To investigate the functional role and mechanistic contribution of nucleophosmin (NPM1) in WNT-driven hyperproliferation and solid tumor initiation.
Evaluated NPM1 expression and functional necessity in mouse models of APC-loss-induced intestinal and hepatic tumorigenesis.
Assessed translation kinetics, ribosomal profiling, and cellular stress signaling pathways following NPM1 depletion.
Analyzed clinical human colorectal cancer genomic and transcriptomic datasets for associations between NPM1 levels, WNT activity, proliferation, and TP53 status.
NPM1 was upregulated following APC loss and was required to sustain WNT-driven intestinal and liver tumor formation.
Depletion of NPM1 induced ribosome pausing and accumulation at the 5'-end of coding transcripts, triggering a protein synthesis stress response and activating p53-mediated tumor suppression.
Elevated NPM1 expression correlated with heightened WNT signaling in human colorectal cancers, while NPM1-deleted tumors showed preferential co-inactivation of TP53.
