Prevalence of Genetic Diamine Oxidase (DAO) Deficiency in Female Patients with Fibromyalgia in Spain [PDF]
Biomedicines, 2023 Diamine oxidase (DAO) is an enzyme that metabolizes intestinal histamine. Single nucleotide polymorphisms (SNPs) of the Amine Oxidase Copper Containing 1 (AOC1) gene can lead to low enzymatic activity or functionality in histamine metabolism.

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 [PDF]
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

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

Multivariate statistical optimization of the ultrasonic-assisted extraction of diamine oxidase (DAO) from pea sprout [PDF]
Ultrasonics SonochemistryPea sprouts can provide a plant-based alternative to the commonly used pork kidney as a source of diamine oxidase (DAO), an enzyme used as a dietary supplement to prevent symptoms of histamine intolerance.

Plasma diamine oxidase activity in asthmatic children
Allergology International, 1996 Histamine plays an important role in the development of asthmatic symptoms. Diamine oxidase (DAO histaminase), which inactivates histamine, is located in the intestine and kidney and is released into plasma.

Histamine intolerance caused by Diamine Oxidase (DAO) deficiency – case report
Journal of Pre-Clinical and Clinical Research, 2022 Histamine is a biogenic amine, which occurs naturally in the human body. Histamine can be metabolised with Diamine Oxidase (DAO) Enzyme. It is estimated that in 1% of people, as a result of an imbalance between the supply and degradation of histamine, a ...

Testosterone as Diamine Oxidase Activity Regulator [PDF]
BioDiscovery, 2017 Diamine oxidase (DAO) is a key enzyme of the metabolism of polyamines. Its activity was assayed in homogenate of male immature rat liver and kidney. The androgens are important regulators of polyamines’ metabolism.
