E2F and GATA-1 are required for the Sertoli cell-specific promoter activity of the follicle-stimulating hormone receptor gene
Transcription factor testis gonadotropin
2008/12/29
The follicle-stimulating hormone receptor (FSHR) gene is expressed in Sertoli cells in males and in granulosa cells in females. Cis-acting sequences and associated binding factors responsible for ...
Thyroid hormone receptors in neonatal, prepubertal, and adult rat testis
Thyroid hormone receptors adult rat testis
2008/12/26
Thyroid hormone (TH) is involved in the differentiation and development of rat testis, whereas its role in adult testis function is still undefined. The aim of our work has been to further analyze the...
Marked species specificity of guinea pig luteinizing hormone：validation of a bioassay
species specificity guinea pig validation of a bioassay
2008/12/26
The Guinea pig is a potentially interesting alternative small animal model for the study of the neuroendocrine regulation of reproduction. However, appropriate gonadotropin assays are not widely ava...
Androgen-Dependent transcriptional regulation of the prostate-specific antigen gene by thyroid hormone 3,5,3'-L-triiodothyronine
the prostate-specific antigen gene thyroid hormone 3,5,3'-L-triiodothyronine
2008/12/26
Prostate-specific antigen (PSA) is the most useful biomarker for human prostate cancer and may play a role in prostate tumor biology. Androgens, via their receptors, are the major positive regulators ...
The Effect of Growth Hormone on Craniofacial Growth and Dental Maturation in Turner Syndrome
Craniofacial growth Growth hormone Turner syndrome Dental development
2008/12/26
Serial cephalometric and panoramic radiographs from a mixed longitudinal group of 28 subjects with Turner syndrome (TS), age 4.4–19.0 years, were evaluated for annualized growth increments of the ...
Differential actions of gonadotropin-releasing hormone and human chorionic gonadotropin on interstitial fluid volume and immunoglobulin G concentrations in adult rat testis
gonadotropin-releasing hormone human chorionic gonadotropin interstitial fluid volume immunoglobulin G concentrations adult rat testis
2008/12/25
Gonadotropin-releasing hormone (GnRH) agonists regulate testicular interstitial fluid (tIF) volume, most probably via specific receptors on Leydig cells. The aim of this study was to confirm the int...
Involvement of inhibin in the regulation of follicle-stimulating hormone secretion in the young adult male Shiba goat
Involvement of inhibin follicle-stimulating hormone secretion young adult male Shiba goat
2008/12/25
The roles of inhibin and testosterone in the regulation of gonadotropin secretion were investigated in young adult male Shiba goats (8-12 months of age). Plasma levels of inhibin but not testoster...
Effects of triptorelin, a gonadotropin-releasing hormone agonist, on the human prostatic cell lines PC3 and LNCaP
triptorelin a gonadotropin-releasing hormone agonist human prostatic cell lines PC3 LNCaP
2008/12/25
Some analogues of gonadotropin-releasing hormone (GnRH) influence the in vitro proliferation of cultured human cells by complex interactions that are only partially understood. This study explored t...
Effects of luteinizing hormone, follicle-stimulating hormone, and epidermal growth factor on expression and kinase activity of cyclin-dependent kinase 5 in Leydig TM3 and Sertoli TM4 cell lines
luteinizing hormone follicle-stimulating hormone growth factor kinase activity cyclin-dependent kinase 5
2008/12/25
We examined the effects of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and epidermal growth factor (EGF) on the expression and kinase activity of cyclin-dependent kinase 5 (Cdk5)...
