Oncogenic Mutant P53 Sensitizes Non-Small Cell Lung Cancer Cells to Proteasome Inhibition Via Oxidative Stress-Dependent Induction of Mitochondrial Apoptosis

Abstract

NSCLC is the leading cause of cancer death due, in part, to a lack of active therapies in advanced disease. We demonstrate that combination therapy with a proteasome inhibitor, BH3-mimetic, and chemotherapy is an active precision therapy in NSCLC cells and tumors expressing Onc-p53 alleles.
