Heme Oxygenase and Atherosclerosis [PDF]

Arteriosclerosis, Thrombosis, and Vascular Biology, 2005
Overproduction of reactive oxygen species under pathophysiological conditions, including dyslipidemia, hypertension, diabetes, and smoking, is integral in the development of cardiovascular diseases (CVD). The reactive oxygen species released from all types of vascular cells regulate various signaling pathways that mediate not only vascular inflammation

Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

European Journal of Inorganic Chemistry, EarlyView.
The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Oxygenase Coordination Is Required for Morphological Transition and the Host–Fungus Interaction of Aspergillus flavus

Molecular Plant-Microbe Interactions, 2009
Oxylipins, a class of oxygenase-derived unsaturated fatty acids, are important signal molecules in many biological systems. Recent characterization of an Aspergillus flavus lipoxygenase gene, lox, revealed its importance in maintaining a density ...

Crystalline l-Lysine Oxygenase

Journal of Biological Chemistry, 1966
Abstract l-Lysine oxygenase has been purified about 100-fold from cells of Pseudomonas fluorescens and crystallized. The crystalline enzyme contains 2 moles of flavin adenine dinucleotide per mole of enzyme, the molecular weight of which has been estimated to be 191,000.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Carotinoid-Oxygenase in Chlorella

Zeitschrift für Naturforschung B, 1958
In Chlorella wurde ein bisher unbekanntes labiles Oxygenasesystem gefunden, das im Dunkeln mit großer Geschwindigkeit Sauerstoff auf Carotinoide überträgt und das durch Licht gehemmt wird. Vgl. dazu O. WARBURG, G. KRIPPAHL und W. SCHRÖDER, Wirkungsspektrum eines Photosynthese-Ferments, diese Z. 10 b, 631 [1955].

Protozoan ALKBH8 oxygenases display both DNA repair and tRNA modification activities.

PLoS ONE, 2014
The ALKBH family of Fe(II) and 2-oxoglutarate dependent oxygenases comprises enzymes that display sequence homology to AlkB from E. coli, a DNA repair enzyme that uses an oxidative mechanism to dealkylate methyl and etheno adducts on the nucleobases ...

Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

Ibrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

Occupational Exposure to Factory‐Derived Particulate Matter 2.5 Induces Cutaneous Toxicity in Workers and HaCaT Keratinocytes Through Oxidative Stress and Inflammation

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study aimed to evaluate the toxicological effects of occupational exposure to factory‐derived particulate matter (PM2.5) on human skin, emphasizing its role as a potential target organ of environmental toxicants. An epidemiological survey comparing factory and nonfactory workers was conducted by assessing their skin elasticity and color ...
