Understanding proteins dysregulated in cancer is a vital step toward the discovery of effective targets for treatment.  Many cellular enzymes demonstrate aberrant activity in cancer, and a significant subset of them contain cysteine amino acid residues required for their function. 

Dr. Weerapana aims to use sophisticated chemical genetic approaches to develop novel small molecules that selectively target these cysteines, thus blocking protein function.  Her goal is to create a “chemical library” of these small molecules and use this library to identify compounds that affect cancer cell proliferation, migration and invasion in breast and ovarian cancer cell lines.  The cellular protein targets of these molecules will be identified, followed by analysis of their roles in cancer development and progression.  This multidisciplinary approach, encompassing aspects of synthetic chemistry, cell biology and proteomics, will identify new therapeutic targets and small molecule drug candidates for the diagnosis and treatment of cancer.
