(Submitter supplied) For in vivo experiments GFP+ G144 human GBM cells were injected in the caudoputament of CD-1 nude mice. After tumour formation, GFP+ G144 cells were acultely purified from microdissected mouse brain regions (tumour bulk, corpus callosum, striatum) and sequenced to determine gene expression profiles of the different invasive populations. In vitro G144 cells engineered to express inducible SOX10 vector were exposed to Doxycyline for two days and sequenced to determine gene expression profiles following SOX10 overexpression.

(Submitter supplied) Characterization of the tumor border microenvironment is critical for improving prognosis in patients with GBM. Here, we compared microRNA (miRNA) expression in samples from the tumor, tumor border, and peripheral region far from tumor mass by miRNA microarray. The top three of miRNAs showing higher expression in the tumor border were related to oligodendrocyte differentiation, and pathologically oligodendrocyte lineage cells were increased in the border, where numbers of macrophages and microglia also colocalized. more...

(Submitter supplied) Glioblastomas in adult patients are classified into four subtypes, IDH, MES, RTK I, and RTK II, based on DNA-methylation and RNA-expression data. Tumour subtype transitions are common during treatment, and transitions to the mesenchymal (MES) subtype are associated with therapy resistance and adverse prognosis. Here, we present DNA methylome and histone modification data of glioblastoma primary tumours and find that glioblastoma subtypes differ in their enhancer landscapes. more...

(Submitter supplied) Tissue progenitors maintain the integrity of organ systems through aging and stress. The brain’s white matter regions experience ischemic lesions and age-dependent degeneration. Brain white matter contains progenitors, oligodendrocyte precursor cells (OPCs), which can repair some insults. The response of OPCs to white matter ischemia and aging is not known. We characterized the response of OPCs to white matter stroke using OPC reporter mice, cell migration tracking, OPC specific RNA sequencing, and mechanistic studies in candidate biochemical pathways in the aged brain. more...

(Submitter supplied) Trisomy 21 (Ts21) or Down syndrome (DS) is the most common genetic cause of intellectual disability. To investigate the consequences of Ts21 on human brain development, we have systematically analyzed the transcriptome of dorsolateral prefrontal cortex (DFC) and cerebellar cortex (CBC) using exon array mapping in DS and matched euploid control brains spanning from prenatal development to adulthood. We identify hundreds of differentially expressed (DEX) genes in the DS brains, many of which exhibit temporal changes in expression over the lifespan. To gain insight into how these DEX genes may cause specific DS phenotypes, we identified functional modules of co-expressed genes using several different bioinformatics approaches, including WGCNA and gene ontology analysis. A module comprised of genes associated with myelination, including those dynamically expressed over the course of oligodendrocyte development, was amongst those with the great levels of differential gene expression. Using Ts65Dn mouse line, the most common rodent model of DS, w e observed significant and novel defects in oligodendrocyte maturation and myelin ultrastructure; establishing a correlative proof-of-principle implicating myelin dysgenesis in DS. Thus, examination of the spatio-temporal transcriptome predicts specific cellular and functional events in the DS brain and is an outstanding resource for determining putative mechanisms involved in the neuropathology of DS.
