• 06:00 Researchers show how far South American cities moved in quake

• 06:00 The soluble factor IFN-beta represses tumor growth

  Read the story at EurekAlert
  Tumors that grow to a certain size need to form new blood vessels if they are to continue to grow and spread to other sites. Although the molecules and signaling pathways that control this new blood vessel growth are potential therapeutic targets, they have not been completely defined. However, researchers have now identified the soluble factor IFN-beta as a natural inhibitor of tumor blood vessel growth that limits tumor growth in mice.
