研究问题

Aging is associated with a progressive loss of proteostasis and increased susceptibility to neurodegenerative and metabolic disorders.

方法

In this Review, we discuss the emerging role of protein persulfidation as a central regulator of proteostasis during aging and age-related disorders.;In this study, structural modeling further suggested that persulfidation induces subtle conformational changes that favor substrate binding and catalytic efficiency, providing a direct molecular mechanism by which H2S regulates metabolic enzyme activity.

核心结论

In mammalian cells, endogenous H2S is primarily synthesized by cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE), and the coupled cysteine aminotransferase (CAT)/3-mercaptopyruvate sulfurtransferase (3-MST, MPST) pathway, although the relative contribution of each pathway varies among tissues and physiological conditions [10,11,12,13].;Approximately 40% of detected persulfidated proteins exhibited significant age-dependent changes, with the predominant trend corresponding to a global decline in persulfidation. ‖ 结论:In this review, we discuss emerging evidence linking loss of persulfidation to protein aggregation, biomolecular condensates, and age-related functional decline, and highlight therapeutic strategies aimed at restoring persulfidation as a promising avenue for healthy aging and disease intervention.

局限

全文未设独立 limitations 节;结构上为综述/二次研究,因果推断强度受限。

对本项目的价值

★★★★☆ 脑老化是最大未满足需求,也是终点最难量化的领域;biomarker 与认知读数选择最敏感。命中核心 NAD⁺轴;设计 多组学。
