Reduction of G6PDH abundance protects against the motor neuron toxicity of PR50 and GA50. Panel A. A three-way comparison of number of motor neurons expressing LacZ + scr, PR50 + scr miRNA and PR50 + G6PDH miRNA. Statistically significant group differences were seen by ANOVA and post hoc test reveal that PR50 + scr miRNA is significant different from LacZ + scr and from PR50 + G6PDH miRNA. Results from ≥4 experiments, ∗, p < 0.05. A three-way comparison of number of motor neurons expressing LacZ + scr, GA50 + scr miRNA and GA50 + G6PDH miRNA.
