Scientists begin to untangle root cause of Alzheimer's disease
"N60" might not be the first thing that comes to mind when people think of Alzheimer's disease, but thanks to researchers from the United States, South Korea and France, this might change. view more (2009-09-04)
New crops needed for new climate
Global food security in a changing climate depends on the nutritional value and yield of staple food crops. Researchers at Monash University in Victoria, Australia have found an increase in toxic compounds, a decrease in protein content and a decreased yield in plants grown under high CO2 and drought conditions. view more (2009-06-29)
Marking anorexia with a brain protein
Eating disorders are frequently seen as psychological or societal diseases, but do they have an underlying biological cause? A new study shows that the levels of a brain protein differ between healthy and anorexic women. view more (2009-06-24)
Fragments of dinosaur protein survive in bone fossils
Proteins are tougher than we think - which is good news for scientists trying to piece together the history of evolution from fragments of ancient DNA. In this month’s (December 2000) edition of the journal, Geology, Dr Matthew Collins, of Newcastle University, England, shows how significant pieces of delicate protein have survived in... view more...

Mutant proteins result in infectious prion disease in mice
A worldwide group of scientists has created an infectious prion disease in a mouse model, in a step that may help unravel the mystery of this progressive disease that affects the nervous system in humans and animals. view more (2008-12-08)
Unraveling how cells respond to low oxygen
Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. view more (2009-08-06)
Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. view more (2008-09-24)
Huntington's disease problem start early
The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron. view more (2008-01-10)
New study raises questions about the number of people in the UK who could be incubating vCJD
A team of UK scientists found that 3 out of 12,674 stored appendix and tonsil samples showed evidence of the prion protein associated with vCJD, but urge caution about the way these results are interpreted. The research is published this week in The Journal of Pathology. The study aimed to help health policymakers estimate the numbers of people... view more... (2004-05-18)
Measuring intellectual disability
Researchers from the University of California, Davis have developed a specific and quantitative means of measuring levels of the fragile X mental retardation 1 (FMR1) protein (FMRP), which is mutated in fragile X syndrome. view more (2009-06-24)
Leeds research points to new therapy for hepatitis C treatment
Combination therapies similar to those used for HIV patients may be the best way of treating hepatitis C virus (HCV), say researchers from the University of Leeds. view more (2008-12-09)
New discovery may improve treatment of neurodegenerative diseases and type 2 diabetes
The discovery opens the way for new drugs to be designed to treat Parkinson's, type 2 diabetis, Alzheimer's and Creuzfeldt-Jacob disease. view more (2005-12-15)
New technique boosts by four times the size of a protein that researchers can analyze
Imagine you had to break a secret code, but you could see only part of the message. That's the kind of frustration researchers face when trying to identify proteins and characterize how those proteins are modified in cells by biological processes. view more (2006-10-09)
Researchers identify new function for protein missing in Duchenne muscular dystrophy
Researchers at the University of Minnesota and National Institutes of Health have identified a new function for the protein missing in people with the most common and ultimately lethal form of childhood muscular dystrophy. view more (2009-08-04)
Soy protein reduces effects of diabetes on liver
A group of researchers from Mexico has discovered that a diet rich in soy protein may alleviate fatty liver, a disease which often accompanies diabetes. view more (2005-09-07)
Cold Spring Harbor Protocols highlights reliable methods for gene and protein analyses
In their native form, the thousands of assorted proteins in our body are virtually indistinguishable. Scientists who want to examine the properties and functions of specific proteins, as well as the activities of individual genes, must rely on chemical tags to manipulate and visualize them. view more (2007-04-05)
What's the difference between a human and a fruit fly?
Fruit flies are dramatically different from humans not in their number of genes, but in the number of protein interactions in their bodies, according to scientists who have developed a new way of estimating the total number of interactions between proteins in any organism. view more (2008-05-13)
Scientists find the pathological prion protein in skeletal muscles of hamster with scrapie
In the May 2003 issue of EMBO reports, researchers from the German Robert Koch Institute in Berlin report finding the pathological prion protein PrPSc in a wide range of skeletal muscles after feeding hamsters with prion-infected food. PrPSc is believed to be an essential - if not the sole - constituent of the agent that causes BSE in cattle,... view more... (2003-04-10)
Enzyme fights mutated protein in inherited Parkinson's disease
An enzyme that naturally occurs in the brain helps destroy the mutated protein that is the most common cause of inherited Parkinson's disease, researchers at UT Southwestern Medical Center have found. view more (2009-06-26)
Stopping the clock: Genetics of tumor latency in skin cancer
Dr. Anthony E. Oro and colleagues (Stanford University) have identified two key Gli protein degradation signals that directly affect tumor latency in a mouse model of human skin cancer. view more (2006-01-20)
