A simplified version of an artificial cell produces functional proteins and even sorts them. http://phys.org/news282828507.html Nanotechnology Mon, 18 Mar 2013 12:28:36 EST news282828507 Researchers from Johns Hopkins and Northwestern universities have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases. http://phys.org/news269239164.html Nanotechnology Fri, 12 Oct 2012 05:39:31 EST news269239164 (Phys.org)—Heidelberg molecular biologists have gained new insights into the function of so-called molecular chaperones in protein synthesis. The team headed by Dr. Günter Kramer and Prof. Dr. Bernd Bukau of the DKFZ-ZMBH Alliance, a research association between Heidelberg University's Center for Molecular Biology (ZMBH) and the German Cancer Research Center (DKFZ), was able to demonstrate how a molecular chaperone in bacterial cells can influence the formation of the three-dimensional structure of new proteins. http://phys.org/news265123625.html Biology Sat, 25 Aug 2012 14:27:23 EST news265123625 Universitat Autonoma de Barcelona researchers developed a new vehicle to release proteins with therapeutic effects. The vehicles are known as "bacteria inclusion bodies", stable insoluble nanoparticles which are found normally in recombinant bacteria. Even though these inclusion bodies traditionally have been an obstacle in the industrial production of soluble enzymes and biodrugs, they were recently recognised to have large amounts of functional proteins with direct values in industrial and biomedical applications. http://phys.org/news251121796.html Nanotechnology Fri, 16 Mar 2012 13:04:21 EST news251121796 Copper-iodide nanoparticles have long-lasting antiviral activity against the 2009 pandemic H1N1 influenza virus, according to a paper in the February issue of the journal Applied and Environmental Microbiology. http://phys.org/news248540200.html Nanotechnology Wed, 15 Feb 2012 15:30:03 EST news248540200 When researchers at the Buck Institute dialed back activity of a specific mRNA translation factor in adult nematode worms they saw an unexpected genome-wide response that effectively increased activity in specific stress response genes that could help explain why the worms lived 40 percent longer under this condition. The study, appearing in the July 6, 2011 edition of Cell Metabolism, highlights the importance of mRNA translation in the aging process. mRNA translation occurs after genetic messages have been transcribed in cells, when the encoded messages of genes are actually translated into functional proteins. http://phys.org/news229087691.html Biology Tue, 05 Jul 2011 12:28:24 EST news229087691 (PhysOrg.com) -- Researchers from the California Institute of Technology (Caltech) and the University of California at San Diego (UCSD) have brought together UCSD theoretical modeling and Caltech experimental data to show just how amino-acid chains might fold up into unique, three-dimensional functional proteins. http://phys.org/news154633865.html Chemistry Mon, 23 Feb 2009 17:51:40 EST news154633865
