Leukemia inhibitory factor induces the chemomigration of immortalized gonadotropin-releasing hormone neurons through the independent activation of the Janus kinase/signal transducer and activator of transcription 3, mitogen-activated protein kinase/extracellularly regulated kinase 1/2, and phosphatidylinositol 3-kinase/Akt signaling pathways.


Leukemia inhibitory factor (LIF) is a pleiotropic cytokine of the IL-6 superfamily. LIF acts through a cell-surface receptor complex formed by two subunits, the specific LIF receptor beta (LIFRbeta) and the glycoprotein 130. Little is known about LIF involvement in modulating the neuroendocrine circuitry governing the reproductive function and, specifically… (More)
