Outline of Final Research Achievements |
In this project, we tried to analyze the mechanisms of EGFR-TKI and ALK-TKI resistance and to develop overcoming drugs. We performed the following experiments and obtained several new findings. (1) We searched the EGFR binding protein and found that Aki1, a scaffold protein, interacted with EGFR and mediated EGFR-TKI resistance. We could not find out the positive relationship between Pim kinase expression and EGFR-TKI resistance. During the analysis of c-met signaling pathway for EGFR-TKI resistance, we found that a c-met inhibitor tivantinib, exhibited anti-tumor activity by inhibiting tubulin polymerization. (2) Using patient-derived samples, we succeeded to identify several mutations that were associated with ALK-TKI resistance. Theese resistance could be overcame the second generation ALK-TKIs, such as alectinib and ceritinib.
