Abstract | BACKGROUND: METHODS: Ob/ob mice and C2C12 cells were used to explore the effects of metformin on the morphological and physiological changes of lipid droplets. To clarify the mechanism by which metformin regulates fatty acid metabolism, a cDNA microarray and quantitative real-time PCR were used to examine the effects of metformin on the transcriptome of C2C12 cells treated with 200 micromol/L oleic acid. RESULTS:
Metformin could retard body weight gain, improve insulin sensitivity and reduce intramyocellular lipid accumulation in ob/ob mice. In C2C12 cells, metformin inhibited lipid accumulation, stimulated fatty acid oxidation, and decreased triglyceride synthesis. Twenty-seven differentially expressed genes, including 12 upregulated and 15 downregulated genes, were involved in fatty acid metabolism. Interestingly, several genes involved in acyl-CoA synthesis and fatty acid oxidation were also upregulated, such as Ppard, Acsbg1, Ascl3, and Mlycd. However, several genes related to lipolysis were downregulated, such as Ces1d and Cel. Moreover, several important genes related to lipid metabolism were also downregulated, such as Fabp4, Adipoq, and Apoc2. CONCLUSIONS:
