Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

Animal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

Inhibiting Copper Amine Oxidase Using L-Aminoguanidine Induces Cultivar and Age-Dependent Alterations of Polyamine Catabolism in Tomato Seedlings

Agriculture, 2022
Many effects of polyamines (PAs) are well known in plant developmental processes; however, the significance of their catabolism is not well understood. Copper amine oxidase (CuAO) is involved in the degradation of diamine putrescine (Put).

Standardization of a colorimetric technique for determination of enzymatic activity of diamine oxidase (DAO) and its application in patients with clinical diagnosis of histamine intolerance

World Allergy Organization Journal, 2020
Background: Diamine Oxidase (DAO) has an essential role for degradation of exogenous histamine in the intestine; thus, histamine intolerance (HI) mainly has been correlated to a low concentration and/or activity of this enzyme. The objective of the study

Downregulation of Polyamine and Diamine Oxidases in Silicon-Treated Cucumber

Plants, 2021
Silicon (Si) is a ubiquitous element in soil with well-known beneficial effects under certain conditions, in several plant species, if supplied in available form for uptake. It may alleviate damage in various stress situations and may also promote growth

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

Histidine is the axial ligand to cytochrome alpha 3 in cytochrome c oxidase [PDF]

, 1981
The nitric oxide-bound complexes of reduced yeast cytochrome c oxidase incorporated with [1,3-15N2]histidine have been investigated by EPR spectroscopy. The results of this study have allowed the unambiguous identification of histidine as the endogenous ...
