(Submitter supplied) There is evidence that brain tumor cells may hijack self-renewal mechanism that regulate stem cell maintenance during normal development. Notch signaling is fundamental for maintaining normal neural stem cells in an undifferentiated state and has been implicated in in the maintenance of brain tumor stem cells as well. We used microarrays to detail the global gene expression program in murine brain tumors lacking RBPjk, an indispensable mediator of the Notch signaling pathway in the cell nucleus.

(Submitter supplied) Bladder cancer (BC) is a highly prevalent human disease in which Rb pathway inactivation and epigenetic alterations are common events. However, the connection between these two processes is still poorly understood. Here we show that the in vivo inactivation of all Rb family genes in the mouse urothelium is sufficient to initiate BC development. The characterization of the mouse tumors revealed multiple molecular features of human BC, including the activation of E2F transcription factor and subsequent Ezh2 expression, and the activation of several signaling pathways previously identified as highly relevant in urothelial tumors. more...

(Submitter supplied) We have determined that tenascin C (TNC) regulates the growth of human brain tumor initiating cells (BTICs). We have identified novel mechanisms by which TNC regulates BTIC growth. Analysis of the array data identified a number of genes that were altered with TNC treatment that could potentially regulate BTIC growth. The study provides the mechanistic basis for the regulation of BTIC growth with TNC.

(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...

(Submitter supplied) Brain tumors are among the most malignant cancers and can arise from neural stem cells or oligodendrocyte progenitor cells (OPCs). Glioma-propagating cells (GPCs) that have stem-like properties have been derived from tumor variants such as glioblastoma multiforme (GBM) and oligodendroglial tumors, the latter being more chemosensitive with better prognosis. It has been suggested that such differences in chemosensitivity arise from the different profiles of OPCs versus neural stem cells. more...

(Submitter supplied) Glioblastomas coopt stem cell regulatory pathways to maintain brain tumor initiating cells (BTICs), also known as cancer stem cells. Notch signaling has been a molecular target in BTICs, but Notch antagonists have demonstrated limited efficacy in clinical trials. RBPJ is considered a central transcriptional mediator of Notch activity. Here, we report that pharmacologic Notch inhibitors were less effective than targeting RBPJ in suppressing tumor growth. more...

(Submitter supplied) Glioblastomas display hierarchies with self-renewing cancer stem-like cells (CSCs). RNA sequencing and enhancer mapping revealed regulatory programs unique to CSCs causing upregulation of the iron transporter transferrin, the top differentially expressed gene compared to tissue-specific progenitors. Direct interrogation of iron uptake demonstrated CSCs potently extract iron from the microenvironment more effectively than other tumor cells. more...

(Submitter supplied) The proto-oncogene MYCN is mis-expressed in various types of human brain tumors. To clarify how developmental and regional differences influence transformation, we transduced wild-type or mutationally-stabilized murine N-mycT58A into neural stem cells (NSCs) from perinatal murine cerebellum, brain stem and forebrain. Transplantation of Nmyc WT NSCs was insufficient for tumor formation. N-mycT58A cerebellar and brain stem NSCs generated medulloblastoma/primitive neuroectodermal tumors, whereas forebrain NSCs developed diffuse glioma. more...

(Submitter supplied) Notch signaling plays a pivotal role in liver development and aberrant Notch signaling may lead to hepatocellular (HCC) or cholangiocellular carcinoma (CCA) development. Using whole exome sequencing of 54 human HCC samples, we discovered 19 somatic missense mutations in 15 different Notch pathway genes affecting 24.6% (14 of 57) of patients. Prediction of functional impact of these Notch pathway mutations revealed HES5-R31G to have high relevance.
