The MTORL1433S mutation was oncogenic in Ba/F3 models and showed resistance to osimertinib...in NCI-H1975 cells harboring the MTORL1433S mutation...Osimertinib in combination with mTOR inhibitors abrogated acquired resistance to osimertinib....MTORL1433S- and EGFRL858R/T790M-mutant NSCLC cells were sensitive to osimertinib plus mTOR inhibitors.
