The inhibition of C3 in GFL is mainly attributed to hyperinsulinemia, hyperlipidemia and the uniqueness of goose liver cells. Complement C3 not only affects hepatic steatosis but also influences inflammation/immune response in GFL.
Non-alcoholic fatty liver disease (NAFLD) occurs in humans, domestic animals and poultry. Different from upregulation of complement C3 in human NAFLD, C3 expression is inhibited in goose fatty liver (GFL), implying a specific role of C3 in GFL. This study was mainly focused on uncovering the uniqueness of goose liver cells in the regulation of C3 expression and identifying the downstream genes of C3 to improve understanding on the specific role of C3 in GFL. The results showed that C3 expression was inhibited in the liver, muscle and fat tissues of the overfed versus control (normally fed) geese. Oleate and insulin could inhibit C3 expression in goose primary hepatocytes but induce it in mouse primary hepatocytes. A total of 1,123 differentially expressed genes (DEGs) were affected by C3 overexpression and were mainly enriched in immune response/inflammation and catabolism-related KEGG pathways. Additionally, the representative downstream genes (FASN and ETNK1) of C3 could mediate the role of C3 in the development of GFL. In conclusion, the suppression of C3 in GFL is at least partially attributed to hyperinsulinemia, hyperlipidemia and uniqueness of goose liver cells. Complement C3 does not only affect hepatic steatosis but also affect inflammation/immune response in GFL.
