A synthetic peptide corresponding to the third cytoplasmic loop (residues 533 to 555) of the testicular follicle-stimulating hormone receptor affects signal transduction in rat testis membranes and in intact cultured rat Sertoli cells

Autor: Leo E. Reichert, Leng N, Patricia Grasso

Publikováno v: Molecular and Cellular Endocrinology. 110:35-41

Involvement of the third cytoplasmic (3i) loop (residues 533 to 555) of the rat testicular FSH receptor in the mechanism of FSH signal transduction was examined using light membranes prepared from immature rat testes, monolayer cultures of rat Sertol

Transforming growth factor-beta 1 modulates calcium metabolism in Sertoli cells

Autor: Tomás A. Santa-Coloma, M B Sporn, Leo E. Reichert, Patricia Grasso

Publikováno v: Endocrinology. 132:1745-1749

The mechanism of signal transduction by transforming growth factor-beta 1 (TGF-beta 1) is largely unknown. In this study, TGF-beta 1 was able to stimulate 45Ca2+ uptake in cultured rat Sertoli cells. In contrast to the rapid stimulation of 45Ca2+ upt

Effects of Mono(2-Ethylhexyl) Phthalate, a Testicular Toxicant, on Follicle-Stimulating Hormone Binding to Membranes from Cultured Rat Sertoli Cells1

Publikováno v: Biology of Reproduction. 48:454-459

The widely used plasticizer di(2-ethylhexyl) phthalate (DEHP) is a male reproductive toxicant. Its toxicity has been shown to be due primarily to the action of its metabolite mono(2-ethylhexyl) phthalate (MEHP) on Sertoli cells. We have previously sh
