2-protein team would be lost without each other
04-19-2007 · EurekAlert!Just as a hard-charging person sometimes needs a calming partner to be more effective, so it is with a pair of critical proteins that promote cell division and growth in the rapidly expanding root tip of plants. This emerging picture of the complex interplay between genes and proteins is the latest finding to come from Duke University researchers' examination of the model mustard plant Arabidopsis thaliana.

- Protein suppresses spread of prostate cancer
07-20-2007 · Massachusetts Institute of Technology (MIT)
A protein whose function is lost in a broad array of cancers normally suppresses the spread of prostate cancer, MIT researchers and colleagues have shown. Testing for loss of the protein could help clinicians tell which cancers are more likely to metastasize.

- Stealth technology maintains fitness after sex
01-11-2007 · EurekAlert!
Pathogens can become superbugs without their even knowing it, research published today in Science shows. 'Stealth' plasmids -- circular 'DNA parasites' of bacteria that can carry antibiotic-resistance genes -- produce a protein that increases the chances of spread of the antibiotic-resistant strain. The team, from Trinity College Dublin, Ireland, and the Wellcome Trust Sanger Institute, Cambridge, UK, suggest that low-cost plasmids, described for the first time in the study, are a threat to use of antibiotics.

- Brown team finds crucial protein role in deadly prion spread
01-23-2007 · EurekAlert!
Brown University biologists have made another major advance toward understanding the deadly work of prions, the culprits behind fatal brain diseases such as mad cow and their human counterparts. In new work published online in PLoS Biology, researchers show that the protein Hsp104 must be present and active for prions to multiply and cause disease.

- Marker predicts pancreatic cancer outcome after surgery, Jefferson surgeon finds
06-22-2007 · EurekAlert!
A team of researchers, led by surgeons at the Kimmel Cancer Center at Jefferson in Philadelphia, has found further evidence supporting the ability of a protein to predict how well a patient with advanced pancreatic cancer will do after surgery, chemotherapy and radiation.

- Scientists take next step in understanding potential target for Ovarian cancer treatment
07-16-2007 · EurekAlert!
A traffic cop protein in the cell may have an even more important role: transporting a messenger protein that tells components in the nucleus to stop cell growth. Scientists are studying the normal function of a protein called 'km23', the traffic cop protein, because the team previously found altered forms of the protein in 42 percent of tumor tissue samples taken from women with Ovarian cancer. The discovery of this additional role may lead to diagnostic tools and earlier treatments for Ovarian cancer.

- Aggression, rather than celebration, drives alcohol consumption in rugby spectators
03-29-2007 · EurekAlert!
Research news published today in Criminal Behavior and Mental Health drew two main findings from a survey of rugby supporters entering and leaving the Millennium Stadium in Cardiff: Spectators in the winning and drawing groups rated themselves as more aggressive than those whose team just lost; and more aggressive spectators intended to drink more alcohol after the match.

- Colon cancer a disease of hormone deficiency, Jefferson team finds
08-01-2007 · EurekAlert!
Researchers have found new evidence suggesting that colon cancer is a disease of missing hormones that could potentially be treated by hormone replacement therapy.Early in colon cancer development, two intestinal cell growth-controlling hormones are "lost," disrupting the activity of the hormones' receptor, GCC. Using two mouse models of colon cancer development in people, the scientists showed that GCC signaling blocks tumors from forming, meaning that colon cancer could be a disease of hormone insufficiency.
