1Spaceflight decelerates the epigenetic clock orchestrated with a global alteration in DNA methylome and transcriptome in the mouse retina显示文摘Astronauts exhibit an assortment of clinical abnormalities in their eyes during long-duration spaceflight.The purpose of this studywas to determinewhether spaceflight induces epigenomic and transcriptomic reprogramming in the retina or alters the epigenetic clock.The mice were flown for 37 days in animal enclosure modules on the International Space Station;ground-based control animals weremaintained under similar housing conditions.Mouse retinas were isolated and both DNA methylome and transcriptome were determined by deep sequencing.We found that a large number of genes were differentially methylated with spaceflight,whereas there were fewer differentially expressed genes at the transcriptome level.Several biological pathways involved in retinal diseases such as macular degeneration were significantly altered.Our results indicated that spaceflight decelerated the retinal epigenetic clock.This study demonstrates that spaceflight impacts the retina at the epigenomic and transcriptomic levels,and such changes could be involved in the etiology of eye-related disorders among astronauts.Zhong Chen Seta Stanbouly Nina CNishiyama Xin Chen Michael D.Delp Hongyu Qiu Xiao WMao Charles Wang 2021Precision Clinical Medicine2021,4,2:1
