Studying epigenetic regulation at the single-molecule level

If one imagines the genome as an instruction manual for the functioning of a cell, every page of this manual is covered with annotations, highlights, and bookmarks. The role of some of these marks remains mysterious—do ...

Key regulator of cell growth deciphered

The mTOR protein plays a central role in cell growth, proliferation and survival. Its activity varies according to the availability of nutrients and some growth factors, including hormones. This protein is implicated in several ...

Hairpin turn: Micro-RNA plays role in wood formation

For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...
