The cytochemical localization of adenylate cyclase activity in mucous and serous cells of the salivary gland.
The present study was undertaken to localize adenylate cyclase activity in salivary glands by cytochemical means. For the study, serous parotid glands and mixed sublingual glands of the rat were used. Pieces of the fixed glands were incubated with adenosine triphosphate (ATP) or adenylyl-imidodiphosphate (AMP-PNP) as substrate: inorganic pyrophosphate or PNP liberated upon the action of adenyla...
متن کاملBiochemical characterization and cytochemical localization of a catecholamine-sensitive adenylate cyclase in isolated capillary endothelium.
Capillaries were isolated from epididymal fat, and a catecholamine-sensitive adenylate cyclase found in these capillaries was characterized. The effect of various hormones on the accumulation of adenosine 3':5'-cyclic monophosphate in capillary endothelial cells was determined and the cyclase was found to exhibit mixed alpha and beta characteristics. Cyclase was cytochemically localized in thes...
متن کاملCytochemical Localization of Guanylate and Adenylate Cyclase in Photoreceptor Cells of the Fly
Electron Microscopy, Guanylate Cyclase, Adenylate Cyclase, Photoreceptor, Fly In photoreceptor cells of invertebrates light triggers an enzyme cascade in which the phosphoinositide pathway is crucially involved. Likewise, there is growing evidence of an impor tant role of cyclic nucleotides, too. To localize these enzymes able to catalyze the formation of cGMP and cAMP, the spatial distributio...
متن کاملE VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
متن کاملLocalization of adenylate cyclase during development of Dictyostelium discoideum.
Cyclic AMP is known to function as the chemotactic signal during aggregation of single-celled amoebae of the cellular slime mold Dictyostelium discoideum. Evidence from several laboratories has accumulated suggesting that cAMP also acts as a regulatory molecule during Dictyostelium multicellular differentiation. We have used ultramicrotechniques and a sensitive radioimmunoassay in the localizat...
