Spermatogenesis is regulated by the 2 pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This process is considered impossible without the absolute requirement of LH-stimulated testicular testosterone (T) production. The role of FSH remains unclear because men and mice with inactivating FSH receptor (FSHR) mutations are fertile. We revisited the role of FS...
Sex hormones regulate cholangiocyte hyperplasia in bile duct-ligated (BDL) rats. We studied whether follicle-stimulating hormone (FSH) regulates cholangiocyte proliferation. FSH receptor (FSHR) and FSH expression was evaluated in liver sections, purified cholangiocytes, and cholangiocyte cultures (NRICC). In vivo, normal female and male rats were treated with FSH or immediately after BDL with a...
A subset of ovarian tumors, referred to as sex cord-stromal tumors, produce endocrine manifestations due to the secretion of estrogens or androgens. Because gonadotropins induce the growth, differentiation, and function of the steroid-producing cells of the ovary, we hypothesized that mutations in the FSH receptor (FSH-R) might occur in this group of tumors. Ovarian sex cord tumors (n = 13), sm...
Follitropin, or follicle-stimulating hormone (FSH) receptor (FSHR), is a G protein-coupled receptor belonging to the glycoprotein hormone receptor family that plays an essential role in reproduction. Although its primary location is the gonad, the FSHR has also been reported in extragonadal tissues including bone, placenta, endometrium, liver, and blood vessels from a number of malignant tumors...
Human epidermal growth factor receptor 2 (HER2) is a transmembrane tyrosine kinase protein, Positive HER2 status has been linked with aggressive tumor behavior and resistance to cytotoxic endocrine therapies. Breast cancer complex disease the major cause of mortality in women worldwide. There are several subtypes breast many options for treatment. This study aimed know hormonal changes associat...
The follicular cells surrounding Xenopus oocyte under voltage clamp produce K(+)-current responses to follicle-stimulating hormone (FSH), adenosine (Ade), and intracellularly applied cAMP. We previously reported that these responses are suppressed by the stimulation of P2Y receptor through phosphorylation by PKC presumably of the ATP-sensitive K(+) (K(ATP)) channel. This channel comprises sulfo...
OBJECTIVE Notch is known as a transmembranous receptor family with four homologous forms - Notch 1, Notch 2, Notch 3, and Notch 4 and related to cell fate regulation and angiogenesis. The purpose is to investigate the effect of follicular stimulating hormone (FSH) on the Notch 1 expression and proliferation in ovarian cancer cells. METHODS Human ovarian cancer cell line, SK-OV-3 and FSH were ...
Elevated follicle-stimulating hormone (FSH) activity is proposed to directly cause bone loss independent of estradiol deficiency in aging women. Using transgenic female mice expressing human FSH (TgFSH), we now reveal that TgFSH dose-dependently increased bone mass, markedly elevating tibial and vertebral trabecular bone volume. Furthermore, TgFSH stimulated a striking accrual of bone mass in h...
