The key-enzyme for the metabolism of diamines in man is diamine oxidase (DAO). Its highest activities are in the intestinal mucosa, localized in the cytoplasm of the mature enterocytes of the small and large bowel. If the gut is affected by inflammation in Crohn's disease macroscopical changes are observed.

How reliable are DAO supplements? — A comparison of over-the-counter Diamine oxidase products
2023Abstract Diamine oxidase (DAO) supplements have gained increasing attention in recent years due to their potential to support DAO deficiency, histamine intolerance and related symptoms. However, choosing a reliable and trustworthy DAO supplement can be a challenging task for patients and Healthcare practitioners.

Some problems with the diamine oxidase (DAO) assay using putrescine as substrate in rat liver
Agents and Actions, 1993Determination of diamine oxidase (DAO) activity in rat liver preparations by measuring the formation of radioactive delta 1-pyrroline from 14C-putrescine is complicated by the complexity of competing metabolic pathways. This can lead to complete masking of the DAO activity present when rat liver homogenates are used as the enzyme source.

Changes in serum and intestinal diamine oxidase (DAO) activity after proximal enterectomy in rats
Digestive Diseases and Sciences, 1989To determine whether serum and mucosal DAO activity reflects quantitative changes in the small bowel mucosal mass, we have chosen an experimental model of mucosal hyperplasia which is known to occur in the rat after enterectomy. A 50% proximal enterectomy or a single transection was performed in 20 growing rats weighing 145-160 g.

AbstractThe postheparin DAO increase in blood plasma has been shown to depend on intact intestines in rat and rabbit. Our findings indicate, however, that sources of mobilizable DAO may be found also outside the small intestine in these species. In the rat, after partial portal stricture for a week.

In the intestinal mucosa, diamine oxidase (DAO) seems to be involved in a feed-back regulation mechanism for the termination of proliferation. Therefore, we studied the DAO activity in large bowel tumors and in the non-affected mucosa of these patients in comparison with patients having a normal large mucosa. The DAO activity in the tumor tissue itself

Homoveratrylamine inhibited hog kidney diamine oxidase “in vitro”, developed a catatonia-like state in mice and increased vascular permeability of rats. The last two effects were conspicuously enhanced if homoveratrylamine was given together with histamine.

The aim of this study was to assess the effect inhibiting diamine oxidase (DAO) activity on intestinal adaptation after 80% proximal small bowel resection in the rat. Aminoguanidine (AG), a DAO inhibitor, was administered subcutaneously (25 mg kg-1 day-1) to rats for 11 days after small bowel transection (n = 6) or resection (n = 6).
