Massachusetts General Hospital (MGH) Cancer Center researchers have discovered a previously unknown feature of common tumor cells – massive overexpression of certain DNA sequences that do not code for proteins. These DNA sequences – called satellite repeats – have been studied for their role in chromosomal structure but previously were not suspected of having a role in cancer. The report will appear in the journal Science and is receiving early online release.

An old pinworm medicine is a new lead in the search for compounds that block a signaling pathway implicated in colon cancer. The findings, reported by Vanderbilt University Medical Center researchers in the November issue of Nature Chemical Biology, suggest a fresh approach for developing therapeutics that target the pathway.

New animal research has identified factors, such as the stress response and immune system, that may play important roles in depression. Scientists have also found that the regulation of nerve cell signals influences depression in animals, and that new drug combinations may more effectively treat it. The findings were presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
