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 ...

Wound healing: 'See-saw' switch sends cells on the march

Many genes are transcribed into messenger RNA (mRNA) molecules that provide instructions for protein synthesis. Other genes encode regulatory RNAs known as 'microRNAs', which can block protein translation by binding to specific ...

Getting under the shell of the turtle genome

Scientists have decoded the genome of the western painted turtle (Chrysemys picta bellii) , one of the most abundant turtles on Earth, finding clues to their longevity and ability to survive without oxygen during long winters ...

Sugar influences the onset of flowering, study finds

(Phys.org)—A plant can reproduce successfully only if it flowers at the appropriate time. Therefore, a complex network of photoreceptors and other proteins has evolved to monitor environmental conditions such as light and ...
