Fig. 1From: Molecular analysis of pediatric brain tumors identifies microRNAs in pilocytic astrocytomas that target the MAPK and NF-κB pathwaysHierarchical clustering of microRNA and mRNA expression stratifies tumor subgroups. Unsupervised hierarchal clustering (Euclidean method) was performed on (a) microRNA and (b) mRNA expression data. Tumors represented as: PA-pilocytic astrocytoma, PGNT-papillary glioneuronal tumor, DA-diffuse astrocytoma, AA-anaplastic astrocytoma, GBM-glioblastoma, E-ependymoma, M-medulloblastoma, R-atypical rhabdoid tumor, P-choroid plexus papilloma and AC1, AC3, AC4-adult control cerebellum and AC2, AC5, AC6, AC7-adult control frontal lobe. nd – not determinedBack to article page
