In situ hybridization was used to examine cellular differentiation during rat adrenal regeneration, defining zona glomerulosa [cytochrome P-450 aldosterone synthase ( P-450aldo) mRNA positive], zona fasciculata [cytochrome P-450 11β-hydroxylase ( P-45011β) mRNA positive], or zona intermedia [negative for both but 3β-hydroxysteroid dehydrogenase (3β-HSD) mRNA positive]. After unilateral adrenal ...
The aim of the present work was to determine the effects of liver growth factor (LGF) on the regeneration process of rat testes after chemical castration induced by ethane dimethanesulfonate (EDS) by analyzing some of the most relevant proteins involved in cholesterol metabolism, such as hormone sensitive lipase (HSL), 3β-hydroxysteroid dehydrogenase (3β-HSD), scavenger receptor SR-BI, and othe...
Few data have suggested how norepinephrine (NE) and acetylcholine (Ach) regulate the development of Leydig cells in mice at prepuberty, except for data indicating endocrine effects. The present study aims to elucidate the roles of NE and Ach on the differentiation and proliferation of Leydig cells. Firstly, the expression of adrenergic receptors and muscarinic acetylcholine receptors in Leydig ...
The enzyme 3beta-hydroxysteroid dehydrogenase (3beta-HSD) is a key enzyme in the biosynthesis of steroid hormones. To date, this laboratory has isolated and characterized five distinct 3beta-HSD complementary DNAs (cDNAs) in the mouse (3beta-HSD I through V). These different forms are expressed in a tissue- and developmentally-specific manner and fall into two functionally distinct enzymes. 3be...
A biopsy procedure was developed to enable repeated sampling of a single equine corpus luteum (CL) over the course of an estrous cycle. The tissue collected was utilized in characterizing mRNA abundance for genes involved in luteal formation, function, and regression in the cyclic mare. Serial biopsies of CL in cyclic mares (2.7 to 27.5 mg per biopsy) were collected using an ultrasound-guided t...
