The differential effects of the indazole-carboxylic acid derivative, tolnidamine, on Sertoli cell protein secretion
Indazole-carboxylic acids tolnidamine antispermatogenic agents Sertoli cell
2009/2/23
The indazole-carboxylic acid derivative tolnidamine (TOL) has marked antispermatogenic activity in rats. Previous morphological and biochemical studies indicate that Sertoli cells are one of the tar...

TM4 Sertoli cell line rat Sertoli cell-enriched cultures
2009/2/23
The effects of synthetic salmon calcitonin on primary Sertoli cell-enriched cultures and on an established cell line (TM4 cells, derived from immature mouse Sertoli cells) were studied. Synthetic ...
Estradiol and plasminogen activator secretion by cultured rat Sertoli cells in response to melanocyte-stimulating hormones
Estradiol and plasminogen activator secretion cultured rat Sertoli cells melanocyte-stimulating hormones
2009/2/23
Pro-opiomelanocortin-derived peptides, alpha-MSH and beta-endorphin, are synthesized and secreted by Leydig cells, and are believed to have paracrine effects on Sertoli cells in the testis. Peptid...
Incorporation of gossypol and formation of its protein conjugates in mouse transformed Sertoli（TM4）cells
protein conjugates mouse transformed Sertoli（TM4）cells
2009/2/23
Mitochondria of both mouse transformed Sertoli (TM4) cells and primary-cultured rat and mouse Sertoli cells were shown to be preferentially affected by gossypol (Tanphaichitr et al, 1984). To invest...
Polyamine profiles in rat testis, germ cells and Sertoli cells during testicular maturation
Polyamine profiles rat testis germ cells Sertoli cells
2009/2/23
Polyamine cellular concentrations (putrescine, spermidine and spermine) in the rat testis and testicular cell types were determined by fluorescence spectroscopy of their dansyl derivatives. A met...
Transferrin secretion in response to different modes of FSH stimulation and cycloheximide in superfused Sertoli cell cultures
Transferrin secretion FSH stimulation cycloheximide superfused Sertoli cell cultures
2009/2/23
The influence of different modes of FSH stimulation and cycloheximide on transferrin secretion by rat Sertoli cells was investigated using a superfusion culture system. Sertoli cells from 18-day-old...

germ cells vectorial secretion androgen binding protein transferrin immature rat Sertoli cells
2009/2/23
The influence of germ cells (greater than 85% pachytene spermatocytes) on vectorial secretion of androgen binding protein (ABP) and transferrin by immature rat Sertoli cells was investigated using t...
Inhibition of ornithine decarboxylase activity by follicle stimulating hormone in primary culture of rat Sertoli cells
ornithine decarboxylase follicle stimulating
2009/2/23
The effect of follicle stimulating hormone on the activity of ornithine decarboxylase (ODC) was determined in primary culture of rat Sertoli cells. Three different FSH preparations (NIH oFSH-S-15, S...
Tonic inhibition of adenylate cyclase in cultured hamster Sertoli cells
cAMP hamster Sertoli cell adenylate cyclase culture pertussis toxin
2009/2/23
Sertoli cells cultured from immature hamsters respond to FSH with a dose-related increase in cAMP accumulation. Pertussis toxin acts synergistically with FSH to stimulate cAMP accumulation. This eff...
Cholinergic inhibition of cAMP accumulation in Sertoli cells cultured from immature hamsters
