Project description:Transcriptional profiling of human glioma cells comparing control GFP expressing cells with glioma cells transfected with a human PDGF-A gene. The isogenic cell lines were used to study the impact on glioma tumorigenesis and invasion. Goal was to determine the effects of PDGF-A gene transfection on global ES gene expression. Two set of glioma cell lines, LN444 vs LN444/PDGF-A and LN443 vs LN443/PDGF-A. Biological replicates: 2 control replicates, 2 transfected replicates.
Project description:Glioblastoma (GBM) is a deadly disease without effective treatment. Because glioblastoma stem cells (GSCs) contribute to tumor resistance and recurrence, improved treatment of GBM can be achieved by eliminating GSCs through inducing their differentiation. Prior efforts have been focused on studying GSC differentiation towards the astroglial lineage. We used microarrays to detail the global programme of gene expression underlying ZNF117 knockout and identified distinct classes of up-regulated genes during this process.
Project description:Transcriptional profiling of human glioma cells to elucidate the role of chronophin (CIN/PDXP) for glioma pathogenesis three-condition experiment: control cells vs. knockdown and knockdown vs. rescue
Project description:Differential mRNA expression patterns were seen in GSC272-vector compared to GSC272-POSTN shRNA tumors. We used microarrays to POSTN regulated gene expression in glioma stem cells. Gene expression comparisons were shown between: 1. mRNA control from GSC272 glioma stem cells implanted mouse brain tumor at 7 weeks after implantation, and 2. mRNA deplection of POSTN from knock down of POSTN of GSC272 glioma stem cells implanted mouse brain tumor at 7 weeks after implantation.

Project description:Analysis of the effects of targeting NOS2 at the gene expression level. Our studies demonstrated a role for NOS2 in glioma biology through the maintenance of the glioma stem cell phenotype. Microarray results provide novel targets of NOS2 and suggest mechanisms through which NOS2 contributes to glioma stem cell biology. Glioma stem cells isolated from two different human glioma xenografts were infected with a non-targeting control shRNA or two different shRNAs directed against NOS2 (each treatment in each tumor performed in technical duplicates).
