Cyclooxygenase-1 and cyclooxygenase-2 in the mouse ductus arteriosus: individual activity and functional coupling with nitric oxide synthase

Autor: Flavio Coceani, Silvia Barogi, Cameron Ackerley, Barbara Baragatti, Francesca Brizzi, Leslie R. Ballou

Publikováno v: British Journal of Pharmacology. 139:1505-1515

1 Prenatal patency of the ductus arteriosus is maintained by prostaglandin (PG) E2, conceivably in concert with nitric oxide (NO). Local PGE2 formation is sustained by cyclooxygenase-1 (COX1) and cyclooxygenase-2 (COX2), a possible exception being th

Cytochrome c oxidase and mitochondrial F1F0-ATPase (ATP synthase) activities in platelets and brain from patients with Alzheimer's disease

Publikováno v: Neurobiology of Aging. 23:371-376

Evidence suggests that mitochondrial dysfunction is prominent in Alzheimer’s disease (AD). A failure of one or more of the mitochondrial electron transport chain enzymes or of F1F0-ATPase (ATP synthase) could compromise brain energy stores, generat

Effect of the oxidative stress induced by adriamycin on rat hepatocyte bioenergetics during ageing

Autor: Giorgio Lenaz, Alessandra Baracca, Silvia Barogi, M. Cavazzoni, Giovanna Parenti Castelli

Publikováno v: Mechanisms of Ageing and Development. 113:1-21

We have investigated the effect of ageing and of adriamycin treatment on the bioenergetics of isolated rat hepatocytes. Ageing per se, whilst being associated with a striking increase of hydrogen peroxide in the cells, induces only minor changes on m

Conformational Changes of the Mitochondrial F1-ATPase ∊-Subunit Induced by Nucleotide Binding as Observed by Phosphorescence Spectroscopy

Autor: Alessandra Baracca, Silvia Barogi, Giancarlo Solaini, Edi Gabellieri

Publikováno v: Scopus-Elsevier

Changes in conformation of the epsilon-subunit of the bovine heart mitochondrial F1-ATPase complex as a result of nucleotide binding have been demonstrated from the phosphorescence emission of tryptophan. The triplet state lifetime shows that whereas

Gene expression in ductus arteriosus and aorta: comparison of birth and oxygen effects

Autor: Chiara Chiellini, Nicholas D. Socci, Flavio Coceani, Margherita Maffei, Mario Costa, Emanuela Grasso, Barbara Baragatti, Debora Angeloni, Silvia Barogi

Ductus arteriosus (DA) closure is initiated by oxygen rise postnatally and progresses in two, functional-to-permanent, stages. Here, using GeneChip Arrays in rats (normoxic and hyperoxic fetus, normoxic newborn), we examined whether oxygen alone dupl

Cyclooxygenase isoenzymes and patency of ductus arteriosus

Autor: Francesca Brizzi, Cameron Ackerley, Silvia Barogi, Lois Kelsey, Eric Seidlitz, Barbara Baragatti, Leslie R. Ballou, Flavio Coceani

Publikováno v: Prostaglandins, leukotrienes, and essential fatty acids. 72(2)

Prenatal patency of the ductus arteriosus is maintained mainly by prostaglandin (PG) E(2). Accordingly, the vessel is endowed in its muscular component with a complete, cyclooxygenase (COX) and PGE synthase (PGES), system for the synthesis of the com

Cyclooxygenase (COX) Function in the Ductus Arteriosus: Another Look

Autor: Francesca Brizzi, Flavio Coceani, Cameron Ackerley, Barbara Baragatti, Silvia Barogi

Publikováno v: Advances in Experimental Medicine and Biology ISBN: 9781461348313

It is well accepted that patency of the ductus arteriosus in the fetus is an active process being sustained primarily by prostaglandin E2 (PGE2) but conceivably involving other agents, nitric oxide (NO) in particular [1]. Previous investigations, usi

Fluorescence resonance energy transfer between coumarin-derived mitochondrial F(1)-ATPase gamma subunit and pyrenylmaleimide-labelled fragments of IF(1) and c subunit

We introduced a reporting group into a critical position of the mitochondrial F(1)-ATPase in order to gain structural information about enzyme-ligand complexes. Incubation of 7-diethylamino-3-(4'-maleimidylphenyl)-4-methylcoumarin (CPM) with bovine h
