Protein power: Researchers trigger insulin production in diabetic mice
01-08-2008 · EurekAlert!University of Florida researchers have coaxed liver and pancreatic cells within diabetic mice into churning out insulin by injecting the animals with a naturally occurring protein called Pdx1, opening up a new research avenue that someday could lead to safer treatments for type 1 diabetes. Pdx1 activates the genes controlling the development of the pancreas cells that make and release insulin to maintain safe levels of glucose in the body.

- Low dose of serotonin-acting chemical improves blood sugar tolerance
11-06-2007 · EurekAlert!
An appetite-suppressing chemical also improves glucose tolerance and lowers insulin levels in obese and diabetic mice, researchers report in the November issue of Cell Metabolism, a publication of Cell Press. Importantly, the researchers found, those effects of the drug occurred at a low dose that had no influence on feeding behavior, body weight, activity level, or energy expenditure.

- Insulin -- in need of some restraint?
03-06-2007 · EurekAlert!
Knocking out the gene for a peptide associated with insulin secretion protects mice against the harmful effects of a high-fat diet, report researchers at the Salk Institute for Biological Studies. Their findings, detailed in the Proceedings of the National Academy of Sciences, suggest that urocortin 3, a new peptide recently discovered in the insulin secreting cells of the pancreas, plays a role in the increased production of insulin in response to high caloric intake in animals.

11-13-2007 · EurekAlert!
A diet low in carbohydrates may help stunt the growth of prostate tumors, according to a new study led by Duke Prostate Center researchers. The study, in mice, suggests that a reduction in insulin production possibly caused by fewer carbohydrates may stall tumor growth.

- Despite overeating, morbidly obese mice gain protection against diabetes
08-23-2007 · EurekAlert!
The "world's fattest mice" can overeat without developing insulin resistance or diabetes thanks to a glut of a key hormone, a dichotomy that helps explain why not all obese people are diabetic, a UT Southwestern Medical Center researcher has found.

- Glucose levels trigger compensation for type 2 diabetics
01-02-2007 · EurekAlert!
Many individuals with type 2 diabetes are diabetic because their body no longer responds to the hormone insulin. Before they become clinically diabetic their body tries to compensate for the lack of insulin responsiveness by increasing the mass of insulin-secreting cells (beta cells) in the pancreas. A new study shows that in mice with high-fat diet-induced insulin resistance, changes in glucose concentration are likely to be the main trigger of increased beta-cell mass.

Treatment with the antibiotic myriocin can halt the growth of established arterial plaques in mice, researchers report. A new study reveals that statins actually increase the production of another protein that limits their benefit.

- First-ever study: lack of critical lubricant causes wear in joints
11-06-2007 · EurekAlert!
For the first time, researchers have linked increased friction with early wear in the joints of animals. Work led by Brown University physician and engineer Gregory Jay, MD, shows mice that do not produce the protein lubricin begin to show wear in their joints less than two weeks after birth. This finding not only points up the protective power of lubricin but also suggests that it could be used to prevent joint wear after an injury.

- New technique to 'see' and protect transplants successful in diabetic animal model
07-29-2007 · EurekAlert!
Researchers at Johns Hopkins have found a way to overcome a major stumbling block to developing successful insulin-cell transplants for people with type I diabetes. They developed a new technique encapsulates the insulin-producing cells in magnetic capsules, using an FDA-approved iron compound with an off-label use, which can be tracked by magnetic resonance imaging (MRI). The product, tested in swine and diabetic mice, also simultaneously avoids rejection by the immune system, likely a major reason for transplant failure.

Aluminum toxicity in acidic soils limits crop production in as much as half the world's arable land. Now, Cornell researchers have cloned a novel aluminum-tolerant gene in sorghum and expect to have genetically engineered aluminum-tolerant sorghum lines by next year.

- Duke researchers find physician resistance hinders diabetics use of cutting edge technology
10-13-2006 · EurekAlert!
Diabetic patients who use newer technologies such as insulin pumps and blood glucose monitoring devices are better able to manage their disease and adhere to treatment regimens, with less daily pain, than with conventional treatments, according to Duke University researchers. Yet researchers have found that the newer methods to manage diabetes are not being widely used because physicians may be reluctant to prescribe them, and even patients who are using them may not be deriving their full benefits.
