Abstract:

This study aims to screen the differentially expressed genes in perirenal fat of Simmental cattle and Angus cattle,and analyze the differences in serum indexes between the two breeds,in order to determine the lipid metabolism and endocrine function of perirenal fat,so as to lay a foundation for cattle breed selection.Three Simmental cattle and three Angus cattle of the same age were selected,and fasting blood was collected before feeding to separate and for determination of serum biochemical indexes.After slaughter,perirenal fat of the same size was sampled,and total RNA was extracted for transcriptome sequencing analysis.The differentially expressed genes(DEGs)were identified using the DEGseq method,and GO and KEGG analysis were performed.The sequencing results were verified using Real-time fluorescence quantitative PCR.The results showed that:the serum contents of albumin(ALB2),urea nitrogen(UREAL)and glucose(GLUC3)in Angus cattle were significantly lower than that of Simmental cattle(P<0.05),and the contents of triglyceride(TRIGL)were significantly higher than that of Simmental cattle(P<0.05).Transcriptome results showed that 1 743 genes were differentially expressed between the perirenal fats of two breeds.Among that,1 361 and 382 genes were up regulated and down regulated,respectively.GO analysis showed that DEGs were significantly enriched to 52 biological functions,which were mainly related to cellular processes and cells.KEGG analysis showed that DEGs were significantly enriched mainly in fat digestion and absorption,cAMP,PPAR and Rap1 signaling pathways.Five genes(SCD5,APOA4,PTX3,OLR1 and PRKCZ)related to lipid metabolism were identified,and the sequencing results of these five genes were verified by Real-time fluorescence quantitative PCR,these results indicated that the sequencing results were reliable and the obtained differential genes could be used as basic data for breeding beef cattle breeds.
