    Reuters ^ | Dec 17, 2009 | Julie Steenhuysen
    CHICAGO (Reuters) – U.S. researchers have discovered antiviral proteins in cells that naturally fight off influenza infections, a finding that may lead to better ways to make vaccines and protect people against the flu. They said a family of genes act as cell sentries that guard cells from an invading influenza virus, the team reported on Thursday in the journal Cell. "This prevents the virus from even getting into the cell," said Stephen Elledge of Harvard Medical School and a Howard Hughes Investigator at Brigham & Women's Hospital. "It is out there fighting the flu all of the time," Elledge...

    Water in Biology ^ | March 3, 2009 | Philip Ball
    In my previous post I mentioned work by Pablo Debenedetti on ‘toy models’ of water. The places to look are: Buldyrev et al., PNAS 104, 20177 (2007) (here) for the solvation thermodynamics of ‘spherical’ water; and Patel et al., Biophys. J. 93, 4116 (2007) (here) and J. Chem. Phys. 128, 175102 (2008) (here) for water-explicit lattice models of proteins. And in discussing recent work on the mechanism of urea-induced protein denaturation, I neglected to mention Bruce Berne’s PNAS paper from late last year with Ruhong Zhou, Dave Thirumalai and Lan Hua (105, 16928; paper here). That paper on MD simulations...

    Nuclear magnetic resonance spies the atomic details of proteins in action. Scientists have used NMR to look at proteins including TTHA1718 (above) inside living cells.Nature The atomic structures of proteins at work inside cells can now be probed, thanks to researchers who have modified a technique that is already widely used in labs and for medical imaging.When a protein is inside a cell — rather than in a test tube — it behaves subtly differently because it may be interacting with other biological molecules that float around in the cellular space. Because proteins are hard to work with unless they...

    Journal of Chemical Physics ^ | December 4 2008 | Vijay Pande
    ... We present a novel computational approach for describing the formation of oligomeric assemblies at experimental concentrations and timescales. We propose an extension to the Markovian state model approach, where one includes low concentration oligomeric states analytically. This allows simulation on long timescales (seconds timescale) and at arbitrarily low concentrations (e.g., the micromolar concentrations found in experiments), while still using an all-atom model for protein and solvent. As a proof of concept, we apply this methodology to the oligomerization of an Abeta peptide fragment (Abeta 21–43). Abeta oligomers are now widely recognized as the primary neurotoxic structures leading to Alzheimer's...

    The PandeGroup has all been very excited about the great turnout of FAH donors over the last few weeks, allowing FAH to go over a petaflop. The PS3's have been cranking out some very useful scientific results due to the new scientific software present in v1.2. The PS3's are so fast, we've been looking at the results sometimes 2x to 3x a day (instead of a couple times a month). If all goes well, we're hoping to write up these results soon (maybe a few weeks) for peer reviewed publication. It's also interesting to think about what we want to...

    We live in the age of the prion, says New York writer DT Max in his introduction to this neat little medical whodunit. The claim sounds worthy of a car advert. You are never alone with a prion. That sort of thing. In fact, the prion is a strange, non-living infectious agent whose behaviour was widely disputed until US medical researcher Stanley Prusiner confirmed its existence in a series of elegant experiments that won him a Nobel Prize for physiology in 1997. Now, most scientists accept prions are responsible for a range of modern curses: mad cow disease, the fatal...

    Pharmed food crop approved for growth despite controversy.Rice modified to express proteins often found in breast milk will be planted in Kansas. It's certainly not the first crop designed to produce pharmaceutical proteins given the go-ahead in the United States or elsewhere (see 'Turning plants into protein factories'). But this is among the first food crops containing genes that produce human proteins to gain approval for large-scale planting. Many other pharmaceutical genetically-modified (GM) crops are grown indoors or in inedible plants such as tobacco. The rice strains, made by Ventria Bioscience in Sacramento, California, produce lysozyme, lactoferrin and human serum...
  • Researchers Discover 'sticky' Proteins Fuse Adult Stem Cells To Cardiac Muscle, Repairing Hearts

    Cardiologists are increasingly using adult stem cells in clinical trials to repair hearts following heart attacks, but no one has understood how the therapy actually works. Now, in animal experiments, researchers at The University of Texas M. D. Anderson Cancer Center have deconstructed the process, describing how the stem cells fuse with heart muscle cells to create new cells that repopulate the ailing organ. In a paper posted at Online First of the journal Circulation Research, investigators found that this fusion is only possible if two cell adhesion proteins that stick to each other like Velcro are available to attach...

    NEW YORK: A newly designed porous membrane, so thin that it's invisible edge-on, might revolutionise the way doctors and scientists manipulate objects as small as molecules. The 50-atom thick filter can withstand surprisingly high pressures and may be a key to better separation of blood proteins for dialysis patients, speeding ion exchange in fuel cells and purifying air and water at the nanoscopic level. "It's amazing, we have a material as thin as some of the molecules it's sorting, and riddled with holes - but it can withstand enough pressure to make real-world nano-filtering a practical reality," said Christopher Striemer...

    PhysOrg.com ^ | November 30, 2006
    Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to dice and splice genetic material to create unique and varied proteins. The scientists say the findings, made in mice, help explain a key wonder of human biology: how the same genes found in every cell of an individual’s body can produce different proteins in different tissues and organs. These varied proteins, in turn, dictate the function of each tissue or organ. The findings also may offer insight into a number of diseases, including cancer, in which the genetic process --...

    New Scientist Tech ^ | 14 June 2006 | Tom Simonite
    A computer system that automatically tracks the movements of proteins within a living cell has been developed by a team of biologists and computer vision experts. It could save researchers the hours often spent analysing microscope images by hand, to determine the way a cell works. The system, called CellTracker, automatically analyses a series of still digital images captured through a microscope. Doug Kell at Manchester University in UK, the lead biologist involved with the project, believes the system could dramatically speed up studies of cells' function. "Most people just fix cells [in one place], which kills their metabolism," he...

