Igor G. Panyutin, PhD
Radiology and Imaging Sciences
MS, Moscow Institute of Physics and Technology (1982)
PhD, Moscow State University (1986)
Dr. Panyutin earned his MS degree in molecular biophysics from the Moscow Institute of Physics and Technology and PhD degree from the Lomonosov Moscow State University (Russia), and continued his research on conformational transitions in DNA in the Engelhardt Institute of Molecular Biology and then in the Zelinsky Institute of Organic Chemistry (Moscow, Russia). Since 1991, he has been at the NIH, first at NIDDK and then, since 1993, at the NIH Clinical Center, where he has been developing DNA-based radiopharmaceuticals for gene-targeted radiotherapy.
Dr. Panyutin’s research interests include sequence-specific targeting of DNA; gene targeting and gene expression regulation by sequence-specific molecules, such as triplex-forming oligonucleotides, peptide nucleic acids, and their analogs; delivery of DNA- and RNA-targeting probes into cell nuclei and their intracellular transport; utilization of Auger electron emitting radionuclides delivered by DNA sequence specific probes for gene inactivation; anti-gene radiotherapy; higher order DNA structures and DNA-protein interactions.
