Representative Western blots showing levels of cytochrome c, BAX, and Bcl‐2 were examined in mitochondrial fractions by immunoblotting in hSOD1‐WT‐ and hSOD1‐G93A‐expressing NSC‐34 differentiated cells under serum starvation in the presence or absence of P110 (1 μM/24 h); VDAC. Protein levels were quantified and presented as fold change of hSOD‐1 WT.
