Decrease of glutathione and fatty acids during iron-induced lipid peroxidation in Ehrlich ascites tumor cells

In order to investigate a possible relationship between the intensity of lipid peroxidation (LP) in tumor cells and their proliferative activity various methods to quantify LP are desirable. In this study the decrease in the contents of fatty acids and glutathione was measured by established methods inEhrlich ascites tumor (EAT) cellsin vitro, in which LP was stimulated by the addition of ferrous iron, either as free ion or as histidinate chelate.
