A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is ...

Septins are a conserved family of GTP-binding proteins that assemble into filamentous structures, earning them recognition as the fourth component of the cytoskeleton alongside actin, microtubules and ...

Caspases are a family of proteolytic enzymes that play a central role in apoptosis, the regulated process of programmed cell death essential for development, homeostasis and the clearance of damaged ...

Researchers at UC Merced used fruit flies to uncover a cellular process common to many organisms that could dramatically impact the understanding of cancer and aging. Department of Molecular and Cell ...

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells ...

A new study from Whitehead Institute Member Jonathan Weissman reveals how cells may activate a compensation system that can, in some cases, reduce the effects of potentially harmful genetic mutations.
