Since miR-211 and pM treatments caused increased apoptosis via caspase-9/3 activation in glioma cells and CSC (Figures 2 and 3), we examined the apoptotic DNA laddering profile of miR-211- and pM-treated glioma CSC alone or after subjecting them to a sublethal dose of temozolomide. This evidence concerns the gene CASP9 and central nervous system cancer.
