DKK1 and glioblastoma: We have identified 98 DEGs for glioblastoma using GSEA (see Figure 4) out of which 17 are actively crosstalking between enriched pathways, namely DKK1, MEGF9, S100P, CEACAM6, DAB2, SLPI, PIK3CB, PKIA, TENT5C, KIAA0513, CAPN2, SDCBP, NME4, RAB5BC, SLC6A6, ENO2, and GUCY1B1, which are quite evident in Figure 5.
