Study shows how Notch gene and PRC2 protein complex work together to cause T-ALL

A new study published in the journal Nature Medicine by NYU Cancer Institute researchers, shows how the cancer causing gene Notch, in combination with a mutated Polycomb Repressive Complex 2 (PRC2) protein complex, work together to cause T- cell acute lymphoblastic leukemia.

Lack of iron early in life can affect brain's physical structure

Iron is a popular topic in health news. Doctors prescribe it for medical reasons, and it's available over the counter as a dietary supplement. And while it's known that too little iron can result in cognitive problems, it's also known that too much promotes neurodegenerative diseases. Now, researchers at UCLA have found that in addition to causing cognitive problems, a lack of iron early in life can affect the brain's physical structure as well.

Grapes offer dramatic protection against age-related macular degeneration

Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects.

Female fish choose well fed males over undernourished ones: Study

At least in some species being well fed as a kid makes a male more attractive to the opposite sex. Researchers from the Australian National University (ANU) have discovered female mosquitofish (Gambusia holbrooki) prefer males with a strong nutritional upbringing. The preference is there even when the males are otherwise identical to previously undernourished fish. These mosquitofish were introduced to Australia in an attempt to control mosquitoes.

Low-glycemic-load diet reduces C-reactive protein associated with chronic disease

Among overweight and obese adults, a diet rich in slowly digested carbohydrates, such as whole grains, legumes and other high-fiber foods, significantly reduces markers of inflammation associated with chronic disease, according to a new study by Fred Hutchinson Cancer Research Center.

Scientists discover how sense of touch is wired in skin and nervous system

Neuroscientists at the Johns Hopkins University School of Medicine have discovered how the sense of touch is wired in the skin and nervous system. The new findings, published Dec. 22 in Cell, open new doors for understanding how the brain collects and processes information from hairy skin.

Insight into brain mechanism that limits rewarding impact of cocaine

Research published by Cell Press in the January 12 issue of the journal Neuron provides fascinating insight into a newly discovered brain mechanism that limits the rewarding impact of cocaine. The study describes protective delayed mechanism that turns off the genes that support the development of addiction-related behaviors.

First details of genetic alterations that fuel early T-cell precursor ALL

Researchers have discovered that a subtype of leukemia characterized by a poor prognosis is fueled by mutations in pathways distinctly different from a seemingly similar leukemia associated with a much better outcome. The findings from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP) highlight a possible new strategy for treating patients with this more aggressive cancer.

Excess salt stimulates production of adrenalin and causes hypertension

A review article by researchers at Boston University School of Medicine (BUSM) debunks the widely-believed concept that hypertension, or high blood pressure, is the result of excess salt causing an increased blood volume, exerting extra pressure on the arteries. Published online in the Journal of Hypertension, the study demonstrates that excess salt stimulates the sympathetic nervous system to produce adrenalin, causing artery constriction and hypertension.

Elevated ISG15 pathway may provide therapeutic targets for breast cancer

Interferon-stimulated gene 15 (ISG15), a ubiquitin like protein, is highly elevated in a variety of cancers including breast cancer. How the elevated ISG15 pathway contributes to tumorigenic phenotypes remains unclear and is the subject of a study published in the January 2012 issue of Experimental Biology and Medicine.

New imaging agent shows promise in detecting signs of AD

Scientists are reporting development and initial laboratory tests of an imaging agent that shows promise for detecting the tell-tale signs of Alzheimer's disease (AD) in the brain - signs that now can't confirm a diagnosis until after patients have died.
