چکیده

The transcriptional co-activators YAP and TAZ are key regulators of organ size and tissue homeostasis, and their dysregulation contributes to human cancer. Here, we discover YAP/TAZ as bona fide downstream effectors of the alternative Wnt signaling pathway. Wnt5a/b and Wnt3a induce YAP/TAZ activation independent of canonical Wnt/β-catenin signaling. Mechanistically, we delineate the "alternative Wnt-YAP/TAZ signaling axis" that consists of Wnt-FZD/ROR-Gα12/13-Rho GTPases-Lats1/2 to promote YAP/TAZ activation and TEAD-mediated transcription. YAP/TAZ mediate the biological functions of alternative Wnt signaling, including gene expression, osteogenic differentiation, cell migration, and antagonism of Wnt/β-catenin signaling. Together, our work establishes YAP/TAZ as critical mediators of alternative Wnt signaling.

YAP/TAZ Incorporation in the β-Catenin Destruction Complex Orchestrates the Wnt Response

The Hippo transducers YAP/TAZ have been shown to play positive, as well as negative, roles in Wnt signaling, but the underlying mechanisms remain unclear. Here, we provide biochemical, functional, and genetic evidence that YAP and TAZ are integral components of the β-catenin destruction complex that serves as cytoplasmic sink for YAP/TAZ. In Wnt-ON cells, YAP/TAZ are physically dislodged from t...

YAP/TAZ Join the Play with β-catenin to Orchestrate Wnt Signaling

For the purpose of studying Wnt signaling, the intestinal epithelium has been the most relevant biological tissue for its differential topology expression of Wnt signaling: active in all crypt cells (helping in proliferation, stemness, regeneration, and tissue homeostasis) and inactive in the villi cells. Interestingly though, YAP/TAZ regulation through Wnt signaling has been more controversial...

Interacting network of Hippo, Wnt/β-catenin and Notch signaling represses liver tumor formation

Acquiring a selective growth advantage by breaking the proliferation barrier established by gatekeeper genes is a centrally important event in tumor formation. Removal of the mammalian Hippo kinase Mst1 and Mst2 in hepatocytes leads to rapid hepatocellular carcinoma (HCC) formation, indicating that the Hippo signaling pathway is a critical gatekeeper that restrains abnormal growth in hepatocyte...

TIAM1 Antagonizes TAZ/YAP Both in the Destruction Complex in the Cytoplasm and in the Nucleus to Inhibit Invasion of Intestinal Epithelial Cells

Aberrant WNT signaling drives colorectal cancer (CRC). Here, we identify TIAM1 as a critical antagonist of CRC progression through inhibiting TAZ and YAP, effectors of WNT signaling. We demonstrate that TIAM1 shuttles between the cytoplasm and nucleus antagonizing TAZ/YAP by distinct mechanisms in the two compartments. In the cytoplasm, TIAM1 localizes to the destruction complex and promotes TA...
