Fig. 4From: Molecular analysis of pediatric brain tumors identifies microRNAs in pilocytic astrocytomas that target the MAPK and NF-κB pathwaysExpression of microRNAs and genes involved in senescence in pilocytic astrocytomas. (a) Illumina MicroRNA Expression array (MI-v2) data showing miR-146a and miR-155 are up-regulated in the majority of pilocytic astrocytomas and (b) Illumina HumanHT-12_v3 expression array data showing a higher level of expression for CDKN2A, IGFBP7 and TIMP1 in pilocytic astrocytomas compared to normal brain controlsBack to article page
