A new insight into cell signals that control cancer growth and migration could help in the search for effective anti-cancer drugs. A McGill-led study reveals key biochemical processes that advance our ...

HOUSTON, Nov. 19, 2010 – University of Houston (UH) physicists are using complex computer simulations to illuminate the workings of a crucial protein that, when malfunctioning, may cause Alzheimer's ...

COLUMBUS, Ohio -- When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly ...

Everything a cell does, from dividing in two to migrating to a different part of the body, is controlled by enzymes that chemically modify other proteins in the cell. Researchers at Princeton ...

Mathematical modeling helps researchers to understand how enzymes in the body work to ensure normal functioning. The models also can show how genetic mutations alter the enzymes' behavior in ways that ...

As people grow older, the same brain chemistry that once supported sharp thinking and stable mood can quietly start to work ...

Enzymes help with specific functions that are vital to the operation and overall health of the body. They help speed up chemical reactions in the human body. They are essential for respiration, ...

Liver enzymes can fluctuate due to factors like hormonal changes or reactions to medications. Fluctuations are often temporary, but long-term changes may indicate a condition that requires medical ...
