Esther Penni Black - PH.D.
Dr. Black received a Ph.D. at the University of Florida in Biomedical Sciences. Her thesis focused on transcriptional regulation in vaccinia virus. Dr. Black completed a postdoctoral fellowship in the laboratory of Joseph Nevins at Duke University. While at Duke, she initiated experiments to examine oncogenic signaling pathways using both biochemical and genomics tools.
Dr. Black's lab focuses on understanding oncogenic signaling cascades in both human and mouse systems. Our lab uses genomics and bioinformatics tools trained to predict deregulation of signaling cascades in non-small cell lung cancers and potentially other cancers. DNA microarray technology, when combined with bioinformatics, has proven valuable in dissecting the complexity of the oncogenic process. We hope to utilize these technologies to understand basic biological questions as well as to improve patient care in targeting therapies to the molecular events deregulated in specific patient populations. The data from microarray experiments will also lead to opportunities for drug discovery and design efforts as we uncover molecular effectors of deregulated signaling cascades common to many types of cancers.
We recently developed a gene expression predictor of sensitivity to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI). We will soon validate the usefulness of that predictor in a pilot clinical study.
Using the microarray data we have generated to isolate the MAPK, PI3K/AKT and STAT3 signaling cascades in lung epithelial cells, we are both building predictive gene expression signatures of each event and using the gene expression data as a descriptive phenotype of each cascade. Specific effector molecules common to these signaling pathways are being investigated in cell culture systems with hopes of identifying molecules that may be targeted by inhibitory compounds as novel therapeutics for non-small cell lung cancer.
Finally, we will use gene expression signatures of pathway activation and other biomarkers of sensitivity to chemotherapeutic treatments to build a decision tree for individualized treatment of patients with recurrent or relapsed non-small cell lung cancer.
