ELAVL2 and glioblastoma: To further examine the possible involvement of ELAVL2 in the MES transition, we performed GSEA on other public GBM mRNA expression datasets (GSE16011 & GSE53733) obtained from GEO database using 3 distinct MES-related gene sets - HM_EMT, TCGA_GBM_Mesenchymal (2010), and GI_Mesenchymal (2017).
