Receptor specificity of E2-induced follicle-stimulating hormone (FSH)β and growth regulation by estrogen in breast cancer 1 (GREB1) mRNA expression. (A) Effects of ER agonists on FSHβ and GREB1 mRNA expression. Pituitary cells were treated for 24 h with E2 (10 nM), G protein-coupled estrogen receptor (GPER) agonist G-1 (1 µM), estrogen receptor alpha agonist propylpyrazole triol (PPT) (1 µM), and ERβ agonist DPN (1 µM), respectively. (B) Effects of GPER antagonist G-15 and ER antagonist ICI182780 on E2-induced FSHβ and GREB1 mRNA expression. Pituitary cells were treated for 24 h with E2 (10 nM) in the presence or absence of the G-15 (10 µM) or ICI182780 (10 µM), respectively. (C) Effects of GPER antagonist G-15 or ER antagonist ICI182780 on G-1- or DPN-induced FSHβ or GREB1 mRNA expression. Grass carp pituitary cells were incubated for 24 h with GPER agonist G1 (1 µM) in the presence or absence of G-15 (10 µM), or ERβ agonist DPN (1 µM) in the presence or absence of ICI182780 (10 µM).
