TranscriptomicsA global transcriptional regulatory role for c-Myc in Burkitt's lymphoma cells
Genome-wide location analysis of transcription factor of c-Myc and Max was conducted using RenLab Hu6K array in Daudi cells. In comparison, the GWLA was also done for general transcription factor RNA polymerase II and TAF1, and sequence specific transcription factor E2F1 in the same cell line. Keyw...

TranscriptomicsEfficacy of retinoids in IKZF1-mutated BCR-ABL1 acute lymphoblastic leukemia
Alterations of IKZF1, encoding the lymphoid transcription factor IKAROS, are a hallmark of high risk acute lymphoblastic leukemia (ALL), however the role of IKZF1 alterations in ALL pathogenesis is poorly understood. Here we show that in mouse models of BCR-ABL1 leukemia, Ikzf1 and Arf alterations s...

TranscriptomicsTranscription profiling of in mouse medulloblastomas and generation of tumors from cerebellar grunule neuron precursors
Mice lacking p53 and one or two alleles of the cyclin D-dependent kinase inhibitor p18Ink4c are prone to medulloblastoma development. The tumor frequency is increased by exposing postnatal animals to ionizing radiation at a time when their cerebella are developing. In irradiated mice engineered to e...

TranscriptomicsNovel Oncogenic PDGFRA Mutations in Pediatric High-Grade Gliomas
The outcome for children with high-grade gliomas (HGG) remains dismal, with a two-year survival rate of only 10-30%. Approximately half of pediatric HGGs are diffuse intrinsic pontine glioma (DIPG), a brainstem tumor that arises almost exclusively in children. Genome-wide analyses of copy number i...

TranscriptomicsAtoh1 inhibits neuronal differentiation and collaborates with Gli1 to generate medulloblastoma-initiating cells
The morphogen and mitogen, Sonic Hedgehog, activates a Gli1-dependent transcription program that drives proliferation of granule neuron progenitors (GNPs) within the external germinal layer of the postnatally developing cerebellum. Medulloblastomas with mutations activating the Sonic Hedgehog signa...

TranscriptomicsMethylphenidate exposure induces dopamine neuron loss and activation of microglia in the basal ganglia of mice
Background: Methylphenidate (MPH) a psychostimulant prescribed to manage ADHD symptoms, has been increasingly prescribed to children not meeting the strict criteria for ADHD. It has also been misused as a “cognitive enhancer” and as an alternative to other psychostimulants. Here, we investigate whet...

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...

TranscriptomicsHierarchical synergy of Pten, p53 and Rb pathways in high-grade astrocytoma induced in adult brain
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 ...
