Research Experience

Protein glycosylation

a)   MUC1, a high-molecular weight glycoprotein, secreted and expressed at the cellular surface of various epithelial tissues, is the major carrier of altered glycosylation in carcinomas. The functional significance on the molecular level of the changes in O-linked MUC1 glycosylation in cancer is still difficult to determine due to the intrinsic genetic instability and cellular heterogeneity of tumors. In addition, the cluster glycoside effect and steric hindrance effect of neighboring glycans on binding to glycan-binding proteins (lectins) have not been well characterized and are poorly understood due to the lack of availability of rigorously controlled and structurally defined model compounds. To address this knowledge gap, my group has designed and prepared novel tools to study a particular carbohydrate recognition mechanism, as well as developed a novel analytical assay for low affinity glycan-protein interactions based on AlphaScreen technology, using a range of biophysical techniques to probe the biological significance of cellular glycosylation. These tools are an invaluable tool for increasing our understanding of the role of MUC1 in cancer cell biology and immunology. Based on our experimental evidence of importance of the peptide part in the recognition process, a detailed elucidation of the affinity and specificity amongst lectins for glycans as they exist in their natural cellular context, conjugated to a protein, is needed for biomedical applications. I served as the PI in these studies.

b)   As part of a team project, I have studied the role of type IV collagen glycosylation on integrin binding, and consequently, modulation of cell recognition and signaling. We have found that reduced glycosylation significantly impacted binding of integrins and proposed a possible “cryptic sites” mechanism by which tumor cells may invade the basement membrane and extracellular matrix, the sequence of events leading to the development of tumor cell invasion and metastasis. Furthermore, we have investigated how glycosylation of ADAM17 affects its activity and inhibition. Our results suggest that glycosylation of ADAM17 can affect cell signaling in disease, and might provide opportunities for therapeutic intervention using exosite inhibitors. My role on these projects was the synthesis of substrates (non-glycosylated and glycosylated), as well as with incorporated FRET labels.

Antibacterial Research

My early contribution to science was in the field of antibacterial research during my postdoctoral studies at the Wistar Institute, Philadelphia. I was involved in the design and synthesis of naturally-occurring peptide antibiotics on a scale that would allow determination of their antibacterial efficacy, activity spectrum, mode of action, and structure-activity relationship analysis. My accomplishments in the field of antibacterial peptides include: development of a new efficient method for the synthesis of the head-to-tail cyclic peptides on a scale required for drug development; discovery of a new bacterial target of proline-rich cationic antibacterial peptides; and development of new peptide therapeutics for treatment of UTI infections and peptide-based drug delivery systems.
