Mitochondrial health using mitochondrial membrane potential (TMRM) and mitochondria‐specific ROS indicator (MitoSOX), nitric oxide levels (Griess reagent), and cell death (using LDH assay) in hSOD1‐WT‐ and hSOD1‐G93A‐expressing NSC‐34 differentiated cells cultured in the presence or absence of P110 (1 μM for 24 h). Results are presented as percent or fold of MOCK (empty vector); n = 3 performed in quintuplet; probability by one‐way ANOVA (with Tukey's post hoc test). Scale bar: 50 μm.
