摘要:
端粒重复序列RNA(TERRA)是调控端粒稳态的关键长链非编码RNA,其通过动态调控端粒异染色质组装、DNA损伤应答(DDR)及同源重组修复(HR),在维持基因组稳定性中发挥核心作用。尤其在端粒酶阴性癌细胞中,TERRA通过招募重组酶(如RAD51)和调控R-loop动态平衡,驱动替代性端粒延长(ALT)机制。近年来的研究表明,TERRA所展现出来的相分离特性和m6A甲基化修饰可以直接影响ALT过程的有效性,不过其背后的分子交互网络仍需进一步探索。本文旨在全面回顾TERRA的功能调节及其在ALT中的作用机制,深入剖析两者之间的相互作用,并对未来的研究方向提出展望,同时讨论以TERRA为靶点进行临床转化的可能性,旨在为针对ALT阳性肿瘤设计特定治疗方案提供新的思路,也为发展更有效的抗癌策略奠定理论基础。
