Neuro 24 studies of tumor biology can growth our understanding of regular development. Learning that Ptc is a medulloblastoma tumor suppressor led at once to the identification of the Ptc ligand Sonic hedgehog as a powerful mitogen for cerebellar granule cell precursors. Much stays to be found out about the genetic occasions that cause mind tumors and how every event regulates cell cycle development apoptosis and differentiation.
