Figure 7.
Rotarod behavior of single and double knockout mice. The rotarod performance of three separate cohorts of mice is shown in (A), (B) and (C). 2-way ANOVA with genotype and trial as factors showed a significant effect of trial as all genotypes learned the task and a significant increase in the latency to fall for double knockout mice compared to wild-type mice at all ages (p<0.0001). Asterisks indicate trials with significant differences compared to wild-type mice according to post-hoc analysis. DJ-1−/− mice were significantly different from wild-type mice at age 6 months but not at age 16 months. Parkin−/− mice were not significantly different from wild-type mice at any age.
