Representative Western blots showing levels of autophagy‐associated proteins; Parkin and LC3BII examined in mitochondrial fractions. Representative Western blots showing phosphorylated‐JNK, total JNK, p62, and LC3BII total levels 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 and β‐actin were used as a loading control for mitochondrial fraction (top panels) and total fraction (lower panels), respectively. Protein levels were quantified and presented as fold change of hSOD‐1 WT.
