1*Denotes p < 0.05, **denotes p < 0.01, ***denotes p < 0.001, and ****denotes p < 0.0001 comparing changes in neuronal survival at each concentration compared to C9(+/+) parental by two-way ANOVA analysis of variance followed by Dunnett’s test. IC50s were calculated using a four-parameter logistical regression model.
