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.

Congratulation to Liliya, Supriya, Scott and Rowen for publication of their article: "Interaction of a Cationic Porphyrin and its Metal Derivatives with G-Quadruplex DNA" in J. Phys. Chem. B

Congratulation to Thomas, Barrett, and Supriya for publication of their article: "Lowering the overall charge on TMPyP4 improves its selectivity for G-quadruplex DNA”  in Biochimie.

Deondre Jordan received travel award to attended Annual Biomedical Conference for Minority Students (ABRCMS). ABRCMS is a professional conference that brings together underrepresented students who plan to pursue a career in STEM. Deondre presented a talk titled:“Investigating the secondary structure of non-canonical DNA implicated in Cancer”. He was recognized for the excellent of his presentation with the Biochemistry award.

Liliya receives Camille and Henry Dreyfus Teacher-Scholar Award for her work titled: Deciphering the Structure and Dynamics of Quadruplex DNA and DNA-ligand complexes.
