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.
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).
Project description:There is little overlap on publicily avaiable gene signatures and it is unclear how relevant these are to glioma biology. MYC is a very dynamically regulated gene, and it's gene signature will vary with respect to cell context. To determine what genes fall within the MYC signature of glioma, we performed ChIP-SEQ upon 4 different glioma PDX with two different MYC antibodies. The overlapping enriched genes will provide context of a MYC signature within the context of glioma.
