302-癌前衰老:双重机制与靶向干预

from 聊聊Sci

这篇评论探讨了癌前病变组织中细胞衰老的复杂作用,指出它既是最初的肿瘤抑制屏障,也会转变为促进肿瘤发展的因素。这种向有害状态的转变,主要是通过衰老相关分泌表型(SASP)驱动的,该表型持续重塑局部癌前组织微环境(PreTME),从而有利于肿瘤发生。作者们超越了传统的以细胞上皮为中心的视角,深入探讨了间质成纤维细胞和免疫细胞中的衰老如何一致地展现促肿瘤的破坏性效应。为阻止恶性进展,文章讨论了精确干预策略,包括清除衰老细胞的药物(衰老溶解剂)或调节SASP的药物(衰老拟态剂),以及饮食和运动等生活方式干预。领域面临的关键挑战是缺乏可靠且特异性的生物标志物,这阻碍了区分有益和有害衰老细胞的能力,从而影响了临床转化。References: Hoi X P, Stangis M M, Glass S E, et al.
