Abstract:Medulloblastoma is the most common malignant brain tumor of childhood. Therapeutic approaches to medulloblastoma have led to significant improvements, but are achieved at a high cost to quality of life. Aberrant upregulation of the hedgehog (Hh) pathway drives cerebellar tumorigenesis in ∼30% of medulloblastoma patients. Hh pathway inhibitors such as the SMO antagonist Vismodegib are currently being tested in Hh-activated medulloblastoma and the preliminary results are encouraging. However, resistance to SMO i… Show more
