Study reveals how galectin-3 carbohydrate-binding protein promotes angiogenesis

A new study describes how a carbohydrate-binding protein, galectin-3, promotes angiogenesis, the growth of new blood vessels. Targeting the protein, scientists identified two approaches that significantly reduced angiogenesis in mice. These discoveries, published online August 16 in The Journal of Experimental Medicine, may lead to novel treatments for diseases caused by excessive angiogenesis, including age-related macular degeneration, cancer, and diabetes.

Copper-free version of click chemistry crafted to create biomolecular probes

For the first time, the widely used molecular synthesis technique known as click chemistry has been safely applied to a living organism. Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have crafted a unique copper-free version of click chemistry to create biomolecular probes for in vivo studies of live mice. Conventional click chemistry reactions require a copper catalyst that is toxic to cells and organisms.

Recent developments at Burnham Institute for Medical Research

New antibiotics for methicillin-resistant Staphylococcus aureus (MRSA) and other pesky bacteria. Andrei Osterman and collaborators have used comparisons of bacterial genomes to identify new targets for antibiotics and produced first-generation chemical inhibitors of a class of bacterial enzymes, called NadDs (nicotinate mononucleotide adenylyltransferases).

First-ever glimpse of the cell-wall structure in three dimensions

The bacterial cell wall that is the target of potent antibiotics such as penicillin is actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium like a belt around a person, according to research conducted by scientists at the California Institute of Technology (Caltech).

Ashwell receptor plays key role in reducing coagulation abnormalities during infection and sepsis

In research that solves the longest-standing mystery in glycobiology - a field that studies complex sugar chains called glycans - researchers at the University of California, San Diego School of Medicine have discovered that a molecule in the liver of all animals, called the Ashwell receptor, is critical in helping the body fight off the abnormal and lethal blood clotting caused by bacterial infection.

Emergence of a human-adapted H5 virus is a clear threat to public health worldwide

The H5N1 avian influenza virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. So far, its spread to humans has been limited, with 177 documented severe infections, and nearly 100 deaths in Indonesia, Vietnam, Thailand, Cambodia, China, Iraq, and Turkey as of March 14, 2006, according to the World Health Organization.

Molecular link between high fat diets and type 2 diabetes established

Howard Hughes Medical Institute researchers have discovered a molecular link between a high-fat, Western-style diet, and the onset of type 2 diabetes. In studies in mice, the scientists showed that a high-fat diet disrupts insulin production, resulting in the classic signs of type 2 diabetes.

Gut antibody could prove to be a promising drug target for Crohn's disease

A collaboration led by the Burnham Institute for Medical Research has found that an antibody which binds to an unusual sugar molecule residing in the gut halts the inflammation seen in Crohn's disease and other intestinal inflammations. The antibody could prove to be a promising drug target for these common chronic intestinal disorders.
