We investigated the effects of a water extract of natto on the aging of the nematode Caenorhabditis elegans. The water extract significantly prolonged the adult lifespan of the wild-type worms and rendered them resistant to oxidative and thermal stress. In addition, treatment with natto extract significantly delayed the accumulation of lipofuscin, a characteristic of aging cells. Our findings suggest that components of natto have a beneficial anti-aging effect in vivo.
我们研究了纳豆水提取物对线虫秀丽隐杆线虫衰老的影响。该水提取物显著延长了野生型线虫的成虫寿命,并使其对氧化应激和热应激具有抗性。此外,用纳豆提取物处理显著延迟了脂褐素的积累,脂褐素是衰老细胞的一个特征。我们的研究结果表明,纳豆成分在体内具有有益的抗衰老作用。
