Abstract:

bta-miR-6523a is one of the genes related to bovine fat deposition screened by the previous research Shi Yuangang's group through sequencing data.In order to screen the target gene of bta-miR-6523a,identify its expression rule in different tissues,and explore the possible regulatory mechanism of bta-miR-6523a on bovine fat deposition,this study used a variety of database information to predict and screen the target gene of bta-miR-6523a,and enriched and analyzed the predicted functional pathway of the target gene.Finally,the expression of bta-miR-6523a in some tissues of adult cattle and calves was detected by qRT-PCR.The results showed that the predicted target genes of bta-miR-6523a were SCD,CIDEA,LIPE,etc.These predicted target genes were significantly enriched in Ras,Rap1,actin cytoskeleton regulation,Hippo and other signaling pathways related to adipocyte generation and differentiation,cytoskeleton organization and maintenance,and metabolic pathways.qRT-PCR results showed that the expression level of bovine miR-6523a was the highest in lung and the lowest in perirenal fat.The expression of bta-miR-6523a in heart and liver was significantly higher than that in subcutaneous fat,intermuscular fat,longissimus dorsi muscle and perirenal fat,but there was no significant difference among subcutaneous fat,intermuscular fat,longissimus dorsi muscle and perirenal fat.The expression of miR-6523a in subcutaneous fat,intermuscular fat and longissimus dorsi muscle of calves was significantly different,and significantly lower than that in adult bovine tissues.The high expression of bta-miR-6523a in lung tissue and lower expression in adipose tissue suggest that the biological effects of bta-miR-6523a and its target genes may be extensive.
