Effect of Shenge Recipe on oxidative stress and mitochondrial function of steatosis hepatocytes
Objective,2,To explore the mechanism of Shenge Recipe on inhibiting oxidative stress and mitochondrial function of steatosis hepatocytes.,Methods,2,①Thirty male C57BL/6J mice were divided into normal group, model group and Shenge Recipe group (the dosage of 15.75 g·kg,-1,·d,-1,), with 10 mice in each group. The fatty liver model was induced by methionine and choline deficiency (MCD) diet for 16 weeks, while the mice in the Shenge Recipe group was given intragastric administration of traditional Chinese medicine since the 13th week. The levels of liver inflammation, lipid deposition and peroxidation were observed. ②Human hepatoma cells (HepG2 cells) were pretreated with palmitic acid (PA,0.2 mmol/L) for 24 h to induce hepatic steatosis model. Then the cells were treated with silencing information regulatory protein 3 (SIRT3) inhibitor (3-TYP), adenylate activated protein kinase (AMPK) inhibitor (Compound C), Shenge Recipe drug serum and normal mouse serum and were divided into 7 groups: Control group (Control), model group (PA), Shenge Recipe group (PA+SGF), SIRT3 inhibition group (PA+3-TYP), AMPK inhibition group (PA+CMC), Shenge Recipe+SIRT3 inhibition group (PA+3-TYP+SGF) and Shenge Recipe+AMPK inhibition group (PA+CMC+SGF). The levels of oxidative stress including cellular reactive oxygen species (ROS), malondialdehyde(MDA), mitochondrial function including adenosine triphosphate (ATP) and their effects on the contents of SIRT3, p-AMPK/AMPK and oxisome proliferator activated receptor γ coactivator-1α (PGC-1α) were observed. The structure of mitochondria was observed under electron microscope.,Results,2,①Compared with PA, the levels of lipid deposition and peroxide in PA+SGF were all reduced. ②Compared with PA group, the levels of TG, TNF-α and IL-6 in PA+SGF group were decreased significantly (,P,<,0.05). And the levels of ROS and MDA were decreased as well(,P,<,0.01), while PGC-1α and ATP levels showed the increase in PA+SGF group (,P,<,0.05). The damage of mitochondria was alleviated under electron microscope. However, the above effects were weakened after treatment with 3-TYP and Compound C.,Conclusion,2,Shenge Recipe can inhibit oxidative stress injury, improve mitochondrial function and reduce hepatocyte steatosis, and its mechanism may be related to up-regulating the expression of SIRT3 and AMPK.
