Fig. 8From: Regulation by FSH of the dynamic expression of retinol-binding protein 4 in the mouse ovarySchematic overview of the proposed pathway involved in the induction of Rbp4 by FSH. FSH binds to its receptor (FHR) and elevates cAMP levels, which activates PKA. PKA then stimulates the expression of HMGA1, SF-1, and LRH-1, and promotes Rbp4 transcriptionBack to article page
