Dose-dependent reduction of somatic repeat expansion index by silencing Msh3 using di-siRNA in HdhQ111/+ mice. (A) Representative fragment analysis traces showing somatic CAG repeat expansions in the striatum of HdhQ111/+ at 3 months of age, and untreated, treated ICV with vehicle, 3 nmol di-siRNA, and 10 nmol di-siRNA at 6 months of age. (B) Quantification of the somatic expansion index in the striatum (STR), cortex (CTX), cerebellum (CEB) and liver (LIV). Error bars represent mean ± SD; n = 10. One-way ANOVA with Tukey’s post hoc analysis, *p < 0.05, **p < 0.01, ***p < 0.0001 and ****p < 0.0001.
