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.

Discovery of novel mechanisms that might causally link type-2 diabetes to Alzheimer's disease

A recent study by Mount Sinai faculty suggests that a gene associated with onset of type-2 diabetes also decreases in Alzheimer's disease dementia cases.

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.

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.

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

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

Test predicts who will develop end-stage renal disease

Measuring kidney function by assessing two different factors-glomerular filtration rate (GFR) and urinary albumin levels-helps determine which patients with chronic kidney disease (CKD) will develop end-stage renal disease (ESRD), according to a study appearing in the May 2009 issue of the Journal of the American Society Nephrology (JASN).

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.

Research finds active brown fat in adult humans

Researchers at the Joslin Diabetes Center have demonstrated that adult humans still have a type of "good" fat previously believed to be present only in babies and children.

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.

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.

Trial of new biologic agent to treat psoriatic arthritis

Psoriatic arthritis affects about 11 percent of patients with psoriasis.

8 Apr 2009

Discovery of mechanism of cell type-specific signaling in tumor development

Mayo Clinic researchers have discovered the mechanisms behind two key checkpoints in cell growth and development - factors that may ultimately allow investigators to benchmark progression of tumor cells or stop them from further development.

Diets high in fat and protein are most dangerous

It's basically a given that diets loaded with fat can lead to considerable health problems.

Growth factor TGF-beta helps maintain health of retinal blood vessels

Scientists at Schepens Eye Research Institute have found that the growth factor known as TGF-beta is essential to the health of blood vessels in the retina and that blocking it can cause retinal dysfunction.

Genetic risk factors play role in autoantibody-negative rheumatoid arthritis

During the past few years, several new genetic risk factors for rheumatoid arthritis (RA) have been identified.

New nanostructured biosensors

Research and industry are increasingly exploiting the potential of aptamers.

Antibiotics could treat cystic fibrosis, other genetic diseases

By modifying the properties of the common antibiotic gentamicin, researchers at the Technion-Israel Institute of Technology have developed what could become an effective treatment for many human genetic diseases, including cystic fibrosis (CF), Duchenne muscular dystrophy, Usher Syndrome and numerous cancers.
