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

In 2009, Jonathan Weissman was hunting for a new way to spy on what happens inside a cell. In particular, the molecular cell biologist wanted to know what proteins are produced at any given moment. So ...

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

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

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 ...

Biomedical engineers at Duke University have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, ...

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.

Randal Halfmann at the Stowers Institute for Medical Research in Kansas City is hoping to treat diseases including cancer and Alzheimer's by influencing how cells make life-or-death decisions. In ...

Proteins are a bit like lights in your house. They have a job to do, and getting them to do it involves switching them on and off with other proteins or molecules. But it’s much easier to flip the ...

A new Dartmouth study opens new avenues for understanding—and potentially manipulating—how cells decide to live or die.
