Abstract

Subcutaneous adipocytes in obese subjects have a lower sensitivity to catecholamine-induced lipolysis and a higher sensitivity to insulin anti-lipolytic effects compared to adipocytes in other adipose depots. Therefore, increasing lipolysis in subcutaneous adipocytes coupled with enhanced fatty acid oxidation may be an anti-obesity strategy. Schisandrin B (Sch B) is one of the most abundant active dibenzocyclooctadiene derivatives found in the fruit of Schisandra chinensis which is a commonly prescribed Chinese medicinal herb. We found that Sch B reduced glycerolipid contents in 3T3-L1 adipocytes and subcutaneous adipocytes dissected from DIO mice. Sch B also activated hormone sensitive lipase (HSL) and increased lipolysis in these adipocyte in a protein kinase A-dependent manner. Interestingly, Sch B increased fatty acid oxidation gene expressions in these adipocytes, implying an increase in fatty acid oxidation after treatment. In in vivo model, we found that Sch B increased HSL phosphorylation, reduced glycerolipid levels and increased fatty acid oxidation gene expressions in the subcutaneous adipocytes in the DIO mice. More importantly, Sch B significantly reduced the subcutaneous adipocyte sizes, subcutaneous adipose tissue mass and body weight of the mice. Our study provides scientific evidence to suggest a potential therapeutic function of Sch B or Schisandra chinensis seed containing Sch B in reducing obesity.
