Scientists produce tiny molecular 'binder' that may help develop more efficient drugs

Developing new drugs is a highly costly and time-consuming process. Of 20 candidates, 19 are normally rejected because they don't work or have unwanted side effects. Now a research team led by Professor Lars Baltzer at Uppsala University has produced a tiny molecular "binder" that has the potential to change this landscape radically.

Study may help develop novel ways to combat lipotoxic cardiomyopathy, related heart disease

A team led by Rolf Bodmer, Ph.D. at Sanford-Burnham Medical Research Institute recently unraveled an alternative pathway to lipotoxic cardiomyopathy in fruit flies - a genetic mechanism that occurs independently of a diet high in fat.

Researchers find kidney-specific gene defects may increase risk of heart failure

Scientists have identified the first DNA sequence variant common in the population that is not only associated with an increased risk of heart failure, but appears to play a role in causing it.

New discovery has brought dream of transforming measles virus against cancer

When most people in the developed world think of measles, what comes to mind is only a dim memory of a vaccination at a pediatrician's office. But while childhood vaccination has virtually eliminated measles from North America and much of Europe, researchers remain interested in the virus.

Scientists introduce DNA directly into cell nucleus using protein nanodisks

One of the challenges of gene therapy - a set of methodologies aimed at treating several nucleic acid diseases - is to assure that this material arrives directly to the nucleus of the cell without losing a substantial amount along the way and without producing any undesired side effects. With this aim, scientists experiment with the use of different types of vectors, molecules capable of transporting genetic material to the correct place.

Researchers describe crucial initial steps taken by measles virus attachment proteins with receptors

Mayo Clinic researchers have shown that proteins on the surface of a cell twist a viral protein into position, allowing the virus to start infection and cause disease, all in a movement as graceful as a ballroom dance. The findings appear in the current online issue of Nature Structural & Molecular Biology.

U-M lab ranks No. 1 in protein structure and function prediction in scientific competition

The University of Michigan Health System took top honors in the Critical Assessment of Techniques for Protein Structure Prediction, a biennial scientific competition to test protein structure and function prediction methods developed by laboratories all over the world.

Choosing between EGFR therapeutic options in metastatic colorectal cancer

Colorectal cancer (CRC) is the third most common cancer in men and women in the USA, with a new diagnosis made every 3.5 minutes and an associated death every 9 minutes.

Researchers study molecular mechanisms in early stages of IPN virus infection

Infectious pancreatic necrosis is a serious disease that leads to enormous losses in the salmon industry each year. The virus that causes the disease, IPN, is very prevalent in farmed salmon and trout in Norway. The virus attacks a wide diversity of hosts and has been found to occur in many different fish species, in addition to shellfish and molluscs.

CFTR protein regulates inflammation and cell death in emphysema, chronic lung diseases

A team of Johns Hopkins Children's Center researchers has discovered that a protein involved in cystic fibrosis also regulates inflammation and cell death in emphysema and may be responsible for other chronic lung diseases.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

UCLA findings could lead to enhanced health supplements, progress on Parkinson's

The discovery by UCLA biochemists of a new method for preventing oxidation in the essential fatty acids of cell membranes could lead to a new class of more effective nutritional supplements and potentially help combat neurodegenerative disorders such as Parkinson's disease and perhaps Alzheimer's.

MRS imaging technique may help diagnose chronic traumatic encephalopathy

In a study of ex-pro athletes, researchers found that a specialized imaging technique called magnetic resonance spectroscopy (MRS) may help diagnose chronic traumatic encephalopathy (CTE), a disorder caused by repetitive head trauma that currently can only be definitively diagnosed at autopsy. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Rush University enrolls first U.S. patient in international clinical trial for melanoma

Rush University Medical Center has just enrolled the first U.S. patient in an international clinical trial testing a novel drug to treat certain kinds of melanoma, a deadly skin cancer that in its advanced stages currently has few effective treatments.

NIH awards $6.7M to establish Membrane Protein Structural Biology Consortium

Dr. Michael G. Malkowski, Hauptman-Woodward senior research scientist, has received a $6.7 million grant from the National Institutes of Health in support of his work to establish the Membrane Protein Structural Biology Consortium (mpsbc.org) as one of nine centers in the United States responsible for determining membrane protein structures within a larger NIH biology-based initiative.

Study sheds light on poorly understood aspect of interaction of HIV with natural killer cells

Natural killer cells are major weapons in the body's immune system. They keep the body healthy by knocking off tumors and cells infected with viruses, bombarding them with tiny lethal pellets. But natural killer cells are powerless against HIV, a fact that has bedeviled science for over 20 years.

Study refocuses on rare group of neutralizing antibodies against HIV

Although people infected with HIV produce many antibodies against the protein encapsulating the virus, most of these antibodies are strangely ineffective at fighting the disease. A new study suggests why some of the most common of these antibodies don't work: they target the protein in a form it takes after the virus has already invaded the cell, when it's too late, report researchers at Children's Hospital Boston and their colleagues.

Researchers document novel form of splicing in nerve cell cytoplasm

Cells have their own version of the cut-and-paste editing function called splicing. Researchers at the University of Pennsylvania School of Medicine have documented a novel form of splicing in the cytoplasm of a nerve cell, which dictates a special form of a potassium channel protein in the outer membrane.

New direct labeling system for oocytes, embryos

Researchers from the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB), in collaboration with researchers from the Institute of Microelectronics of Barcelona (IMB-CNM) of the Spanish National Research Council (CSIC), have developed an identification system for oocytes and embryos in which each can be individually tagged using silicone barcodes.
