Understanding the link between sleep deprivation and oxidative stress

项目摘要 我们发现睡眠不足会导致自由基（活性氧）的积累 物种，ROS）和氧化应激的肠道中的苍蝇和小鼠。这在很大程度上是因为 睡眠不足导致的过早死亡在这里，我们建议研究发生了什么 ROS积累的上游和下游。具体来说，我们会问睡眠不足是如何 导致ROS增加，以及ROS如何导致生物体死亡。一起，这将带来 我们更接近于完全理解睡眠对健康和长寿的作用。这是一个重要 我们中的许多人长期睡眠不足，睡眠不足会导致或 加剧了一系列疾病

Project Summary We discovered that sleep deprivation causes accumulation of free radicals (reactive oxygen species, ROS) and oxidative stress in the gut of flies and mice. This is in large part responsible for the premature death seen when sleep is very low. Here we propose to study what occurs upstream and downstream of ROS accumulation. Specifically, we will ask how the lack of sleep leads to increase in ROS, and how ROS then causes organismal death. Together, this will bring us closer to fully understanding what sleep does for health and longevity. This is an important problem as so many of us are chronically sleep deprived, and sleep deprivation causes or exacerbates a whole slew of diseases.
