Dr. Tsankova is an Assistant Professor in Pathology, Neuroscience, and a member of the Friedman Brain Institute. Her laboratory studies the molecular mechanisms of gliomagenesis in endogenous human-based models. She is also a practicing neuropathologist. Dr. Tsankova received her Ph.D. from UT Southwestern Medical Center, where she trained with Dr. Eric Nestler. Under his guidance, she pioneered the studies of neuroepigenetics in the context of chronic stress/depression. Following the path of a Physician-Scientist, she completed her residency in Anatomic Pathology and fellowship in Neuropathology at Columbia University, where she became intrigued with studying the pathogenesis of human gliomas. She worked in the laboratory of Dr. Fiona Doetsch, where she developed novel techniques to isolate and characterize endogenous neural/glial progenitors from human brain, creating a transitional, human-based system to study epigenetic dysregulation during gliomagenesis. Previously an Assistant Professor at Columbia University and now one at Mount Sinai, Dr. Tsankova also has fruitful and ongoing collaborations with several investigators from the departments of Neurosurgery, Neuroscience, and Psychiatry at both institutions.

A major research endeavor of our lab is to better define the cellular and molecular mechanisms responsible for the neoplastic transformation of normal human neural progenitors into primary brain tumors and the progression of low-grade to high-grade gliomas. Particularly, we want to understand the role of epigenetics (DNA methylation, histone modifications, and beyond) during normal glial development and its dysregulation during gliomagenesis. We have developed unique, translational methodology for isolating glial progenitor (stem) cells from human brains, and are actively defining their epigenetic and transcriptional signatures. Our preliminary findings reveal distinct epigenetic changes at developmentally regulated gene targets, which might predispose a subset of glial progenitors in the brain toward a neoplastic fate. Discovering unique genetic and epigenetic alterations in preneoplastic glia within their in vivo niche will allow us and others to identify biomarkers for early detection and more effective treatment of human gliomas, including glioblastomas.
