The movement of proteins within the nucleus can occur by diffusion ... The new ways in which cell biology can now be carried out are approaching the mesoscopic scale 15 and surprises are likely ...

After all, there must have been a time when the ancestor of eukaryotes did not possess a nucleus; the question is whether that cell possessed a mitochondrion or not.

A team of researchers at Åbo Akademi University in Finland made a surprising discovery. They found that Talin-1, a protein ...

A kidney cancer cell nucleus is studded with aberrant nuclear speckles (orange). Normal healthy cells tend to have the speckles clustered toward the middle. Image credit: Kate Alexander (Cold Spring ...

Nucleus, cell membrane ... I cut and sell meat over the counter to the public. Biology was probably my favourite subject funnily enough. I've always been fascinated with bodies, with animals ...

Nuclear pore complexes are the guardians of the human genome that is packaged into the nucleus of all cells. They form selective channels through the envelope of the nucleus and connect its ...

The nuclear envelope is a regulated membrane barrier that separates the nucleus from the cytosol in eukaryotes. Although the NE is often depicted as a static barrier, new research has identified ...

In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is commonly known to be responsible for protein trafficking and secretion. In ...
