As evidence mounts that the body's normally protective inflammation response can drive some precancerous tissues to become fully malignant, UCSF scientists report discovering an apparent trigger to…

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation…

Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique. Since then he has used RNAi…

When cells become cancerous, they also become 100 times more likely to genetically mutate than regular cells, researchers have found. The findings may explain why cells in a tumor have so many…

A special cocoa made to retain naturally occurring compounds called flavonols may have the potential to help maintain healthy brain function and chart the course for future research that could lead…

An international team of researchers from 19 countries has identified one gene and a previously unidentified region of another chromosome as the location of another gene that may contribute to a…

Imagine a cancer treatment tailored to the cells in a patient’s body, each person receiving a unique treatment program. This is what Natural Sciences and Engineering Research Council grantee Thomas…

From roundworm to human, most cells in an animal’s body ultimately come from stem cells. When one of these versatile, unspecialized cells divides, the resulting “daughter” cell receives instructions…

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time…

Quickly now, which is a higher risk that you will get a disease: 1 in 100; 1 in 1,000; or 1 in 10? Choosing the correct answer depends on a person's numeracy – the ability to grasp and use math and…
