Effect of thyrotropin on the sensitivity of thyroid nuclear deoxyribonucleic acid to digestion by micrococcal nuclease.

abstract：:Stimulators of bone resorption, such as PTH, 1,25-dihydroxycholecalciferol [1,25-(OH)2D3], or prostaglandin E2 (PGE2), do not cause calcium release from cultured calvaria of the genetically determined osteopetrotic microphthalmic (mi/ mi) mouse, due to a defect in the function of osteoclasts.

abstract：:Angiotensin II (AngII) stimulates aldosterone biosynthesis in the zona glomerulosa of the adrenal cortex. AngII also triggers the MAPK pathways (ERK1/2 and p38). Because ERK1/2 phosphorylation is a transient process, phosphatases could play a crucial role in the acute steroidogenic response. Here we show that the dual...
