A genetic 'gang of 4' drives spread of breast cancer

... growth and metastasis, the researchers found that turning off all four together had a far more dramatic effect on halting cancer growth and metastasis. Metastasis occurs when cells from a primary tumor break off and invade another organ. It is the deadliest transformation that a cancer can undergo, and ther...

UTSA researchers examine effects of global warming on Antarctic

... Department of Earth and Environmental Science are turning their attention to the South Pole to find out if global warming is having similar effects in the frigid Antarctic region. UTSA Earth and Environmental Science Assistant Professor Hongjie Xie and doctoral student Burcu Cicek are analyzing data coll...

Bacterial walls come tumbling down

... that can be exploited by antibiotics, progress in turning up bona fide drug targets has been slow. The cell wall enzymes in particular have tantalized scientists, Strynadka said. "The cell wall has all the hallmarks of a great drug target," she explained. "It is essential to the survival of all bacteria. Th...

Study finds surfing safer than soccer

...ies reported. This is likely due to the aggressive turning and aerial maneuvers, which score highly in competitions, but also appear to place high stress on a surfer's knee," says Nathanson, who is also an emergency physician at The Miriam Hospital and an assistant professor at Brown Medical School, both in ...

Scripps research study shows humans and plants share common regulatory pathway

...1 and protecting it from degradation. In contrast, turning off SGT1 did not alter levels of Nod1." In an earlier study, Ulevitch’s laboratory reported that Nod1 also interacted with the COP9 complex, a multiprotein complex that is known to play a role in a number of development pathways in plants and tha...

Novel system developed to turn data into real-time, interactive 3-D images

...nd efficiently study hundreds of images at once by turning the data into a three-dimensional (3-D) object that appears to float in midair." The technology will allow for manipulation of the volume-rendered object in real-time, giving physicians the ability to add and remove data, as well as to instantly ...

Mule deer moms rescue other fawns

...ed there as long as the calls played, twisting and turning as they confronted the perceived attackers. Whitetail mothers that came close to the speaker tended to withdraw right away and then stayed safely outside that distance. The behaviour of mule deer defies traditional explanations that parental care,...

Fat fish put obesity on the hook

...th this model, we are a step closer to temporarily turning off or diminishing the fat-storing mechanisms that were once crucial to the survival of our species. The zebrafish has become a model animal for the study of many diseases because it has a backbone and because its genetics have been well described. T...

Herpes virus hijacks DNA repair process

...ified a protein that can trick the mouse cell into turning on the DNA damage response. They also showed that Epstein-Barr virus, a human herpes virus, has a similar protein. Scientists found that blocking murine herpes virus from activating the DNA damage response caused viral replication rates to plummet. ...

Researchers examine carbon capture and storage to combat global warming

...earchers said. Of all the projects, only one is turning a profit without recovering oil. Sleipner, an industrial-scale project run by Norwegian oil company Statoil, injects carbon dioxide into a deep saline aquifer beneath the North Sea floor. Its economic success, scientists say, is due to the presenc...

U-M researchers discover gene switched off in cancer can be turned on

...se existing drugs, which showed some usefulness in turning on the BRM gene. But new drugs would need to be developed to be more effective in reactivating this gene in cancer cells. Still, researchers are excited about the potential this finding could have in leading to new targets for cancer treatment. “T...
