Description

Upon completion of postdoctoral training, Dr. Levenson joined the Northwestern University Medical School faculty where she served for ten continuous years. Dr. Levenson worked at the University of Mississippi Medical Center, Cancer Institute from 2010-15. Dr. Levenson joined Long Island University, College of Pharmacy and Health Sciences as an Associate Dean for Research and Graduate Studies in 2016. Levenson‘s interest is in cancer research, specifically, in molecular mechanisms of hormone-dependent breast and prostate cancer. For the past several years her laboratory has focused on understanding epigenetic mechanisms of prostate cancer progression and metastasis and on utilization of dietary agents, such as resveratrol and its analogs for cancer chemoprevention and treatment. Dr. Levenson is an active reviewer for numerous journals, serves on the Editorial Boards of several journals, and is a member of national and international review panels. She is the author of more than 50 peer-reviewed publications, four book chapters and more than 70 abstracts.

Research Synopsis

Identification of "bone metastatic signature" couple of years ago allowed us to focus on selected candidate genes that hold promise as potential biomarkers and therapeutic targets of bone metastases. We have shown that one of these genes, metastasis-associated protein 1 (MTA1), which is a chromatin modifier, plays a critical role in prostate cancer progression and metastasis by inhibiting apoptosis and promoting angiogenesis. We also have evidence that MTA1 can serve as an independent prognostic marker for aggressive prostate cancer, particularly in African American men. Currently, we aim to understand MTA1-mediated genetic and epigenetic mechanisms in prostate cancer pathogenesis. We have shown that MTA1/ HDAC1/2 inactivate tumor suppressors p53 and PTEN leading to inhibition of apoptosis and promotion of pAkt-mediated survival pathways. Using small interfering RNA technology, we have found that the loss of MTA1 decreases the proliferative and metastatic potential of cells in vitro and in vivo, particularly through mechanisms associated with the induction of apoptosis and reduction of angiogenesis. In addition, the role of MTA1 in the epithelial-to-mesenchymal transition and radioresistance in prostate cancer is of interest. While working with already identified target candidates such as pAkt, HIF1-α, and E-cadherin, we are interested in identifying new potential MTA1-associated high-risk biomarkers. At the moment, we are analyzing our MTA1 ChIP-Seq data which identified about 33,000 direct MTA1-DNA binding peaks in the mouse genome. Another active project is on epigenetic regulatory network that is represented by microRNAs and Epi-microRNAs. Finally, one of the major interest of the lab is potential chemopreventive and therapeutic efficacy of dietary stilbenes and other phytochemicals in cancer. We found that pterostilbene, a natural analog of resveratrol, inhibits MTA1 and rescues acetylation of tumor suppressors’ p53 and PTEN in prostate cancer. The novel MTA1-mediated epigenetic mechanisms of action of dietary compounds is under intensive investigation with pre-clinical animal testing using xenografts and transgenic mice.