    Background Cancer is a major medical problem in modern societies. However, the incidence of this disease in non-human primates is very low. To study whether genetic differences between human and chimpanzee could contribute to their distinct cancer susceptibility, we have examined in the chimpanzee genome the orthologous genes of a set of 333 human cancer genes. Results This analysis has revealed that all examined human cancer genes are present in chimpanzee, contain intact open reading frames and show a high degree of conservation between both species. However, detailed analysis of this set of genes has shown some differences in genes...

    Charles Darwin, the 19th century geologist who wrote the treatise 'The Origin of Species, by means of Natural Selection' defined evolution as "descent with modification". Darwin hypothesized that all forms of life descended from a common ancestor, branching out over time into various unique life forms, due primarily to a process called natural selection. However, the fossil record shows that all of the major animal groups (phyla) appeared fully formed about 540 million years ago, and virtually no transitional life forms have been discovered which suggest that they evolved from earlier forms. This sudden eruption of multiple, complex organisms is...

In two papers appearing in the Sept. 22 issue of the journal Nature, Dr. Rama Ranganathan, associate professor of pharmacology, and his colleagues detail a new method for creating artificial proteins based only on information they derived from analyzing certain characteristics that individual natural proteins have in common with each other.

    SYDNEY (AFP) - Australian scientists have discovered pineapple molecules can act as powerful anti-cancer agents and said the research could lead to a new class of cancer-fighting drugs. Scientists at the Queensland Institute of Medical Research (QIMR) said their work centred on two molecules from bromelaine, an extract derived from crushed pineapple stems that is used to tenderise meat, clarify beers and tan hides. One of the molecules, CCZ, stimulates the body's immune system to target and kill cancer cells, the other, CCS, blocks a protein called Ras, which is defective in 30 percent of all cancers. QIMR researcher Tracey...

    New research into primitive protective proteins from the immune systems of sharks could lead to more versatile drugs to battle diseases such as cancer and dangerous bacterial infections and to robust diagnostic kits that could easily leave the lab, an area of intense research following the anthrax attacks of 2001. In a study published Thursday online by the journal Science, researchers at The Scripps Institute in La Jolla, CA, and the University of Maryland at Baltimore determined that the structure of the primitive antibody that marks a difference between the immune systems of sharks and mammals is unusually simple.

    Scientists are reporting that, for the first time, they have made an artificial prion, or misfolded protein, that can, by itself, produce a deadly infectious disease in mice and may help explain the roots of mad cow disease. The findings, being reported on Friday in the journal Science, are strong evidence for the so-called "protein only hypothesis," the controversial idea that a protein, acting alone without the help of DNA or RNA, can cause certain kinds of infectious diseases. The concept was introduced in 1982 by Dr. Stanley Prusiner, a neurology professor at the University of California in San Francisco,...

    n an advance that could lead to three-dimensional pictures of proteins and other molecules, scientists have developed a magnetic resonance imaging technique that can detect a single electron. "There's lots of things this will be useful for," said Dr. Daniel Rugar, manager of nanoscale studies at I.B.M.'s Almaden Research Center in San Jose, Calif., and leader of the research team, which is reporting the findings today in the journal Nature. "There are thousands of proteins in the body whose structures are not known." It is largely proteins' shapes that enable them to carry out the essential functions of the body,...

    Herbal alternatives are under attack. Download and print flyers. The flyers urge consumers to tell their congressmen and senators to attend the JUNE 17th Herbal Alternatives Congressional Briefing to learn the truth about herbs & health. It is critical that Congress attends this briefing because: HERBAL ALTERNATIVES ARE UNDER ATTACK. News headlines misinform and mislead decision makers. Products you depend on for your health could soon be banned. MANY CAPITOL HILL STAFFERS AND POLICY MAKERS DO NOT UNDERSTAND NATURAL HEALTH INDUSTRY ISSUES. Since DSHEA was passed in 1994, about 50% of Congressmen and Senators and 80% of Congressional aides have...

    Scientists have discovered that monkey cells have innate protection against infection with the human AIDS virus, a clue that may help explain why some people are susceptible to certain viral infections while others are not. The finding, reported in today's issue of the journal Nature, offers one of the first concrete examples of what researchers call an intracellular system of innate immunity and may open the door to the development of new antiviral therapies, the scientists said. The monkeys were protected from the virus by a mechanism that resides within cells and that is independent of the antibodies and white...

    NASA nanometer breakthrough uses hot pond protein You couldn't make it up By Paul Hales: Wednesday 27 November 2002, 11:35 NASA SCIENTISTS say they have invented a breakthrough biological method to make ultra-small structures that could be used to produce electronics 10 to 100 times smaller than today’s components. The scientists apparently use modified proteins from 'extremophile' microbes to grow mesh-like structures so small that an electron microscope is needed to see them. These naturally-occurring microbes live in near-boiling, acidic hot springs, according to an article in on-line version of the journal Nature Materials. One of the scientists, Andrew McMillan,...

    New word in life's lexiconResearchers find 22nd amino acid in a microbe.24 May 2002JOHN WHITFIELDThere's a new word to life's vocabulary. DNA letters can be rearranged to spell out a 22nd amino acid, researchers have discovered. DNA: the letters of life have more permutations than we thought. © Getty Images The scientists who cracked life's genetic code in the 1950s said that it writes a mere 20 'words' - the amino acids from which the myriad proteins in all life are built. But in 1986 another amino acid was discovered in bacteria. "We thought the 21st was an aberration,...
