Prevalence of Diamine Oxidase Enzyme (DAO) Deficiency in Subjects with Insomnia-Related Symptoms

Journal of Clinical Medicine
Background/Objectives: To assess the prevalence of diamine oxidase (DAO) enzyme deficiency caused by single nucleotide polymorphisms (SNPs) of the AOC1 gene in a sample of patients with symptoms of insomnia. Methods: A total of 167 adult patients (> 18 years of age) with symptoms of insomnia attended in a specialized institute for healthy ...

Toward food-grade production of the Glutamicibacter halophytocola diamine oxidase using Komagataella phaffii [PDF]

AMB Express
The diamine oxidase from Glutamicibacter halophytocola (DAO-GH) was recombinantly produced in K. phaffii using the constitutive glyceraldehyde-3-phosphate dehydrogenase promoter for methanol-free production. Firstly, K.

Mapping of the binding sites of human diamine oxidase (DAO) monoclonal antibodies. [PDF]

Inflamm Res, 2018
Recently we characterized five mouse monoclonal antibodies that allow the specific and sensitive detection of human diamine oxidase (DAO). To understand differences in binding characteristics and recognition of enzyme variants, we mapped the antibody binding sites.Fragments of human DAO were expressed as glutathione-S-transferase fusion proteins that ...

Impact of technological factors on diamine oxidase (DAO) activity in porcine kidney extracts as active ingredient for the dietary management of histamine intolerance

Applied Food Research
Histamine intolerance is associated with impaired histamine metabolism due to diamine-oxidase (DAO) enzyme deficiency at intestinal level. The recommended strategy to alleviate the symptomatology is a low-histamine diet supplemented with DAO.

Intestinal expression of diamine oxidase (DAO) and the relationship between blood DAO activity and haptoglobin concentration in diarrheal calves. [PDF]

J Vet Med Sci
The objectives of this study were (1) to confirm the expression of diamine oxidase (DAO) in the intestines of healthy calves immune-histologically and to clarify whether the expression of DAO in the intestines of calves with diarrhea differs from that of healthy animals, and (2) to clarify the relationship between DAO and intestinal inflammation using ...

Cumulative effect of AOC1 gene variants on symptoms and pathological conditions in adult women with fibromyalgia: a pilot study

Frontiers in Genetics, 2023
Introduction: The amine oxidase copper-containing 1 (AOC1) gene encodes for the diamine oxidase (DAO) enzyme. DAO is an enzyme that catabolizes some molecules, including histamine, and is the degradative enzyme in the polyamine catabolic pathway that is ...

Degradation of histamine in tuna soup by diamine oxidase (DAO) [PDF]

WIT Transactions on Ecology and the Environment, 2011
Histamine is a biogenic amine, which can cause food poisoning when present at high concentrations (>500 ppm). In situations where the formation of histamine in food cannot be prevented through traditional methods such as refrigeration, diamine oxidase (DAO) enzyme may be a suitable method to reduce histamine concentration to safe levels.

Role of diamine oxidase in the pathogenesis of chronic urticaria

Медицинская иммунология, 2022
Chronic urticaria is a polyetiological disease proceeding by various immunological and non-immunological (pseudo-allergic) mechanisms. Food intolerance is a distinct type of pseudo-allergies, manifesting, e.g., with histamine intolerance syndrome, caused

Semicarbazide diminishes the signs of bleomycin-induced pulmonary fibrosis in rats [PDF]

The Ukrainian Biochemical Journal, 2021
The pathogenesis of pulmonary fibrosis (PF) is accompanied by extracellular matrix (ECM) deposition, oxidative stress, and inflammation progression, as well as hyperactivation of amine oxidases (AOs), which contribute to disease manifestation.
