    Paradoxical Role of β8 Integrin on Angiogenesis and Vasculogenic Mimicry in Glioblastoma

    Co-culture assays followed by Cell Counting Kit-8, migration, Matrigel tube formation, and sprouting assays were conducted to assess the proliferative, migratory, and angiogenic capacity of glioblastoma multiforme cells and human brain microvascular endothelial cells.

    Induction of Synapse Formation by De Novo Neurotransmitter Synthesis

    Researchers reported that in both stem cell-derived human neurons as well as in vivo mouse neurons of purely glutamatergic identity, ectopic expression of GABA-synthesis enzymes and vesicular transporters were sufficient to both produce GABA from ambient glutamate and transmit it from presynaptic terminals.

    PDGF Signaling Inhibits Mitophagy in Glioblastoma Stem Cells Through N6-Methyladenosine

    The authors reported that pharmacologic targeting of methyltransferase-like 3 augmented anti-tumor efficacy of platelet-derived growth factor receptor (PDGF) and mitophagy inhibitors in vitro and in vivo.

    AbstractGraphical Abstract

    Glioblastoma-Associated Microglia-Derived Exosomal circKIF18A Promotes Angiogenesis by Targeting FOXC2

    Glioblastoma-associated microglia M2 polarization was constructed, and microglia-derived exosomes were isolated to co-culture with human brain microvessel endothelial cells.

    Abstract

    A Predictive Microfluidic Model of Human Glioblastoma to Assess Trafficking of Blood–Brain Barrier-Penetrant Nanoparticles

    Researchers presented a microfluidic model of vascularized glioblastoma featuring a tumor spheroid in direct contact with self-assembled vascular networks comprising human endothelial cells, astrocytes, and pericytes.
