The developmental on-switch

German researchers have demonstrated for the first time why the molecular cocktail responsible for generating stem cells works. Sox2 and Oct4 are proteins whose effect on cells resembles that of an eraser: ...

The TALE of new tools to study gene regulation

In nearly every organism's genome, scattered between genes that encode proteins, long regulatory regions stretch across expanses of DNA. Understanding what role these so-called enhancer regions play in controlling the activation ...

Life's tiniest architects pinpointed

If a genome is the blueprint for life, then the chief architects are tiny slices of genetic material that orchestrate how we are assembled and function, Yale School of Medicine researchers report Feb. 21 in the journal Developmental Ce ...

Making and breaking heterochromatin

To fit the two-meter long DNA molecule into a cell nucleus that is only a few thousandths of a millimetre in size, long sections of the DNA must be strongly compacted. Epigenetic marks maintain these sections, ...

Functional genomics gets tiny

A little more than a decade ago, researchers discovered an ancient mechanism that cells use to silence genes. Like a dimmer switch turning down a light, RNA interference (RNAi) dials down gene activity in ...
