Levels of Parkin and LC3BII autophagy measures were determined in mitochondrial fractions by immunoblotting in hSOD1‐WT‐ and hSOD1‐G93A‐expressing NSC‐34 differentiated cells as in A, cultured in the presence or absence of P110 (1 μM/24 h); VDAC was used as a loading control. Protein levels were quantified and presented as fold change of MOCK (empty vector).
