The Hippo signaling pathway is one of the most frequently altered pathways in human cancer. Researchers at the National Cancer Institute (NCI) have developed a genetically encoded peptide inhibitor of the Hippo signaling pathway members YAP1/TAZ-TEAD, to dissect and study the specific TEAD-downstream regulatory gene expression networks of cell proliferation, tissue homeostasis, and stem cell functions in different cell types and pathologies. The DNA construct encoding this inhibitor may be delivered to cells using lentivirus, adenovirus, or adeno-associated virus, and is a valuable research tool. NCI seeks licensees for this peptide inhibitor and the encoding DNA construct.
