Gail Mandel is Senior Scientist at the Vollum Institute and a Professor in the Department of Biochemistry and Molecular Biology in the School of Medicine at OHSU. A valley girl at heart, she received her Ph.D. in Immunology from the University of California, Los Angeles in 1977, four years after receiving her B.A. in Biology. Mandel did her postdoctoral training at UCLA and the University of California, San Diego. She was an Instructor in the Department of Pathology at Harvard Medical School for two years before joining Molecular Medicine at Tufts-New England Medical Center in 1984. In 1989, Mandel was promoted to Associate Professor in the Department of Neurobiology & Behavior at Stony Brook University and advanced to the rank of Distinguished Professor before joining the Vollum Institute in 2006. She has been an Investigator with the Howard Hughes Medical Institute since 1997.


Summary of Current Research

The Mandel Lab research is focused on understanding how neuronal cell identity is established and maintained. Unexpectedly, the lab discovered that this is achieved primarily through a repressor mechanism. At the heart of this mechanism lies the DNA-binding protein, REST. Together with its interaction partners, REST controls the epigenetic status of neuronal gene chromatin. Knowledge of this mechanism provides a window into the molecular events governing nervous system formation.

The lab is exploiting embryonic stem cell differentiation and knock out animals to understand how the repressor complex is regulated during normal development. Using a novel strategy for characterizing transcription factor binding sites, they elucidated the REST genetic network and are studying how this network, and its associated chromatin signature, direct normal neuronal differentiation and contributes to autism spectrum disorders. Most recently, the Mandel lab extended their studies to explore neuronal-glial interactions, uncovering a role for glia in inducing neuronal dysfunction in Rett Syndrome, one of the most common causes of mental retardation in young girls. Their goal is to identify how the glial genes or proteins cause the underlying neuronal pathology.
