The present invention relates to a method of treatment and method of therapy selection for patient suffering from cancer. The inventors provide the first demonstration of a dual role of IRE1 downstream signaling in cancer. Indeed, the inventors demonstrate that the modulation of IRE1 signaling characteristics in GBM cells controls tumor aggressiveness. Furthermore, the inventors provide evidence supporting a novel concept where IRE-downstream signals play combined/integrated roles in cancer development, where XBP1s provides pro-tumoral signals, whereas RIDD of mRNA and miR17 rather elicits anti-tumoral features. Their data, obtained using established cell lines, patient tumor samples and primary GBM lines, depict a complex scenario where IRE1 signaling orchestrates distinct aspects of GBM biology. In particular, the invention relates to a method for predicting whether a subject will be eligible to a treatment with an IRE1 RNase inhibitor.
本发明涉及癌症患者的治疗方法和疗法选择方法。本发明者首次证明了 IRE1 下游信号在癌症中的双重作用。事实上,本发明人证明了对 GBM 细胞中 IRE1 信号特征的调节可控制肿瘤的侵袭性。此外,发明人还提供了支持一种新概念的证据,即 IRE 下游信号在癌症发展中发挥联合/整合作用,其中 XBP1s 提供了促肿瘤信号,而 mRNA 的 RIDD 和 miR17 则激发了抗肿瘤特征。他们利用已建立的
细胞系、患者肿瘤样本和原发性 GBM 系获得的数据,描述了 IRE1 信号协调 GBM
生物学不同方面的复杂情况。具体而言,本发明涉及一种预测受试者是否适合接受 IRE1 RNase
抑制剂治疗的方法。
