Abstract:

The aim of this study was to explore the role and related mechanism of ACSBG2 gene, a member of acyl-CoA synthetase family, in the response of goose liver to changes in nutritional status. In this study, 10-day-old healthy Landes geese (n=8) were used in the fasting/refeeding model, and 65-day-old Landes geese (n=6) were used in the overfeeding model. Firstly, these animal models were used to determine the response of ACSBG2 mRNA expression in goose liver and pectoral muscle to changes in nutritional status. Secondly, the effects of nutrition-related factors (glucose, insulin, sodium oleate, palmitic acid) on the mRNA expression level of ACSBG2 in goose primary hepatocytes and pectoral myocytes were determined. Then, ACSBG2 gene was overexpressed in goose primary hepatocytes and transcriptome sequencing analysis was performed to identify the downstream genes and pathways regulated by ACSBG2, which was followed by determining the mRNA expression level of ACSBG2 downstream genes in vitro and in animal models. The results showed that: 1) The expression of ACSBG2 in the liver was inhibited by fasting (P < 0.01) and induced by refeeding and overfeeding (P < 0.001). The expression of ACSBG2 in pectoral muscle was induced by refeeding (P < 0.001) and overfeeding (P < 0.01). 2) The expression of ACSBG2 in goose primary hepatocytes was inhibited by sodium oleate (P < 0.05) and palmitic acid (P < 0.001), but induced by glucose (P < 0.01) and insulin (P < 0.001). The expression of ACSBG2 in goose primary pectoral cells was inhibited by glucose (P < 0.05) and palmitic acid (P < 0.05), but induced by sodium oleate (P < 0.001). 3) The differentially expressed genes affected by ACSBG2 overexpression were mainly enriched in steroid hormone synthesis and cell adhesion-related pathways. 4) ACSBG2 may mediate the effect of changes in nutritional status on STX1A gene expression in vitro and animal models. In summary, ACSBG2 gene mainly regulates glycolipid metabolism and the expression of inflammation-related factors through steroid hormone synthesis and cell adhesion-related pathways, thereby mediating the effects of nutritional/energy changes.
