Abstract
Lung cancer is the leading cause of cancer deaths worldwide with non small-cell lung cancer (NSCLC) accounting for 80% of all lung cancers. Although activating mutations in genes of the RAS-MAPK pathway occur in up to 30% of all NSCLC, the cooperating genetic lesions that are required for lung cancer initiation and progression remain poorly understood. Here we identify a role for the cell polarity regulator Scribble (Scrib) in NSCLC. A survey of genomic databases reveals deregulation of SCRIB in human lung cancer and we show that Scrib+/− mutant mice develop lung cancer by 540 days with a penetrance of 43%. To model NSCLC development in vivo, we used the extensively characterized LSL-KRasG12D murine model of NSCLC. We show that loss of Scrib and activated oncogenic KRas cooperate in vivo, resulting in more aggressive lung tumors, likely due to a synergistic elevation in RAS–MAPK signaling. Finally, we provide data consistent with immune infiltration having an important role in the acceleration of tumorigenesis in KRasG12D lung tumors following Scrib loss.
