Catalpol induces autophagy and attenuates liver steatosis in ob/ob and high-fat diet-induced obese mice

Figure 1. CAT ameliorated hepatic steatosis in ob/ob mice. Eight week-old ob/ob mice were treated with CAT (50 mg/kg/d) or vehicle by oral gavage for 4 weeks. (A) Gross images of liver tissue and changes in liver and body weights. (B) Serum TG and TC levels. (C) Liver TG and TC content normalized to total protein. (D) Representative photomicrographs of liver sections stained with H&E and Oil Red O. Scale bars: 50 μm. (E) mRNA expression levels of hepatic lipogenic genes ACC1α and FAS and fatty acid oxidation genes PPARα and CPT1. Data are expressed as fold-change relative to vehicle-treated ob/ob mice. (F) Representative western blot analysis of LC3-II, Sqstm1/P62, and Becn1 proteins. Unpaired two-sided t-tests were used for statistical comparisons to controls. *P < 0.05, **P < 0.01, ***P < 0.001 vs. vehicle-treated ob/ob mice.
