Biologists have found that a key protein that regulates the biological clocks of mammals also regulates glucose production in the liver and that altering the levels of this protein can improve the health of diabetic mice. Their discovery, detailed in this week's advanced online publication of the journal Nature Medicine, provides an entirely new biochemical approach for scientists to develop treatments for obesity and type 2 diabetes. It also raises the interesting possibility that some of...

Cancer-cell quirk could be exploited to develop new drugs that starve tumors In a paper appearing in the Sept. 16 online edition of Science, Matthew Vander Heiden assistant professor of biology and member of the David H. Koch Institute for Integrative Cancer Research at MIT and researchers at Harvard University report a previously unknown element of cancer cells' peculiar metabolism. They found that cells can trigger an alternative biochemical pathway that speeds up their metabolism and...

Scientists have overturned the conventional wisdom that cooperation is essential for the well-being of the whole population, finding evidence that slackers can sometimes help the common good. Researchers, from Imperial College London, the Universities of Bath and Oxford, University College London and the Max Planck Institute for Evolutionary Biology studied populations of yeast and found that a mixture of 'co-operators' and 'cheats' grew faster than a more utopian one of only "co-operators."...

Findings could aid in understanding diabetes, related conditions Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism. By studying the surface of healthy, live fat cells in rats, researchers were able to understand the process by which cells take in glucose. Next, they plan to observe the fat cells of people...

Research led by the Warwick Medical School at the University of Warwick has found that unhealthy glucose levels in patients with diabetes can cause significantly more problems for the body than just the well-known symptoms of the disease such as kidney damage and circulation problems. The raised glucose can also form what can be described as a sugar coating that can effectively smother and block the mechanisms our bodies use to detect and fight bacterial and fungal infections. In diabetes,...

Scientists from Department of Exercise and Sport Sciences have in collaboration with colleagues at Harvard University discovered a novel molecular pathway which is activated in muscles during exercise. Skeletal muscles combust both lipids and carbohydrates during exercise. The carbohydrates consist of both glycogen stored in the muscles as well as glucose extracted from the blood. Being a major sink for glucose disposal, skeletal muscle represents an important model tissue for studying the...

In the news release, Study on Fructose and Pancreatic Cancer Generates Premature and Potentially Misleading Conclusions, issued 03-Aug-2010 by the Corn Refiners Association over PR Newswire, the source organization should be "Corn Refiners Association" rather than "Cancer Research Alliance", as incorrectly transmitted by PR Newswire. The complete, corrected release follows: Study on Fructose and Pancreatic Cancer Generates Premature and Potentially Misleading Conclusions WASHINGTON,...

WASHINGTON, Aug. 3 /PRNewswire-USNewswire/ -- A study published in the August issue of Cancer Research (1) has resulted in several premature and potentially misleading conclusions when it comes to fructose and its effect on pancreatic tumor cells. Unfortunately, the media covering this story, and even the authors, have been too quick to extrapolate the results of laboratory research on pure fructose to real-world conditions, which is not appropriate or helpful to consumers. The main...

Modeling the action of cellulases on cellulose to improve efficiency of sugar production Scientists are working hard to develop the tools and find the organisms to break down the complex structure of plant cellulose into its component sugars "“ the key step toward fermentation of those sugars into usable biofuel. This process needs to be simple and economically efficient before cellulosic biofuels can compete with fossil fuels for transportation energy use. As with any exploration of...

Having discovered a dramatic increase of an easy-to-detect enzyme in the red blood cells of people with diabetes and prediabetes, Johns Hopkins scientists say the discovery could lead to a simple, routine test for detecting the subtle onset of the disease, before symptoms or complications occur and in time to reverse its course. Pilot studies, published online April 22 in Diabetes, show the enzyme O-GlcNAcase is up to two to three times higher in people with diabetes and prediabetes than in...
