The effects of Ganoderma lucidum herba pharmacopuncture on 3T3-L1 preadipocyte differentiation

Abstract

Objective : The purpose of this study is to investigate the effects of Ganoderma lucidum herba pharmacopuncture (GHP) on the adipogenesis in 3T3-L1 preadipocytes. Methods : 3T3- L1 preadipocytes were differentiated with adipogenic reagents by incubating for 2 days in the absence or presence of GHP ranging from 1 and 2%. The effect of GHP on cell proliferation of 3T3-L1 preadipocytes was investigated using MTT assay. The effect of GHP on adipogenesis was examined by Oil red O staining and measuring glycerol-3-phosphate dehydrogenase (GPDH) and intracellular triglyceride (TG) content. Results : Following results were obtained from the preadipocyte proliferation and adipocyte differentiation of 3T3-L1. We observed no effect of GHP on preadipocyte proliferation. GHP inhibited adipogenesis, the activity of GPDH and accumulation of intracellular TG content. Conclusions : These results suggest that GHP inhibit differentiation of preadipocyte.
