Finding has implications for treatment of wide range of diseases Johns Hopkins scientists investigating chemical modifications across the genomes of adult mice have discovered that DNA modifications in non-dividing brain cells, thought to be inherently stable, instead underwent large-scale dynamic changes as a result of stimulated brain activity. Their report, in the October issue of Nature Neuroscience, has major implications for treating psychiatric diseases, neurodegenerative disorders,...

Results suggest novel approach to developing targeted cancer therapies Scientists at Fox Chase Cancer Center have discovered a new mechanism used by cells in the body to turn on silenced genes. This process is critical in preventing the development of cancer"”suggesting the possibility of new therapies that might target the specific changes underlying the disease. The findings will be published online in the journal Cell on June 30, 2011. The process investigated by Alfonso Bellacosa,...

The DNA contained within each of our cells is exactly the same, yet different types of cells "“ skin cells, heart cells, brain cells "“ perform very different functions. The ultimate fate of these cells is encoded not just in the DNA, but in a specific pattern of chemical modifications that overlay the DNA structure. These modifications, or epigenetic markers as they are called, are stably carried in our genomes -- except for at times when the cells change their fate, such as what...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
