(Submitter supplied) Arsenic trioxide (ATO) treatment leads to activation of mRNA translation through the MAPK-interacting kinase (MNK) signaling pathway. Polysomal fractionation and microarray analysis allows for identification of transcripts undergoing active translation. We identified the genes differentially enriched in untreated and ATO treated fractions. In this dataset, we include expression data in untreated and ATO treated LN229 cells using either the total or polysomal RNA.

(Submitter supplied) To identify signaling pathways that are differentially regulated in human gliomas, a microarray analysis on 30 brain tumor samples (12 primary glioblastomas (GBM), 3 secondary glioblastomas (GBM-2), 8 astrocytomas (Astro) and 7 oligodendrogliomas (Oligo)) and on 5 glioblastoma cell lines (LN018, LN215, LN229, LN319 and BS149) was performed. Normal brain tissue (NB) and normal human astrocytes (NHA) were used as a control. more...

(Submitter supplied) Tumor heterogeneity of high-grade glioma (HGG) is recognized by four clinically relevant subtypes based on core gene signatures. However, molecular signaling in glioma stem cells (GSCs) in individual HGG subtypes is poorly characterized. Here we identified and characterized two mutually exclusive GSC subtypes with distinct dysregulated signaling pathways. Analysis of mRNA profiles distinguished proneural (PN) from mesenchymal (Mes) GSCs and revealed a pronounced correlation with the corresponding PN or Mes HGGs. more...

(Submitter supplied) Glioblastoma (GBM) is the most lethal primary brain tumor in adults with a median survival of around 15 months. A potential treatment strategy involves targeting glioma stem-like cells (GSCs) that are able to initiate, maintain, and repopulate the tumor mass. Here, we identify ACT001, a parthenolide derivative, targeting GSCs through regulation of adipocyte enhancer binding protein 1 (AEBP1) signaling.GSCs exhibit high response to ACT001 in compared with normal human astrocytes. more...

(Submitter supplied) BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) has a high mortality rate due to the lack of effective treatments and drugs. Arsenic trioxide (As2O3, ATO, arsenious acid), which has been proved to successfully treat acute promyelocytic leukemia (APL), was recently reported to show therapeutic potential in solid tumors including liver cancer. Although the mechanistic effects of ATO in APL are established, its anticancer mechanism of action in HCC is still unclear. more...

(Submitter supplied) The phosphorylation of eIF4E1 at serine 209 by MNK1 or MNK2 has been shown to initiate oncogenic mRNA translation, a process that favours cancer development and maintenance. Here, we interrogate the MNK-eIF4E axis in diffuse large B-cell lymphoma (DLBCL) and show a distinct distribution of MNK1 and MNK2 in germinal centre B-cell (GCB) and activated B-cell (ABC) DLBCL. Despite displaying a differential distribution in GCB and ABC, both MNKs functionally complement each other to sustain cell survival. more...

(Submitter supplied) To investigate the effect of Ato-C on gene expression, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to suppress the cell proliferation of Ph+ CML cell lines. K562, KU-812 and MEG-A2 cells were treated with ATO, CDDP or Ato-C for 24 h in vitro.

(Submitter supplied) Gliomas are the most common primary brain tumor in humans. Low-grade gliomas (WHO grade II) invariably progress to high-grade gliomas (WHO grade III or IV). Although malignant progression may take many years, the survival rate after transformation to a high-grade glioma is poor, often only 12-15 months. In this data set, we have identified low-grade gliomas that have progressed to high-grade gliomas or high-grade gliomas that have progressed from low-grade gliomas. more...

(Submitter supplied) Dysregulated metabolism in glioblastoma (GBM), the deadliest brain tumor of adults, 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 exploit metabolic rewiring to sustain tumor progression, we interrogated the transcriptome, the metabolome and the glycoproteome of human subgroup-specific GBM stem cells (GSCs). more...
