NHA (inhibin, alpha) gene encodes the alpha subunit of inhibins A and B protein complexes that belongs to TGF-beta family. It is localized in the syncytiotrophoblast and the intermediate trophoblast of the placenta and may play a role in the mechanism of labor. INHA is also known as Inhibin α. Activin and inhibin are two closely related protein complexes involved in follicle-stimulating hormone (FSH) synthesis. They are produced in the gonads, pituitary gland, placenta, corpus luteum and other organs.
Immunogen
Synthetic peptide directed towards the N terminal region of human INHA
Application
Anti-INHA antibody produced in rabbit is suitable for western blotting at a concentration of 1μg/mL.
Biochem/physiol Actions
Inhibins facilitates the regulation of numerous cellular processes including cell proliferation, apoptosis, immune response and hormone secretion. Loss of expression of inhibinα results in high grade prostate cancer. Follicle-stimulating hormone (FSH) stimulates the secretion of inhibin from the granulosa cells of the ovarian follicles in the ovaries. In turn, inhibin suppresses FSH. Inhibin secretion is diminished by GHRH, and enhanced by insulin-like growth factor-1. Inhibin may involve competing with activin for binding to activin receptors and binding to inhibin-specific receptors. Activin, inhibin and follistatin participate as intraovarian regulatory molecules involved in follicular cell proliferation, differentiation, steroidogenesis, oocyte maturation and corpus luteum function.

To date, the only routine clinical application of inhibin or activin measurement in testing for fetal abnormalities has been the use of inhibin A in prenatal screening for trisomy 21 (Down syndrome). Second trimester maternal serum levels of inhibin A

A great deal of new information has arisen in the recent years concerning inhibin physiology and clinical relevance in reproductive medicine. It is now recognized that the two inhibin isoforms, named inhibin A and inhibin B, are produced by the
Cystic ovarian disease (COD) is an important cause of infertility in dairy cattle. Although many researchers have focused their work on the endocrine changes related to this disease, evidence indicates that intraovarian components play an important role in follicular persistence.

The cause of declining fertility with age, in women who still have regular menstrual cycles, is not clear. Follicle development, endometrial growth and hormonal patterns were evaluated in cycles of older women (aged 41-46 years; n = 26) who previously

The aim of the study was to examine, by an immunohistochemical method, the distribution of Inhibin-A and -B, in placentas from normal and pathological gestations. Sixty-two specimens of placental tissue were examined: i) ten cases from early gestations, ii) 28
