  • Primary Site: Small intestine
  • Area of Inquiry: Mapping NET dependencies

General Description

Dr. Shivdasani’s laboratory studies how gastrointestinal stem cells make the decision to stop behaving like a stem cell and instead to differentiate into a neuroendocrine cell that might someday become a neuroendocrine tumor cell.  Dr. Shivdasani will study how epigenetic regulation controls the process by which a stem cell becomes a neuroendocrine cell and to identify how changes in epigenetic regulation can promote development of neuroendocrine tumors. Epigenetic regulators determine which genes are turned on or off under specific conditions in a cell. While genes contain the instructions for assembling proteins, it is through epigenetic regulation that cells are able to control whether or not these proteins are actually produced.
