ZIC1 and cerebellar neoplasm: We generated cerebellar tumors using myristylated AKT (AKT) under the control of the zic:Gal4 promoter as described in Mayrhofer et al. (2017) (Figure 5D) and we observed that neither ALT activity nor tert gene expression was changed compared to control cerebellar tissue (Figures 5E,F).
