Pediatric Brain Tumors
Medulloblastoma is the most common malignant brain tumor of childhood. It arises from cerebellar granule cell precursors, in some cases through mutations that lead to excess signaling of the sonic hedgehog pathway. In a multi-institutional collaborative study, we showed that one type of medulloblastoma (desmoplastic histology) overexpresses genes that are downstream of hedgehog and that another type (classic histology) is notable for overexpression of a small group of genes including the transcription factor, neuroD3/neurogenin (Pomeroy, 2001). Based on these studies, we are generating new mouse models of medulloblastoma and testing candidate drugs that interfere with the aberrant signaling pathways. For the latter goal, we lead a national consortium for pre-clinical analysis of new compounds. So far, we have demonstrated efficacy of two drug classes, retinoids and cyclopamine derivatives (Hallahan, 2003; Berman, 2002). Both effectively induce apoptosis in medulloblastoma cells derived from patient surgical samples and in established medulloblastoma cell cultures. We elucidated the mechanism by which retinoids induce apoptosis, providing a basis for understanding why some cells are sensitive to this agent and others are resistant. Based on these data, we are developing a national Phase III clinical trial through the Children’s Oncology Group to assess the efficacy of retinoids in children with high risk medulloblastoma/primitive neuroectodermal tumor.
Dr. Olson is the author of “Clinical Pharmacology Made Ridiculously Simple,” a textbook geared toward medical students making the transition from classroom pharmacology to clinical pharmacology. The principles of pharmacology and the relationships that we have developed in research divisions of pharmaceutical companies accelerate translation of our basic research into clinical practice.
