“…There have been several reports on the role of H202, oxygen radicals and oxidative stress in polyamine-induced toxicity in the presence of bovine serum amine oxidase. Inhibition of lymphocyte proliferation was independent of exogenously added catalase [24], whereas spermidine toxicity in CHO cells was decreased by the presence of catalase [46], as was the clastogenic effect of spermine in mouse lymphoma cells [47]. Studies using exogenous catalase are difficult to interpret, as the enzyme is a known constituent of serum, and its activity will vary between sera and different batches of the same serum.…”

“…3‐aminopropanal, 3‐AP, is highly toxic at rather low concentrations to a variety of cells, including neurons, glial cells, endothelial cells, fibroblasts, and a range of transformed mammalian cell types (6, 32, 33). The exact mechanisms behind the pronounced cytotoxicity of this small amino aldehyde, however, are not yet generally realized.…”

“…3-Aminopropanal was previously implicated as cytotoxic and cytostatic to primary endothelial cells, fibroblasts, and other transformed mammalian cell lines in culture [54][55][56][57][58]. Toverify that 3-aminopropanal is generated by oxidative cleavage of spermine and spermidine by PAO, we used stereotactic microinjection methods to administer spermine, spermidine, and putrescine into the cerebral cortex of rats and then measured the volume of tissue death that developed at the injection site.Spermine and spermidine, but not putrescine, mediated significant cortical brain cell death [18].…”
