Proteome News and Research

RSS

The proteome is the entire complement of proteins expressed by a genome, cell, tissue or organism. More specifically, it is the expressed proteins at a given time point under defined conditions. The term is a blend of proteins and genome.

Researchers develop gene therapy reversing memory loss in mice with early-stage Alzheimer's

Alzheimer's disease is the first cause of dementia and affects some 400,000 people in Spain alone. However, no effective cure has yet been found. One of the reasons for this is the lack of knowledge on the cellular mechanisms which cause alterations in nerve transmissions and the loss of memory in the initial stages of the disease.

Drugs used to treat osteoporosis appear to prevent cell membrane repair

A class of drugs widely used to treat osteoporosis appears to impede a cell's ability to repair a protective outer membrane that helps determine what enters and exits, researchers report.

Researchers uncover new aspect of autism

A team of researchers from the University of California, San Diego School of Medicine and the Center for Cancer Systems Biology at the Dana-Farber Cancer Institute has uncovered a new aspect of autism, revealing that proteins involved in autism interact with many more partners than previously known. These interactions had not been detected earlier because they involve alternatively spliced forms of autism genes found in the brain.

Researchers demonstrate advantages of HOPE fixation strategy

They discovered that the so-called HOPE method allows tissue samples to be treated such that they do not only meet the requirements of clinical histology, but can still be characterised later on by modern methods of proteomics, a technique analysing all proteins at once.

Researchers demonstrate accurate identification of amino acids

Some three billion base pairs make up the human genome-the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease.

New improved mass spectrometry for analysis of chemical and biological materials

When it comes to analyzing cell components or body fluids or developing new medications, there is no way around mass spectrometry. Mass spectrometry is a highly sensitive method of measurement that has been used for many years for the analysis of chemical and biological materials.

New sugar-test may reduce false-positive ovarian cancer screening tests

The world's most widespread test for ovarian cancer reports false-positives in 94 of 100 diagnosed cases. Now, chemists at the University of Copenhagen working with clinical researchers at University College London have developed a method able to halve the number of false-positives. When fully developed, the new test will spare a significant number of women from unnecessary worry and further testing. Furthermore, global health care providers stand to save substantial sums - just by including a test on a certain sugar molecule in tandem with the currently prevailing diagnostic test.

New probes help to quantify normally folded and misfolded conformations of protein in cells

Scientists at The Scripps Research Institute (TSRI) have invented small-molecule folding probes that enable them to quantify functional, normally folded and disease-associated misfolded conformations (shapes) of a protein-of-interest in cells under different conditions.

Long-term physical activity improves cardiovascular health by targeting heart cells' powerhouses

Whether lifting weights in a gym or just walking around the block, exercise has many benefits, such as helping people lose weight and build stronger muscles. Some studies suggest that it may reduce the risk of developing cancer and other diseases.

Scientists target protein-detection approach to systematically measure human repertoire of proteins

An international team of scientists led by Fred Hutchinson Cancer Research Center cancer proteomics expert Amanda Paulovich, M.D., has demonstrated the feasibility of large-scale, standardized protein measurements, which are necessary for validation of disease biomarkers and drug targets.

Close to 100 novel human gene regions that code for proteins may be linked to cancer

By using a new analysis method, researchers at Karolinska Institutet and Science for Life Laboratory (SciLifeLab) in Sweden have found close to one hundred novel human gene regions that code for proteins. A number of these regions are so-called pseudogenes, which may be linked to cancer.

Diabetic retinopathy incidence in upward trend

Retinal damage is one of the most common complications of diabetes, affecting about 90 percent of type 1 diabetics and 75 percent of type 2 diabetics. According to the World Health Organization (WHO), diabetic retinopathy is the leading cause of blindness in adults of working age, and its incidence is showing an upward trend.

Research on long-lived proteins may lead to better understanding of molecular basis of aging

Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are replaced with new functional copies.
