Combination of temsirolimus and bryostatin appears safe and active in metastatic kidney cancer

Fox Chase Cancer Center investigators report that a two-drug blockade of mTOR signaling appears safe in metastatic kidney cancer in a phase I trial. Early data suggests that a combination of temsirolimus and bryostatin may be active in patients with rare forms of renal cell cancer, which are less likely to respond to other targeted therapies.

Genetic profiling reveals genes active in the earliest brain circuit construction

Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo.

Discovery of biochemical signals that help immune cells remember how to fight infection

Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins.

Revealed - the culprit gene in hair loss!

Researchers at the Division of Mammalian Development at the National Institute of Genetics in Mishima, say the gene appears to determine cyclical hair loss in mice and they suspect it may also be the culprit in hair loss, or alopecia, in people.

Cohesin protein disrupts gene function in Cornelia deLange syndrome

An international team of scientists studying a rare genetic disease discovered that a bundle of proteins with the long-established function of keeping chromosomes together also plays an important role in regulating genes in humans.

Activated stem cells in damaged lungs could be first step toward cancer

Stem cells that respond after a severe injury in the lungs of mice may be a source of rapidly dividing cells that lead to lung cancer, according to a team of American and British researchers.

New therapy shows potential for treating Duchenne muscular dystrophy

Researchers at the University of Minnesota Medical School have discovered a new therapy that shows potential to treat people with Duchenne muscular dystrophy, a fatal disease and the most common form of muscular dystrophy in children.

Abraxane prolongs survival in metastatic breast cancer

Research from the Northwestern University Feinberg School of Medicine has found that a less toxic, solvent-free chemotherapy drug more effectively prevents the progression of metastatic breast cancer and has fewer side effects than a commonly used solvent-based drug.

Discovery of biological markers that may indicate poor breast cancer prognosis

A team of researchers has found an association between breast cancer survival and two proteins that, when present in the blood in high levels, are indicators of inflammation.

The evolution of gene regulation: How microbial neighbors settle differences

Even microbes are governed by the principle of supply and demand - at least at the genetic level. Not all of their gene products, the blueprints for proteins, are required at all times. That means most of their genes only become active when they are needed, as is the case in higher organisms.

New mouse model provides insight into human neuronal diseases

Neurosensory diseases are difficult to model in mice because their symptoms are complex and diverse. The genetic causes identified are often lethal when transferred to a mouse.

Discovery of genetic link between periodontitis and heart attack

The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. Although a genetic link seemed likely, until now its existence was uncertain. Now, for the first time, scientists have discovered a genetic relationship between the two conditions, a researcher told the annual conference of the European Society of Human Genetics today (Monday 25 May).

Scientists cure mice of muscle disease that causes a Floppy Baby Syndrome

In a world first, West Australian scientists have cured mice of a devastating muscle disease that causes a Floppy Baby Syndrome - a breakthrough that could ultimately help thousands of families across the globe.

Heart protein saves muscle

A heart muscle protein can replace its missing skeletal muscle counterpart to give mice with myopathy a long and active life, show Nowak et al. The findings will be published online on Monday, May 25, 2009 and will appear in the June 1, 2009 print issue of the Journal of Cell Biology.

Extreme caffeinated soft drink diet leaves woman with serious health issues

Reports in the media of a New Zealand woman's extreme Red Bull diet where her weight plummeted from 105kg to 60kg by drinking 10 to 14 cans of the 'energy' drink each day say she has been left with serious health issues.

Scientists map sequence mutations of the 2009 H1N1 influenza A virus

In just two weeks from the time the first patient virus samples were made available, Singapore scientists report an evolutionary analysis of a critical protein produced by the 2009 H1N1 influenza A virus strain.

Simple genetic test determines transplant drug tolerance

A simple genetic test can determine a kidney transplant patient's tolerance for a potent anti-rejection medication, according to an upcoming study in the Journal of the American Society Nephrology (JASN). The test could allow doctors to individualize each patient's dose, optimizing the drug's benefits and minimizing its side effects.

HER2/neu protein predicts development of invasive breast cancer in women with ductal carcinoma in situ

Women with ductal carcinoma in situ (DCIS) who exhibit an overexpression of the protein HER2/neu have a six-fold increase in risk of invasive breast cancer, according to a new study from the University of Pennsylvania School of Medicine.
