1 The role of mitogen-activated protein kinase in insulin and insulin-like growth factor I (IGF-I) signaling cascades for progesterone and IGF-binding protein-1 production in human granulosa cells. Progesterone insulin Homo sapiens
2 Progesterone production in human granulosa cells was stimulated by insulin in a dose-related manner to 123% of the control value (P < 0.001), and IGFBP-1 production was inhibited to 25% of the baseline value (P < 0.001). Progesterone insulin Homo sapiens
3 We conclude that, under conditions of our experiments, insulin-induced stimulation of progesterone or inhibition of IGFBP-1 production in human granulosa cells does not require MAPK activation, whereas similar effects of IGF-I are largely MAPK dependent. Progesterone insulin Homo sapiens
