Researchers report sleep-like states in brainless marine animals, suggesting rest began as a basic cellular repair mechanism.

The human genome is contained within the nucleus of cells. The genome is well protected, but many things can cause DNA damage, including aging, some drugs, and environmental factors like UV rays or ...

Sermorelin, a synthetic analog of growth hormone–releasing hormone (GHRH 1–29), has long attracted scientific interest due to its structural fidelity to the endogenous GHRH fragment responsible for in ...

Kidney fibrosis, a common endpoint of chronic kidney disease (CKD), is strongly linked to aging, with cellular senescence emerging as a key driver in its pathogenesis. This overview synthesizes ...

Much like humans generate mountains of garbage, our cells are constantly discarding proteins that are damaged or no longer needed. The cellular waste disposal system called the proteasome is best ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

Like jewels in a vault, our precious genetic material is stored in the nucleus of a cell--sequestered away from potentially damaging cellular components and toxins so that no harm can come to it. Yet ...
