Abstract

Abstract The discovery of cancer cells' dependency on the self-cannibalization program autophagy has spawned the investigation of its efficacy as a therapeutic target. However, the use of lysomotropic agents to inhibit autophagy as single-agent therapeutics has proven less than optimal. Recent investigations into the design of sequential treatment strategies targeting pathways preferentially used by cancer cells have shown promise. This novel spin on personalized medicine seeks to exploit the kinetics and mechanisms by which cancer cells become dependent on proliferation and survival pathways. Oncogenic KRAS-driven non-small cell lung cancer (NSCLC) is known to depend on mTORC1-driven growth and autophagy for survival; such autophagy addiction is beneficial to cancer cells, as it eliminates the need for exogenous nutrient supplies. We aim to elucidate the mechanism and kinetics of autophagy addiction in NSCLC, in order to design sequential treatment strategies against this disease. Citation Format: Abigail R.
