WWTR1 and cancer: Because Hippo-YAP1/WWTR1 signaling cascade is located at the crossroads of adhesion signaling, G-protein-coupled receptor (GPCR) signaling, receptor tyrosine kinase (RTK) signaling and stem cell biology (12,60–62), cancer genomics of the FAT signaling cascades could be applied for diagnostics, prognostics and therapeutics in the era of personalized medicine.
