Body composition and metabolic characteristics of DIO Nile tilapia induced by HCD or HFD feeding. (A) Body weight changes. #HFD vs. HCD, &HCD vs. ND, #P < 0.05, &P < 0.05, ##P < 0.01 and &&P < 0.01 (n = 3, 120 fish per group). (B) Whole fish fat content (100% × fat weight/body weight, dry weight ratio) (n = 6). (C) Visceral adipose tissue-somatic index (VSI) (100 × visceral adipose tissue weight / body weight, wet weight ratio) (n = 6). (D) Liver TG content (n = 6). (E) Muscle glycogen content (n = 6). (F) Liver glycogen content (n = 6). (G–I) Plasma TG, glucose and insulin levels (n = 6). (J–L) H&E staining of liver, VAT and SCAT. Three column graphs in the right of pictures from top to bottom represent hepatocyte size, adipocyte size and thickness of SCAT, respectively. Scale bars, 100 μm. (M) PPARα and PPARγ mRNA levels in liver (n = 6). (N,O) GTT (n = 5) and ITT (n = 6). *p < 0.05 and **p < 0.01. Data shown as means ± SEM.
