A Northwestern Medicine study has revealed a previously unknown connection between two fundamental cellular processes, ...

There is a huge amount of DNA in most human cells, and that DNA has to be carefully compacted and organized so that it will fit into a cell’s nucleus, while the crucial parts of it remain accessible ...

Chromatin remodeling plays a vital role in gene regulation, affecting how DNA is accessed. Disruptions in this process can also lead to cancer and other diseases. To better understand how chromatin ...

DNA inside human cells is not free-floating. Instead, it is tightly wrapped around small protein units forming a long chain, with DNA looping around each unit before moving on to the next. This ...

Movie 1: Movement of single nucleosomes in living human cells. The movie shows nucleosome fluctuations in euchromatin (left), where gene expression is active, and in heterochromatin (right), where ...

Researchers from Northwestern University have stumbled upon a previously unobserved function of a protein found in the cell nuclei of all flora and fauna. In addition to exporting materials out of the ...
