New protein provides clue to diabetes

... he says. "But so far, there aren't any drugs that act directly on this pathway. Now we can begin to speculate, for example, that a drug which blocks TUG might enhance a cell's ability to absorb glucose. It's an hypothesis, but an easy one to test." Joseph Avruch, professor at Harvard Medical School and...

Mathematical modeling predicts cellular communication

...epends on how well its cells communicate. Proteins act as molecular switchboard operators to keep the lines of communication open and the flow of cellular messages on track. But charting the protein interactions, signaling pathways, and other elements that regulate these networks is no small feat. There ...

Gene expression tied to social behavior in honey bees

... than usual while others will grow up normally and act as nurses, making for age-matched young nurses and foragers. Age-matched old foragers and old nurses also were obtained from these colonies. A dominant pattern of gene expression emerged, and it "was clearly associated with behavior," the researcher...

Zebrafish genetic research results in significant discovery for geobiologists

...ars of zebrafish, the researchers report. Otoliths act as inert weights involved in the perception of gravity, and in fish are involved in the perception of sound. In human ears, biominerals are present in the form of "otoconia," or "ear dust," which also are made of calcium carbonate, but the structures...

Brookhaven Lab develops 'ThraxVac' to clean up anthrax

...fically, alpha particles emitted from polonium-210 act as a static eliminator in paper mills and other industries. Alpha particles in ThraxVac can be used to decontaminate not only large surfaces, but also intricate machinery and moving parts, without impairment of function. Potential users include munic...

Using plants and microbes to purify polluted industrial wastewater

... by contrast, grow and clean themselves while they act as super-efficient absorbers of phosphates, nitrates and other environmental hazards. The INDCONWET project applies these natural abilities to industrial wastewater. Toxic by-products in run-off from industrial plants can contaminate drinking water s...

McMaster University researchers race to SARS vaccine development

... vaccine based on the adenovirus vector that would act as a carrier within the body. The McMaster group is also working with the SARS Initiative of the Canadian Institutes for Health Research (CIHR) and the National Centres of Excellence in Vaccine and Immunotherapy (CANVAC). "This is an important step...

Discovering what genes do the high-throughput way

...t the bigger picture. You can find out which genes act together to do something, so you begin to build up a system-wide understanding of how cells work. Genes work in a community to do something, not on their own. With big-scale experiments you can start to see the internal logic of the cell." The screen...

Scientists switch components in cell circuits: Possible new technology, therapy

... to use this technology to engineer cells that can act as cheap and robust sensors or computers, for example. You might be able to engineer cells that act like an artificial pancreas. In principle it may be possible to combat cancer by designing a signal...

Identifying cancer genes Will it really lead to better treatment?

...at mutated cancer genes have already been shown to act effectively. "Undoubtedly, these advances have changed the way we think about cancer drug development. BRAF is a promising target and we have initiated a program of drug development targeted at this gene. Early lead molecules have already been foun...

Nasal contribution to breathing with exercise: The effect of race and gender

...led particles and gases to the lungs. The nose can act as an effective filter to prevent penetration of particles and gases to the lower respiratory tract. Gases that are very water soluble or reactive (such as ozone) can be extracted in the nose by as much as 95% during breathing. Very large and very sm...

Moving the target for osteoporosis treatment

...ey substances journeyed from the brain to find and act on bone throughout the body. The MCG finding could lead to development of ACTH analogues that specifically activate receptors in the bone, prompting bone production. But first the researchers are developing a mouse that lacks this receptor; Dr. Isa...

Lasker Award honors Rockefeller University biochemist for pioneering studies of gene activation

... The coactivators are large protein complexes that act like mediators or bridges between activators or repressors and the general transcription machinery, thereby providing the cell with added control over gene activity. Control of gene expression -- the proper activation or silencing of genes in cells -...

New study begins to unravel fate of toxic pollutants harbored in Arctic waters

...t several decades. These cold corners of the earth act as a sink of sorts chemicals used in industry and agriculture worldwide slowly migrate to and settle there in sizeable quantities in water, snow, ice, soil and vegetation. In a new study, researchers found that the pollutant breakdown process depe...

How tea works against skin cancer

...plement sunscreens currently in use, most of which act by absorbing UV rays. Citing work by C.S. Yong at Rutgers, Dong said that one would need to drink seven cups a day of strong tea to reach the same levels of tea polyphenols as were applied to mice in these experiments. Dong himself enjoys plenty of...

New Colorado U. study shows increase in fungal metabolism under the snow

... by scientists of whether snow-covered regions can act as "sinks," or storage areas, for CO2, he said. A paper on the subject by Schmidt, Christopher Schadt and Andrew Martin from CU-Boulder and David Lipson from San Diego State University will appear in the Sept. 5 issue of Science magazine. About 40 pe...

Dual action anthrax vaccine more effective

One is protective antigen, a protein that joins with another called lethal factor to make the anthrax lethal toxin that kills immune cells. This combi...

Research on relative species abundance provides new theoretical foundation

... instead of assuming all species are different and act differently. Over time, he began to discover that many patterns that had heretofore been explained by "niches" might have a simpler explanation. Hubbell began to formulate what is now generally called "Neutral Theory." He believes that Symmetric Neut...
