TranscriptomicsMyc and N-myc induce distinct medulloblastoma subgroups via Miz1
Medulloblastomas (MBs) are cerebellar tumors that can be classified into molecularly distinct subgroups that differ in pathology and prognosis. The mechanisms that underlie subgroup specification are largely unknown. While human SHH MBs express MYCN, Group3 (G3) MBs are associated with c-MYC (MYC) o...

TranscriptomicsThe MYC-MIZ1 interaction defines tumor identity
Medulloblastoma (MB) is the most common malignant brain tumor. MB is a cerebellar tumor that occurs mostly in children between the ages of 3-7 years but also in adults. Human MBs are classified into four subgroups: Wingless (WNT), Sonic Hedgehog (SHH), Group 3 (G3) and G4, each of which with distinc...

TranscriptomicsA mouse model of the most aggressive subgroup of human medulloblastoma [Mouse430_2]
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...

TranscriptomicsA mouse model of the most aggressive subgroup of human medulloblastoma [HT_MG-430_PM]
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...

TranscriptomicsIn vivo electroporation-based conditional oncogenic activation implicates multiple distinct cellular origins for Group3 medulloblastoma
We examined the transformation susceptibility of different cerebellar stem/progenitors by developing several new Group3 medulloblastoma murine models using orthotopic transplantation and in utero electroporation (EP)-based in vivo gene transfer with Cre/LoxP-mediated conditional Myc gene activation ...

TranscriptomicsMiz1 is required to maintain autophagic flux_2
To isolate neuronal progenitor cells (NPCs), forebrains of E13.5 Miz1+/+ or Miz1-delta-POZ embryos were cut in small pieces, digested with trypsin and filtered through sterile gauze. Cells were cultivated in 2:1 DMEM/F12 supplemented with 1xB27 (Life technologies), 20 ng/ul EGF (Biomol), 20 ng/?l ba...

TranscriptomicsMiz1 is required to maintain physiological levels of autophagic flux_1
Mice: knock-out of the Miz1 POZ-domain in brain (Miz1DPOZNes) and control mice. The RNA expression in cerebella of of old Miz1 delta POZ mice (1.5 years), old control mice (1.5 years), young Miz1 delta POZ mice (5.5 weeks) and young control mice (5.5 weeks) was compared

GenomicsThe Genomic Analysis of Medulloblastoma

Medulloblastoma is a heterogenous disease made up of at least four distinct subtypes of disease which appear to exploit and disrupt naturally occurring developmental pathways of cellular growth and hindbrain development. To better understand the driver mutations of this disease, we performed whol...

TranscriptomicsNovel mutations target distinct subgroups of medulloblastoma.
Medulloblastoma is a malignant childhood brain tumour comprising four discrete subgroups. To identify mutations that drive medulloblastoma we sequenced the entire genomes of 37 tumours and matched normal blood. One hundred and thirty-six genes harbouring somatic mutations in this discovery set wer...

GenomicsMiz1 is required to maintain autophagic flux
Miz1 is a zinc finger protein that regulates expression of cell cycle inhibitors as part of a complex with Myc. Cell cycle-independent functions of Miz1 are poorly understood. Here, we use a Nestin-Cre transgene to delete an essential domain of Miz1 in the central nervous system (Miz1M-NM-^TPOZNes)....
