Diamine oxidase (DAO) activity increase in sera of tumor patients: An unreliable marker

The International Journal of Biological Markers, 1989
Circulating diamine oxidase (DAO) (EC 1.4.3.6) activity was determined in the sera of patients with different malignant tumors. The increase in this activity only partially reflected tumor activity so it is presumably unreliable as a diagnostic marker ...

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Inhibition of chickpea seedling copper amine oxidases by tetraethylenepentamine [PDF]

Copper amine oxidases are important enzymes, which contribute to the regulation of monoand polyamine levels. Each monomer contains one Cu(II) ion and 2,4,5-trihydroxyphenylalanine (TPQ) as cofactors.

Nitrate Enhances Gastric Mucosa Defense and Repair Process in Ethanol‐Induced Gastric Ulcer Rats via the Notch–Tff2 Pathway

MedComm, Volume 7, Issue 2, February 2026.
Nitrate protects the three major barriers of the gastric mucosa, alleviating bleeding and inflammation of ethanol‐induced gastric ulcer in rats, and promotes migration of gastric epithelial cells, accelerating the restoration of the ulcerated epithelium, which is strongly related to TFF2, a gastric mucosal protective factor negatively regulated by the ...

Inoculation response of mycorrhizas on morphology and physiological behaviour of trifoliate orange (Poncirus trifoliata) roots under salt stress

The Indian Journal of Agricultural Sciences, 2016
Citrus is highly sensitive to salt stress, and little efforts have been successful microbiologically to mitigate such abiotic stress. In this background, trifoliate orange [Poncirus trifoliata (L.) Raf.] seedlings were inoculated with Diversispora ...

HPLC–UV assay for the evaluation of inhibitors of plasma amine oxidase using crude bovine plasma

Journal of Enzyme Inhibition and Medicinal Chemistry, 2019
Recently, we have described a method for evaluation of plasma amine oxidase (PAO) inhibitors, which monitors the formation of 6-(5-phenyl-2H-tetrazol-2-yl)hexanal from the corresponding amine substrate by HPLC with UV-detection using purified bovine PAO.

Development and Characterization of a Diamine Oxidase-Based Histamine Biosensor [PDF]

, 2006
Histamine levels have been suggested as a rapid fish spoilage indicator. Therefore, histamine biosensors based on immobilization of diamine oxidase (DAO) in photocurable poly (2-hydroxyethyl methacrylate) (photoHEMA) film was developed.

Development of a Capacitance-Based Biosensor for the Determination of Histamine Concentration [PDF]

, 2009
Histamine level has been suggested as a rapid fish spoilage indicator. Besides that, a biosensor device with low cost, simple and portable is an advantage for fish freshness monitoring.
