Structure of protective protein in the eye lens revealed
The human eye lens consists of a highly concentrated mix of several proteins. Protective proteins prevent these proteins from aggregating and clumping. view more (2009-08-03)
Brush your teeth to reduce the risk of heart disease
Heart disease is the leading cause of death worldwide. However, many people with cardiovascular disease have none of the common risk factors such as smoking, obesity and high cholesterol. view more (2008-09-09)
CSH Protocols publishes cutting-edge methods for analyzing complex molecular interactions
With the genomes of hundreds of organisms now catalogued, one of the next major challenges is to identify proteins and their interactions. view more (2006-10-05)
Proteasome activator enhances survival of Huntington's disease neuronal model cells
To function, each living cell needs both to build new and to degrade old or damaged proteins. To accomplish that, a number of intracellular systems work in concert to keep the cell healthy and from clogging up with damaged proteins. view more (2007-02-28)
Unexpected similarities between raindrops and proteins
Raindrops and proteins seem to have a lot in common. This has been shown in a new study by scientists at Ume'å University in Sweden. The principle behind the formation of raindrops is very similar to how proteins fold. This knowledge is vital to our understanding of neurodegenerative diseases like ALS. These findings have been published in... view more... (2004-05-26)
Making bacteria make useful proteins
By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. view more (2009-09-08)
Powerful new 'molecular GPS' helps probe aging and disease processes
Scientists in Michigan are reporting the development of a powerful new probe for identifying proteins affected by a key chemical process important in aging and disease. view more (2009-09-02)
Nanoresearchers challenge dogma in protein transportation in cells
New data on signalling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer. view more (2009-09-22)
Study finds possible connection between marijuana abuse and stroke or heart attacks
Long-term harmful effects of marijuana (MJ) include risk for heart attacks and strokes in addition to impaired learning and memory. The active chemical in MJ called delta-9-tetrahyrdocannabinol (THC) is believed to exert these effects by binding to cannabinoid (CB) receptors located on several cell types in various organs. view more (2008-05-13)
Physics provides new insights on cataract formation
Using the tools and techniques of soft condensed matter physics, a research team in Switzerland has demonstrated that a finely tuned balance of attractions between proteins keeps the lens of the eye transparent, and that even a small change in this balance can cause proteins to aggregate and de-mix. view more (2007-11-12)
Fluorescence microscopy reveals why some antifreeze proteins inhibit ice growth better than others
Antifreeze or "ice structuring" proteins - found in some fish, insects, plants, fungi and bacteria - attach to the surface of ice crystals to inhibit their growth and keep the host organism from freezing to death. view more (2007-03-07)
MicroRNAs play a big part in gene regulation-and evolution
egulating when and where certain proteins are made is crucial to the normal functioning of living things. To make proteins, information from DNA is transcribed into RNA molecules and then translated into the amino acids building blocks of proteins. view more (2005-06-24)
MIT sheds light on how tumor cells form
MIT cancer researchers have discovered a process that may explain how some tumor cells form, a discovery that could one day lead to new therapies that prevent defective cells from growing and spreading. view more (2006-06-22)
HFI-1 gene has key role in both oxygen sensing, heat shock pathway
University of Oregon researchers have found an unexpected regulatory link between cellular responses to hypoxia and heat shock. Central to the discovery is a gene known as Hypoxia-Inducible Factor-1 (HIF-1) that is critical for both normal and pathological changes, making it a potential target for both health promotion and cancer therapies. view more (2006-10-26)
MNI researchers find a new role for mitochondria in cellular copper regulation
Copper is an essential part of our lives. From copper pipes and wires - to important copper-containing proteins in the body, copper is necessary for healthy growth and neurological development. view more (2007-05-02)
Mapping dynamic Polycomb group proteins during Drosophila development
The developmental passage from a ball of cells to a fruit-fly is a very complicated process involving both temporal and spatial regulation of genes and pathways. view more (2006-04-20)
3 proteins may play important role in nerve-cell repair
Some mature brain cells can grow new extensions when the amount of three particular proteins on their surface increases, a new study shows. view more (2007-04-12)
New study shows how genes control blood proteins important to health
A new study shows how genes control levels of many blood proteins implicated in disease. The findings are the result of an international collaboration between scientists at the University of Exeter, the National Institute on Aging, and the Tuscany and Florence Health Agencies. view more (2008-05-09)
Biologists discover bacterial defense mechanism against aggressive oxygen
Bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell. view more (2009-11-23)
Sugarcoating fruit fly development
Proteins are the executive agents that carry out all processes in a cell. Their activity is controlled and modified with the help of small chemical tags that can be dynamically added to and removed from the protein. view more (2009-06-01)
