衰老与多种分子过程有关,如氧化损伤、免疫活性降低或表观遗传异常、突变和炎症增加。这些过程中的许多都与营养感应信号通路有关,这表明饮食在衰老过程中发挥着关键作用。事实上,饮食中的蛋白质含量可以同时影响寿命和繁殖力,但往往是相反的。在许多孤立的生物体中,富含蛋白质的饮食极大地缩短了寿命,但增加了产卵量。本研究以皱纹盘尾蚂蚁为研究对象,研究了饲料中蛋白质与碳水化合物的比例对有生育能力的工蚁成活率和繁殖力的影响。我们以中等碳水化合物或高蛋白饲料(分别为1:2和2:1)喂养蜂群,并在9周内监测工人的存活和产蛋量。富含蛋白质的饮食没有改变工蚁产卵的能力,但降低了工蚁的存活率,这表明大量摄入蛋白质可能会缩短有生育能力的蚂蚁工蚁的寿命,而不会促进繁殖。我们的研究首次表明,富含蛋白质的饮食会降低有生育能力的员工的整体健康水平。
Aging is associated with diverse molecular processes such as oxidative damage, decrease in immunocompetence, or increase in epigenetic abnormalities, mutations, and inflammations. Many of these processes are linked to nutrient-sensing signalling pathways, suggesting that diet plays a critical role in the aging process. In fact, the protein content in the diet can affect both longevity and fecundity, but often in opposite directions. In many solitary organisms, protein-rich diets dramatically shorten lifespan, but increase egg production. We used the ant Temnothorax rugatulus to investigate the effect of the protein to carbohydrate ratio in the diet on the survival and fecundity of fertile workers. We fed colonies either a moderately high-carbohydrate or high-protein diet (1:2 and 2:1 respectively) and monitored worker survival and egg production over 9 weeks. The protein-rich diet did not alter the ability of workers to lay eggs, but reduced worker survival, suggesting that consuming large amounts of protein may shorten lifespan in fertile ant workers without promoting reproduction. Our study shows for the first time that a protein-rich diet reduces the overall fitness of fertile workers.
