TranscriptomicsOncogenic mutation in Smoothened causes severe cerebellar developmental defects and medulloblastoma in mice
Deregulated developmental processes in the cerebellum cause medulloblastoma, the most common malignant tumor of the central nervous system. About 20-30% of cases are caused by mutations increasing the activity of the Sonic hedgehog (Shh) pathway, a critical mitogen in cerebellar development. The pro...

TranscriptomicsFundamental differences in promoter CpG island DNA hypermethylation between human cancer and genetically engineered mouse models of cancer [Methylation profiling by array]
Genetic and epigenetic alterations are essential for the initiation and progression of human cancer. We previously reported that primary human medulloblastomas showed extensive cancer-specific CpG island DNA hypermethylation in critical developmental pathways. To determine whether genetically engine...
