miRNA-mediated silencing of mRNAs

... of whether miRNAs silence gene expression without affecting mRNA levels has been controversial, and conflicting results have been reported in the literature. Dr. Izaurralde explains that, "Our findings reveal that miRNAs silencing gene expression by at least two independent mechanisms: by repression of transl...

Mechanism for neurodenegerative diseases linked to transport proteins

...untington's, it is a rare but devastating disease, affecting one in 40,000 people, usually between the ages of 30 and 50. Huntington's strikes about four times as many. Neurodegenerative diseases like SBMA are caused by the lengthening of part of a gene that encodes repetitions of the amino acid glutamine in ...

Loosen up, DNA: Leukemia gene changes genetic packaging

...s have thought, exerting control over our genes by affecting whole swaths of chromosomes in global fashion, according to a paper in the September issue of Nature Genetics and appearing online August 6. While the research involving a cellular signaling system known as JAK/STAT focused on complex questions inv...

Gorilla susceptibility to Ebola virus: the cost of sociality

...e findings offer a unique glimpse into the factors affecting the threat the deadly virus poses to great apes. The work is reported in the July 12th issue of the journal Current Biology by a team of researchers including Damien Caillaud and colleagues from the University of Montpellier and the University of R...

Funding and bureaucracy, not access to journals, are chief obstacles to scientific productivity

... out what researchers thought were the main issues affecting their productivity. This, together with an analysis of the peer-reviewed literature enabled the team to identify a list of 16 key factors. Online polling methods in conjunction with conjoint analysis techniques were used to establish the relative p...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops

"At AAPS, we are committed to tackling the latest issues ?even the toughest issues ?and exposing our members to disparate points o...

Beekeepers work hard for the honey, despite changing tupelo forest

...otic pests, land development and other factors are affecting tupelo honey production, an important regional industry that contributes about $2.4 million a year to Florida's economy. The researchers' findings will allow beekeepers to develop collective strategies to defend their livelihood, Watson said. That'...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

...trying to find out what stresses them and how it's affecting coral health." If the researchers can determine the specific causes of pollution that are harming coral, it then will be up to governments, organizations and residents to decide whether it's worth the cost of solving whatever problems are discovere...

Tiny airborne particles are a major cause of climate change

...provide a comprehensive picture of how they may be affecting our climate. Cloud formation is dependent upon the presence of small amounts of aerosols such as sea salt and desert dust. These tiny particles serve as the seeds around which water vapor in the air condenses, forming tiny water droplets that rise...

Novel therapy combinations gain ground in treating hepatitis

..., hepatitis has become a worldwide health problem, affecting millions of people in the U.S. and abroad. Researchers are experimenting with combinations of anti-inflammatory medicines like interferons to improve hepatitis symptoms. In research presented today at Digestive Disease Week® 2006 (DDW), new combina...

Wild bees and the flowers they pollinate are disappearing together

...two are locked in a vicious cycle in which each is affecting the other. It's also not clear as of yet what the ultimate causes of the declines are, although land use change, agricultural chemicals and climate change may be important factors. The researchers hope to clarify these issues with follow-up studies....

Researchers develop flood-tolerant California rice

...es the plant's oxygen and carbon dioxide supplies, affecting photosynthesis and respiration. Submerged, the plants lack the gases needed to produce sugar for cellular energy, resulting in death if submergence persists beyond four days. Bailey-Serres notes that access today to information about the rice geno...

Virtual realities against pain
