Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.

Gene marker may improve odds of stem cell therapies for disease

A single tumor-suppressor gene may provide a unique marker for senescence in Mesenchymal stem cells (MSCs) in vitro, while also playing a role in moving MSCs into senescence, researchers at the Human Health Foundation and the Sbarro Institute for Cancer Research and Molecular Medicine report.

Biologist finds plant polymerases IV and V are really variants of polymerase II

It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.
