肿瘤抗药性的来龙去脉
发表在《科学-转化医学》(Science Translational Medicine)上的最新研究发现,胰腺导管腺癌(PDAC)的耐药性是肿瘤内在因素和肿瘤外在因素相互作用的结果。这些发现为针对致癌信号和肿瘤微环境的联合疗法提供了理论依据,以克服 PDAC 的耐药性。然而,患者会迅速产生耐药性,部分原因是受体酪氨酸激酶家族成员的上调。研究人员发现,在几种PDAC小鼠模型中,RAS-MAPK抑制剂与非受体酪氨酸激酶--局灶粘附激酶(FAK)抑制剂联合使用,比单独使用其中一种疗法更能减少肿瘤生长,提高存活率。单细胞RNA测序和细胞培养实验显示,肿瘤微环境中的癌症相关成纤维细胞被FAK激活,并影响PDAC细胞中RAS-MAPK抑制剂对MYC的下调,从而导致耐药性。"作者格雷戈里-比蒂解释说:"这确定了癌症相关成纤维细胞是克服RAS通路耐药性的新型治疗靶点。
