Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

1,000 strains of mice that feature the genetic diversity of the world population

Mice that are part of the Collaborative Cross project at Oak Ridge National Laboratory are helping scientists around the world learn more about possible causes of drug abuse, diabetes, sleep disorders, stress and pain, kidney disease and a number of other conditions that affect millions of people.

'Mighty mice' made mightier

The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect.

St. Jude discovers factors that accelerate resistance to Gleevec targeted therapy in lymphoblastic leukemia

Results of a study by investigators at St. Jude Children's Research Hospital provide strong evidence for why the drug imatinib (Gleevec), which has revolutionized the treatment of chronic myelogenous leukemia (CML), is often unable to prevent relapse of a particularly aggressive form of acute lymphoblastic leukemia (ALL).

Discovery may lead to fast and cheap method of making vaccines

Researchers may be able to tinker with a single amino acid of an enzyme that helps viruses multiply to render them harmless, according to molecular biologists who say the discovery could pave the way for a fast and cheap method of making vaccines.

New discovery helps explain the mechanics of hearing

A 30-year scientific debate about how specialized cells in the inner ear amplify sound in mammals appears to have been settled more in favor of bouncing cell bodies rather than vibrating, hair-like cilia, according to St. Jude investigators.

Vioxx side-effects explained

Vioxx and related pain medications were taken off the market in 2004 because they caused dangerous heart problems in some people.
