Stimulation by appropriate agents of protein and polypeptide secretion in various glands is accompanied by an increased turnover of P32 in phospholipides; the effect is greatest in phosphoinositide and phosphatidic acid (l-5). To establish whether the phospholipide effect is confined to protein and polypeptide secretion or whether it may also be concerned with the secretion of smaller molecules...

The activity of phenylethanolamine N-methyltransferase, the enzyme that catalyzes the N-methylation of noradrenaline to form adrenaline, falls following hypophysectomy. Enzyme activity can be restored by injections of adrenocorticotropic hormone (ACTH) or of dexamethasone, a potent synthetic glucocorticoid.
