New research has advanced understanding of how the nucleolus is assembled through a process called liquid-liquid phase separation and has identified a protein that plays key role Researchers have ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists have learned that besides building a cell's protein factories, ...

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 ...

The nucleolus is a well-known cellular structure that is easily visible under a light microscope. This nuclear structure is known as the site of ribosome production. In a recent study, researchers at ...

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 ...

Striking nucleolar lesions occur in cultured cells after exposure to supranormal temperatures. These lesions appear at 42°C and consist of a loss of the granular ribonucleoprotein (RNP) component and ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...

An essential component of living cells, the nucleolus underwent a major evolutionary shift around 300m years ago. Scientists have solved an age-old mystery in biology by discovering a protein found in ...

Inside all living cells, loosely formed assemblies known as biomolecular condensates perform many critical functions. However, it is not well understood how proteins and other biomolecules come ...

A nucleolar protein, nucleostemin, is now implicated in the control of stem and cancer cell proliferation. Nucleostemin may modulate p53 function through shuttling between the nucleolus and the ...
