lowering and anti-atherosclerotic effects. However, its main active components and potential mechanisms still remain unclear. Here, we evaluated the anti-hyperlipidemic effect of the adenosine extract from Ganoderma lucidum (AEGL) in high-fat-diet (HFD)-induced hyperlipidemic ApoE−/− mice and explored the underlying biological mechanism by multi-omics analysis. Treatment with AEGL for 8 weeks significantly decreased the serum levels of total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-c) by 45.59%, 41.22%, and 39.02%, respectively, as well as reduced liver TC and TG by 44.15% and 76.23%, compared with the HFD-only group. We also observed significant amelioration of hepatic steatosis without liver and kidney damage after AEGL treatment. Regulating the expression and acetylation/crotonylation of proteins involved in the PPAR signaling pathway may be one of the potential mechanisms involved in the observed lipid-lowering effects of AEGL.
