Cancer researchers find evolutionary change that occurred in a key developmental signalling pathway

Cancer researchers at the University of Helsinki, in trying to find a novel tumor suppressor gene, instead found an important evolutionary change that occurred in a key developmental signalling pathway. The finding suggests a potential mechanism for evolution of complex intercellular signalling pathways.

Mad cow proteins also maintain stem cells

What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain themselves.

Eosinophilic esophagitis gene discovery

Researchers at Cincinnati Children's Hospital Medical Center have discovered the first gene associated with eosinophilic esophagitis, one of a number of eosinophil-related diseases in which the body produces abnormally large amounts of white blood cells that can lead to allergy related illnesses.

miRNA emerge as a class of gene regulators

Scientists have discovered that a wide variety of different cancers actually share something in common - a molecular "signature" made up of tiny bits of genetic material called microRNA (miRNA) that target key cancer genes and promote malignant growth.

Abraham Lincoln may have suffered from movement disorder

Researchers at Johns Hopkins and the University of Minnesota have discovered a gene mutation in the descendants of Abraham Lincoln's grandparents that suggests the Civil War president himself might have also suffered from a disease that destroys nerve cells in the cerebellum-- the part of the brain that controls movement.

Fatty acids such as those found in corn oil turn on genes that stimulate tumor growth

Omega-6 fatty acids--such as those found in corn oil--caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center.
