Loss of tumor suppressor SPOP releases cancer potential of SRC-3 Mutations in a protein called SPOP (speckle-type POZ protein) disarm it, allowing another protein called steroid receptor coactivator-3 (SRC-3) to encourage the proliferation and spread of prostate cancer cells, said researchers led by those at Baylor College of Medicine in a report that appears online in Proceedings of the National Academy of Sciences.

Researchers show stem cell fate depends on 'grip' The field of regenerative medicine holds great promise, propelled by greater understanding of how stem cells differentiate themselves into many of the body's different cell types. But clinical applications in the field have been slow to materialize, partially owing to difficulties in replicating the conditions these cells naturally experience.

The elderly inhabitants of Ikaria, the Greek island, boast the highest rates of longevity in the World, and many scientists turn to them when looking to discover the 'secrets of a longer life'.

Some brain cells are better virus fighters Viruses often spread through the brain in patchwork patterns, infecting some cells but missing others. New research at Washington University School of Medicine in St. Louis helps explain why. The scientists showed that natural immune defenses that resist viral infection are turned on in some brain cells but switched off in others.
