Then the HFD-induced NAFLD mice were treated with vitamin D. Next, the serum levels of TNF-α, GSH-px and malondialdehyde (MDA) were assessed using ELISA and ROS content was evaluated by flow cytometry, followed by the measurement of expression of Duox1, Duox2, SOD1, SOD2, PRDX1 I, ACC, SREBP1c, MTTP, PPARα, p53, p21 and p16 using RT-qPCR and Western blot analysis.
Furthermore, the levels of proteins including ACC1, FASN, SCD, and ChREBP (except SREBP-1c) increased at 24 h. These findings suggest that MEHP exposure can promote fatty acid synthesis in hepatocytes by regulating the expression of relevant genes and proteins, contributing to NAFLD.
Here, we evaluated the effect of a liver-directed allosteric inhibitor of ACC1 and ACC2 (Compound 1) on these parameters, as well as glucose and lipid metabolism, in control and diet-induced rodent models of NAFLD.
CHLZT and AICAR increased the levels of p-AMPKα and PPARγ in the NAFLD liver tissues and HepG2 cells, but decreased the levels of ACC-α, p-ACC-α, SREBP-2, and 3-hydroxyl-3-methylglutaryl-coenzyme A reductase (HMGR).
