A Novel Function of Bone Morphogenetic Protein-15 in the Pituitary: Selective Synthesis and Secretion of FSH by Gonadotropes

Abstract excerpt

Bone morphogenetic protein-15 (BMP-15) has been known to be an oocyte-specific factor and regulate granulosa cell functions. Here, we report that BMP-15 is also expressed in the well established gonadotrope cell line, LbetaT2 and mouse pituitary tissue. Interestingly, BMP-15 stimulates FSHbeta subunit transcription in LbetaT2 cells without affecting LHbeta and GnRH receptor transcription. These findings,...
