Abstract Accumulation of DNA damage, particularly oxidative DNA damage, is a major molecular driver of senescence and aging. The enzyme apurinic/apyrimidinic endonuclease-1 (Apex1) is essential for base-excision repair, but its role in protecting the brain from age-related deterioration remains unclear. Here we show that conditional knockout (cKO) of Apex1 in forebrain neurons causes early and progressive cognitive impairment in mice.
