Effects of intracellular signaling pathway inhibitors on GnRH-stimulated Gh release. The primary cultured pituitary cells of intersexual ricefield eels were pre-incubated for 24 h before being treated with 100 nM of GnRH1 (A) or GnRH3 (B) in the presence or absence of inhibitors Rp-cAMPS (50 μM), U73122 (10 μM), GF109203X (20 μM), Xestospongin C (1 μM), or Nifedipine (10 μM) for 4 h, respectively. After drug treatment, culture medium was harvested for measurement of Gh release by competitive ELISA. Data were expressed as fold change relative to the vehicle control. Bars represent means ± SEM (n = 3). *P < 0.05 vs.the vehicle control.
