To investigate the effect of Linggui Zhugan Decoction(苓桂术甘汤)on lipid metabolism in mice with nonalcoholic fatty liver disease(NAFLD), and to provide a new target and data support for clinical treatment of NAFLD.
C57BL/6J mice were used as the blank control group. ApoE-/- mice were divided into model group, Linggui Zhugan Decoction low, middle and high dose groups and simvastatin group. The blood lipid levels of mice were detected by automatic biochemical analyzer. Hematoxylin-eosin(HE)staining and oil red O staining were used to determine the degree of liver steatosis in NAFLD mice. RT-qPCR was used to detect the mRNA expressions of PI3K, AKT, FASN, SREBP1 and ATGL. The protein expressions of PI3K, AKT, p-AKT, FASN, SREBP1 and ATGL were detected by Western Blot.
After treatment with Linggui Zhugan Decoction, the serum levels of total cholesterol(TC), triglyceride(TG)and low-density lipoprotein cholesterol(LDL-C)were down-regulated(P < 0.05). The expressions of fatty acid synthesis related genes and proteins FASN and SREBP1 were decreased(P < 0.05), and the expressions of TG breakdown related genes and proteins ATGL were increased(P < 0.05). The protein expressions of PI3K and p-AKT were significantly increased(P < 0.05).
Linggui Zhugan Decoction may inhibit the occurrence and development of NAFLD by promoting the decomposition of hepatic triglyceride and inhibiting fatty acid synthesis through PI3K/AKT signaling pathway.
