Neurons migrating in developing brain cortices sustain DNA double-strand breaks that are repaired by non-homologous end-joining
A Nature study finds that neurons migrating through narrow spaces in the developing cerebral and cerebellar cortices sustain extensive DNA double-stranded breaks from mechanical stress. The damage is repaired without cell death, but impaired repair leads to later motor deficits i…
