Expression of miR-940 in glioma tissues, clinical samples and glioma cell lines. A. The relative expression of miR-940 was determined in samples from the TCGA database (normal tissues, n=5; glioma tissues, n=530). P<0.0001. B. miR-940 expression negatively correlates with glioma grade in the CGGA dataset. P<0.0001. C. miR-940 levels were analyzed in a clinical database (5 NBT samples from traumatic brain injury and 34 glioma tissue samples (18 grade II, 7 grade III and 9 grade IV tissues)). D, E. miR-940 expression was lower in glioma tissue than in NBT as determined by FISH (Normal vs Glioma, P<0.0001) (scale bars, 50 μm). F. qRT-PCR analysis of miR-940 expression in different cell lines (NHAs and six glioma cell lines). The data are expressed as the mean ± s.e.m.
