2003 FEB 6 - (NewsRx.com & NewsRx.net) -- Scientists report bone morphogenetic protein-15 regulates only one of a few hormones associated with human reproduction and may thus be a fertility modulator.

According to a study from the United States, "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 FSH-beta subunit transcription in LbetaT2 cells without affecting LH-beta and GnRH receptor transcription," stated F. Otsuka and coauthors, University of California San Diego, School of Medicine.

"These findings, therefore, suggest a possible autocrine control mechanism selective for FSH-beta synthesis by BMP-15. Moreover, BMP-15 exerts a potent and selective stimulation of FSH, but not LH, secretion by primary pituitary cells."

"Taken together, we hypothesize that BMP-15 could play a physiological role in the monotropic rise ...
