BACKGROUND The follicle-stimulating hormone receptor (FSH-R) is a seven transmembrane spanning receptor (7TMR) which plays a crucial role in male and female reproduction. Upon FSH stimulation, the FSH-R activates the extracellular signal-regulated kinases (ERK). However, the mechanisms whereby the agonist-stimulated FSH-R activates ERK are poorly understood. In order to activate ERK, some 7 TMR...
In newborn rats the levels of nerve growth factor (NGF) mRNA (mRNANGF) and NGF receptor mRNA (mRNA(rec)) in the sciatic nerve were 10 and 120 times higher, respectively, than in adult animals. mRNA(rec) levels decreased steadily from birth, approaching adult levels by the third postnatal week, whereas mRNANGF levels decreased only after the first postnatal week, although also reaching adult lev...
OBJECTIVE To detect the presence of antibodies to the proacrosin/acrosin system and to evaluate their effect on the sperm acrosomal protein activities in women consulting for infertility. DESIGN Retrospective study. SETTING Basic research laboratory. PATIENT(S) Recombinant proteins derived from human proacrosin (Rec-40, Rec-30, Rec-20, Rec-10) and recombinant human zona pellucida (ZP) gly...
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...
در مطالعه حاضر اثرات تزریق گنادوتروپین سرم مادیان آبستن (pmsg) به همراه هورمون محرک رشد فولیکولی (fsh) و هورمون آزادکننده گنادوتروپین (gnrh) بر رشد فولیکولی و برهزایی میشهای نژاد افشاری مورد بررسی قرار گرفت. چرخه فحلی 80 راس میش نژاد افشاری چندشکم با میانگین وزنی 5/2± 68 و bcs 5/3-5/2، با استفاده از سیدرهای پروژسترونی 14 روزه همزمان سازی شد. 400 واحد از گنادوتروپین سرم مادیان آبستن (pmsg) همز...
In the present study, oral supplementation of l-arginine in rats was evaluated for its anti-stress and adaptogenic activity using the cold (5 degrees C)-hypoxia (428 mmHg)-restraint (C-H-R) animal model. A dose-dependent study of l-arginine was carried out at doses of 12.5, 25.0, 50.0, 100.0, 200.0 and 500.0 mg/kg body weight, administered orally 30 min prior to C-H-R exposure. The time taken b...
Renal endothelial cells (REc) are the first target of HIV-1 in the kidney. The integrity of REc is maintained at least partially by heparin binding growth factors that bind to heparan sulfate proteoglycans located on their cell surface. However, previous studies showed that the accumulation of two heparin-binding growth factors, Vascular Endothelial Cell Growth Factor-A (VEGF-A) and Fibroblast ...
The procedure for the selection of a temperature-sensitive recombination mutant in Drosophila is described. Use of this procedure has led to the recovery of three alleles at a new recombination locus called rec-Z, located within the region of chromosome 3 circumscribed by Deficiency(3R)~bd'~~. One allele, rec-Z26, is temperature sensitive, and the other two alleles, rec-Z6 and rec-1I6, are temp...
Transcripts and protein for follicle-stimulating hormone receptor (FSHR) were demonstrated in abdominal adipose tissue of female chickens. There was no expression of the Fsh gene, but FSH and FSHR colocalized, suggesting that FSH was receptor bound. Partial correlations indicted that changes in abdominal fat (AF) content were most directly correlated with Fshr mRNA expression, and the latter wa...
هورمون محرک فولیکول گاوی (fsh) به خانواده هورمون های گلیکوپروتئینی تعلق دارد که از غده هیپوفیز یا جفت ترشح می شوند. این هورمون یک هترو دایمر می باشد که از زیر واحد آلفا (مشترک در همه هورمون های گلیکوپروتئینی) و زیر واحد بتا (اختصاصی هر هورمون) تشکیل شده است. fsh گاوی در تکنولوژی تولید مثل، مانند سوپراوولاسیون حیوانات مزرعه ای و درمان سندرم پلی سیستیک تخمدان استفاده می شود. همچنین این هورمون برا...
