FOLH1 and neoplasm: Next, we analysed PSMA (FOLH1) expression using the Ivy GAP RNA‐Seq data set (http://glioblastoma.alleninstitute.org/) that, in contrast to other cancer genome data sets, shows the individual gene expression profiles for the different anatomic structures, such as leading edge (LE), infiltrating tumour (IT), cellular tumour (CT), PM and cellular pseudopalisades (CP), which were isolated by using the laser microdissection.19
