An allosteric pan-TEAD inhibitor blocks oncogenic YAP/TAZ signaling and overcomes KRAS G12C inhibitor resistance

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.

An allosteric pan-TEAD inhibitor blocks oncogenic YAP/TAZ signaling and overcomes KRAS G12C inhibitor resistance.

Project description:The Hippo pathway is a key growth control pathway that is conserved across species. The downstream effectors of the Hippo pathway, YAP (Yes-associated protein) and TAZ (transcriptional coactivator with PDZ-binding motif), are frequently activated in cancers to drive proliferation and survival. Based on the premise that sustained interactions between YAP/TAZ and TEADs (transcriptional enhanced associate domain) 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 human TEAD paralogs 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 achieves strong antitumor efficacy in vivo. Furthermore, we uncovered that GNE-7883 effectively overcomes both intrinsic and acquired resistance to KRAS (Kirsten rat sarcoma viral oncogene homolog) G12C inhibitors in diverse preclinical models through the inhibition of YAP/TAZ activation. Taken together, this work demonstrates the activities of TEAD SMIs in YAP/TAZ-dependent cancers and highlights their potential broad applications in precision oncology and therapy resistance.

Genome-Wide CRISPR Screen Identifies Multiple Synthetic Lethal Targets That Enhance KRAS (G12C) Inhibitor Efficacy [scRNA-seq]

Project description:KRAS G12C inhibitors (G12Ci) alone and in various combinations are being tested in multiple tumors with over-activation of the RAS/ERK pathway. KRAS plays a critical role in normal cell signaling; hence, G12Cis could influence the signaling pathways. We found that several novel pathways including Hippo pathways are upregulated upon MRTX849 treatment. Our results argue for testing KRAS G12C and TEAD inhibitor combinations in NSCLC patients.

Genome-Wide CRISPR Screen Identifies Multiple Synthetic Lethal Targets That Enhance KRAS (G12C) Inhibitor Efficacy [CRISPR]

Project description:KRAS G12C inhibitors (G12Ci) alone and in various combinations are being tested in multiple tumors with over-activation of the RAS/ERK pathway. KRAS plays a critical role in normal cell signaling; hence, G12Cis has been reported to create resistance. We found several novel pathways, including Hippo pathways, are enriched from significant dropouts upon MRTX849 treatment. Our results argue for testing KRAS G12C and TEAD inhibitor combinations in NSCLC patients.
