Sigma-2 Ligands generate Superoxide Radical in the Mitochondria. Mitochondrial Superoxide detection in (a) Panc02, (b) AsPC-1, (c) KP02, (d) BxPC3, after 2 h treatment with 50 μM sigma-2 ligands alone or in combination with the lipid antioxidant α-tocopherol (1 mM). Values are the means of n ≥ 3 independent experiments in triplicates with SEM, p < 0.0001
