Dao (diaminoxidase) purification from natural sources and enzyme-enriched food production

Applied Food Research
Histamine intolerance, affecting approximately 1–3 % of the population, is linked to elevated histamine levels that can mimic allergic reactions. Diamine oxidase (DAO) plays a key role in histamine degradation.

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

Depression Aggravates Immune‐Mediated Hepatitis Through NLRP3 Overactivation Induced by Intestinal Microbiota

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Depression is common in AIH patients and is associated with an elevated cirrhosis risk. AIH patients with depression, mice colonized with MDD microbiota, and ConA‐treated mice subjected to CUMS exhibit intestinal barrier dysfunction and hepatic NLRP3 inflammasome overactivation.

Microglial VRK2 Regulates Astrocytic GABA Synthesis and Tonic Inhibition in the Thalamus

Glia, Volume 74, Issue 1, January 2026.
In Vrk2‐deficient mice, tonic GABA inhibition is reduced in the mediodorsal thalamus due to impaired astrocytic GABA synthesis. Microglial VRK2 regulates this process via TNF‐α signaling, revealing a glial–glial mechanism of thalamic inhibition.

Purification and characterization of diamine oxidase from clover leaves

, 1987
Diamine oxidase (DAO, EC 1.4.3.6) was purified 135-fold from leaves of subterranean clover (Trifolium subterraneum L. cv Seaton Park) and three isoenzymes were identified. The native enzyme has an M of ca 150 000 and comprises two subunits both having an

Dietary Berberine Improves Liver and Intestinal Health for Hybrid Yellow Catfish (Pelteobagrus fulvidraco ♀ × Pelteobagrus vachelli ♂) Suffered Dual Stress From Soybean Meal‐Induced Enteritis and Lipopolysaccharide

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
In order to investigate the effect of dietary berberine (BBR) on lipopolysaccharide (LPS) stimulation in hybrid yellow catfish with soybean meal‐induced enteritis (SBMIE), two diets were formulated: a control diet containing 33.75% soybean meal (SBM) and an experimental diet with 33.75% SBM supplemented with 75 mg/kg BBR.

Influence of Seed Disinfection Treatments on the Germination Rate and Histamine-Degrading Activity of Legume Sprouts

Foods
Edible legume sprouts have been proposed as a promising plant-based source of the enzyme diamine oxidase (DAO), which plays a key role in degrading histamine at an intestinal level and preventing the development of histamine intolerance symptoms. However,

Application of sucrose modulates the expressions of genes involved in proline and polyamine metabolism in maize seedlings exposed to drought

Biologia Plantarum, 2019
Sucrose, proline, and polyamines are compatible solutes accumulating in plant tissues and increasing cellular osmolarity under environmental stresses. These compatible solutes and hydrogen peroxide can function as signaling molecules in plants. There has
