(Submitter supplied) 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. more...

(Submitter supplied) Primary human GBM stem like cells were infected with HCMV TR strain (MOI=1) and treated with IE siRNA (a combination of oligos targeting IE1 and IE2 HCMV genes) 72 hours following siRNA treatment, RNA was harvested using Qiagen and divided equally for profiling using Affymetrix arrays and HCMV arrays.

(Submitter supplied) 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. Primary human glioma stem cells were maintained in neurosphere growth conditions, treated with IE1 and control siRNA for 48-72h prior to RNA harvesting. more...

(Submitter supplied) We have previously established two sibling glioma subclones, J3T-1 and J3T-2, showing distinct invasive and angiogenic phenotypes. J3T-1, expressing high annexin A2, demonstrates robust angiogenesis and tumor invasion around neovasculature. J3T-2, expressing low annexin A2, demonstrates diffuse invasion along white matter tracts. Knockdown of annexin A2 in J3T-1 (J3T-1shA) resulted in diffuse invasion pattern, and overexpression of annexin A2 in J3T-2 (J3T-2A) showed prominent angiogenesis. more...

(Submitter supplied) The human cytomegalovirus (HCMV) encodes the chemokine receptor US28 that exhibits constitutive activity. NIH-3T3 cells stably transfected with US28 present a pro-angiogenic and transformed phenotype both in vitro and in vivo. We used gene expression profiling to determine how US28 constitutive activity modulates expression of genes compared to mock-transfected cells. Keywords: Comparison of stably transfected cell lines

Analysis of fibroblast NIH-3T3 cells expressing the human cytomegalovirus (HCMV) chemokine receptor U28. HCMV proteins are present in malignancies such as colon cancer. U28 activates inflammatory and proliferative signaling pathways. Results provide insight into the role of U28 in oncogenesis.

(Submitter supplied) We employed RNA-seq to map the transcriptome of human MRC5 fibroblasts during HCMV infection with AD169 and AD169-ΔUL26 strains. These data will highlight the ways in which the HCMV UL26 protein alters host gene transcripton during infection.

(Submitter supplied) In this study, we explored the transcriptomic consequences of strong activation of the Notch pathway in embryonic human neural stem cells and in gliomas. For this we used a forced expression of the Notch intracellular domain (NICD). Glioblastoma multiforms (GBMs) are highly vascularized brain tumors containing a subpopulation of multipotent cancer stem cells. These cells closely interact with endothelial cells in neurovascular niches. more...
