MTOR is a central regulator of metabolism and cell growth in pancreatic cancer. Despite its critical role, cells can escape from MTOR inhibition by adaptive rewiring of oncogenic signaling. In this study, upregulation of MYC-driven pathways was identified as a possible factor conferring resistance to MTOR inhibition. Epigenetic BET-inhibitiors that indirectly target MYC were utilized and shown to work synergistically with MTOR inhibitors in PDAC cells, thus indicating the potential of MTOR/BET inhibitor combination therapies to overcome secondary resistance mechanisms in pancreatic cancer.
