Development of gene expression signatures for miR-340 overexpressing human glioma-initiating cells (GICs)

To identify functional targets of miR-340, we compared the gene expression profiles of miR-340 overexpressing human GICs with the profiles of their parental cells. The precursor form of miR-340 or control miRNA was overexpressed in glioma cells using miRNA lentiviral particles. The cells were incubated with recombinant virus at 37°C for 12 hr and cultured in the presence of puromycin for 3 days.
