Pancreatic cancer cells' growth are fueled by metabolic pathway, scientists find

Dana-Farber Cancer Institute scientists and colleagues have discovered that pancreatic cancer cells' growth and spread are fueled by an unusual metabolic pathway that someday might be blocked with targeted drugs to control the deadly cancer.

SDF-1 turns on autophagy that helps cells stay in place and focused on making bone

A signaling molecule that helps stem cells survive in the naturally low-oxygen environment inside the bone marrow may hold clues to helping the cells survive when the going gets worse with age and disease, researchers report.

Inhibiting JNK enzyme protects against ischemic/reperfusion injury

Using two different compounds they developed, scientists from the Florida campus of The Scripps Research Institute (TSRI) have been able to show in animal models that inhibiting a specific enzyme protects heart cells and surrounding tissue against serious damage from heart attacks.

SOD1 enzyme protects cells by regulating cell energy and metabolism

Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells against damage from free radicals. Now, researchers at the Johns Hopkins Bloomberg School of Public Health have discovered that SOD1 protects cells by regulating cell energy and metabolism. The results of their research were published January 17, 2013, in the journal Cell.

Macular pigment screening: an interview with Jaquie Finn, Product Line Manager at Elektron Technology

AMD is the leading cause of vision loss in anyone over 50 and globally in 2010 it was estimated to cost $340 billion to treat AMD. The costs are set to spiral over the next 20 years and really over burden the healthcare system unless people start to take preventative action.

Study highlights role of Protein S in maintenance of healthy retina

Researchers at the Hebrew University of Jerusalem, in collaboration with researchers at the Salk Institute in California, have found for the first time that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular and nervous systems, as well as in various cancers.

Scientists identify novel mechanism by which ketogenic diet could delay effects of aging

Scientists at the Gladstone Institutes have identified a novel mechanism by which a type of low-carb, low-calorie diet-called a "ketogenic diet"-could delay the effects of aging. This fundamental discovery reveals how such a diet could slow the aging process and may one day allow scientists to better treat or prevent age-related diseases, including heart disease, Alzheimer's disease and many forms of cancer.

Carnosic acid promotes eye health

Herbs widely used throughout history in Asian and early European cultures have received renewed attention by Western medicine in recent years. Scientists are now isolating the active compounds in many medicinal herbs and documenting their antioxidant and anti-inflammatory activities. In a study published in the journal Investigative Ophthalmology & Visual Science, Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) report that carnosic acid, a component of the herb rosemary, promotes eye health.
