Levels of α-synuclein protein expression in the striatum of wild type and parkin transgenic mice.

<p>Western blot showing α-synuclein protein in the striatum of young (A) and old (C) mice after saline or MPTP treatment. (B, D) Quantification of relative α-synuclein protein expression. Data presented are the means±SE. # p<0.05, significant differences between wild type and transgenic mice; n = 4−6 per group.
