The membrane location and mechanism of inositol 1,3,4,5-tetrakisphosphate (InsP4)-regulated Ca2+ uptake in cardiac membrane vesicles was investigated. In canine and rat membranes separated by sucrose density gradient centrifugation, InsP4-regulated C

Muscarinic receptor regulation of guanine nucleotide turnover on Gi/Go proteins in ventricular sarcolemma was investigated. In the absence of a muscarinic receptor (MR) agonist, GTP bound to background sites with a Kapp value of 60 nM and a Bmax of 5

We investigated the signaling pathways modulating histamine- and prostaglandin F2 alpha (PGF2 alpha)-induced contractions of human chorionic vasculature. Neomycin, a phospholipase C (PLC) inhibitor, attenuated PGF2 alpha and histamine contractile res

The effects of inositol phosphates on Ca2+ uptake in cardiac junctional sarcoplasmic reticulum (JSR) vesicles was investigated. Inositol 1,3,4,5-tetrakisphosphate (IP4) selectively increased Ca2+ uptake 2.8 fold over basal levels whereas 1,3,4-IP3, 1

The effect of chronic ventricular sympathectomy on sarcolemmal muscarinic receptor (MR) and beta-adrenoceptor densities and coupling of these receptors to adenylyl cyclase was examined. Microsomal membranes were isolated from right and left ventricle

The mechanism by which NAD stimulates cardiac adenylate cyclase was investigated. In highly purified canine cardiac sarcolemma, NAD stimulated adenylate cyclase activity in the presence of agents which activate Gs (i.e. 5 mM AlF4-, 10 microM GTP gamm

Incubation of canine heart slices with 32P-inorganic phosphate in physiological medium resulted in the incorporation of 32P into a number of cardiac phospholipids. Carbachol, a non-hydrolyzable acetylcholine analogue, selectively increased 32P-incorp

The properties of muscarinic agonist stimulated phosphoinositide turnover in canine atrial slices were investigated. In slices prelabeled with 32Pi, carbachol stimulated a 20-30% decrease of 32P-labeled phosphatidylinositol 4'-phosphate (PIP) and pho

Human erythrocyte membranes obtained by freeze-thawing of ghosts prepared in the absence or presence of EDTA, by washing with a 12 mosm medium at pH 7.7 or a 2 mosm medium at pH 6.5 contain both high and low Ca affinity (Mg + Ca)-ATPase activities. I
