The subsequent events in nucleolar RNA synthesis are discussed in light of the morphologic and biochemical effects of actinomycin D on the nucleolus. The Journal of Cell Biology (JCB) is a ...

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 ...

This figure illustrates the tripartite architecture of the nucleolus.

THE nucleolus was first figured in 1781 as a spot in the centre of a round or oval body (the nucleus) in epithelial cells of the eel. Since then it has been described in the nuclei of almost every ...

“That could really help us unlock the structure-to-function relationship and figure out what is the role of the third compartment.” 10 things you need to know direct to your inbox every weekday.

A single scaffold protein is critical for the formation of part of the nucleolus, giving clues to how the nucleolus evolved around 300 million years ago.

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 ...
