Diclofenac-Induced Apoptosis in the Neuroblastoma Cell Line SH-SY5Y: Possible Involvement of the Mitochondrial Superoxide Dismutase
Figure 3
Effect of diclofenac on SOD2 protein levels. (a) Dose dependence. SH-SY5Y cells were incubated with the indicated concentrations of diclofenac for 24 hours. The SOD2 protein level was evaluated by immunoblotting; as a loading control, the same filter was probed with anti-GAPDH antibody. (b) Time dependence. SH-SY5Y cells were incubated with vehicle alone or 150 M diclofenac at the indicated times and treated as indicated in (a). β-tubulin was used as house-keeping control. (c, d) Densitometry evaluation of three independent experiments carried out as in (a) and (b), respectively; # compared to untreated cells.
