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 ...

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 ...

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 ...

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 ...

Ageing researchers have long been searching for so-called biomarkers of ageing, which allow predictions about health and lifespan of organisms. Varnesh Tiku, a scientist in the department of Director ...
