Biologists have long suspected that aging is not just a slow, inevitable fraying of our cells but a process governed by ...

Cells are not immortal, and that is a good thing. After a certain number of divisions, many human cells stop multiplying for ...

Most proteins in human cells are not randomly distributed but are concentrated in membraneless proteinaceous droplets known as biomolecular condensates 1. Dozens of different types of condensates have ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps ...

Scientists at NYU Langone discovered that blocking a key protein that shields cancer cells from a natural stress-driven death process can dramatically slow lung tumor growth.

Thought too hard to do, a new platform evolved proteins in mammalian cells, which could help researchers design drugs that work better in humans. “There are many, many examples, both published and ...

It's known as biology's central dogma: All living organisms' genetic information is stored in DNA, which is transcribed into RNA, which is translated into proteins that perform nearly all essential ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a ...

A protein notorious for its role in Alzheimer’s disease may hold the key to supercharging the aging immune system, according to new research. Scientists have found that a byproduct of amyloid-beta ...

Scientists have made a major breakthrough in understanding how fat cells grow in size, in response to accommodating larger droplets of fat. The findings unlock a new path in tackling obesity, by ...
