1441-乳酸化修饰:癌症代谢-表观遗传开关与治疗启示

from 聊聊Sci

这份综述文章详尽阐述了乳酸化修饰(Lactylation)在癌症治疗耐药中的核心作用。作者将这种代谢衍生出的蛋白质后修饰描述为一种“代谢-表观遗传开关”,它能将肿瘤微环境中的乳酸信号转化为稳定的促癌程序。文章深入解析了乳酸化通过酶促与非酶促途径建立的分子机制,并重点讨论了其如何增强肿瘤细胞的内在修复能力(如DNA修复)及外在免疫逃逸。通过识别特定的乳酸化位点与识别蛋白,研究揭示了该网络在维持癌症干性和抵御铁死亡等方面的关键功能。最后,文章提出了针对该轴心的多种临床转化策略,旨在通过代谢干预或位点特异性抑制来重新激活治疗敏感性。References:Yang C, Yang R, Zheng B, et al.
