Activation and Phosphorylation of the 'Dense-Vesicle' High-Affinity Cyclic AMP Phosphodiesterase by Cyclic AMP-Dependent Protein Kinase
Biochem. J. (1989) 260, 27-36 (Printed in Great Britain) 27 Activation and phosphorylation of the 'dense-vesicle' high-affinity cyclic AMP phosphodiesterase by cyclic AMP-dependent protein kinase Elaine KILGOUR, Neil G. ANDERSON and Miles D. HOUSLAY Molecular Pharmacology Group, Department of Biochemistry, University of Glasgow, Glasgow G12 8QQ, Scotland, U.K. Incubation of a hepatocyte particulate fraction with ATP and the isolated catalytic unit of cyclic AMP- dependent protein kinase (A-kinase) selectively activated the high-affinity 'dense-vesicle' cyclic AMP phosphodiesterase. Such activation only occurred if the membranes had been pre-treated with Mg2". Mg2" pre-treatment appeared to function by stimulating endogenous phosphatases and did not affect phosphodiesterase activity. Using the antiserum DV4, which specifically immunoprecipitated the 51 and 57 kDa components of the 'dense-vesicle' phosphodiesterase from a detergent-solubilized membrane extract, we isolated a 32P-labelled phosphoprotein from 32P-labelled hepatocytes. MgCl2 treatment of such labelled membranes removed 32P from the immunoprecipitated protein. Incubation of the Mg2+-pre-treated membranes with [32P]ATP and A-kinase led to the time-dependent incorporation of label into the 'dense- vesicle' phosphodiesterase, as detected by specific immunoprecipitation with the antiserum DV4. The time- dependences of phosphodiesterase activation and incorporation of label were similar. It is suggested (i) that phosphorylation of the 'dense-vesicle' phosphodiesterase by A-kinase leads to its activation, and that such a process accounts for the ability of glucagon and other hormones, which increase intracellular cyclic AMP concentrations, to activate this enzyme, and (ii) that an as yet unidentified kinase can phosphorylate this enzyme without causing any significant change in enzyme activity but which prevents activation and phosphorylation of the phosphodiesterase by A-kinase. -

Isidori,4 Silvia Migliaccio,1 Noemi Poerio,5 Maurizio Fraziano,5 Andrea Lenzi,4 and Clara Crescioli1,6 Abstract—T helper 1 (Th1) type cytokines and chemokines are bioactive mediators in inflammation underling several diseases and co-morbid conditions, such as cardiovascular and metabolic disorders. Th1 chemokine CXCL10 participates in heart damage initiation/progression; cardioprotection has been recently associated with sildenafil, a type 5 phosphodiesterase inhibitor. We aimed to evaluate the effect of sildenafil on CXCL10 in inflammatory conditions associated with diabetic cardiomyopathy. We analyzed: CXCL10 gene and protein in human cardiac, endothelial, and immune cells challenged by pro-inflammatory stimuli with and without sildenafil; serum CXCL10 in diabetic subjects at cardiomy- opathy onset, before and after 3 months of treatment with sildenafil vs. placebo. Sildenafil significantly −7 decreased CXCL10 protein secretion (IC50 =2.6×10 ) and gene expression in human cardiomyocytes and significantly decreased circulating CXCL10 in subjects with chemokine basal level ≥ 930 pg/ml, the cut-off value as assessed by ROC analysis. In conclusion, sildenafil could be a pharmacologic tool to control CXCL10-associated inflammation in diabetic cardiomyopathy. -
Effects of Phosphodiesterase Inhibitors on Human Lung Mast Cell and Basophil Function

