Patent number: 11525165Abstract: 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.Type: GrantFiled: December 19, 2018Date of Patent: December 13, 2022Assignees: INSERM, UNIVERSITÉ DE RENNES 1, ENIOS APPLICATIONS PRIVATE LIMITED COMPANYInventors: Eric Chevet, Aristotelis Chatziioannou
