1212-结直肠癌KRAS抑制剂耐药图谱

这篇文献综述探讨了大肠癌在接受KRAS G12C抑制剂治疗时产生耐药性的复杂机制。研究重点介绍了Alonso及其同事的发现，指出肿瘤通过基因突变和转录组适应（如上皮细胞状态切换和促炎通路激活）来逃避药物作用。通过空间转录组分析，科学家们观察到同一肿瘤内部存在高度的异质性，不同区域表现出截然不同的适应性程序。治疗过程中，肿瘤细胞会从最初的再生状态转变为干细胞或潘氏细胞表型，并最终形成持久的炎症环境。这种动态的细胞塑性不仅挑战了传统的单一活检诊断，还为开发结合免疫或抗炎通路的联合疗法提供了理论依据。总之，该研究强调了在精准医疗中整合空间组织信息和表型成像对于克服耐药性的重要性。References:White M, Campbell AD, Sansom OJ.
