Abstract:

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Paeoniflorin, a natural product and active ingredient of Paeonia lactiflora, has been demonstrated to have many pharmacological effects including antiinflammatory and antihyperglycemic activity. We investigated the effects of paeoniflorin on NAFLD in mice and its underlying mechanisms. We examined this hypothesis using a well-established animal model of NAFLD. The effects of paeoniflorin on inflammation and glucolipid metabolism disorder were evaluated. The corresponding signaling pathways were measured using real-time polymerase chain reaction (PCR). We demonstrated that the mice developed obesity, dyslipidemia, and fatty liver, which formed the NAFLD model. Paeoniflorin attenuated NAFLD and exhibited potential cardiovascular protective effects in vivo by lowering body weight, hyperlipidemia, and insulin resistance; blocking inflammation; and inhibiting lipid ectopic deposition. Further investigation revealed that the antagonistic effect on hyperlipidemia and lipid ectopic deposition was related to lowering the lipid synthesis pathway (de novo pathway, 3-hydroxy-3-methyl glutaryl coenzyme A reductase (HMG-CoAR)), promoting fatty acid oxidation [peroxisome proliferator-activated receptor-alpha (PPARα), carnitine palmitoyltransferase-1, etc.] and increasing cholesterol output (PPARγ-liver X receptor-α-ATP-binding cassette transporter-1); the inhibitory effects on inflammation and hyperglycemia were mediated by blocking inflammatory genes activation and reducing gluconeogenic genes expression(phosphoenolpyruvate carboxykinase and G6Pase). These results suggest that paeoniflorin prevents the development of NAFLD and reduces the risks of atherosclerosis through multiple intracellular signaling pathways. It may therefore be a potential therapeutic compound for NAFLD.
