Abstract

Intestinal homeostasis is tightly regulated by complex yet poorly understood signaling networks. Here, we demonstrate that Lats1/2, the core Hippo kinases, are essential to maintain Wnt pathway activity and intestinal stem cells. Lats1/2 deletion leads to loss of intestinal stem cells but drives Wnt-uncoupled crypt expansion. To explore the function of downstream transcriptional enhanced associate domain (TEAD) transcription factors, we identified a selective small-molecule reversible inhibitor of TEAD auto-palmitoylation that directly occupies its lipid-binding site and inhibits TEAD-mediated transcription in vivo. Combining this chemical tool with genetic and proteomics approaches, we show that intestinal Wnt inhibition by Lats deletion is Yes-associated protein (YAP)/transcriptional activator with PDZ-binding domain (TAZ) dependent but TEAD independent. Mechanistically, nuclear YAP/TAZ interact with Groucho/Transducin-Like Enhancer of Split (TLE) to block Wnt/T-cell factor (TCF)-mediated transcription, and dual inhibition of TEAD and Lats suppresses Wnt-uncoupled Myc upregulation and epithelial over-proliferation in Adenomatous polyposis coli (APC)-mutated intestine. Our studies highlight a pharmacological approach to inhibit TEAD palmitoylation and have important implications for targeting Wnt and Hippo signaling in human malignancies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
