Polypeptide hormone secreted by the hypophysis, that selectively suppresses the secretion of pituitary FSH (follicle-stimulating hormone). The molecule has two subunits (14 and 18 kD), and is a product of the gene family that includes TGF b . There are two forms, ab A and ab f573 sf B, the b subunit being shared with activin. Inhibin is now, on the basis of gene knockout experiments, considered to be a tumour-suppressor, the key gene being that for inhibin- a .
Inhibin: One of two hormones (designated inhibin-A and inhibin-B) secreted by the gonads (by Sertoli cells in the male and the granulosa cells in the female) and that inhibit the production of follicle-stimulating hormone (FSH) by the pituitary gland. The inhibins also figure in the control of gametogenesis, and embryonic and fetal development. Inh...Found on http://www.medterms.com/script/main/art.asp?articlekey=22571

Type: Term Pronunciation: in-hib′in Definitions: 1. One of several proteins that participate in differentiation and growth. Two glycoproteins, inhibin A and inhibin B, are secreted by Sertoli cells in the testis and granulosa cells in the ovary, inhibiting FSH secretion by direct action on the pituitary.Found on http://www.medilexicon.com/medicaldictionary.php?t=44609
