University of Pennsylvania researchers have developed a powerful new investigative tool to reveal how proteins work inside living cells. A technique that enables quick, precise and minimally ...

The average human cell contains roughly 10,000 different proteins. Existing as several to millions of copies in each cell, proteins mediate all manner of tasks, including chemical transformations, ...

Cells that are about to die send a signal to an executioner protein, but sometimes, those cells can fight back and regenerate ...

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many ...

Researchers found that the body’s natural recycling system, the lysosome, plays a vital role in removing the protein that drives premature aging. When this system breaks down, aging speeds up. By ...

A new Brazilian study has revealed the key role of the protein periostin and stellate pancreatic cells in allowing pancreatic cancer to infiltrate nerves and spread early, increasing the risk of ...

The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing ...