Weston, Nicola Anderson & 1Peter T. Peachell Department of Medicine & Pharmacology, University of Sheeld, Royal Hallamshire Hospital (Floor L), Glossop Road, Sheeld S10 2JF 1 The non-hydrolysable cyclic AMP analogue, dibutyryl (Bu2)-cyclic AMP, inhibited the stimulated release of histamine from both basophils and human lung mast cells (HLMC) in a dose-dependent manner. The concentrations required to inhibit histamine release by 50% (IC50) were 0.8 and 0.7 mM in basophils and HLMC, respectively. The cyclic GMP analogue, Bu2-cyclic GMP, was ineective as an inhibitor of histamine release in basophils and HLMC. 2 The non-selective phosphodiesterase (PDE) inhibitors, theophylline and isobutyl-methylxanthine (IBMX) inhibited the IgE-mediated release of histamine from both human basophils and HLMC in a dose-dependent fashion. IBMX and theophylline were more potent inhibitors in basophils than HLMC. IC50 values for the inhibition of histamine release were, 0.05 and 0.2 mM for IBMX and theophylline, respectively, in basophils and 0.25 and 1.2 mM for IBMX and theophylline in HLMC. 3 The PDE 4 inhibitor, rolipram, attenuated the release of both histamine and the generation of sulphopeptidoleukotrienes (sLT) from activated basophils at sub-micromolar concentrations but was ineective at inhibiting the release of histamine and the generation of both sLT and prostaglandin D2 (PGD2) in HLMC. Additional PDE 4 inhibitors, denbufylline, Ro 20-1724, RP 73401 and nitraquazone, were all found to be eective inhibitors of mediator release in basophils but were ineective in HLMC unless high concentrations (1 mM) were employed. -

Mykles Deborah Garrity Shane Kanatous Santiago Di-Pietro Copyright by Nada Mukhtar Rifai 2019 All Rights Reserved ABSTRACT CHARACTERIZATION OF CYCLIC NUCLEOTIDE PHOSPHODIESTERASES IN THE TRANSCRIPTOME OF THE CRUSTACEAN MOLTING GLAND Molting in crustaceans is a complex physiological process that has to occur in order for the animal to grow. The old exoskeleton must be discarded and a new one to be formed from the inside out. Molting is coordinated and regulated mainly by two hormones; steroid hormones named ecdysteroids, which are synthesized and secreted from a pair of Y- organs (YOs) that are located in the cephalothorax and a neuropeptide hormone, the molt inhibiting hormone (MIH), which is secreted from the X-organ/sinus gland complex located in the eyestalks. Molting is induced when MIH is decreased in the blood (hemolymph) which in turn stimulates the YOs to produce and secrete ecdysteroids (molting hormones). There are four distinctive physiological states that the YO can be in throughout the molt cycle; the transition of the YO from the “basal” to the “activated” state happens when the animal enters premolt. During mid-premolt, the YO transitions to the “committed” state, in which the YO becomes insensitive to MIH. In this state, the circulating hemolymph contains high levels of ecdysteroids, which increase to a peak before the actual molt (ecdysis) happens. -

Memory Enhancers for Alzheimer's Dementia
pharmaceuticals Review Memory Enhancers for Alzheimer’s Dementia: Focus on cGMP Ernesto Fedele 1,2,* and Roberta Ricciarelli 2,3,* 1 Department of Pharmacy, Section of Pharmacology and Toxicology, University of Genoa, 16148 Genova, Italy 2 IRCCS Ospedale Policlinico San Martino, 16132 Genova, Italy 3 Department of Experimental Medicine, Section of General Pathology, University of Genoa, 16132 Genova, Italy * Correspondence: [email protected] (E.F.); [email protected] (R.R.) Abstract: Cyclic guanosine-30,50-monophosphate, better known as cyclic-GMP or cGMP, is a classical second messenger involved in a variety of intracellular pathways ultimately controlling different physiological functions. The family of guanylyl cyclases that includes soluble and particulate en- zymes, each of which comprises several isoforms with different mechanisms of activation, synthesizes cGMP. cGMP signaling is mainly executed by the activation of protein kinase G and cyclic nucleotide gated channels, whereas it is terminated by its hydrolysis to GMP operated by both specific and dual-substrate phosphodiesterases. In the central nervous system, cGMP has attracted the attention of neuroscientists especially for its key role in the synaptic plasticity phenomenon of long-term potentiation that is instrumental to memory formation and consolidation, thus setting off a “gold rush” for new drugs that could be effective for the treatment of cognitive deficits. In this article, we summarize the state of the art on the neurochemistry of the cGMP system and then review the pre-clinical and clinical evidence on the use of cGMP enhancers in Alzheimer’s disease (AD) therapy. Although preclinical data demonstrates the beneficial effects of cGMP on cognitive deficits in AD animal models, the results of the clinical studies carried out to date are not conclusive.
