In isolated rat liver cells in which lipid peroxidation is stimulated by CCl4, a strong inhibition of S-adenosylmethionine decarboxylase (SAMD) activity occurs. Some purified aldehydes, which are produced during lipid peroxidation, are able to inhibit SAMD activity in Yoshida hepatoma cells. The most active aldehyde is hydroxypentenal (HPE). It inhibits by 50% SAMD activity at 0.5 mM concentration in entire hepatoma cells, or in hepatoma cell sap, and at 0.1 mM concentration in partially purified hepatoma cell sap fractions.
