When all samples were divided into IDH1 gene mutated ( IDH1mut , n = 18) and IDH1 wild-type ( IDH1wt , n = 78) gliomas, we observed a tendency of lower expression of CASC2 in IDH1wt ( p = 0.053) and highly significant relationship between higher miR-21 expression and IDH1wt gliomas ( p < 0.0001) ( Figure 2 A,B). 2.3.
