Proteomics News and Research

RSS

The term 'proteome' was first coined in 1994, and refers to all the proteins in a cell, tissue, or organism. Proteomics refers to the study of the proteome. Because proteins are involved in almost all biological activities, the proteome is a rich source of biological information.

New high-throughput screening technique makes probing puzzling proteins possible

Understanding the tens of thousands of proteins that compose the human proteome has emerged as a key challenge of this century, and research efforts to date have already enabled major advances in drug discovery and understanding basic biology.

Scientists find molecular mechanisms linking sugar production and longevity

Johns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans.

Carbohydrate-based medicine

Scientists from Germany today reported a major advance toward opening the doors of a carbohydrate-based medicine chest for the 21st Century.

Bacteria discovered in amniotic fluids of women who undergo preterm birth

Researchers from Case Western Reserve University and Yale University have made a significant advancement in understanding the cause behind why some pregnant women suffer from inflammations in the inner womb without any signs of an infection.

Numbing drugs can have profound and long-term negative effects

A large proteomics study on the brains of newborn mice provides more evidence that numbing drugs often used in obstetric or pediatric medicine can have profound and long-term negative effects, even after minimal exposure.

Scientists map steps to block enzyme phosphodiesterase 5's action in heart failure

Taking a cue from the way drugs like Viagra put the biological brakes on a key enzyme involved in heart failure, scientists at Johns Hopkins have mapped out a key chemical step involved in blocking the enzyme.

Five key proteins form new, early-warning blood test before heart attack strikes

A team of Johns Hopkins biochemists has identified a mixed bag of five key proteins out of thousands secreted into blood draining from the heart's blood vessels that may together or in certain quantities form the basis of a far more accurate early warning test than currently in use of impending heart attack in people with severely reduced blood flow, or ischemia.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

Proteomics provides clues to how tuberculosis thwarts the immune system

A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.

Getting to grips with the complexity of disease proteins

Drug molecules seldom act simply on one protein but on protein complexes and networks. A deeper understanding of these 'cooperative assemblies' should lead to better targeting of drugs.

NIH funds two new centers for imaging technology for neurodegenerative disorders and software for protein analysis

The National Center for Research Resources (NCRR), a part of the National Institutes of Health (NIH), announced today it will provide up to an estimated $11 million over the next five years to create two new Biomedical Technology Research Centers (BTRCs) that will provide researchers nationwide with access to specialized research tools, training and state-of-the-art equipment.

Link found between mitochondria and tumor formation in stem cells

Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors.

New technology to analyse human cells

A new technology which enables scientists to identify proteins by making a map of the energy flow inside the protein is revealed in Proceedings of the National Academy of Sciences (PNAS) journal.

Enzyme may explain how hepatitis C infection causes fatty liver

A key enzyme may explain how hepatitis C infection causes fatty liver - a buildup of excess fat in the liver, which can lead to life-threatening diseases such as cirrhosis and liver cancer, report University of Pittsburgh Graduate School of Public Health and School of Medicine researchers.

Protein found in immune cells may be a reliable marker for schizophrenia risk

Schizophrenia is a severe and complex psychiatric illness that affects about 1% of the population. Diagnosis currently relies on subjective clinical interviews and the assessment of ambiguous symptoms, which frequently leads to delayed diagnosis and treatment. As such, biomarkers that would indicate schizophrenia risk or onset would be extremely useful.

European research project to explore Alzheimer's diagnosis

VTT Technical Research Centre of Finland, GE Healthcare, a division of the General Electric Company (NYSE: GE) and a Consortium of leading research institutions across Europe announced the PredictAD project, a research collaboration aimed at developing new diagnostic procedures for patients with Alzheimer's disease.

Researchers identify biomarkers of early-stage pancreatic cancer in mice and man

A multicenter team of researchers has identified a panel of proteins linked to early development of pancreatic cancer in mice that applies also to early stages of the disease in humans - a breakthrough that brings scientists a significant step closer to developing a blood test to detect the disease early, when cure rates are highest.

Luxembourg invests in biomedical research

The Government of the Grand Duchy of Luxembourg announced on June 5, 2008 the implementation of a strategic partnership initiative with three U.S. research institutions. As part of the initiative, the Government will invest approximately 140 million euros over the next five years as it aims to develop a centre of expertise in the area of molecular medicine.
