Our analysis shows that SRPX and SRPX2 differ in expression between the mesenchymal subset and the rest of glioblastoma samples (subsets as defined by Phillips et al.[60], fold changes 1.7 and 2.4, respectively, t-test p-values 5.5E-4 and 1.5E-7, respectively). Here, SRPX is linked to glioblastoma.
