Metabolomics of the Protective Effect of Ampelopsis grossedentata and Its Major Active Compound Dihydromyricetin on the Liver of High-Fat Diet Hamster.
In this study, we first analyzed the chemical compounds of AG by HPLC-DAD-ESI-IT-TOF-MS n . Of the 31 compounds detected, 29 were identified based on previous results. Then, the effects of DMY and AG on high-fat diet hamster livers were studied and the metabolite levels and metabolic pathway activity of the liver were explored by 1H NMR metabolomics. Compared to the high-fat diet group, supplementation of AG and DMY attenuated the high-fat-induced increase in body weight, liver lipid deposition, serum triglycerides and total cholesterol levels, and normalized endogenous metabolite concentrations. PCA and PLS-DA score plots demonstrated that while the metabolic profiles of hamsters fed a high-fat diet supplemented with DMY or AG were both far from those of hamsters fed a normal diet or a high-fat diet alone, they were similar to each other. Our data suggest that the underlying mechanism of the protective effect of DMY and AG might be related to an attenuation of the deleterious effect of high-fat diet-induced hyperlipidemia on multiple metabolic pathways including amino acid metabolism, ketone body metabolism, energy metabolism, tricarboxylic acid cycle, and enhanced fatty acid oxidation.

Hippocrates (460-371 bc) first recognized the relationship between the neuropsychological and physiologic changes observed in liver disease (Figs. 1 and 2). At that time, Hippocrates noted that there was a poor clinical outcome associated with delirium that was preceded by jaundice.1
Athletic performance and physique have been closely associated with diet and nutrition for ages. One such diet is the ketogenic diet, increasingly favored by many athletes.ACC.org

Absence of Bmp8b reduces liver inflammation and fibrosis in the NASH model (WD). In the acute (3days) CCl4 model, absence of B mp8b impacts acute inflammatory responses, hepatic stellate cells (HSC) activation, and compensatory hepatocyte proliferation; defective inflammatory pathway...
