(A) Time course of changes in accelerating rotarod performance
at different ages. Note that MitoPark mice treated with PT320 have
values almost equal to those of WT animals, whereas untreated MitoPark
mice are significantly impaired at later ages (red dashed circle).
Two-way analysis of variance (ANOVA) followed by a Bonferroni post
hoc test for multiple comparisons. WT male compared to MitoPark (MP)
male: #, p < 0.05; ##, p < 0.01; and ###, p <
0.001. MP male compared to PT320-treated MP male: *, p < 0.05; **, p < 0.01. (B) Accelerating rotarod
performance in 20, 22, and 24 week old MP mice. Unpaired t-test: *, p < 0.05, and **, p < 0.01.
