Caspase 3 and cytochrome C in dopaminergic neurons upon DA-toxins application.

(A) Quantification of mesencephalic neurons positive for TH and caspase 3 staining. (B) Representative pictures of TH neurons, negative (left panel) and positive (right panel) for cleaved caspase 3. (C) Quantification of mesencephalic neurons positive for TH and cytochrome C staining. (D) Representative pictures of TH neurons, negative (left panel) and positive (right panel) for cytochrome C. Value of 1 is equivalent to 8 +/- 0,4 neurons (A) or to 5 +/- 0,4 neurons (C). All values were expressed as mean +/- SEM; n = 6/group; *, p<0,05 with One-way ANOVA followed by Dunnett’s test.
