Scientists identify specific pathways behind breast cell's transformation into cancer

Although it's widely accepted that inflammation is a critical underlying factor in a range of diseases, including the progression of cancer, little is known about its role when normal cells become tumor cells. Now, scientists from the Florida campus of The Scripps Research Institute have shed new light on exactly how the activation of a pair of inflammatory signaling pathways leads to the transformation of normal breast cells to cancer cells.

University of Georgia researcher to develop first Chagas vaccine for pets

Chagas disease is the single most common cause of congestive heart failure and sudden death in the world. The devastating parasitic infection affects millions of people throughout Central and South America. But as global travel increases, it's becoming a greater threat in the United States and Europe as well.

Biological scaffold for heart valves can be freeze-dried for later use

The biological scaffold that gives structure to a heart valve after its cellular material has been removed can be freeze-dried and stored for later use as a tissue-engineered replacement valve to treat a failing heart, as described in an article in Tissue Engineering, Part C: Methods, a peer-reviewed journal from Mary Ann Liebert, Inc..

Scientists identify single prion protein that causes neuronal death

Scientists from the Florida campus of The Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion species.

Scientists use metabolomics to discover DMS linked with neuropathic pain

Millions of people worldwide suffer from a type of chronic pain called neuropathic pain, which is triggered by nerve damage. Precisely how this pain persists has been a mystery, and current treatments are largely ineffective. But a team led by scientists from The Scripps Research Institute, using a new approach known as metabolomics, has now discovered a major clue: dimethylsphingosine (DMS), a small-molecule byproduct of cellular membranes in the nervous system.

Nurture plays an important role in cerebral cortex

Our visual systems allow us to appreciate the beauty of the world, but they were mainly evolved to help us survive, by avoiding predators and capturing prey. Central to that task is the ability to instantly determine whether objects are moving, and the direction of that movement.

Research on neuron interaction could lead to potential treatment for addiction

Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.

Hormone that burns energy discovered

Boston scientists have found a hormone that is secreted by muscles during exercise and boosts the amount of energy the body burns. This hormone – irisin – could be the first step in development of new drugs for obesity, diabetes, and other diseases feel researchers. A Boston startup company, Ember Therapeutics, has already licensed the technology and is working to develop a form of the hormone that could be used as a drug that would mimic some of the benefits of exercise.

Scientists identify importance of novel protein-regulating mechanism

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open up opportunities to develop new types of drugs for diseases such as cancer.

Harvard SEAS, BASF to co-host symposium on pharmaceutical nanoformulations

From targeted cancer chemotherapy to the guarantee of successful organ transplants, the 21st century may prove to be the age of big ideas in medicine. The drugs themselves, though, will be miniscule. Experts in chemistry, applied physics, materials science, and pharmaceutical science are gathering this week for the BASF Advanced Research Initiative at Harvard University's symposium on pharmaceutical nanoformulations.
