Although heart disease still represents the leading cause of death worldwide, genomic studies have increasingly helped scientists zero in on a number of likely causes. For example, mitral valve prolapse (MVP), which affects 2-3% of the population, has not been previously associated with a specific genetic mutation even though it was seen to occur frequently in certain families.

Scientists at Ohio State University say they have discovered how bacteria use toxins to interrupt the immune response. The researchers say it's important to understand how the toxins work because they are key to enabling bacteria to cause disease.

Researchers at the National Institutes of Health say they used atomic level images to show how the neuropeptide hormone neurotensin might activate its receptors. Their description reportedly is the first of its kind for a neuropeptide-binding G protein-coupled receptor (GPCR), a class of molecules involved in a wide range of disorders and the target of many drugs.

Scientists at Rice University and University of Texas MD Anderson Cancer Center have developed a way to mimic the conditions under which cancer tumors grow in bones. By placing cancer cells in a three-dimensional scaffold and subjecting them to the forces that push, pull, and continually flow through the body, the researchers are better able to test the efficiency of cancer-fighting drugs.

Raising hopes for a simple, noninvasive, inexpensive, and easily repeatable test for pancreatic cancer, scientists at Barts Cancer Institute, Queen Mary University, have developed a three-protein biomarker panel that can screen urine samples to identify pancreatic cancer when it is still in its early stages.
