microRNA expression in lower grade gliomas compared with glioblastoma. Mean log2 (fold change) from normal brain for the tumor types with n>3 in our data set (subependymal giant cell astrocytoma, pilocytoic astrocytoma, pleomorphic xanthoastrocytoma, ganglioglioma, and dysembryoplastic neuroepithelial tumor)) shows similar directionality in expression to previous studies of glioblastoma (GBM) summarized in a recent meta-analysis.35
