GAH reduces PC12 cell death as analyzed using ethidium homodimer 1. PC12 cells were incubated with ethidium homodimer 1 after treatment with 5000 μM of hydrogen peroxide for 4 h. Images in the upper panel are ethidium homodimer 1 staining (red) and the lower panel DAPI stained nuclei (blue) of PC12 cells. The number of dead cells per 100 cells is shown. GAH more effectively prevented cell death relative to no peptides and carnosine. All data are shown as mean ± SE of three independent experiments (p < 0.01). DAPI = 4′,6-diamidino-2-phenylindole
