Study reveals the protein structure of the human apoptosome

Programmed cell death, or apoptosis, plays a central role in the maintenance of human health by providing a line of defense against unrestricted cell growth that occurs in many cancers and AIDS as well as in neurodegenerative ...

New procedure allows long-term culturing of adult stem cells

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the August 6 issue of Cell Stem ...

Deadly fungus uses unexpected system to control its virulence

A research team led by UC San Francisco scientists has discovered a cellular signaling system that regulates the virulence of Cryptococcus neoformans, a fungus that has been estimated to cause nearly a million cases of meningitis ...

Protein structure reveals how cells regulate their skeletons

Insight into the regulation of cell skeleton structure has come from a study conducted by A*STAR researchers. The work, which solved a protein structure that has eluded scientists for 20 years, should lead to further insights ...

Signaling molecule crucial to stem cell reprogramming

While investigating a rare genetic disorder, researchers at the University of California, San Diego School of Medicine have discovered that a ubiquitous signaling molecule is crucial to cellular reprogramming, a finding with ...

New discovery in living cell signaling

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant ...

Breakthrough: Sensors monitor cells at work

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. These transported molecules ...
