Expressions of caspase 9 and caspase 3, two markers of apoptosis, in the heart tissue of R6/2 HD mice under oral B307 treatment and of their WT.
Notes: (A) IHC staining illustrates that expressions of caspase 9 and caspase 3 (shown in brown) were remarkable in comparison to their WT but were reduced under oral B307 treatment. Scale bars: 25 μm. (B, C) Western blotting analysis shows the following: (a) Cardiac expression levels of caspase 9 and caspase 3 in R6/2 HD mice under sham and oral B307 treatments, and of their WT. (b) Quantified cardiac caspase 9 and caspase 3 levels in R6/2 HD mice were significantly enhanced in comparison to their WT but were significantly weaker under oral B307 treatment. There were six mice per each group. Values are mean ± SEM (**P<0.01, *P<0.05, two-way ANOVA followed by a Student–Newman–Keuls multiple comparisons posttest).
Abbreviations: WT, wild-type littermate controls; HD, Huntington’s disease; IHC, immunohistochemical; SEM, standard error of the mean; ANOVA, analysis of variance.
