SENSIBILITY OF OVARY TO GONADOTROPIN

Gonadotropin Signaling in the Ovary

Receptor-Mediated Gonadotropin Action in Ovary

The effect of gangliosides and cholera enterotoxin on 1251 choriogonadotropin binding, cAMP formation, protein kinase activation and progesterone production have been studied in isolated rat ovarian interstitial cells. A close correlation was observed between the amount of adenosine 3' : 5'monophosphate (CAMP) produced in the cells and the extent of the activation of protein kinase in response ...

Characterization of the inappropriate gonadotropin secretion in polycystic ovary syndrome.

To evaluate gonadotropin release in polycystic ovary syndrome (PCO), one or more of the following hypothalamic-pituitary function tests were performed on 24 patients with the syndrome. These tests included (a) the pulsatile pattern and day-to-day fluctuation of gonadotropin release; (b) effects of exogenous estrogen and antiestrogen (clomiphene) administration on gonadotropin release; and (c) p...

P-234: Expression of Human Chorionic Gonadotropin (hCG) Hormone Using Chinese Hamster Ovary Cells

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

Binding of radio . . iodinated gonadotropin to the ovary of exotic carp (

Heterologous murre! gonadotropic hormone (m-GtH) binds to common carp oocyte plasma membrane and enhances steroid secretion. With increasing concentration of radio-labelled hormone the receptor binding is also found to increase linearly up to a certain concentration and then decrease. The [1 !] murre! GtH binding characteristics to a preparation of common carp ovarian plasma membrane shows satu...
