Project description:Purpose: The goal of this study is to understand the signaling pathway alteration in NCI-H226 cells treated with new TEAD autopalmitoylation inhibitor TM2, and to further validate TEAD inhibitor for specifity in TEAD-YAP interuption. Methods: Mesothelioma cell line NCI-H226 was chosen to be treated with TEAD palmitoylation inhibitor TM2 at 1μM for 24 hours. Total RNA was isolated for the analysis. RNA samples were sent to Novogen for library construction, RNA sequencing and raw data process. Conclusions: Our study privides gene expression profiling evidence to validate our TEAD palmitoylation inhibitor TM2 as specific small molecule to block TEAD transcriptional activity in mesothelioma cells.

Project description:We investigate the dependence of human malignant mesothelioma on functional TEAD transcription factors to maintain fully established tumors in vivo. We show that TEAD inhibitor K-975 stops tumor growth in vivo, eventually causing tumor regression, by downregulating TEAD activity and altering, thus, TEAD-dependent transcription in a dysfunctional Hippo genetic background. Our data validate the concept of inhibiting an activated YAP1/TEAD complex for the treatment of malignant pleural mesothelioma patients.
Project description:The Hippo pathway is a key growth-control pathway conserved across species. The downstream effectors of the Hippo pathway YAP/TAZ are frequently activated in cancer cells by a diverse array of mechanisms to drive proliferation and survival. Based on the premise that sustained interactions between YAP/TAZ and TEADs are central to their transcriptional activities, we discovered a potent small molecule inhibitor (SMI) GNE-7883 that allosterically blocks the interactions between YAP/TAZ and all four TEAD paralogs in human cells through binding to the TEAD lipid pocket. GNE-7883 effectively reduces chromatin accessibility specifically at TEAD motifs, suppresses cell proliferation in a variety of cell line models, and achieved strong anti-tumor efficacy in vivo. Furthermore, we uncovered that GNE-7883 effectively overcomes resistance to the recently approved KRAS G12C inhibitor sotorasib in both treatment-refractory and acquired resistance cell line models, providing strong proof-of-concept of TEAD SMIs in targeting YAP/TAZ-mediated KRAS inhibitor resistance. Taken together, this work demonstrates activities of TEAD SMIs in YAP/TAZ-dependent cancers and highlights their potential broad applications in precision oncology and therapy resistance.
