Mechanisms of berberine affecting atherosclerotic cardiovascular diseases. Berberine has pleiotropic effects on cardiovascular diseases via multiple mechanisms. Berberine protects cardiac injury by downregulating the expression of inflammatory cytokines including IL-6, TNF-α, IL-10 and IL-17A via p38 MAPK-mediated NF-κB signaling pathways. Berberine ameliorates obesity via downregulating lncRNA Gomafu and modulating UCP1/AMPK/PGC1α signaling pathways. Berberine inhibits dyslipidemia through regulating PCSK9/LDLR pathways. Berberine suppresses atherosclerosis via activating AMPK/UCP2 signaling pathways, regulating PI3K/AKT/mTOR molecular pathways, and modulating gut microbiota. Berberine reduces cardiac fibrosis via inhibiting IGF-1R/MMP-2/MMP-9 signaling pathways. Berberine activates PPARγ to increase atherosclerotic plaque stability. Berberine ameliorates doxorubicin-induced cardiotoxicity through Sirtuin1/p66shc pathways.
