We found for the first time that the positive expression rate of VASH2 was closely associated with SHH-type pediatric medulloblastoma and that VASH2 was involved in the invasion, migration, cell cycle, and apoptotic capacity of SHH medulloblastoma cell lines DAOY by affecting downstream indicators of the TGF-β pathway. Here, TGFB1 is linked to medulloblastoma.
