When oxygen is short, EGFR prevents maturation of cancer-fighting miRNAs

(University of Texas M. D. Anderson Cancer Center) Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers reported in an early online publication at Nature.

Scientists discover how rapamycin slows cell growth

(University of Montreal) University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal Cell, scientists from the University of Montreal explain how they found that the anti-cancer and anti-proliferative drug rapamycin slows down or prevents cells from dividing.

Vaccine blackjack: IL-21 critical to fight against viral infections

(Emory Health Sciences) Scientists at Emory Vaccine Center have shown that an immune regulatory molecule called IL-21 is needed for long-lasting antibody responses in mice against viral infections.

Cradle turns smartphone into handheld biosensor

(University of Illinois at Urbana-Champaign) Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. University of Illinois researchers have developed a cradle and app for the iPhone that uses the phone's built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. Although the cradle holds only about $200 of optical components, it performs as accurately as a large $50,000 spectrophotometer in the laboratory.

Ferrets, pigs susceptible to H7N9 avian influenza virus

(NIH/National Institute of Allergy and Infectious Diseases) Chinese and US scientists have used a virus isolated from a person who died from H7N9 avian influenza infection to determine whether the virus could infect and be transmitted between ferrets. Ferrets are often used as a mammalian model in influenza research, and efficient transmission of influenza virus between ferrets can provide clues as to how well the same process might occur in people.

UC Santa Barbara scientists discover cinnamon compounds' potential ability to prevent Alzheimer's

(University of California - Santa Barbara) Cinnamon: Can the red-brown spice with the unmistakable fragrance and variety of uses offer an important benefit? The common baking spice might hold the key to delaying the onset of -- or warding off -- the effects of Alzheimer's disease.

Emory, Georgia Tech receive first human exposome center grant in US

(Emory Health Sciences) Investigators at Rollins School of Public Health at Emory University, along with partners at the Georgia Institute of Technology, have received a $4 million grant over four years to establish the HERCULES Center at Emory University (Health and Exposome Research Center: Understanding Lifetime Exposures). The grant is the first exposome-based center grant awarded in the United States.

University of Illinois biophysicists measure mechanism that determines fate of living cells

(University of Illinois College of Engineering) For the first time, biophysicists at the University of Illinois at Urbana-Champaign have measured the molecular force required to mechanically transmit function-regulating signals within a cell. A new laboratory method, named the tension gauge tether approach, has made it possible to detect and measure the mechanics of the single-molecule interaction by which human cell receptors are activated.
