Cell cycle restriction by histone H2AX limits proliferation of adult neural stem cells Vrije Universiteit Brussel
Adult neural stem cell proliferation is dynamic and has the potential for massive self-renewal yet undergoes limited cell division in vivo. Here, we report an epigenetic mechanism regulating proliferation and self-renewal. The recruitment of the PI3K-related kinase signaling pathway and histone H2AX phosphorylation following GABA(A) receptor activation limits subventricular zone proliferation. As a result, NSC self-renewal and niche size is ...
