1412-内皮细胞来源的IGFBP5通过ITGB3/PI3K/AKT轴驱动结直肠癌血管浸润与肝转移

from 聊聊Sci

这项研究揭示了内皮细胞衍生的 IGFBP5 在驱动结直肠癌血管侵袭及肝转移中的关键作用。通过单细胞测序分析,研究人员发现一类高表达 IGFBP5 的尖端内皮细胞在转移组织中显著富集,且其表达水平与患者的预后不良密切相关。实验证实,内皮细胞分泌的 IGFBP5 能够与肿瘤细胞表面的受体 ITGB3 直接结合,通过激活 PI3K/AKT 信号通路增强癌细胞的增殖、迁移和黏附能力。此外,该轴心作用还会破坏血管屏障,为肿瘤细胞进入循环系统并发生远端转移创造条件。这一发现不仅阐明了肿瘤微环境中细胞间通讯的新机制,也为抑制结直肠癌转移提供了潜在的治疗靶点。References:Maimaitiming N, Deng Y, Liu H, et al.
