1,3,5,8-tetrahydroxyxanthone regulates ANGPTL3-LPL pathway to lessen the ketosis in mice

Ketosis is a metabolic disorder closely associated with both lipid and carbohydrate metabolism. Recent studies show that angiopoietin-like protein 3 (ANGPTL3) contributes to the development of metabolic disorder. The objective of this study was to explore the inhibitory effect of 1,3,5,8-tetrahydroxyxanthone (Xan), a naturally occurring flavonoid compound, on ketosis and the mechanisms involved in this regulation. After 4weeks, Xan (10 or 30mg/kg, intragastrically) treatment decreased plasma total ketone bodies, malondialdehyde, 8-isoprostane, triglyceride, total cholesterol levels, and hepatic ANGPTL3 expression concomitantly with increased plasma glucose concentration and adipose lipoprotein lipase (LPL) expression in ketosis murine. The present results suggest that Xan regulates ANGPTL3-LPL pathway to lessen the ketosis in mice.
