Many leukemias are caused by loss of the enzyme Pten. Some anti-leukemia treatments work by inhibiting another enzyme called Shp2. Researchers have now found that mice lacking both of these enzymes ...

An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced ...

Enzymes are biomolecules that perform specialized functions, such as the assembly or degradation of small molecules. The small size of enzymes (tens of nanometres) previously limited their study to ...

New science out of Stanford University could one day lead to revolutionary new drugs for the treatment of alcohol addiction. A study, to be published Friday in Science, puts forward a new theory on ...

The study may help explain a phenomenon noticed by researchers and primary care physicians alike: adults in their 40s may eat less and exercise more, but not see the results in weight loss. The ...

Aside from illuminating one possible path for life’s beginnings, the achievement is likely to yield a powerful tool for evolving new and useful molecules. “When I start to tell people about this, they ...

DURHAM, N.C. -- Researchers at Duke University Medical Center have provided the first direct evidence in mice for the role of an enzyme that specifically controls the production of serotonin in the ...

Many types of leukemia are caused by loss of enzymes such as Pten, which normally keeps cell growth in check, or conversely, the over-activation of enzymes that normally enhance cell proliferation, ...
