Based on gene profiling, four MB subgroups have been identified, i.e., Wnt or Sonic Hedgehog (Shh) types, and subgroup 3 or 4. The Shh-type MB has been shown to arise from the cerebellar precursors of granule neurons (GCPs), where a hyperactivation of the Shh pathway leads to their neoplastic transformation. We have previously shown that the gene Tis21 (PC3/Btg2) inhibits the proliferation and promotes the differentiation and migration of GCPs. Moreover, the overexpression or the deletion of Tis21 in Patched1 heterozygous mice, a model of spontaneous Shh-type MB, highly reduces or increases, respectively, the frequency of MB. Here we tested whether Tis21 can inhibit MB allografts. Athymic nude mice were subcutaneously grafted with MB cells explanted from Patched1 heterozygous mice. MB allografts were then injected with adeno-associated viruses either carrying Tis21 (AAV-Tis21) or empty (AAV-CBA). We observed that the treatment with AAV-Tis21 significantly inhibited the growth of tumor nodules, as judged by their volume, and reduced the number of proliferating tumor cells (labeled with Ki67 or BrdU), relative to AAV-CBA-treated control mice. In parallel, AAV-Tis21 increased significantly tumor cells labeled with early and late neural differentiation markers. Overall the results suggest that Tis21-gene therapy slows down MB tumor growth through inhibition of proliferation and enhancement of neural differentiation. These results validate Tis21 as a relevant target for MB therapy.
