Heme oxygenase-2 gene deletion attenuates the neurotoxic effect of hemin. Cultures were treated with indicated concentrations of hemin for 14 h. Injury was assessed by A) LDH activity in the medium, which is scaled to that in sister cultures treated with 300 μM NMDA for 40 h (= 100), which releases essentially all neuronal LDH; B) fluorescence intensity of cultures stained with propidium iodide, again scaled to that in sister cultures treated with NMDA. *P < 0.05, ***P < 0.001 v. knockout cultures treated with same concentration of hemin, Bonferroni multiple comparisons test.
