Nobiletin promotes adipogenesis in 3T3-L1 cells through the activation of Akt
Huimin Peng,Xiayu Tian,Lu Gan,Xiangliang Yang 경희대학교 융합한의과학연구소 2023 Oriental Pharmacy and Experimental Medicine Vol.23 No.1
The objective of the study was to investigate the effect of nobiletin on adipogenesis in 3T3-L1 cells. Here, we found that nobiletin could promote adipogenesis in 3T3-L1 cells in the absence of adipogenic inducers such as insulin, 3-Isobutyl-1-methylxanthine and dexamethasone. In addition, Real time quantitative PCR showed that the expression of adipogenic genes such as CCAAT/enhancer binding proteins, peroxisome proliferator-activated receptors-γ and fatty acid-binding protein aP2 were up-regulated in 3T3-L1 cells in the presence of nobiletin. Next, we investigated the role of Akt in the effect of nobiletin on the adipogenesis in 3T3-L1 cells by LY294002 blocking PI3K/Akt pathway. The experimental results showed that the promotive effect of nobiletin on adipogenesis was attenuated, accompanied by the down-regulation of adipogenic genes expression, after the activity of Akt was inhibited, suggesting that Akt plays an important role in the effect of nobiletin on promoting adipogenesis in 3T3-L1 cells. Still, the inhibition of Akt pathway by LY294002 was attenuated in the presence of nobiletin. These findings provide a possibility that nobiletin may be a potential candidate agent for stimulating Akt pathway in 3T3-L1 cells.
