Follicle-Stimulating Hormone Stimulates Circulating Gonadotropin Surge-Attenuating/Inhibiting Factor Bioactivity in Cows1

Control of gonadotropin secretion by follicle-stimulating hormone-releasing factor, luteinizing hormone-releasing hormone, and leptin.

Fractionation of hypothalamic extracts on a Sephadex G-25 column separates follicle-stimulating hormone-releasing factor (FSHRF) from luteinizing hormone-releasing hormone (LHRH). The FSH-releasing peak contained immunoreactive lamprey gonadotropin-releasing hormone (lGnRH) by radioimmunoassay, and its activity was inactivated by an antiserum specific to lGnRH. The identity of lGnRH-III with FS...

Pituitary transcription factor Prop-1 stimulates porcine follicle-stimulating hormone beta subunit gene expression.

Molecular cloning of the transcription factor that modulates the expression of porcine follicle-stimulating hormone beta subunit (FSHbeta) gene was performed by the yeast one-hybrid cloning system using the -852/-746 upstream region (Fd2) as a bait sequence. We eventually cloned a pituitary transcription factor, Prop-1, which has been identified as an upstream transcription factor of Pit-1 gene...

Bioactive Follicle-Stimulating Hormone

Specific and sensitive in vitro bioassays suitable for measurement of follicle-stimulating hormone (FSH) in small quantities of serum and urine have recently been validated. Comparisons of bioassay (B-FSH) potencies with immunoassay (I-FSH) estimates and chromatofocusing patterns have facilitated new discoveries regarding the regulation of FSH biosynthesis, storage, secretion, serum concentrati...
