    الوصف: Glioblastoma (GBM) is the most deadJy type of malignant brain tumor, despite extensive molecular ana y ses of GBM cens. ln recent years, the tumor microenvirc;inment (TME} has been ,recognized as an important player and therapeutic target ln GBM. However, there is a need for a full and Integrated understanding of the different cellular and molecular components involved in the GBM TME and their interactions for the development of more efficient therapies. ln this review, we provide a comprehensive report of the GBM TME, which assembles the contributions of physicians and translational researchers working on brain tumor pathology and ttierapy in France. We propose a holistic view of the subject by delineating the specifio features of the GBM TME at the cellular, molecul·ar, and therapeutic levels.

    الوصف: Glioma stem cells are highly resistant to cell death and as such are supposed to contribute to tumor recurrence by eluding anticancer treatments. Here, we show that spheroids that contain rat neural stem cells (NSCs) or rat glioma stem cells (cancer stem cells, CSCs) express isoforms 1 and 2 of pyruvate kinase (PKM1 and PKM2); however, the expression of PKM2 is considerably higher in glioma spheroids. Silencing of PKM2 enhances both apoptosis and differentiation of rat and human glioma spheroids. We establish that PKM2 was implicated in glioma spheroid differentiation through its interaction with Oct4, a major regulator of self-renewal and differentiation in stem cells. The small molecule Dichloroacetate (DCA), a pyruvate dehydrogenase kinase inhibitor, increases the amount of PKM2/Oct4 complexes and thus inhibited Oct4-dependent gene expression. Taken together, our results highlight a new molecular pathway through which PKM2 can manage gliomagenesis via the control of glioma stemness by Oct4.
