Many cancers harbor oncogenic mutations of KRAS . Effectors mediating cancer progression, invasion, and metastasis in KRAS- mutated cancers are only incompletely understood. Here we identify cancer cell-ex- pressed murine TRAIL-R, whose main function ascribed so far has been the induction of apoptosis as a crucial mediator of KRAS-driven cancer progression, invasion, and metastasis and in vivo Rac-1 activation. Cancer cell-restricted genetic ablation of murine TRAIL-R in autochthonous KRAS-driven models of non- small-cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma (PDAC) reduces tumor growth, blunts metastasis, and prolongs survival by inhibiting cancer cell-autonomous migration, proliferation, and inva- sion. Consistent with this, high TRAIL-R2 expression correlates with invasion of human PDAC into lymph ves- sels and with shortened metastasis-free survival of KRAS- mutated colorectal cancer patients.
