Project description:Glioblastomas show heterogeneous histological features. These distinct phenotypic states are thought to be associated with the presence of glioma stem cells (GSCs), which are highly tumorigenic and self-renewing sub-population of tumor cells that have different functional characteristics. We found that TUG1, a long non-coding RNA (lncRNA), plays pivotal roles in maintaining the self-renewal properties of GSC. Some lncRNAs are known to act as a miRNA sponge in the cytoplasm, where lncRNAs bind to miRNAs and quench their activity. To investigate miRNA expression profiling in GSC upon TUG1 inhibition, we have performed microarray experiment using SurePrint G3 Human miRNA 8x60K Microarray (G4872A, Agilent Technologies).

Project description:Glioblastomas show heterogeneous histological features. These distinct phenotypic states are thought to be originated by the glioma stem cells (GSCs), which are highly tumorigenic and self-renewing sub-population of tumor cells that have different functional characteristics. We found TUG1, a large non-coding RNA (lncRNA) is highly expressed in GSCs. TUG1 was reported to interact with PRC2 via its exon 2 and represses its target gene expression in trans. In order to identify the genetic loci enriched with TUG1 in GSC, we performed modified RNA pull-down assay coupled with promoter-microarray analysis using BrU-labeled TUG1.

Project description:The evolutionary conserved Taurine Upregulated Gene 1 (TUG1) is a ubiquitously expressed gene that is one of the highest expressed genes in human and rodent endothelial cells (ECs). We here show that TUG1 expression decreases significantly in aging mouse carotid artery ECs and human ECs in vitro, indicating a potential role in the aging endothelial vasculature system. We therefore investigated if, and how, TUG1 might function in aging ECs, but despite extensive phenotyping found no alterations in basal EC proliferation, apoptosis, barrier function, migration, mitochondrial function, or monocyte adhesion upon TUG1 silencing in vitro. TUG1 knockdown did slightly and significantly decrease cumulative sprout length upon vascular endothelial growth factor A stimulation in human umbilical vein endothelial cells (HUVECs), though TUG1-silenced HUVECs displayed no transcriptome-wide mRNA expression changes explaining this effect. Further, ectopic expression of the highly conserved and recently discovered 153 amino acid protein translated from certain TUG1 transcript isoforms did not alter angiogenic sprouting in vitro. Our data show that, despite a high expression and strong evolutionary conservation of both the TUG1 locus and the protein sequence it encodes, TUG1 does not seem to play a major role in basic endothelial cell function.

Project description:To identify a novel miRNA that is aberrantly expressed in GICs, we analyzed differences in miRNA expression between the human GICs and glioma cell lines and neural stem cells by miRNA microarrays. We examined the miRNA expression profiles of five human GICs that were obtained from human glioma samples and two human glioma cell lines, U87 and U251, and NSC (neural stem cells) as a control.
