Findings could help develop new approaches to treat depression and memory loss in the elderly

Scientists have known for some time that exercise induces neurogenesis in a specific brain region, the hippocampus. However, until this study, the underlying mechanism was not fully understood.

Study: Blocking certain enzymes in cell may prevent cancer cell division and growth

Blocking certain enzymes in the cell may prevent cancer cell division and growth, according to new findings from researchers at the Graduate School of Biomedical Sciences at the Icahn School of Medicine at Mount Sinai.

Mechanism of tumor suppressor p53 inactivation described

Cancer cells are a problem for the body because they multiply recklessly, refuse to die and blithely metastasize to set up shop in places where they don’t belong. One protein that keeps healthy cells from behaving this way is a tumor suppressor named p53. This protein stops potentially precancerous cells from dividing and induces suicide in those that are damaged beyond repair. Not surprisingly, p53’s critical function is disrupted in most cancers.

Individuals with MEN1 are at increased risk of developing neuroendocrine tumors

A mutation in a protein called menin causes a hereditary cancer syndrome called MEN1 (multiple endocrine neoplasia type 1).

Nanogels to attack lupus: an interview with Dr Look and Dr Fahmy, Yale University

Nanogels are synthetic particles that can be used for drug delivery. They are approximately 100 nm to 200 nm in diameter, and are made from safe, biocompatible materials: a gel-like interior and a lipid exterior.

Study identifies potential drug targets that interfere with cancer metabolism

A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer.

Shc plays key role in activating and controlling Erk

A protein which is intimately involved in cancer-promoting cell signaling also keeps a key component of the signaling pathway tied down and inactive, a team led by scientists from The University of Texas MD Anderson Cancer Center reports this week in Nature Structural Molecular Biology.

New research reveals how acute stress primes brain for improved performance

Overworked and stressed out? Look on the bright side. Some stress is good for you. "You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley.

Research opens new avenue for treatment of melanoma

For the first time, scientists have demonstrated the mechanism of action of gossypin, a naturally-occurring substance found in fruits and vegetables, as a treatment for melanoma, which causes the majority of deaths from skin cancer.

Mammalian target of rapamycin (mTOR) pathway: an interview with Dr. Paul Mischel, Ludwig Institute for Cancer Research

The mammalian target of rapamycin, mTOR is a central integrator of the cell that coordinates growth factor receptor signaling with energy and nutrient status to control a wide array of activities, including the regulation of cellular proliferation and survival.

Insulin resistance can increase risk of breast cancer in women

In a previous work the authors analyzed a large cohort of breast cancer patients to look whether an association existed between the risk of tumor development and the presence of the metabolic syndrome — a syndrome that predisposes to cardiovascular and other diseases, which is characterized by abdominal obesity, high levels of triglycerides and low concentrations of HDL cholesterol, increased blood pressure and insulin resistance

Modifiable lifestyle factors may prevent progression of Barrett's-related esophageal cancer

An estimated 20 million Americans have chronic heartburn. About 2 million of these people have Barrett's esophagus, a precancerous condition that affects the tube that carries food from the mouth to the stomach.

AACR recognizes scientists whose contributions to cancer field have extraordinary impact

Five University of California, San Diego scientists and professors are among the first class of the Fellows of the American Association for Cancer Research Academy, created to recognize researchers whose scientific contributions have propelled significant innovation and progress against cancer.

Exposure to multiple estrogen-mimicking chemicals distorts hormone action

For years, scientists have been concerned about chemicals in the environment that mimic the estrogens found in the body. In study after study, researchers have found links between these "xenoestrogens" and such problems as decreased sperm viability, ovarian dysfunction, neurodevelopmental deficits and obesity.

New study associates commonly used diabetes drugs with pancreatic cancer risk

ndividuals who had taken a type of drug commonly used to treat Type 2 diabetes showed abnormalities in the pancreas, including cell proliferation, that may be associated with an increased risk of neuroendocrine tumors, according to a new study by researchers from UCLA and the University of Florida.

Scientists discover novel compounds that can lead to new strategies for treating diseases

Using a broad spectrum of analytical tools, scientists from the Florida campus of The Scripps Research Institute have uncovered a class of novel compounds that can alter cell signaling activity, resulting in a variety of responses including a strong anti-inflammatory effect.

Multipotent stem cells in deer antler may have regenerative uses in veterinary medicine

A team of researchers in Seoul, Korea have reported finding evidence that deer antlers - unique in that they regenerate annually - contain multipotent stem cells that could be useful for tissue regeneration in veterinary medicine.

Swine study shows that moderate exercise can affect ovarian cells

A short walk around the barn might improve the future fertility of Yorkshire gilts. According to research presented by Samantha Kaminski, a graduate student at North Dakota State University, swine fetuses showed significant ovarian development after their mothers exercised.
