Description of CVI Expertise

Executive Vice Dean and Chief Scientific Officer

Research Interests Epigenetic regulation of stem cell biology, developmental biology, and cardiovascular medicine.
Key words: Cardiac development, Neural crest, Transcription, Epigenetics, Stem cells, Nuclear architecture, Hopx.
Research Description The Epstein laboratory is interested in molecular mechanisms of cardiovascular development and stem cell biology, and the implications of these mechanisms for understanding human disease. Transgenic and knockout mouse models are used. The lab has a longstanding history in the genetic causes of congenital heart disease and transcriptional regulation of cell fate determination. Most recently, the lab has focused on epigenetics, including the role of histone deacetylases in cardiac development and adult heart function. Active projects involve the understanding of the packaging of DNA and chromatin in the nucleus in three dimensions (“nuclear architecture”) and the regulation of cell differentiation by protein complexes that tether regions of the genome to the nuclear periphery. The lab has pioneered the concept that entire gene programs that define cardiac cell types can be regulated through interactions between the nuclear lamina and the chromatin. The Epstein lab discovered the tumor suppressor and stem cell gene Hopx and continues to study its role in the heart and in numerous tissue-specific adult resident stem cells including those in the central nervous system, the intestine and the skin. Finally, the lab is using novel methods of engineering immune cells to develop proof-of-principle approaches for treating common cardiovascular disorders.
