TranscriptomicsThe miR-17/92 Polycistron Is Up-regulated in Sonic Hedgehog-Driven Medulloblastomas and Induced by N-myc in Sonic Hedgehogâ??Treated Cerebellar Neural Precursors
Medulloblastoma is the most common malignant pediatric brain tumor, and mechanisms underlying its development are poorly understood. We identified recurrent amplification of the miR-17/92 polycistron proto-oncogene in 6% of pediatric medulloblastomas by high-resolution single-nucleotide polymorphism...

TranscriptomicsHigh-resolution copy number analysis of medulloblastoma
We used high-resolution SNP genotyping to identify regions of genomic gain and loss in the genome of 212 medulloblastomas, a malignant pediatric brain tumor. Focal amplifications of fifteen known oncogenes and focal deletions of twenty known tumor suppressor genes (TSG) were revealed, most not prev...

TranscriptomicsSubgroup specific somatic copy number aberrations in the medulloblastoma genome [mRNA]
Affymetrix Human Gene 1.1 ST Array profiling of 285 primary medulloblastoma samples. Total RNA was extracted from primary medulloblastoma samples and hybridized to Affymetrix Human Gene 1.1 ST Arrays (24-Array Plates) according to the manufacturer's instructions.
