聚焦DNA损伤信号通路路:从关键试剂到仪器耗材的完整解决方案
2025-10-20 · 产品方案 · 百灵威授权转载
DNA损伤信号通路是细胞应对基因组损伤的核心防御系统,其通过精密调控网络实现损伤感知、信号转导与效应输出的动态连接。该通路的核心机制在于ATM/ATR等磷酸激酶作为核心感应器,可识别不同类型的DNA损伤(如双链断裂、复制压力),进而磷酸化激活下游关键效应蛋白(如Chk1/Chk2),最终通过调控细胞周期检查点、DNA修复机制和细胞凋亡三大通路维持基因组稳定性。这一多层次调控网络构成了经典的"损伤感知-信号转导-效应执行"范式。
DNA损伤信号通路作为基因组守护者的核心地位。该通路不仅通过阻止损伤DNA的复制与分裂维持细胞正常功能,更在肿瘤抑制、衰老调控和发育过程中发挥关键作用。其功能缺陷将直接导致基因组不稳定性增加,成为癌症发生的重要驱动因素。当前在新型损伤感知机制(如染色质环境对损伤信号的调控)、相分离在信号枢纽形成中的作用、代谢应激与DNA损伤的交叉对话,以及肿瘤免疫中DNA损伤响应的特殊机制等领域研究火热。对cGAS-STING通路在胞质DNA监测中作用的深入解析,更将DNA损伤响应与天然免疫建立了新颖连接。
该通路已成为癌症治疗的重要靶标,在精准医疗、基因毒性评估、抗癌药物筛选和放疗疗效监测、基因编辑等技术领域具有重要应用。
