Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
03-06-2007 · EurekAlert!Antifreeze or "ice structuring" proteins -- found in some fish, insects, plants, fungi and bacteria -- attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. Scientists have been puzzled, however, about why some ice structuring proteins, such as those found in the spruce budworm, are more active than others.

- An AIDS-related virus reveals more ways to cause cancer, Penn researchers find
10-08-2007 · EurekAlert!
Researchers have shed new light on how Kaposi's Sarcoma-associated Herpes Virus subverts normal cell machinery to cause cancer. A KSHV protein called latency-associated nuclear antigen (LANA) helps the virus hide out from the immune system in infected cells. When LANA takes the place of other proteins that control cell growth, it can cause uncontrolled cell replication.

In the first test of a new radar instrument, scientists have seen through more than a mile of Greenland ice to reveal an image of land that has been hidden for millions of years. Ohio State University scientists and their colleagues will use what they learn from the instrument, dubbed GISMO (for Global Ice Sheet Mapping Orbiter), to determine how global climate change will affect the ice.

- Rutgers scientists discover brain cell development process implicated in mental retardation
07-31-2007 · EurekAlert!
Scientists at Rutgers University have discovered a biological process in brain cell development that may help explain some causes of mental retardation. This understanding may one day help other researchers develop therapies that can reduce specific forms of retardation. Proteins of the Rho family, when excessively present in developing brain cells known as neurons, inhibit another protein, called cypin, that promotes healthy neuron development.

- Signal protein shows promise for blocking tumor promoters in skin cells
11-03-2006 · EurekAlert!
A protein with the ironic name "Srcasm" can counteract the effects of tumor-promoting molecules in skin cells. Using animal models, the researchers discovered that Srcasm acts like a brake in epithelial cells, preventing uncontrolled cell growth caused by a family of proteins called Src kinases. This finding, published online in the Journal of Biological Chemistry, suggests a target for future gene therapy to treat skin, head, neck, colon and breast cancers.
