Molecular subgrouping of medulloblastoma (MB) has produced four subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4. While patients with WNT tumors have the best prognosis, patients with SHH tumors have a more variable prognosis concurrent with metastatic disease. This subset of SHH patients have elevated levels of the neurogenic regulator, RE1 Silencing Transcription factor (REST). To understand the role of REST in MB, we utilized a novel transgenic mouse model wherein REST expression can be conditionally elevated during postnatal development in the cells of origin of SHH MB, cerebellar granule neural progenitors (GNPs). While these mice did …
