Brief Description of Project:
We are studying the in vitro (tissue culture) and in vivo (nude mouse orthotopic xenograft) sensitivities and resistance of a large number of lung and breast cancer cell lines to standard and experimental chemotherapy agents. These include drugs in the "pipelines" of pharmaceutical and biotech companies that will be coming into clinical trials. We also perform genome wide gene expression profiles using microarray technology. This allows us to develop gene expression signatures for sensitivity and resistance to individual drugs. We plan to translate this information into clinical application by sampling a patient's tumor before chemotherapy is given, performing expression profiling, and then using that information to select individualized chemotherapy for each patient. We are performing a large number of related experiments including the isolation of "stem cells" from lung cancers that are probably the reason for the immortal growth of human tumors in patients and also determining there sensitivity and resistance to chemotherapy. Finally, our lab has developed new systems for studying individual genetic events in the molecular pathogenesis of lung cancer. We do this using new immortalized human bronchial epithelial cell lines we have developed and then genetically manipulating with defined oncogenic changes and monitor their progression towards the malignant phenotype.
