Albright Creative Research Experience (ACRE) Undergraduate Research – Directed by Professors Pamela Artz and Jeffery Wolbach, I developed a computational model to predict small molecule drug-vehicle interactions and complemented predictions with spectroscopic methods to validate precision of computational outcomes.
Current Research Activities:
We are interested in developing biophysical studies to elucidate the mechanism of activation of glutaminase isoform C (GAC), a novel target for the treatment of human cancers by selectively inhibiting the over-activation of glutamine metabolism, caused by an increase in GAC activity, observed in many cancer cell lines. This glutamine consumption, termed ‘glutamine addiction’, is a result of transformed malignant cells increased need for carbon sources for high rates of proliferation. In conjunction with understanding the mechanism of this oncogenic target, it is of interest to understand the precise metabolic transformation associated with cells conversion to the malignant state. Understanding the marked changes in the metabolic profile of cancer cells could elucidate novel therapeutic targets for the treatment of human cancers that are specific to transformed cells metabolic needs. In order to study this change in metabolism, I make use of a stable cell line that transforms to the malignant state upon induction of the oncogene Dbl (for Diffuse B cell lymphoma) and use sensitive analytical techniques such as NMR spectroscopy, High Performance Liquid Chromatography (HPLC), and Mass Spectrometry (MS), to monitor metabolites of interest during the transformation process.
