Of importance, depletion of PFKP in U251 (Supplementary Fig. 1e) and U87 human GBM cells that overexpressed constitutively active EGFRvIII mutant (U87/EGFRvIII) (Fig. 1e) revealed that a reduction in PFKP expression impaired glucose uptake, lactate production (Supplementary Fig. 1e and Fig. 1e), and cell proliferation (Supplementary Fig. 1f and Fig. 1f). This evidence concerns the gene PFKP and glioblastoma.
