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:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs. One-condition experment, gene expression of 3A6
Project description:GfapCRE:Rpl22HA mice were intracranially implanted with GL261 glioma cells (GBM) or injected with PBS (sham). Seventeen days later, RNA was retrieved from mouse brain extract (input) by anti-HA immunoprecipitation
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression. Two-condition experiment, Normoxic MSCs vs. Hypoxic MSCs.
Project description:This work lays the foundation for the intratumoral immune infiltrates of glioma patients analyzed at a single cell level with the dual purpose of establishing the relevance of a new mouse model of GBM with regard to the patient disease. The aim of this study was to determine the level of concordance between the spontaneous and implanted Qk/trp53/Pten (QPP) triple-knockout mouse GBM model and human glioma samples in regard to their immune infiltrates.We analyzed a cohort of fifteen spontaneous QPP mice, nine implanted QPP mice and 10 glioma patients histopathologically. Furthermore, we analyzed three spontaneous QPP mice, thee implanted QPP mice, and 10 glioma patients by single cell RNA sequencing. We found that the QPP model recapitulates human GBM regarding the major immune components including a predominantly myeloid cell population of monocytes, macrophages, and resting dendritic cells, with minor populations of T, B, and NK cells. In addition, the complexity of the myeloid cell populations is preserved between the QPP model and the human disease.
