The expression levels of hepatic lipogenesis and lipolysis genes in gibel carp fed with HCD and NCD during 8 weeks. (a) Expression level of hepatic acetyl-CoA carboxylase (acc, gene), (b) expression level of hepatic fatty acid synthase (fasn, gene), (c) expression level of hepatic ATP-citrate lyase (acly, gene), (d) expression level of hepatic hormone-sensitive lipase (hsl, gene), (e) expression level of hepatic carnitine palmitoyl transferase 1a (cpt1a, gene), and (f) expression level of hepatic acyl-CoA oxidase 3 (aco3, gene). Values are expressed as means ± SEMs, n = 6. ∗, ∗∗, ∗∗∗, ∗∗∗∗Different from NCD: ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.005, and ∗∗∗∗P < 0.001, NS means no significant difference (two-tailed independent t test).
