Abstract: This study was aimed to investigate the effect of ciglitazone,a peroxisome proliferator-activated receptor (PPARγ) agonist,on the adipogenic transdifferentiation of skeletal muscle satellite cells in Yanbian Yellow cattle.The skeletal muscle satellite cells were treated with ciglitazone at concentrations of 0 (CON group),5 (CL group),10 (CM group) and 20 (CH group) μmol/L for 96 h.The formation of lipid droplets was evaluated by oil red O staining and triglyceride amounts was determined by triglyceride determination kit.Real-time quantitative PCR and Western blotting were employed to detect whether adipocytogenesis related factors were involved.The results showed that the area of oil red O and the amounts of triglyceride were both significantly increased after treated with ciglitazone compared with control group (P<0.05).Moreover,the area of oil red O and the amounts of triglyceride were positively correlated with the concentration of ciglitazone.Compared with control group,the mRNA and protein expression of adipocytic transcription factors,including PPARγ,CCAAT/enhancer binding protein alpha (C/EBPα) and peripoietin-2 (PLIN2),were significantly upregulated in ciglitazone addition groups (P<0.05).However,the expression of myogenic-related factor MyoD was downregulated after treated with ciglitazone (P<0.05).The results indicated that ciglitazone could promote the transdifferentiation of skeletal muscle satellite cells to adipocytes in cattle.
