Comparing hydrazine-derived reactive groups as inhibitors of quinone-dependent amine oxidases

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2017
Lysyl oxidase has emerged as an important enzyme in cancer metastasis. Its activity has been reported to become upregulated in several types of cancer, and blocking its activity has been shown to limit the metastatic potential of various cancers.

Nutrients regulate diamine oxidase release from intestinal mucosa

open access: yes, 1998
Diamine oxidase is continuously released from the intestinal mucosa and carried to the circulation by the lymphatics. The effect of nutrients on this release was examined. Rats were prepared with duodenal and intestinal lymph cannulas.

Stimulation of antioxidative enzymes and polyamines during stripe rust disease of wheat

open access: yesBiologia Plantarum, 2010
Content of polyamines and activities of antioxidative enzymes in response to stripe rust disease caused by Puccinia striiformis have been studied in two wheat (Triticum aestivum L.) cultivars PBW 343 (resistant) and HD 2329 (susceptible).

Probiotics and intestinal permeability in adults with metabolic dysfunction‐associated steatohepatitis: A secondary analysis of a randomized clinical trial

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Metabolic dysfunction‐associated steatohepatitis (MASH) is associated with altered intestinal permeability, allowing microbial products to translocate to the liver via the enterohepatic circulation and contributes to disease progression. The aim of our study was to evaluate the association between probiotic supplementation and serum

Release of intestinal diamine oxidase by histamine in rats

open access: yes, 1983
Diamine oxidase activity was measured in the intestinal mucosa, lymph, and in the serum of rats, to determine whether histamine, a substrate of diamine oxidase, liberates this enzyme from its mucosal storage site(s).

Spatial and temporal dynamics of peroxidase and amine oxidase activity is linked to polyamines and lignin in wheat grains

open access: yesBiologia Plantarum, 2010
The regulation of contents and activities of peroxidase (POX), diamine oxidase (DAO) and polyamine oxidase (PAO) were determined in relation to polyamines and lignin content in wheat (Triticum aestivum L.) grains.

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

open access: yesWorld 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
