Macroautophagy/autophagy plays crucial roles in aging and the pathogenesis of age-related diseases. Studies in various animal models demonstrate the conserved requirement for autophagy-related genes in multiple anti-aging interventions. A recent study from the Shirasu-Hiza lab showed that a newly designed intermittent time-restricted feeding (iTRF) dietary regimen can robustly extend fly healthspan and lifespan through circadian rhythm-dependent activation of autophagy. The night-specific induction of autophagy is both necessary and sufficient for iTRF-mediated health benefits. The study provides the intriguing possibility that novel behavioral or pharmaceutical interventions that promote night-specific autophagy can be used to promote healthy aging.
自噬在衰老和与年龄相关疾病的发病机制中起着至关重要的作用。在各种动物模型中的研究表明,自噬相关基因在多种抗衰老干预措施中具有保守的需求。Shirasu-Hiza 实验室的一项最新研究表明,一种新设计的间歇性限时喂养(iTRF)饮食方案可以通过昼夜节律依赖性自噬的激活,强有力地延长果蝇的健康寿命和寿命。自噬的夜间特异性诱导对于 iTRF 介导的健康益处是必要且充分的。该研究提出了一种有趣的可能性,即促进夜间特异性自噬的新型行为或药物干预措施可用于促进健康衰老。
