(Submitter supplied) CSCs differentially secrete the BMP antagonist Gremlin1 compared to non-stem glioma populations. Knockdown of Gremlin1 decreases CSC proliferation and tumorigenicity, establishing Gremlin1 as an essential effector for CSC maintenance. We used a microarray to determine the gene expression programs that are activated downstream of Gremlin1 that might be responsible for CSC maintenance.

(Submitter supplied) In this study, we describe a novel relationship between glioblastoma CSCs and the Notch pathway, which involves the constitutive activation of STAT3 and NF-κB signaling. We demonstrate that adherent glioma CSCs exhibit characteristics previously described for CSCs grown in suspension culture. The expression of CD133, Sox2 and Nestin increased when compared to glioma cells grown in monolayer, and the adherent CSCs were ~100 times more tumorigenic in vivo than monolayer cultured glioma cells. more...

(Submitter supplied) The recent identification of cancer stem cells (CSCs) in multiple human cancers provides a new inroad to understanding tumorigenesis at the cellular level. CSCs are defined by their characteristics of self-renewal, multipotentiality, and tumor initiation upon transplantation. By testing for these defining characteristics, we provide evidence for the existence of CSCs in a transgenic mouse model of glioma, S100ß-verbB;Trp53. 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) Analysis of the function of Tlx in regulating brain tumor stem cells (BTSCs) at the gene expression level. Based on our knowledge, we know that Tlx is specifically expressed in the neural stem cells in mouse brain. It also functionally regulates neurogenesis during the postnatal stages. The hypothesis tested in the present study is that Tlx influences the maintenance and progression of mouse brain gliomas through regulating the self-renewal of BTSCs and it is also a specific marker of brain tumor stem cells (BTSCs). more...

(Submitter supplied) Fibroblast cells were cultured from human skin, either tumor (basal cell carcinoma) or non-tumor tissue. Cells were propagated for several passages in culture, then switched to low (0.1%) serum conditions for 48 hours prior to mRNA harvest. Reference for all arrays was Stratagene Universal Human Reference RNA. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. more...

(Submitter supplied) Dataset contains samples that are all fibroblast cells that have been cultured from fresh human tissue. Fibroblasts were derived either from tumor (basal cell carcinoma) or non-tumor (control) tissue. Samples were maintained in DMEM, 10% FBS, glutamine, pen/strep and passaged for 4 passages before RNA harvest was performed using Invitrogen FastTrack. Reference channel RNA is the same for each array in the dataset and is Stratagene Universal Reference RNA. more...
