在模式生物中,饮食限制(DR)对寿命和健康寿命的许多影响与蛋白质和氨基酸(AA)摄入量减少以及特定营养信号通路的刺激有关。在酵母中的研究表明,培养基中添加丝氨酸、苏氨酸和缬氨酸通过激活不同但相互关联的途径促进细胞致敏和衰老。在啮齿动物模型中,蛋白质或必需氨基酸限制延长了寿命和健康期。在人类中,蛋白质限制(PR)与降低癌症,糖尿病和总体死亡率有关。因此,旨在降低蛋白质或特定氨基酸摄入量的干预措施可能是有益的,并有可能被广泛采用,并有效地优化健康寿命。
Many of the effects of dietary restriction (DR) on longevity and health span in model organisms have been linked to reduced protein and amino acid (AA) intake and the stimulation of specific nutrient signaling pathways. Studies in yeast have shown that addition of serine, threonine, and valine in media promotes cellular sensitization and aging by activating different but connected pathways. Protein or essential AA restriction extends both lifespan and healthspan in rodent models. In humans, protein restriction (PR) has been associated with reduced cancer, diabetes, and overall mortality. Thus, interventions aimed at lowering the intake of proteins or specific AAs can be beneficial and have the potential to be widely adopted and effective in optimizing healthspan.
