Background

Dr. Charles Eberhart is a professor of pathology and oncology, and an associate professor of ophthalmology, at the Johns Hopkins University School of Medicine. His research primarily focuses on molecular genetics and treatment of medulloblastoma, glioblastoma, uveal melanoma and other tumors of the brain and eye. Dr. Eberhart serves as the director of the Divisions of Neuropathology and Ophthalmic Pathology.

Major research areas in his laboratory include targeting Notch and other developmentally important signaling pathways in tumors, identifying the genetic drivers of rare neoplasms in the brain and eye, and building new models of tumors using neural stem cells.

He received his undergraduate degree in biochemistry from the University of Texas at Austin and earned his M.D./Ph.D. from UT Southwestern Medical School. He also was a fellow at the Max Planck institute for one year. Dr. Eberhart completed both a residency in anatomic pathology and a fellowship in neuropathology at The Johns Hopkins Hospital, then joined the Johns Hopkins faculty in 2001.

Dr. Eberhart has been recognized with the Howard Hughes Medical Institute Postdoctoral Research Fellowship for Physicians, and career development awards from the Burroughs Wellcome Fund and the National Institutes of Health. He has published more than 200 original research articles, numerous case reports, reviews and book chapters, and is on the editorial board of the Journal of Neuro-Oncology, Brain Pathology and the Journal of Neuropathology and Experimental Neurology.

Research Summary

Dr. Eberhart and his lab members study the molecular genetics of medulloblastoma, low grade glioma, glioblastoma, uveal melanoma and other tumors of the brain and eye. One major focus is on Notch and other pathways which play a key role in both normal development and in neoplasia. They are currently analyzing the long terms effects of Notch blockade on cancer stem cells in brain and eye tumors, how therapeutic resistance emerges, and the basis of the sometimes antagonistic effects of various Notch receptors. They are also examining the role of c-Myc in the stem cell phenotype of cancer. Identifying novel genetic changes in ocular surface tumors and other poorly understood neoplasms represents another focus.

Lab

Dr. Eberhart works closely with Drs.Rodriguez and Raabe in a multidisciplinary research group. Their studies use our understanding of normal development to guide investigation of the neoplastic process. They have implicated Hedgehog, Notch and other developmentally significant signaling cascades in the initiation and ongoing growth of brain tumors. They are also engaged in preclinical testing of pharmacological agents that target multiple pathways in brain and eye tumors. To accomplish this they have generated new tumor models from surgical specimens and by making relevant oncogenic changes in progenitor cells. A related area of interest in the lab is the relationship between stem cells and cancer. The possibility that specific types of transformed stem cells represent the origins of brain and eye tumors, as well as the hypothesis that “cancer stem cells” are required for long-term tumor self renewal and growth, are both active areas of investigation.
