Role of phosphatidylinositol-3-kinase in insulin receptor signaling: studies with inhibitor, LY294002.

abstract：:The in vitro effects of various steroid and thyroid hormones on synthesis of rat atrial natriuretic peptide (rANP) were studied using new-born rat atrial myocytes in culture. Dexamethasone, testosterone and triiodothyronine markedly stimulated both synthesis and secretion of immunoreactive (IR)-rANP with the same peak...
