In ependymomas, gene expression negatively correlated with the expression of cluster members, e.g., miR-106b-MYCC r = −0.42, miR-106b-MYCN r = −0.61, miR-106b-E2F2 r = −0.51, miR-106b-E2F3 r = −0.58, miR-93-MYCN r = −0.47, miR-25-MYCN r = −0.47, miR-25-E2F2 r = −0.49, miR-25-E2F3 r = −0.52. The gene discussed is MYC; the disease is ependymoma.
