New Role Discovered for Molecule Important in Development of Pancreas, Penn Study Finds
For years researchers have been searching for a way to treat diabetics by reactivating their insulin-producing beta cells, to no avail. Now, they may be one step closer. A protein, whose role in pancreatic development has long been recognized, has been discovered to play an additional and previously unknown regulatory role in the development of... view more...

Alzheimer's: New findings resolve long dispute about how the disease might kill brain cells
For a decade, Alzheimer's disease researchers have been entrenched in debate about one of the mechanisms believed to be responsible for brain cell death and memory loss in the illness. view more (2009-04-16)
Scientists demonstrate means of reducing Alzheimer's-like plaques in fly brain
Neuroscientists at Cold Spring Harbor Laboratory (CSHL) are part of a collaboration that has succeeded in demonstrating that overexpression of an enzyme in the brain can reduce telltale deposits causally linked with Alzheimer's disease. view more (2008-07-16)
Botched production of insulin molecule may lead to diabetes
Picture a pretzel factory production line, with conveyer belts carrying the dough, formed into unbaked pretzels, down to the oven to be cooked. Now imagine what would happen if pretzel dough started to overflow the mixer and oozed as a blob onto the conveyor, misshapen, and sticking fast to the dough of the other fully formed, unbaked pretzels. view more (2007-10-02)
Scientists uncover indicator that warns leukemia is progressing to more dangerous form
Scientists at the Moores Cancer Center at the University of California, San Diego, Stanford University School of Medicine and other centers have identified a mechanism by which a chronic form of leukemia can progress into a deadlier stage of the disease. view more (2009-02-17)
Researchers identify cancer-causing gene in many colon cancers
Demonstrating that despite the large number of cancer-causing genes already identified, many more remain to be found, scientists at Dana-Farber Cancer Institute have linked a previously unsuspected gene, CDK8, to colon cancer. view more (2008-09-15)
Hybrid molecules show promise for exploring, treating Alzheimer's
One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties. view more (2009-11-05)
Blocking immune cell action increases Alzheimer's-associated protein deposits
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. view more (2007-03-28)
Omega-3 fatty acids inhibit growth of liver cancer cells
Two new studies by a University of Pittsburgh research team suggest that omega-3 fatty acids-substances that are found in high concentrations in fish oils and certain seeds and nuts-significantly inhibit the growth of liver cancer cells. view more (2006-04-03)
Substance in tree bark could lead to new lung-cancer treatment
Researchers at UT Southwestern Medical Center have determined how a substance derived from the bark of the South American lapacho tree kills certain kinds of cancer cells, findings that also suggest a novel treatment for the most common type of lung cancer. view more (2007-06-26)
Medication plus beta-blocker helps prevent shocks from implantable cardioverter defibrillator
Use of the medication amiodarone in combination with a beta-blocker is effective in preventing shocks that can occur from an implantable cardioverter defibrillator. view more (2006-01-11)
Researchers find gene that spurs development of the epididymis
Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization. view more (2007-06-28)
Suspected cause of type 1 diabetes caught
Scientists at Washington University School of Medicine in St. Louis working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes. view more (2008-05-12)
Stem cell research uncovers mechanism for type 2 diabetes
Taking clues from their stem cell research, investigators at the University of California San Diego (UC San Diego) and Burnham Institute for Medical Research (Burnham) have discovered that a signaling pathway involved in normal pancreatic development is also associated with type 2 diabetes. view more (2009-02-13)
Gene variants linked with increased risk of death among heart patients treated with beta-blockers
Patients with certain gene variants who were prescribed beta-blocker drugs after acute coronary syndrome (ACS) had an increased risk of death over the next three years, according to a study in the September 28 issue of JAMA. view more (2005-09-28)
MRI May Help Physicians Diagnose, Stage and Treat Diabetes
Noninvasive imaging (MRI) may aid physicians in the early diagnosis, staging and treatment of diabetes, according to a study performed at Massachusetts General Hospital and Harvard Medical School in Boston, MA. view more (2009-08-06)
Early trigger for type-1 diabetes found in mice, Stanford scientists report
Scientists at the Stanford University School of Medicine are shedding light on how type-1 diabetes begins. view more (2008-08-27)
Jefferson Researchers Find Potential Biomarker for Heart Failure
Signs of heart failure may be in the blood. Cardiac researchers at Jefferson Medical College have found an enzyme in the blood that could be a potential marker for heart failure. view more (2005-08-22)
UCLA scientists identify how immune cells may help predict Alzheimer's risk
What if you could test your risk for Alzheimer's disease much like your cholesterol levels - through a simple blood test? view more (2009-07-14)
Beta-carotene assoc. with higher risk of some cancers in women smokers but not nonsmokers
A new study of French women has found that high beta-carotene intake-through a combination of diet or supplementation-is associated with a higher risk of tobacco-related cancers in smokers, but the risk of these cancers decreases with increasing beta-carotene intake in nonsmokers. view more (2005-09-21)
