摘要

Circadian disruption is a risk factor for metabolic,psychiatric and age-related disorders,and non-human primate models could help to develop therapeutic treatments.Here,we report the generation of BMAL1 knockout cynomolgus monkeys for circadian-related disorders by CRISPR/Cas9 editing of monkey embryos.These monkeys showed higher nocturnal locomotion and reduced sleep,which was further exacerbated by a constant light regimen.Physiological circadian disruption was reflected by the markedly dampened and arrhythmic blood hormonal levels.Furthermore,BMALl-deficient monkeys exhibited anxiety and depression,consistent with their stably elevated blood cortisol,and defective sensory processing in auditory oddball tests found in schizophrenia patients.Ablation of BMAL1 up-regulated transcriptional programs toward inflammatory and stress responses,with transcription networks associated with human sleep deprivation,major depressive disorders,and aging.Thus,BMAL1 knockout monkeys are potentially useful for studying the physiological consequences of circadian disturbance,and for developing therapies for circadian and psychiatric disorders.
