Mitogen‐Activated Protein Kinase and Intracellular Polyamine Signaling Is Involved in TRPV1 Activation–Induced Cardiac Hypertrophy

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe transient receptor potential vanilloid type 1 (TRPV1) is expressed in the cardiovascular system, and increased TRPV1 expression has been associated with cardiac hypertrophy.

Sensing and adaptation to low pH mediated by inducible amino acid decarboxylases in Salmonella. [PDF]

open access: yesPLoS ONE, 2011
During the course of infection, Salmonella enterica serovar Typhimurium must successively survive the harsh acid stress of the stomach and multiply into a mild acidic compartment within macrophages.

mRNA dynamics and alternative conformations adopted under low and high arginine concentrations control polyamine biosynthesis in Salmonella. [PDF]

open access: yesPLoS Genetics, 2019
Putrescine belongs to the large group of polyamines, an essential class of metabolites that exists throughout all kingdoms of life. The Salmonella speF gene encodes an inducible ornithine decarboxylase that produces putrescine from ornithine.

Anticancer efficacy of phenolics based structurally related compounds and their radical scavenging action [PDF]

open access: yes, 2011
Cancer, one of the leading causes of death worldwide, is an abnormal cell proliferation that fails to respond to the normal signals. In an effort to eradicate the growing menace of cancer, a clear understanding of fundamental biology and molecular ...

Immunocytochemical Detection of Ornithine Decarboxylase [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 1999
Ornithine decarboxylase (ODC), a regulatory enzyme of polyamine biosynthesis, is involved in cell growth and differentiation. Lack of information about the exact cellular and subcellular localization of ODC is one of the main obstacles to precise interpretation of the biological roles of the ODC/polyamine system.

Species of Staphylococcus and Bacillus isolated from traditional sausages as producers of biogenic amines.

open access: yesFrontiers in Microbiology, 2012
Histidine, lysine, ornithine and tyrosine decarboxylase activities were tested in 38 strains of Staphylococcus (15 of Staph. equorum, 11 of Staph. epidermidis, 7 of Staph. saprophyticus, and 5 of Staph.

Effect of cyclosporine on hepatic cytosolic estrogen and androgen receptor levels before and after partial hepatectomy [PDF]

open access: yes, 1990
Estrogen and androgen receptors within the liver have been reported to modulate the hepatic regenerative response to partial hepatectomy. Moreover, cyclosporine has several untoward effects that might occur as a consequence of alterations in sex hormone ...

Uric Acid Deteriorates Load-Free Cell Shortening of Cultured Adult Rat Ventricular Cardiomyocytes via Stimulation of Arginine Turnover

open access: yesBiology, 2022
Hyperuricemia is a risk factor for heart disease. Cardiomyocytes produce uric acid via xanthine oxidase. The enzymatic reaction leads to oxidative stress in uric-acid-producing cells.

Ornithine Decarboxylase mRNA is Stabilized in an mTORC1-dependent Manner in Ras-transformed Cells [PDF]

open access: yes, 2012
Upon Ras activation, ODC (ornithine decarboxylase) is markedly induced, and numerous studies suggest that ODC expression is controlled by Ras effector pathways. ODC is therefore a potential target in the treatment and prevention of Ras-driven tumours. In

Glutamate, Ornithine, Arginine, Proline, and Polyamine Metabolic Interactions: The Pathway Is Regulated at the Post-Transcriptional Level [PDF]

open access: yes, 2016
The metabolism of glutamate into ornithine, arginine, proline, and polyamines is a major network of nitrogen-metabolizing pathways in plants, which also produces intermediates like nitric oxide, and γ-aminobutyric acid (GABA) that play critical roles in ...
