SERPINE1 and glioblastoma: We performed Kaplan-Meier analysis of ZYX and SERPINE1 versus overall survival in a GBM patient dataset (http://www.betastasis.com/glioma/rembrandt/), noting that high expression of ZYX and SERPINE1 correlated with shorter survival of patients (P=2.05e-4 and P=0.02, Supplementary Figure 4A-4B).
