Methylation profiling of Glioma Stem Cell lines vs GBM FFPE tissue biopsies and foetal Neural Stem Cell lines

(Submitter supplied) The DNA methylation profiles of Glioma Stem Cell (GSC) lines were investigated in order to find the stem cell signature associated to glioblastoma (GBM). This goal was achieved through the comparison of GSC methylation data with FFPE-GBM biopsies and human foetal Neural Stem Cell (NSC) lines profiles.

Genome variation profiling of Glioma Stem Cell lines

(Submitter supplied) Glioblastoma multiforme (GBM), the most common and malignant type of glioma, is characterized by a poor prognosis and the lack of an effective treatment, which are due to a small sub-population of cells with stem-like properties, termed glioma stem cells (GSCs). The term “multiforme” describes the histological feature of this tumor, i.e. the cellular and morphological heterogeneity. At the molecular level multiple layers of alterations may reflect this heterogeneity providing together the driving force of tumor initiation and development. more...

Detailed Longitudinal Sampling of Glioma Stem Cells In Situ Reveals Chr7 Gain and Chr10 Loss As Repeated Events in Primary Tumor Formation and Recurrence (expression)

(Submitter supplied) In this study, we developed an extensive dataset for a GBM case via the generation of polyclonal and monoclonal glioma stem cell lines from initial diagnosis, as well as from multiple sections of distant tumor locations of the deceased patient’s brain following tumor recurrence. Our analyses revealed the tissue-wide expansion of a new clone in the recurrent tumor as well as chromosome 7 gain and chromosome 10 loss as repeated genomic events in primary and recurrent disease. more...

Cooperative actions of p53 and Pten in normal and neoplastic progenitor cell renewal and differentiation

(Submitter supplied) Glioblastoma (GBM) is a highly lethal brain tumor presenting as one of two subtypes with distinct clinical histories and molecular profiles. The primary GBM subtype presents acutely as high-grade disease that typically harbors EGFR, PTEN and Ink4a/Arf mutations, and the secondary GBM subtype evolves from the slow progression of low-grade disease that classically possesses PDGF and p53 events1. Here, we show that concomitant CNS-specific deletion of p53 and Pten in the mouse CNS generates a penetrant acute-onset high-grade malignant glioma phenotype with striking clinical, pathological and molecular resemblance to primary GBM in humans. more...

Identification and molecular characterization of distinct glioblastoma cancer stem cell populations

(Submitter supplied) Malignant glioblastoma (GBM) is a highly aggressive brain tumor with a dismal prognosis and limited therapeutic options. Genomic profiling of GBM samples in the TCGA database has identified four molecular subtypes (Proneural, Neural, Classical and Mesenchymal), which may arise from different glioblastoma stem-like cell (GSC) populations. In the present study, we identify two GSC populations that produce GBM tumors by subcutaneous and intracranial injection with identical histological features. more...

Molecular analysis of ex-vivo CD133+ GBM cells revealed a common invasive and angiogenic profile but different proliferative signatures among high grade gliomas.

(Submitter supplied) Background: Gliomas are the most common type of primary brain tumours, and in this group glioblastomas (GBMs) are the higher-grade gliomas with fast progression and unfortunate prognosis. Two major aspects of glioma biology that contributes to its awful prognosis are the formation of new blood vessels through the process of angiogenesis and the invasion of glioma cells. Despite of advances, two-year survival for GBM patients with optimal therapy is less than 30%. more...

Comparison study of glioma stem cells and adult human neural stem cells

(Submitter supplied) Glioblastoma, the most common and malignant brain tumor, harbors stem-like cells that self-renew and propagate upon serial transplantation. Although they share functional, morphological and developmental similarities to adult brain neural stem cells, stem cell characteristic pathways contributing to glioblastoma stem-like cells have not been consistently determined. Towards this goal we have provided an internally coherent molecular reference that compares adult neural and glioblastoma stem cells cultivated under identical conditions. more...
