Abstract: The purpose of this study was to investigate the effects of peroxisome proliferators activated receptors (PPARγ) agonist (ciglitazone) and insulin on lipid metabolism and its regulatory mechanism in preadipocytes of Yanbian Yellow cattle.The experiments were divided into control group (CON,5% FBS),insulin treatment group (I,5% FBS+10 mg/L insulin),cycloglitazone treatment group (C,5% FBS+10 mg/L insulin+10 mg/L cycloglitazone) and insulin+cycloglitazone treatment group (IC,5% FBS+10 mg/L insulin+10 mg/L cycloglitazone).Each group was treated for 144 h,and transcriptome sequencing was performed on the preadipocytes by RNA-Seq technology,and the differentially expressed genes were analyzed by GO functional annotation and KEGG enrichment.Analysis results of differentially expressed genes(DEGs) in each treatment group showed that:Compared with control group,the number of DEGs in IC group was 1 764,276 and 569 more than that in I and C groups,respectively.There were 371 DEGs in each treatment group.The number of up-regulated genes in IC group was 974,140 and 249 more than that in I and C groups,respectively,while the number of down-regulated genes in IC group was 790,I and C groups was 654 and 470,respectively.The GO analysis of the DEGs showed that the DEGs in each treatment group were involved in the regulation of cellular processes,metabolic processes and biological processes.In terms of molecular function,it mainly included molecular function regulator,transport activity and transcriptional regulation activity.In terms of cell composition,most of the DEGs were enriched into organelles,membranes and extracellular regions.KEGG pathway analysis showed that the DEGs were mainly concentrated in FoxO signaling pathway,PPAR signaling pathway,TGF signaling pathway,p53 signaling pathway,etc.In conclusion,the regulation mechanism of preadipocyte differentiation of Yanbian Yellow cattle treated with insulin and cycloglazidone alone was different from that treated with cycloglazidone together,and the promotion effect of the two treatments on differentiation was more obvious.The results of this study provided a basis for studying the function and molecular mechanism of cycloglitazone and insulin in regulating fat production.
