The size of a cell's nucleolus may reveal how long that cell, or even the organism it belongs to, will live. Over the past few years, researchers have been piecing together an unexpected link between ...

Scientists have identified a new RNA molecule that may play a key role in improving survival in cancer patients.

The nucleolus—a conspicuous but obscure organelle within the cell nucleus—is normally too compact to be studied in detail. Researchers at Case Western Reserve University just learned how to simplify ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect underlying the machinery of protein manufacture has long ...

Biologists discovered that a scaffolding protein called TCOF1 is responsible for the formation of a biomolecular condensate called the fibrillar center, which forms within the cell nucleolus. Inside ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were ...

At most, 10 people in the world are known to have BPTA. Five of them participated in the current study, and they were found to share virtually the same mutation in the gene for the HMGB1 protein. It ...
