Salk scientists find two key proteins that regulate the growth of mammary stem cells and could contribute to breast cancer By carefully controlling the levels of two proteins, researchers at the Salk Institute have discovered how to keep mammary stem cells—those that can form breast tissue—alive and functioning in the lab. The new ability to propagate mammary stem cells is allowing them to study both breast development and the formation of breast cancers. "What we've shown is that...

Salk Institute scientists show how regulation of a key damage response protein can make the difference between survival and death after radiation Scientists at the Salk Institute for Biological Studies have found clues to the functioning of an important damage response protein in cells. The protein, p53, can cause cells to stop dividing or even to commit suicide when they show signs of DNA damage, and it is responsible for much of the tissue destruction that follows exposure to ionizing...

A close collaboration between researchers at the Salk Institute for Biological Studies and the Institute for Advanced Study found that the tumor suppressor p53, long thought of as the "Guardian of the Genome," may do more than thwart cancer-causing mutations. It may also prevent established cancer cells from sliding toward a more aggressive, stem-like state by serving as a "Guardian against Genome Reprogramming." The new work, reported by Geoffrey M. Wahl, Ph.D., and Benjamin Spike, Ph.D., at...

A collaborative study by researchers at the Salk Institute for Biological Studies uncovered that the tumor suppressor p53, which made its name as "guardian of the genome", not only stops cells that could become cancerous in their tracks but also controls somatic cell reprogramming.Although scientists have learned how to reprogram adult human cells such as skin cells into so-called induced pluripotent stem cells (iPSCs), the reprogramming efficiency is still woefully low. The Salk study,...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
