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 ...

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

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, ...

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

When it comes to neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and certain forms of dementia, ...

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

Johns Hopkins researchers identified a new target for treating Alzheimer’s disease by focusing on a protein that produces tiny amounts of hydrogen sulfide in healthy brain cells.

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 ...

Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive ...
