RESUMEN

Objective:To explore the expression and role of AQP9 in the models of cultured steatosis hepatocytes.Methods:Steatosis models of hepatocytes was established by adding oleic acid to the growing L-02 cell strain.The expression of AQP9 mRNA was measured with RT–PCR and the protein expression of AQP9 were measured by Western blotting.Lipid droplets in the hepatocytes were observed by oil red staining and the contents of triglyceride,FFA and glycerol in hepatocytes were measured with analyzed kit.Results:Through oil red staining.a few lipid droplets were observed at 24h and steatosis hepatocyte increased greatly at 72h.Triglyceride,FFA and glycerol contents in hepatocytes of model groups also increased,as compared with the control group(P

RESUMEN

Objective To explore the effects of TNF alpha on the expression of sterol-regulatory element binding protein-1c, SREBP-1c mRNA and the content of triglyceride (TG) in the models of cultured steatosis hepatocytes. Methods Steatosis models of hepatocytes were established by adding oleic acid to the growing L-02 cells, and then cultured in present with TNF alpha or its antibody. The expressions of SREBP-1c and fatty acid synthetase (FAS) mRNA were measured with RT-PCR, lipid droplets in the hepatocytes were observed with oil red staining and the TG contents in hepatocytes were measured with analyzed kit. Results SREBP-1c mRNA was upregulated in the TNF alpha treatment group in comparison with the normal control group(P
