Our overarching goal is to discover new strategies to enhance responses in cancer patients to treatments that target aberrant signal transduction pathways that drive tumor growth. We engage in studies linking the bench and the bedside investigating the molecular pathogenesis of human cancers with a primary focus on lung cancer, the leading cause of cancer mortality. We use interdisciplinary approaches and next-generation functional genomics methodologies, relevant human lung cancer cell line and tumor model systems, and human lung cancer specimens and clinical data to define the molecular events that drive the growth human lung cancers (e.g. please see Bivona TG, et al Nature 471, 523-526, 24 March 2011; Zheng ZZ, et al, Bivona TG, Nature Genetics 2012). Based on our discoveries, we design novel, rational therapeutic strategies and translate our findings into clinical applications. Our laboratory investigations often lead to clinical trials testing novel, molecularly targeted cancer therapies that are aimed at improving the survival of genetically defined subsets of patients with lung and other lethal cancers.
There are several ongoing projects in the lab that are focused on functionally characterizing the lung cancer genome to develop new strategies to enhance the survival of lung cancer patients. In our studies, we leverage a conceptually and technically innovative and multidisciplinary approach using unbiased systems biology and chemical genetic screening strategies and detailed mechanistic studies in human lung cancer models.
1) Defining the underlying molecular mechanisms by which tumor cells become dependent upon mutant, activated forms of the epidermal growth factor receptor (EGFR) for their growth and survival (“oncogene dependence”).
2) Elucidating genetic and epigenetic determinants of driver oncogene dependence in genetically defined subsets of human lung cancers that are characterized by expression of an oncogenic kinase such as mutant BRAF or the EML4-ALK gene fusion.
3) Uncovering mechanisms of primary and secondary resistance to driver oncogene inhibition in lung cancers using cell line and mouse models of lung cancer to define molecular biomarkers and rational therapeutic targets to overcome treatment resistance in lung cancer patients.
4) Developing quantitative genetic interaction maps of signaling networks driving resistance to oncogene-targeted therapy in human lung cancers to develop synergistic cocktail therapies that could enhance the survival of appropriately selected, molecularly defined subsets of lung cancer patients.
