Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Glioblastoma multiforme (GBM) is a highly malignant primary central nervous neoplasm characterized by tumor cell invasion, robust angiogenesis, and a mean survival of 15 months. Human cytomegalovirus (HCMV) infection is present in > 90% of GBMs, although the role the virus plays in GBM pathogenesis is unclear. We report here that a majority of human GBM tumors express HCMV pp71, which has previously been found to promote cell cycle progression and viral replication, and that pp71 is expressed preferentially within the CD133+ cancer stem cell-like subpopulation. Overexpression of pp71 in adult neural precursor cells (NPCs) resulted in a dramatic induction of stem cell factor (SCF) gene expression, which has been identified as an important pro-angiogenic factor in GBM.
Publication Title
Cytomegalovirus pp71 protein is expressed in human glioblastoma and promotes pro-angiogenic signaling by activation of stem cell factor.

Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We introduced the HCMV IE1 gene into a mouse model of spontaneous glioma driven by p53KD and overexpression of Ras and PDGF and compared the transcriptomes of mouse gliomas +/- IE1. The following plasmids were utilized for glioma induction in equal parts: pT2/C-Luc/PGK-SB100, pT2/Cag-NrasV12, pT2/shP53/GFP4/mPDGF, and pT2/Cag-IE1 or pT2/C-Neo.

Description
Differentiation of human skeletal stem cells (hMSC) into osteoblasts is regulated by a few well described transcription factors. Our study used clustering and gene expression data to identify a novel transcription factor. ZNF25, which we showed is involved in osteoblast differentiation.
Publication Title
Transcription factor ZNF25 is associated with osteoblast differentiation of human skeletal stem cells.

Description
Directing differentiation of human embryonic stem cells (hESC) into specific cell types using an easy and reproducible protocol is a perquisite for the clinical use of hESC in regenerative medicine protocols. Here, we report the generation of mesodermal cells with differentiation potential to myocytes, osteoblasts, chondrocytes and adipocytes. We demonstrate that during hESC differentiation as embryoid bodies (EB), inhibition of TGF-b/Activin/Nodal signaling using SB-431542 (SB) markedly up-regulated paraxial mesodermal markers (TBX6, TBX5), early myogenic transcriptional factors (Myf5, Pax7) as well as myocyte committed markers (NCAM, CD34, Desmin, MHC (fast), alpha-smooth muscle actin, Nkx2.5, cTNT). Establishing EB outgrowth cultures (SB-OG) in the presence of SB (1 uM) led to further enrichment of cells expressing markers for myocyte progenitor cell: CD34+ (33%), NCAM+ (CD56) (73%), PAX7 (25%) and mature myocyte proteins (MYOD1, tropomyocin, fast MHC an

Description
Dose-dependent ileal gene expression was examined following repeated exposure (every 4 days for 28 days) to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). These data were used to examine the effect of repeated TCDD exposure on gene expression in the intestinal epithelium of C57BL/6 male mice. Overall design: Three biological replicates for each dose (0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30) of TCDD and sesame oil vehicle

Description
Epithelial to mesenchymal transition (EMT) is activated during cancer invasion and metastasis, enriches for cancer stem cells (CSCs), and contributes to therapeutic resistance and disease recurrence. The epithelial cell line MCF7, can be induced to undergo EMT with the induction of PKC by PMA. 5-10% of the resulting cells have a CSC phenotype. This study looks at the transcriptome of these cells and how it differs from cells with a non-CSC phenotype.
