Global transcriptional changes in U87MG glioblastoma cells upon shRNA-mediated TRIM52 knockdown

Project description:shRNA-mediated ablation of the RING-finger protein TRIM52 from multiple glioblastoma cell lines reduces proliferation and tumorigenesis. To identify gene signatures underlying this phenomenon, transcritional profile of TRIM52 knockdown cells was compared to control cells. Upon TRIM52 ablation, we find 278 differentially regulated genes. Gene ontology analysis reveals that many of the upregulated genes are associated with glycolysis and biosynthetic processes.

Transcription profiling array of human glioblastoma cell line U87MG comparing control cells (U87RNAi) with U87shLAPTM5 knockdown cells

Project description:After performing an in-vivo screening with U87 glioblastoma cells transduced with a knockdown library several genes could be identified. LAPTM5 which was one of the candidates was further evaluated. Single knockdown of LAPTM5 in U87MG conferred a pro-invasive phenotype in-vitro and in-vivo. To decipher the underlying pathways U87MG control cells (U87RNAi) and U87shLAPTM5 were analyzed after in-vitro culture by a transcription profiling Array.

Identification of radiation resistence genes by shRNA screen

Project description:To identify genes involved in raditaion resistence in glioblastoma, Decode shRNA Viral screening was performed on U87MG and LN229 glioblastoma cell lines. Cells were irraidated with 2 Gy and then compared to unirradiated cell genomic DNA on Decode custom Agilent barcode arrays.

Expression data from U87MG subclones

Project description:U87MG is a glioblastoma cell line that shows substantial heterogeneity despite long-term passaging. We used microarrays to identify variations in gene expression that are associated with phenotypic differences among subclones derived from U87MG.

Silencing of ASCL1 in U87MG glioma cells

Project description:ASCL1 is known to act as transcriptional activator of notch signaling pathway. We have found that ASCL1 is over expressed in secondary glioblastoma. In order to delineate its functional role in gliomagensis we have used gene silencing approach to identify genes differentially regulated upon ASCL1 down regulation in U87MG glioma cell line.

Transcriptome analysis of CD133 overexpressed U87MG glioblastoma cells

Project description:This study investigated the biological function of CD133 by ectopic expression of CD133 in U87MG cell line. Although CD133 is widely used as a cancer stem cell marker, there are a few studies that examined its own biological functions. While a number of loss-of-function studies about CD133 have shown that CD133 have effects on cancer progression, there are few gain-of-function studies about functions of CD133. Thus, we identified the potential function of CD133 by its overexpression in U87MG glioblastoma cell line. Though there were no significant changes in cell growth and sphere forming ability, elevated IL-1β and its downstream chemokines (CCL3, CXCL3, CXCL5) may function as chemoattractants which affect recruitment of Ly6G+ neutrophils surrounding necrotic regions in vivo and migration of neutrophil-like dHL-60 cells. Taken together, this results imply that CD133 can regulate IL-1β signaling, and promotes the environmental change.

Gene expression data in U87MG cell line transfected with miR-490 overexpression vector PC-490 or its control PCDNA3.1 (+).

Project description:miR-490 is robustly downregulated in GBM tumour samples. This study identifies the genes differentially expressed upon miR-490 overexpression in U87MG glioblastoma cell line. GeneChip PrimeView Human Gene Expression Array was used to assess mRNA expression profile in response to miR-490 overexpression in U87MG cell line.
