Fig. 7. Deletion of GAPDH isoform 2 and 3 prevents H2O2-induced apoptosis. (A) Comparison of the survival of wild-type,
tdh2 and
tdh3 cells upon H2O2 treatment, *P
0.03 versus wild type, t-test, n=3. (B) Epifluorescence and phase-contrast micrographs of untreated and H2O2-treated (1.5 mM) wild-type,
tdh2 and
tdh3 cells, stained with dihydrorhodamine 123 (DHR123) as an indicator of high intracellular ROS accumulation. Bar, 5 µm.
