Multiple cancer signalling networks take part in regulatory crosstalks with the Hippo tumour suppressor pathway through the transcriptional cofactor Yes-associated protein (YAP). Nevertheless, how YAP is controlled by pathway crosstalks in tumourigenesis remains poorly understood. Here, we performed a targeted kinase inhibitor screen in human cancer cells to identify novel Hippo pathway regulators. Notably, we identified the nerve growth factor (NGF) receptor tyrosine kinase (NTRK1), a molecule not previously associated with Hippo signalling. NTRK1 inhibition decreased YAP-driven transcription, cancer cell proliferation and migration. Furthermore, using a complementary functional genomics approach and mouse xenograft models, we show that NTRK1 regulates YAP oncogenic activity in vivo. Mechanistically, NTRK1 inhibition was found to induce large suppressor kinase 1 (LATS1) phosphorylation and to control YAP subcellular localization. Taken together, these results provide compelling evidence of crosstalks between the NGF-NTRK1 and Hippo cancer pathways.
