Welcome to the Yatsunyk Lab!

Our laboratory investigates how water-soluble porphyrins and other small molecule ligands interact with non-canonical tetrastranded DNA structures, quadruplexes, from telomeres and oncogenes promoters in a specific manner, leading to cancer inhibition. We want to understand the mechanism of these interactions as well as the structural details of quadruplexes alone and in complex with porphyrins. This knowledge will pave a way for new and selective anticancer treatments. Our favorite techniques include X-ray crystallography, UV-vis, circular dichroism (CD), fluorescence resonance energy transfer (FRET), NMR, gel electrophoresis, and synthetic work. Most of the research is done by Swarthmore undergraduate students. We have strong collaborations with researchers from UPenn, NIST, University of Louisville and from the European Institute of Chemistry and Biology in France.
