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.

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.

Serum diamine oxidase (DAO) activity as a diagnostic test for histamine intolerance [PDF]

Clinical and Translational Allergy, 2011
Background Histamine intolerance (HIT) is characterized by an imbalance between histamine intake and the capacity for histamine degradation. The main enzyme for metabolizing ingested histamine is diamine oxidase (DAO). Determining DAO activity in serum may be useful in diagnosing HIT.

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 ...

Advances in the Clinical Application of Histamine and Diamine Oxidase (DAO) Activity: A Review

Catalysts, 2022
The serum level of diamine oxidase (DAO) reflects the integrity and maturation of the small intestinal mucosa. This measure is important in diagnosing various diseases, including chronic urticaria tachyphylaxis, multiple organ dysfunction syndrome, preterm abortion, and migraine.

Measurement of diamine oxidase (DAO) during low-histamine or ordinary diet in patients with histamine intolerance. [PDF]

Eur J Clin Nutr
Abstract Background/Objectives Quantification of diamine oxidase (DAO) concentrations in serum has been proposed as an adjunctive diagnostic modality for the evaluation of histamine intolerance (HIT).

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

Biologia 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.

[Studies on diamine oxidase (DAO) activity in seminal plasma]. [PDF]

Hinyokika kiyo. Acta urologica Japonica, 1989
Diamine oxidase (DAO: EC 1.4.3.6) activity was measured for seminal plasma of patients complaining of infertility to investigate whether measurement of DAO activity in seminal plasma is a significant laboratory examination or not for evaluation of male infertility.

Evaluation of the Safety and Tolerability of Three Single Ascending Doses of Diamine Oxidase (DAO) in Healthy Volunteers: A Randomized Clinical Trial

International Journal of Translational Medicine
Background/Objectives: Diamine oxidase (DAO) enzyme metabolizes dietary histamine in the gastrointestinal tract. DAO deficiency can lead to histamine intolerance (HIT), manifesting as migraines, gastrointestinal disturbances, and allergic reactions.
