Webtissues. Diamine oxidase activity seems to predominate in the intestine, whereas, N-methyltransferase activity predominates in the brain (Holcslaw et al 1985; Schayer and Reilley 1973). However, there is evidence that inhibition of one pathway may switch the degradation to the other, even within the same organ. WebThe Caco-2 cells have been used as a model system to study the pathways of diamine oxidase secretion by the intestinal epithelium. When grown in Transwell filter chamber devices, the polarized cell monolayers released the enzyme preferentially into the basal chamber.
