Zinc transporters regulate pancreatic cancer

Zinc, an important trace element for healthy growth and development, can be related to pancreatic cancer. Too much ZIP4, a molecule that enables the transport of zinc into cells, promotes the growth and spread of pancreatic tumors cells, said a group of researchers from Baylor College of Medicine in Houston, The University of Texas M.D. Anderson Cancer Center and the University of Florida in Gainesville, in a report which appears online today in the Proceedings of the National Academy of Sciences.

Placenta uses a cloaking device similar to that used by parasites

The placenta uses a cloaking device similar to that used by parasites to avoid detection by the mother's immune system. MRC funded scientists looking to develop a diagnostic test for pre-eclampsia, a major and potentially fatal cause of fetal and maternal illness, made the amazing discovery which could have far reaching implications.

The key to unlocking the secret of highly specific DNAzyme catalysis

Using an extremely sensitive measurement technique, researchers at the University of Illinois have found clear evidence that a lead-specific DNAzyme uses the "lock and key" reaction mechanism.

Synthetic compound promotes death of lung-cancer cells, tumors

Human lung-cancer tumors grown in mice have been shown to regress or disappear when treated with a synthetic compound that mimics the action of a naturally occurring "death-promoting" protein found in cells, researchers at UT Southwestern Medical Center report.

Nitrite/nitrate-rich foods may help in heart attack survival

Nitrite/nitrate found in vegetables, cured meats and drinking water may help you survive a heart attack and recover quicker, according to a pre-clinical study led by a cardiovascular physiologist at The University of Texas Health Science Center at Houston.

Spinal cord reconstruction following injury

A new study has identified what may be a pivotal first step towards the regeneration of nerve cells following spinal cord injury, using the body's own stem cells.

Tiny fluorescent probes illuminate protein interactions in living cells

While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods, according to a report in Nature Chemical Biology.

Anti-inflammation molecule helps fight MS-like disease

An immune system messenger molecule that normally helps quiet inflammation could be an effective tool against multiple sclerosis (MS). Neurology researchers led by Abdolmohamad Rostami, M.D., Ph.D., professor and chair of the Department of Neurology at Jefferson Medical College of Thomas Jefferson University and the Jefferson Hospital for Neuroscience in Philadelphia, have found that the protein interkeukin-27 (IL-27) helped block the onset or reverse symptoms in animals with an MS-like disease.

Molecular docking unlocks function of enzymes

Fitting a key into a lock may seem like a simple task, but researchers at Texas A&M University are using a method that involves testing thousands of keys to unlock the functions of enzymes, and their findings could open the door for new targets for drug designs.

Inflammation causes insulin resistance not obesity

Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered that inflammation provoked by immune cells called macrophages leads to insulin resistance and Type 2 diabetes.

Research sheds new light on how joints work

Mice that don't produce lubricin, a thin film of protein found in the cartilage of joints, showed early wear and higher friction in their joints, a new study led by Brown University researchers shows.

Novel approaches to hypertension control

A hypertension vaccine could be an important alternative to conventional drug therapy because of patients' inconsistent drug intake - if further research supports results from a small study testing the safety and tolerability of a vaccine.

Potential new treatment for severe obesity

A team of researchers from the St Vincent's Campus in Sydney have developed a novel way to control the extreme weight loss, common in late stage cancer, which often speeds death.

Scientists in Australia discover how to switch hunger on and off

Scientists in Australia have found how to switch hunger on and off and they say their discovery could be used to stop weight loss in terminally ill patients or produce weight loss in the morbidly obese.

Discovery of new hemoglobin function

A team of researchers from Wake Forest University, the National Institutes of Health and other institutions has discovered a previously undetected chemical process within the oxygen-carrying molecule hemoglobin that could have far-reaching implications for the treatment of cardiovascular diseases.
