Title of Project: 51LS – New strategy to treat mutant p53-expressing cancers
Mutations in the p53 gene are present in more than half of all human cancers. The majority of these genetic alterations change the p53 tumor suppressor into a driver of malignant transformation. This so-called gain-of-function (GOF) activity is dependent on the molecular interaction of mutant p53 and other proteins. A thorough understanding of the proteins that bind to p53 mutants, as well as the pathways along which p53 mutations exert the oncogenic function, would assist the development of truly effective treatments. Here, we provide exciting evidence for the existence of a novel mutant p53 transcriptional complex which can directly activate the c-MET oncogene in multiple cancer cells. Our overarching goal is to generate direct evidence for using clinically applicable c-MET inhibitors as a therapeutic option for different forms of cancer expressing p53 mutants. To this end, we will (1) screen a panel of cancer cell lines for the presence of mutant p53/c-MET signaling and (2) examine the effectiveness of c-MET inhibition in cell culture assays. We respect the fact that mutant p53 acts upstream of the c-MET pathway and maintains its activity upon c-MET inhibition to compromise the drug sensitivity. In this regard, we have discovered a dramatic synergistic effect between c-MET and histone deacetylase (HDAC) inhibitors in mutant p53-expressing synovial sarcoma cells, and will extend our study to many other cancer types. In summary, this proposal is based on a novel mechanism of mutant p53 action. This knowledge can be used to design new therapeutic approaches for the treatment of diverse human cancers associated with various p53 mutations.
