The primary function of the nucleolus is as the site of ribosome-subunit biogenesis in eukaryotic cells. The initial ribosomal RNA (rRNA) precursor is transcribed by RNA polymerase I and is ...

In a new study published in the journal Molecular Cell, researchers from the Spanish National Cancer Research Center (CNIO) investigated how this nucleolar stress can affect the rest of the cell, ...

One clue might be links between proteins rich in a specific amino acid and stress in an organelle called a nucleolus in the ...

Seven members of the Yale faculty who have made important contributions across a range of fields, including neuroscience, ...

There’s a fitness center, swimming pool, hot tub, tennis court, and golf course on property but, honestly, the horses at this working cattle ranch are the nucleolus of the operation. Join a ...

The nucleolus is the cellular component where ribosomes are synthesized. In recent decades it has been observed that one of its functions is also to detect stress situations in the cell ...

Google has a tool that shows 3D models of different animals, dinos, and more so you can teach children or just have fun — ...

The difference in nuclear structure between neurones of adult male and female cats rests on the degree of development of a second body, which is much smaller than the nucleolus." In the early ...

The neuromuscular junction (NMJ, yellow) and myotendinous junctions (MTJ, green arrows) are shown. Nuclei (white, Hoechst) and nucleolus (cyan, a-Fibrillarin) are also revealed. Dotted lines suggest ...

The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterizing materials, cells and ...
