Turtles and other reptiles offer clues to the development of 4 chambers and to congenital heart disease Scientists at the Gladstone Institute of Cardiovascular Disease (GICD) have traced the evolution of the four-chambered human heart to a common genetic factor linked to the development of hearts in turtles and other reptiles. The research, published in the September 3 issue of the journal Nature, shows how a specific protein that turns on genes is involved in heart formation in turtles,...

Sequence of transcription factors may drive process to repair damaged hearts Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells. The discovery, reported in the current issue of the journal Nature, provides important new directions on how stem cells may be used to repair damaged hearts. For decades, scientists were unable to identify a single factor that could turn nonmuscle...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
