Gut microbiota-derived phenylacetylglutamine accelerates aging by driving cellular senescence through mitochondrial ...
衰老过程复杂而多样,不仅受到遗传因素的深刻影响,也与环境、生活方式以及体内的微观生态密切相关。近年来,研究人员发现,作为“第二基因组”的肠道微生物群,在宿主健康与衰老中扮演着不可或缺的角色。这些微生物群落不仅随着年龄发生动态变化,还通过代谢活动生成大 ...
Research has identified numerous well-known signaling pathways as being associated with senescence, including the Insulin/IGF-1 signaling (IIS) pathway, the mTOR pathway, the AMPK pathway, the NF-κB ...
近年来,以高脂肪、低碳水化合物为特点的生酮饮食(KD)在减肥和改善健康方面广受欢迎。生酮饮食通过极大减少碳水化合物的摄入,促使肝脏产生酮,这些酮能够作为替代能源供给身体。然而,尽管生酮饮食被推荐用于控制癫痫、改善神经退行性疾病症状,研究也逐渐显露出其潜在的副作用。 最新的研究文献《Science Advances》中的一项研究揭示了生酮饮食可能导致P53依赖性细胞衰老,影响多个器官,包括心脏和肾脏 ...
近年来,有关二甲双胍作用机制的研究层出不穷;其中腺苷酸活化蛋白激酶(AMPK)信号通路在二甲双胍的作用机制中扮演至关重要的角色。本期 ...
Additionally, GA promotes the AMPK-eNOS-FAS pathway, enhances Kip1/p27 and Cip1/p21 levels, and inhibits the expression of cyclin B1 and CDK1. Moreover, GA reduces hydroxyl radicals and alleviates ...
