Figure 3: ARPE-19 cells had signifi cantly increased caspase-9 activity after 24 h treatment with 2-EP at concentrations of 40 μM, 30 μM, and 20 μM, compared with untreated cultures (P<0.001). The cultures treated with 2-EP at 10 μM concentration and untreated culture showed minimal caspase-9 activities (P>0.05). 2-EP, 2-ethylpyridine; ***P<0.001
