Diamine oxidase (DAO) supplement reduces headache in episodic migraine patients with DAO deficiency: A randomized double-blind trial [PDF]
Histamine intolerance is a disorder in the homeostasis of histamine due to a reduced intestinal degradation of this amine, mainly caused by a deficiency in the enzyme diamine oxidase (DAO). Among histamine related symptoms, headache is one of the most recorded. Current clinical strategies for the treatment of the symptomatology related to this disorder

Histamine intolerance is associated with impaired histamine metabolism caused by a deficiency of the enzyme diamine oxidase (DAO). A recommended strategy to alleviate symptoms is a low-histamine diet supplemented with exogenous DAO. Recent studies suggest plant-based DAO from legume sprouts could be a viable active ingredient for supplements.

Prediction of the amount and rate of histamine degradation by diamine oxidase (DAO)
Food Chemistry, 2012Histamine is a biogenic amine that forms in a variety of foods and can cause food poisoning at high concentrations (>500 ppm). In situations where the formation of histamine in food cannot be prevented through refrigeration, diamine oxidase (DAO) enzyme may be used to degrade histamine to safe levels.

Diamine oxidase (DAO) and female sex hormones
Agents and Actions, 1986DAO activity in tissues of female guinea pigs was determined after the administration of estradiol or progesterone. Estradiol pretreatment elicited significant fall in DAO activity in the liver and specific increase in the uterus. The effect of progesterone was much less pronounced.

A Spectrophotometric Method for Determination of Diamine Oxidase (DAO) Activity
Acta Physiologica Scandinavica, 1959Abstract.If diamine oxidase is allowed to act upon the diamine putrescine, a cyclic compound, δl‐pyrroline, will be formed, which in turn reacts with o‐aminobenzaldehyde to form a yellow compound. These reactions have been taken as a starting point for a photometric method for determination of diamine oxidase.

Equations of Substrate-inhibition Kinetics Applied to Pig Kidney Diamine Oxidase (DAO, E.C. 1.4.3.6)
Pig kidney diamine oxidase (DAO) and other semicarbazide-sensitive amine oxidases (SSAO) show clear substrate-inhibition kinetics and a reaction-scheme mechanism based on two substrate binding sites. We evaluated several reaction scheme mechanisms with a non-linear regression program (NCSS), estimating R2, the constants of the equations and their ...

On the Elimination of Transfused Heparin‐Induced Diamine Oxidase (DAO) Activity in Rabbits
Acta Physiologica Scandinavica, 1973AbstractLymph or blood plasma, rich in diamine oxidase (DAO; EC 1.4.3.6.) activity was obtained from donor rabbits, after i.v. injection of heparin. The lymph or, after heparin neutralization, the blood serum was injected into recipient rabbits, and the elimination of the transfused DAO activity was studied.

Effect of Intestinal Diamine Oxidase (DAO) Depletion by Heparin on Mucosal Polyamine Metabolism
Digestion, 2009The aim of this study was to examine the relative importance of the enzymes ornithine decarboxylase (ODC) and diamine oxidase (DAO) in intestinal polyamine metabolism in normal rats. To study this we measured jejunal and ileal DAO and ODC activities and polyamine levels 2 h after injecting, in non-fasting male Wistar rats, either normal saline ...

A FURTHER INVESTIGATION OF THE RELATIONSHIP BETWEEN SERUM DIAMINE OXIDASE (DAO) AND GESTATIONAL AGE
BJOG: An International Journal of Obstetrics & Gynaecology, 1976SummaryA standard error of one to two weeks must be accepted if the duration of pregnancy is calculated from serum diamine oxidase (DAO) concentrations. After the 16th week of pregnancy, the enzyme concentration is too variable to be used for calculations of gestational age.
