Objectives : The objective of this study was to investigate the effect of Myrrh 80% ethanol extract on adipocyte differentiation and adipogenesis in 3T3-L1 cell.Methods : Myrrh was prepared by extracting with 80% ethanol. Cell viability was assessed by MTT assay using 3T3-L1 cells. Anti-obesity activity was measured in lipid droplets and triglyceride (TG) accumulation in 3T3-L1 cells. We also analyzed the expression of C/EBP beta;, C/EBP alpha;, PPAR gamma;, SREBP1c, and aP2 by reverse transcriptase polymerase chain reaction (RT-PCR). In addition, we observed the production of fatty acid, acetyl-CoA carboxylase and Oil-red O stainingResults : No cytotoxicity from Myrrh 80% ethanol extracts was observed at the concentration of 1, 10, 100 ( #13197;/ #13206;) in 3T3-L1 cells. Treatment with Myrrh significantly suppressed the terminal differentiation of 3T3-L1 in a dose-dependent manner, as confirmed by a decrease in triglyceride and Fatty acid and Acetyl-CoA carboxylase. Also, Myrrh exhibited potential adipogenesis inhibition and downregulated the expression of pro-adipogenic transcription factors, such as sterol regulatory element binding protein-1c (SREBP-1c), peroxisome proliferator-activated receptor- gamma; (PPAR gamma;), CCAAT/enhancer binding proteins alpha; (C/EBP alpha;) and C/EBP beta;, and adipocyte expressed genes, such as adipocyte fatty acid binding protein (aP2) and Fas. In addition, lipid accumulation determined by Oil-red O staining showed that Myrrh extract had inhibitory effects on lipid accumulation in 3T3-L1 cells.Conclusions : These results suggest that Myrrh suppresses obesity factors in 3T3-L1 cells. Myrrh may be a useful medical herbs for attenuating metabolic diseases such as obesity. |
