We used microarrays to analyse a cohort of CNS PNETs and medulloblastomas to identify gene expression related to tumor subgroups. RNA extracted from 23 frozen tumor samples, plus a commercial fetal brain sample, was analysed using Affymetrix U133 plus 2.0 arrays. Tumour subgroups, based on gene expression, were identified using clustering methods.http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-19404http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-19404/samples/
