초록
In this study, the effects of Ganoderma lucidum (GL) on fat metabolism were performed in 3T3-L1 adipocytes. The effects of GL on 3T3-L1 preadipocytes differentiation were also examined. Our results showed that GL decreased the TG content by ORO staining. To elucidate the mechanism of the effects of GL on lowering TG content in 3T3-L1 adipocytes, we examined whether GL modulate the expressions of transcription factors and adipokines related to control of energy expenditure process because adipokines regulate adipocyte mass and increased expenditure may consume much TG in adipocytes. As a result, the expression of C/EBPβ, C/EBPδ, C/EBPα, and PPARγ genes, which induce the adipose differentiation and adipose-specific FAS, aP2, and adipsin genes, which compose fat formation were decreased. In addition, GL increased the expression of leptin, UCP2, adiponectin in 3T3-L1 adipocytes, resulting in energy homeostasis. In conclusion, GL could regulate transcript factor related to induction of adipose differentiation and control TG content by up-regulation of adipokines related to fat burn.
