1002-胆管癌RAS-GTP抑制的抗肿瘤活性

这个研究探讨了RAS-GTP抑制剂在治疗带有KRAS突变的胆管癌（CCA）中的应用效果。研究表明，名为RMC-7977及daraxonrasib的药物通过精准打击激活状态的RAS蛋白，在临床前模型和人类患者中均展示了显著的抗肿瘤活性。RAS通路的过度激活被确定为产生耐药性的核心因素，其中涉及KRAS基因扩增和MYC超表达等分子机制。实验进一步证明，将此类抑制剂与化疗等标准疗法联合使用，能产生更强的协同治疗效益，并有效延长生存期。通过对免疫微环境的分析，研究为这一难治性恶性肿瘤制定了临床转化路线图。总之，该成果支持将RAS-GTP抑制作为未来胆管癌靶向治疗的核心方案。References:Entrialgo-Cadierno R, Morali K, Feliu I, et al.
