Figure 5.
DIO Nile tilapia presented hyperleptinemia and LR. (A) Plasma Leptin levels (n = 5). (B,C) LepA mRNA levels in liver and SCAT (n = 6). (D) SOCS3, PTP1B and NPY mRNA levels in hypothalamus (n = 6). (E,F) Western blot analysis of LepA in liver and SCAT, and column diagram shows as LepA relative to GAPDH (n = 4). (G,H) IHC for LepA (brown, indicated by red arrows) in liver and SCAT. Scale bars, 50 μm. (I) Western blot analysis of p-STAT3 in hypothalamus, and column diagram is shown as p-STAT3 relative to STAT3 (n = 4). (J) Hypothalamic p-STAT3 with NtrelepA administration. (K) Food intake rate at 2 h after NtrelepA or saline treatment (n = 6). (L) 24-h weight gain after NtrelepA or saline treatment. NtrelepA group (9 ND fish, 8 HCD fish, and 9 HFD fish) and saline group (10 ND fish, 8 HCD fish, and 10 HFD fish). *p < 0.05 and **p < 0.01. Data shown as means ± SEM.
