Cell nuclei harbor factories that transcribe genes

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

RNA molecule behind behavior changes cued by environment

Quick changes in behavior – in worms, at least – can be triggered by a unique form of the molecule RNA acting within the nucleus of a cell, UC San Francisco researchers have discovered.

Preventing the spread of repression

Scientists at the Friedrich Miescher Institute for Biomedical Research have identified a novel and unexpected regulatory activity of RNA at the edge of inactive chromosomal regions. In their publication in Nature Structural ...

Human Argonaute proteins: To slice or not to slice?

What makes one Argonaute a slicer and another one not? Human Argonaute proteins are key players in the gene regulation process known as RNA interference, RNAi. Professor Joshua-Tor's group of Cold Spring Harbor Laboratory ...
