highly expressed in glioblastoma stem-like cells compared with normal brain and neural stem cells. Knockdown of isoform E-NPP1 in cultured glioblastoma stem-like cells results in an overall downregulation of stem cell-associated genes, induction of differentiation into astrocytic cell lineage, impairment of sphere formation, in addition to increased cell death, accumulation of cells in G1/G0 cell cycle phase and sensitisation to chemotherapeutic treatment. Knockdown of E-NPP1 affects purine and pyrimidine metabolism. E-NPP1, by acting upstream of E2F1, is indispensable for the maintenance of glioblastoma stem-like cells in vitro and hence required to keep glioblastoma stem-like cells in an undifferentiated, proliferative state
