We have characterized the in vivo actions of human wild-type FSH receptor (FSHR) overexpressed in Sertoli cells of transgenic (Tg) mice (TgFSHRwt) compared with transgenic overexpression of the human activated mutant FSHR*D567G (TgFSHR*D567G). Testicular TgFSHRwt expression significantly elevated specific FSH binding (>2-fold, P < 0.01) relative to nontransgenic testes, similar to increased FSH...
Patient A was a 30-year-old white woman with a longstanding history of primary amenorrhea and infertility. By age 18 the patient had neither menstruated nor demonstrated evidence of normal breast development. At that time she was given oral contraceptives for four cycles and responded with normal vaginal bleeding. Laboratory evaluation at age 18 demonstrated a serum FSH (follicle-stimulating ho...
An ovulatory hCG stimulus to rhesus macaques undergoing controlled ovarian stimulation protocols results in a rapid and sustained increase in progesterone synthesis. The use of lipoproteins as a substrate for progesterone synthesis remains unclear, and the expression of lipoprotein receptors [very-low-density lipoprotein receptor (VLDLR), low-density lipoprotein receptor (LDLR), and scavenger r...
Immature calf testes were found to be an unusually rich source of follitropin (FSH) receptors. Particulate fractions derived from such testes bound 32% of added biologically active radiolabeled human FSH (12”I-labeled hFSH) and had a binding capacity of 52 x lo-l4 mol/mg of protein. These values are considerably higher than those previously reported for FSH receptors in other types of beef or m...
The present study was aimed at determining whether insulin-like growth factor-1 (IGF-1) is a component of fetal bovine serum (FBS) that enables porcine cumulus cells to expand in response to FSH in vitro. Cumulus-oocyte complexes (COC) obtained from 4- to 6-mm follicles of prepubertal gilts were cultured at 39 degrees C for 24 h in media that contained human recombinant IGF-1 (50 ng/ml), FBS (1...
