MetabolomicsAberrant L-Fucose accumulation and increased core fucosylation are metabolic liabilities in mesenchymal glioblastoma (Xenograft assays)

Glioblastoma (GBM) is a common and deadly form of brain tumor in adults. Dysregulated metabolism in GBM offers an opportunity to deploy metabolic interventions as precise therapeutic strategies. To identify the molecular drivers and the modalities by which different molecular subgroups of GBM exp...

TranscriptomicsCopy number analysis of human glioblastoma multiforme
Copy number analysis of human GBM samples were performed, and a high frequency of deletions of the PTPRD gene on chromosome 9p23-24.1 were identified. Keywords: SNP microarray, glioblastoma multiforme, copy number, amplification, deletion Genomic DNA from 58 GBM tumor samples were hybridized to Aff...

TranscriptomicsProfiling by array of human Glioblastoma multiforme (GBM) tumor samples to asses the intra-tumoral heterogeneity in genomic copy number aberrations
Glioblastoma multiforme (GBM) is a highly heterogeneous disease that shows an wide range of genetic abnormalities in comparison to other astrocytic tumors. We have extracted between 4 and 8 tumor subsamples from different areas of the malignant tissue that were at least 1cm apart. Our aim to asses t...

TranscriptomicsIdentification of novel genes associated with human glioblastoma (GBM) tumor-initiating cells (TICs)
Most patients affected by Glioblastoma multiforme (GBM) experience a recurrence of the disease because of the spreading of tumor-initiating cells (TICs) beyond surgical boundary. Unveiling and targeting molecular mechanisms causing this process is a logic goal to impair GBM killing ability. In an or...

TranscriptomicsGlioblastoma microvesicles transport RNA and proteins
Glioblastoma tumour cells release microvesicles (exosomes) containing mRNA, miRNA and angiogenic proteins. These microvesicles are taken up by normal host cells, such as brain microvascular endothelial cells. By incorporating an mRNA for a reporter protein into these microvesicles, we demonstrate th...

TranscriptomicsSingle cell derived clonal analysis of human glioblastoma links functional and genomic heterogeneity
Single cell derived clones were extracted from four glioblastoma tumors using fluorescence activated cell sorting with CD15 and CD133 markers. Unsorted bulk tumors were also derived. Gene expression analysis of clones of tumor GBM-482 involved comparison between TMZ resistant (n=5) and sensitive (n=...

ProteomicsIdentification of tumor antigens among the HLA peptidomes of Glioblastoma tumors and plasma
Glioblastoma multiforme (GBM) is the most aggressive brain tumor with poor prognosis to most patients. Immunotherapy of GBM is a potentially beneficial treatment option, whose optimal implementation may depend on familiarity with tumor specific antigens, presented as HLA peptides by the GBM cells. F...

TranscriptomicsLOC283731 promoter hypermethylation prognosticates survival after radiochemotherapy in IDH1 wild-type glioblastoma patients
MGMT promoter methylation status is currently the only established molecular prognosticator in IDH wild-type glioblastoma multiforme (GBM). Therefore, we aimed to discover novel therapy-associated epigenetic biomarkers. After enrichment for hypermethylated fractions using methyl-CpG-immunoprecipitat...

TranscriptomicsPatient specific orthotopic glioblastoma xenograft models recapitulate the histopathology and biology of human glioblastomas in situ (CGH)
Frequent discrepancies between preclinical and clinical results of anti-cancer agents demand a reliable translational platform that can precisely recapitulate the biology of human cancers. Another critical unmet need is the ability to predict therapeutic responses for individual patients. Toward thi...
