My laboratory research is directed at using high-throughput profiling techniques to identify candidate predictive biomarkers and potential new therapeutic targets in lung and head and neck cancers. Specific markers of interest which are being further investigated as therapeutic targets include the DNA repair protein PARP1 in small cell lung cancer and the tyrosine kinase Ax1 in non-small cell lung cancer and head and neck cancers.
Projects/Techniques: Investigations of these targets and predictive biomarkers primarily involve in vitro procedures with target knockdown by siRNA, drug sensitivity screening, and molecular profiling by reverse phase protein array, SNP array, mRNA microarray, and various molecular biology techniques. Xenograft models are used to assess in vivo drug response and mechanisms of action.
