Abstract
Stress hormone is known to play a vital role in lipolysis and adipogenesis in fat cells. The present study was carried out to evaluate the effect of epinephrine on adipogenesis in the 3T3-L1 cells. The investigation on adipogenesis was done in both mono and co-cultured 3T3-L1 cells. 3T3-L1 preadipocytes and C2C12 cells were grown independently on transwell plates and transferred to differentiation medium. Following differentiation, C2C12 cells transferred to 3T3-L1 plate and treated with medium containing 10 μg/ml of epinephrine. Adipogenic markers such as fatty acid binding protein 4, peroxisome proliferator activating receptor, CCAAT/enhancer-binding protein, adiponectin, lipoprotein lipase and fatty acid synthase mRNA expressions were evaluated in the 3T3-L1 cells. Epinephrine treatment reduced adipogenesis, evidenced by reducing adipogenic marker mRNA expression in the 3T3-L1 cells. In addition, glycerol accumulation and oil red-O staining supported the reduced rate of adipogenesis. Taking all together, it is concluded that the stress hormone, epinephrine reduces the rate of adipogenesis in the mono and co-cultured 3T3-L1 cells. In addition, the rate of adipogenesis is much reduced in the co-cultured 3T3-L1 cells compared monocultured 3T3-L1 cells.
