Expression data from transfection of U87 glioma cells with miR-376a* for 24 hours

ABSTRACT: Enforced expression of miRNAs in cells leads to down-regulation of several mRNAs, which harbour binding sites in their 3'UTRs for the overexpressed miRNA and represent potential target genes of the miRNA We transfected unedited miR-376a* (376a*A) and edited miR-376a* (376a*G) into U87 cells to identify transcripts down-regulated by each in comparison to control miRNA transfection. The aim was to identify target genes directly subject to regulation by miR-376a*A and by miR-376a*G

Expression data from transfection of U87 glioma cells with miR-376a* for 24 hours

The aim was to identify target genes directly subject to regulation by miR-376a*A and by miR-376a*G U87 cells (100,000) were transfected with 50 nM of miR-376a*A, miR-376a*G or miR-control. Following incubation for 24 hours, total RNA was isolated from transfected cells. For each (miR-376a*A or miR-376a*G), genes differentially expressed upon miRNA transfection were determined based on comparison with miR-control-transfected samples. Biological triplicates were used for each sample type.

Expression data from transfection of U87 glioma cells with miR-376a* for 72 hours

Project description:Several biological pathways can be under the regulation of miRNAs. These pathways can be indentified by the enforced expression of a miRNA and analysing the expression data for enrichment of specific pathways represented among the genes differentially expressed upon miRNA overexpression. We transfected unedited miR-376a* (376a*A) and edited miR-376a* (376a*G) into U87 cells to identify differentially regulated transcripts. List of differentially expressed genes were subject to pathway enrichment analysis to identify specific biological processes regulated by each of miR-376a*A and miR-376a*G. U87 cells (100,000) were transfected with 50 nM of miR-376a*A, miR-376a*G or miR-control. Following incubation for 72 hours, total RNA was isolated from transfected cells. For each (miR-376a*A or miR-376a*G), genes differentially expressed upon miRNA transfection were determined based on comparison with miR-control-transfected samples. Biological triplicates were used for each sample type.

Discovery of Gene Expression Signature in the Overexpression of miR-145 in U87 glioma cell.

Project description:We have employed whole RNA microarray expression profiling as a discovery platform to identify genes regulated by overexpression of miR-145 in U87 glioma cell. Lentivirus containing miR-145 coding sequence was infected to U87 cell to make U87 overexpressing miR-145. We did genome microarray between U87 and U87 overexpressing miR-145.
