Fig. 2. Expression levels of LHβ and FSH mRNA in the primary culture of pituitary cells (black bars) and whole pituitaries (grey bars) incubated with different concentrations of NKB peptide.

(A) FSHβ levels in female Nile tilapia, (B) LHβ levels in female Nile tilapia, (C) FSHβ levels in male Nile tilapia, (D) LHβ levels in male Nile tilapia. *Indicates significant difference (p<0.05) from control group. FSH, follicle stimulating hormone; LH, luteinizing hormone; NKB, neurokinin B.
