DNA Organization Offers Clues for Advancing Stem Cell Therapy

Scientists at the University of California, Riverside, have discovered how adult stem cells retain their regenerative power. The researchers demonstrate in a paper published in the journal Genes & Development that these cells rely on a group of helper proteins called histone chaperones — organizers or guides known to help package our two-meter-long genome when cells need to divide or switch on specific genes.

Understanding the Complex Architecture of the Minor Spliceosome

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome continuously separates the coding and non-coding regions of our genes – and it's doing this even as you read these lines.
