All the excitement about nanotechnology comes down to this: Structures of materials at the scale of billionths of a meter take on unusual properties. Technologists often focus on the happier among these newfound capabilities, but new research by an interdisciplinary team of scientists at Brown University finds that nanoparticles of nickel activate a cellular pathway that contributes to cancer in human lung cells. http://phys.org/news233315082.html Nanotechnology Tue, 23 Aug 2011 10:44:52 EST news233315082 A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells. Their findings, to be published in the January 1 issue of the journal Nature, explain how advanced cancer cells usurp components of the host innate immune system to generate an inflammatory microenvironment hospitable for the metastatic spread of lung cancer. The discovery could lead to a therapy to limit metastasis of this most common lethal form of cancer. http://phys.org/news149951977.html Medicine & Health Wed, 31 Dec 2008 13:19:37 EST news149951977
