Katerina Gurova, MD, PhD
Dr. Katerina Gurova came to Roswell Park Cancer Institute (RPCI) from Cleveland BioLabs, where she served as Director of Anti-Cancer Drug Discovery. Before joining Cleveland BioLabs, she worked as a Project Scientist in the Department of Molecular Genetics at The Cleveland Clinic.
Dr. Gurova earned her medical degree from the Sechenov Medical Academy and a doctoral degree in experimental oncology from the Blokhin Cancer Research Center, both located in Moscow, Russia.
Dr. Gurova’s research interests are focused on the discovery and development of new anticancer drugs. Specifically, she identified a new class of prospective anticancer agents named curaxins which are capable of simultaneous targeting of several signal transduction pathways that are frequently deregulated in cancer, including p53 and NF-kappaB. Her laboratory at RPCI is working on deciphering molecular mechanisms, optimizing therapeutic properties of curaxins and on the development of new approaches to treatment of hormone-refractory prostate cancer.
Dr. Gurova is a member of the American Association for Cancer Research.
Dr. Gurova has authored several research articles and reviews on the mechanisms of cancer cell death. For a complete list of publications click here.
Major goal of our lab is the discovery of new anti-cancer agents through different approaches, their testing and early stage development as well as understanding the mechanisms of their activity. We have molecules at different stage of development, including one, curaxin CBL0137, in clincial trial.
Our current focus area is chromatin remodeling factors, their role in normal development and disease, DNA damage detection and prevention. Specifically we are concentrated right now on a Facilitates Chromatin Transcription (FACT) complex. We have found that it may be used as a marker of aggressive poorly differentiated cancers with low overall survival. We are in the process of validation of FACT as an anti-cancer target through identification and testing of chemical FACT inhibitors and genetically modified mice to see consequences of FACT inhibition for tumors and the whole organism.
We also believe that FACt may be involved in the protection of our genome from DNA damage through the control of DNA topology. FACT can detect abnormal or alternative DNA structures and convey signal to p53 activation. Thus FACT has been a sensor and mediator of a novel type of cell stress-DNA superhelical or torsional stress, which is the situation when DNA is over or undertwisted, and may result in DNA breaks.
Additional area of research in the lab is cell and tissue specific response to DNA damage and p53 activation. We have identified small molecules which induce DNA damage and p53 response only in breast and prostate tumor cells and we are trying to understand their mechanism of action.
