Ten years after the human genome was first published, researchers have found new clues into the machinery that influences gene function. The team, led by Bradley Bernstein, an associate professor of pathology at Massachusetts General Hospital and Harvard Medical School and senior associate member at the Ó³»´«Ã½, and Aviv Regev, a core member at the Ó³»´«Ã½ and associate professor at MIT, focused on chromatin, the complex of non-genetic material associated with DNA that drives gene expression, and specific regulators that orchestrate chromatin activity.
