These data suggest that more reactive free radicals generated from the hydrazine are responsible for protein damage, that damaged protein (hemoglobin) is degraded via proteolysis, and that an ATP-independent process primarily participates in the degradation of abnormal proteins in the red cell.

The addition of a chemical inducer, such as dimethylsulfoxide (DMSO), to cultures of mouse Friend erythroleukemic cells results in the induction of a number of late erythroid events, including the accumulation of globin mRNA, the inducation of hemoglobin synthesis, the appearance of erythrocyte membrane antigens (EMA), and the cessation of cell division.

Optimal conditions for the visualization of these granules by incubation in alkaline DAB were obtained when the peroxidase activity of hemoglobin was reduced by addition of low concentrations of potassium cyanide.

Because of the autoxidation of the unstable hemoglobin chains and subsequent release of globin free heme and iron, significant amounts of superoxide (O2-) and, more importantly, hydrogen peroxide (H2O2) are generated intracellularly.

From the measurement of catalase activity in erythrocytes treated with 3-amino-1,2,4-triazole and rates of hydrogen peroxide removal by the erythrocytes, it is deduced that rate constants related to the hemoglobin content (k/g Hb) for hydrogen peroxide removal by catalase in normal and acatalasemic erythrocytes are 42.0 +/- 6.0 and 8.0 +/- 3.0, respectively.

The relative importance in human red blood cells of the plasma membrane as a site of redox activation of anthracyclines as compared to hemoglobin was evaluated by assaying the H2O2 produced upon exposure to daunomycin.

Hydrolysis of hemoglobin in the digestive vesicles of these cells results in the release of large amounts of heme, a pro-oxidant compound, whose iron atom, together with H (2) O (2), may participate in the Fenton reaction and lead to the production of hydroxyl radicals.
