Titan Helps Researchers Suck Mystery Out of Cell's 'Vacuum Cleaners'In the fight against cancer, cancer cells often find ways to fight back. One means is by stocking the cell membrane with proteins that pump foreign substances—including anticancer drugs—out of the cell. This trait can result in multidrug resistance that undermines the effectiveness of cancer treatment. To combat this defense mechanism, scientists are turning to supercomputers and molecular dynamics to better understand the function of a membrane transport protein called P-glycoprotein, or Pgp. ... Recently, a team led by computational biophysicist Emad Tajkhorshid from the University of Illinois at Urbana-Champaign (UIUC) uncovered new details about Pgp that could help the drug discovery community..
Supercomputer Visualization Shows 1.2 Microseconds in the Life of a 4-Million-Atom HIV CapsidWhile some researchers look for drugs to treat HIV, other scientists delve deep into the virus itself for answers on how it causes infections. Using two supercomputers, University of Illinois research scientist Juan R. Perilla and late physics professor Klaus Schulten simulated 1.2 microseconds of the life of the HIV capsid, the structure that contains the virus's genetic material. The simulation, which took two years to complete, gives us a view of the virus on a molecular level and provides us with insight into how HIV senses its environment and becomes infective..
A cure for HIV takes a step closer after supercomputers reveal how the virus movesA brief glimpse into how HIV travels through the body has been simulated for the first time on supercomputers in the US. For two years, multiple supercomputers at the University of Illinois modelled the behaviour of 64 million atoms to capture 1.2 microseconds of the life of an HIV capsid, a protein cage that transports the HIV virus to the nucleus of a human cell. The capsid simulation was performed on the Department of Energy's Titan supercomputer, while analysis was made using the Blue Waters supercomputer at the National Center for Supercomputing Applications at the university..
Massive Simulation Shows HIV Capsid Interacting with its EnvironmentIt took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle. The findings are reported in the journal Nature Communications. "We are learning the details of the HIV capsid system, not just the structure but also how it changes its environment and responds to its environment," said University of Illinois research scientist Juan R. Perilla, who led the study with U. of I. physics professor Klaus Schulten. Such details could help scientists find new ways to defeat the virus, Perilla said..
Rock Stars of HPC: James PhillipsRecipient of a Gordon Bell Award in 2002, James Phillips has been a full-time research programmer for almost 20 years. Since 1998, he has been the lead developer of NAMD, a parallel molecular dynamics code designed for high-performance simulation of large biomolecular systems that scales beyond 200,000 cores, and is undoubtedly a Rock Star of HPC. ... InsideHPC: That advice led you to Professor Klaus Schulten – what impact did he have on your career? When Schulten came here from Germany he had a couple of grad students and a home-built parallel computer that they used to run the first simulation of a membrane back in early 1990s. He was very much dedicated to the idea that we can use parallel computing to do science and he largely dedicated his life to running this place. In fact he rarely slept – I remember at one point I was working on something and I sent him an email at 3am to try and impress him, and he wrote back..
First atomic-scale view of interaction between HIV capsid and host protein cyclophilin AA new study offers the first atomic-scale view of an interaction between the HIV capsid - the protein coat that shepherds HIV into the nucleus of human cells - and a host protein known as cyclophilin A. This interaction is key to HIV infection, researchers say. A paper describing the research appears in the journal Nature Communications. ... "We have known for some time that cyclophilin A plays a role in HIV infection," said University of Illinois physics professor Klaus Schulten, who led the new study with postdoctoral researcher Juan R. Perilla and University of Pittsburgh professor Peijun Zhang and postdoctoral researcher Chuang Liu..

Computing a Cure for HIV: 9 Ways Supercomputers Help Scientists Understand and Treat the VirusThe tendency of HIV to mutate and resist drugs has made it particularly difficult to eradicate. Some treatments have shown progress in slowing or even stopping the progress of the virus, but no cure or vaccine has been discovered that can truly stamp out the disease. In the last decade scientists have begun using a new weapon in the fight against HIV: supercomputers. ... Among the researchers using supercomputers to study HIV is Klaus Schulten, the keynote speaker at the 2014 International Supercomputing Conference in Leipzig, Germany. Schulten, a professor of physics at the University of Illinois at Urbana-Champaign, invented the Nanoscale Molecular Dynamics (NAMD) software program, one of the most widely used tools for understanding diseases at a molecular level..
