To identify molecular subtypes of medulloblastoma we have profiled a series of 62 medulloblastoma tumors. Unsupervised hierarchical cluster analysis of these data identified 5 distinct molecular subtypes. Manuscript submitted. Title: Identification of medulloblastoma subtypes with distinct genetic p...

Copy number analysis of 21 paediatric low-grade astrocytomas identified a discrete copy number gain of 1.9Mb in chromosome band 7q34. The gain was present in 12/14 cerebellar pilocytic astrocytomas. Subsequent analysis of tumour cDNA indentified a novel gene fusion between KIAA1549 and BRAF in these...

Mouse models of medulloblastoma are compared to human subgroups through microarray expression and other measures This study contrasts mouse medullablastomas from a range of mouse genetic models. For Shh-type medulloblastoma [dka001-005, 009, 033 and 034] and [dka050-057], spontaneous medulloblastom...

A series of mouse models designed to mimic pediatric medulloblastoma types in humans were tested by microarray and compared to published human medulloblastoma data Myc-type tumors [dka201-203] were generated by orthotopic injection of Myc-infected cerebellar cells from Cdkn2c-/-, Trp53-/-, Atoh1-GFP...

Mutations in the PTEN, TP53 and RB1 pathways are obligate events in the pathogenesis of human glioblastomas, the highest grade of astrocytoma. To investigate synergy between these tumor suppressors in mice, we induced various combinations of compound deletions conditionally in astrocytes and neural ...
