Decabromodiphenyl ether disturbs hepatic glycolipid metabolism by regulating the PI3K/AKT/GLUT4 and mTOR/PPAR gamma/RXR alpha pathway in mice and L02 cells
Decabromodiphenyl ether (BDE-209) is a persistent environmental pollutant that poses great risks to human health and has been associated with glucose and lipid metabolism. However, the mechanisms by which BDE-209 disturbs glycolipid metabolism in the liver remain unclear. Therefore, this study sought to confirm the effects of BDE-209 on glycolipid metabolism in mice livers and L02 cells to elucidate potential mechanisms of action. In vivo BDE-209 exposure caused histological damage and lipid accumulation, elevated glucose, low-density lipoprotein, total cholesterol, and triglyceride levels, and decreased glycogen and high-density lipoprotein levels in mice livers. Moreover, in vitro BDE-209 exposure not only induced L02 cells cytotoxicity (i.e., reduced cell viability and increased LDH leakage and ROS generation) but also increased glucose and triglyceride concentrations in L02 cells. Furthermore, IdF-1, an activator of the PI3K-AKT pathway, markedly inhibited BDE-209-incluced glucose concentration increase in L02 cells and antagonized the inhibitory effect of BDE-209 on the PI3K/AKT/GLUT4 pathway by counteracting the changes in the expression levels of p-IRS, AKT, Pl3K, p-AKT, and GLUT4. Moreover, GW9662, a PPAR gamma inhibitor, blocked lipid accumulation and the upregulation of the mTOR/PPAR gamma/RXRa. pathway in L02 cells induced by BDE-209 by relieving the increases in p-mTOR, PPAR gamma, and RXR alpha protein expression levels. In summary, this study revealed that BDE-209 disrupted glycol ipid metabolism by inhibiting the Pl3K/AKT/GLUT4 pathway and activating the mTOR/PPAR gamma/RXR alpha pathway. (C) 2020 Elsevier B.V.
