RNA interference can be used to silence genes selectively - potential for Huntington's disease therapy

Howard Hughes Medical Institute researchers have designed tiny RNA molecules that shut off the gene that causes Huntington's disease without damaging that gene's healthy counterpart, which maintains the health and vitality of neurons.

New approach for surveying phosphorylation

Scientists have developed a new approach for surveying phosphorylation, a process that is regulated by critical cell signaling pathways and regulates several key cellular signaling events.

New alternative to biopsy detects subtle changes in cancer cells

A drop of blood or a chunk of tissue smaller than the period at the end of this sentence may one day be all that is necessary to diagnose cancers and assess their response to treatment, say researchers at the Stanford University School of Medicine.

Thymosin beta-4 protein prompts damaged heart cells to repair themselves after a heart attack

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found.

Early administration of HIV antiretroviral therapy improves survival

The first antiretroviral treatments appeared in 1996. Since then, new and better drugs have been discovered that have almost turned AIDS into a chronic disease.

Research points to a new approach to treating type 1 diabetes

Scientists at Burnham Institute for Medical Research (Burnham) and the University of California San Diego (UC San Diego) School of Medicine have demonstrated in mice that transplanted pancreatic precursor cells are protected from the immune system when encapsulated in polytetrafluorethylene (PTFE).

Discovery of key decision-point at which cells with broken DNA repair themselves or die

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Researchers explain process by which cells 'hide' potentially dangerous DNA segments

The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end.

Scientists discover the secrets of NF-kappaB

A study published in Science examines a key player in conditions such as cancer, inflammatory bowel disease, rheumatoid arthritis and asthma and has shown that cells use a sophisticated communication system to coordinate responses to infection and maintain inflammation in the body.

Researchers reveal how immune cells can be harnessed to target melanoma

Researchers at the Babraham Institute and the University of Catanzaro "Magna Graecia", Italy, co-ordinating an international network of scientists and clinicians from Europe, the USA and Japan, have identified new mechanisms through which the immune system recognises and responds to tumours like melanomas.

For cancer cells, genetics alone is poor indicator for drug response

In certain respects, cells are less like machines and more like people.

Discovery of gene that protects against leukemia

Researchers have identified a gene that controls the rapid production and differentiation of the stem cells that produce all blood cell types -- a discovery that could eventually open the door to more streamlined treatments for leukemia and other blood cancers, in which blood cells proliferate out of control.

Novel method for comprehensive proteome analysis

Investigators at Burnham Institute for Medical Research (Burnham) have deciphered a large percentage of the total protein complement (proteome) in Schizosaccharomyces pombe (S. pombe) fission yeast.

New common pathway in neurodegenerative disease is a possible door to a point of no return

A just-out study suggests that what keeps chronic nervous system diseases such as Alzheimer's, Huntington's and ALS going - until they overcome the internal protective mechanisms a body can throw at them - may largely come down to poor conversational skills.

Important discover in cancer metastases

If cancer cells lack a certain protein, it could be much easier for them to penetrate healthy body tissue, the first step towards forming metastases.

Seroquel XR supplemental NDA recommended for approval

The U.S. Food and Drug Administration (FDA) Psychopharmacologic Drugs Advisory Committee (PDAC) conducted a review of the safety and efficacy of supplemental new drug applications (sNDA) for Seroquel XR (quetiapine fumarate) extended-release tablets proposed for the treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD).

Experimental drug lowers PSA levels

A new multi-center study shows that an experimental drug lowers prostate specific antigen (PSA) levels – a marker for tumor growth – in men with advanced prostate cancer for whom traditional treatment options have failed.

DNA origami rectangle made with 'bottom-up' construction approach

The construction of complex man-made objects--a car, for example, or even a pizza--almost invariably entails what are known as "top-down" processes, in which the structure and order of the thing being built is imposed from the outside (say, by an automobile assembly line, or the hands of the pizza maker).

Cancer vaccines receive orphan drug designation for advanced head and neck cancer

Two experimental vaccines from the University of Maryland, Baltimore (UMB) recently received a federal orphan drug designation for advanced head and neck cancer, according to a company official.

Too much dietary protein and fat may lead to insulin resistance

A clue about the blood chemistry of obese people who develop insulin resistance, a precursor to diabetes, has been confirmed in animal studies at the Duke University Medical Center.
