Qki deficiency maintains stemness of glioma stem cells in suboptimal environment by downregulating endolysosomal degradation

Jian Hu and colleagues use mouse models to show that Qki deficiency promotes gliomagenesis by allowing neural stem cells to maintain their stemness outside the subventricular zone. Mechanistically, they show that Qki deficiency decreases endolysosome-mediated degradation of receptors that are essential for maintaining self-renewal, allowing cells to cope with low ligand levels outside of their niche.
