373-MetroSCREEN:单细胞代谢图谱与调控推断框架

from 聊聊Sci

这项研究介绍了一套名为 MetroSCREEN 的创新计算框架,旨在通过单细胞转录组数据系统地推断细胞代谢状态及其上游调控机制。该工具突破了现有技术在空间分辨率和多组学同步测量上的局限,能够整合细胞内在遗传因子(如转录调节因子)与外在环境信号(如细胞因子互动),从而精准预测代谢重编程的关键驱动力。研究者利用该框架构建了 MetroTIME 数据库,深入解析了肿瘤微环境中成纤维细胞与巨噬细胞在代谢上的异质性,揭示了不同代谢亚型如何影响免疫抑制及肿瘤进展。通过对多项癌症临床数据的分析,该研究证实了代谢模块评分与患者生存率及免疫治疗反应之间存在显著关联。此外,该工具还为药物重定向提供了新思路,通过识别特定代谢通路的调节因子,助力开发针对肿瘤代谢的新型个性化治疗策略。References: Tang K, Han Y, Sun D, et al.
