Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Thalidomide improves remission in myeloma

Myeloma is one of the least curable cancers and involves plasma cells, the white blood cells that produce antibodies.

Scientists create a mosquito resistant to Type 2 dengue fever virus

Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year.

G protein-coupled receptors cool passion of 'kiss and run' nerve cells

A new subtlety in the process of how the body's nervous system relays information may hinge on how "wet" the "kiss" is when one neuron fires a packet of neurotransmitter across a synapse to a receptive nerve cell.

Details of protein-cleaving complex key to microbe's survival may improve drug design

With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival.

New way to study proteins in live cells

For the first time, Johns Hopkins researchers were able to easily jumpstart the activity of a well-known cancer protein in live cells with a small molecule, a strategy that pinpointed key players in the cancer process and can be used to determine new therapeutic targets.

Genetic switch that turns off an oxygen-poor cell's combustion engine - finding has potential to limit toxic molecules

Johns Hopkins researchers have discovered a previously unrecognized role played by the gene HIF-1 as it helps cell survive when a lack of oxygen decreases production of an energy-rich molecule called ATP and increases production of toxic molecules.

New genome-wide map of miRNA-MRNA interactions

Researchers at New York University's Center for Comparative Functional Genomics and the University of California, Berkeley have used computational analyses to predict a genome-wide map of microRNA (miRNA) targets in the animal model organism, Caenorhabditis elegans (C. elegans).

Cornell develops technique for making living, functional cells glow

The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease.

ATF2 protein may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment

Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease.

Soy protein, almonds, plant sterol enriched margarines, oats and barley among most effective cholesterol-lowering foods

Cholesterol-lowering foods such as soy protein, almonds, plant sterol enriched margarines, oats and barley may reduce cholesterol levels more effectively when eaten in combination, says a new University of Toronto study by Professor David Jenkins.

Pre-eclampsia kidney disease link

Pre-eclampsia is a complication in pregnancy occurring in approximately eight percent of all pregnancies. It is characterised by elevated blood pressure and protein in the urine. It generally develops after 20 weeks of pregnancy.

Potential new treatment for Huntington and Parkinson patients

A potential new treatment for neurodegenerative disorders, which seems to be able to reduce the toxic protein aggregates characteristic of many of these diseases, is published online this week in the journal Proceedings of the National Academy of Sciences.

Validation of cardiovascular risk scores in a liver transplant population

Two methods of assessing a patient's risk of cardiovascular events - SCORE and PROCAM - proved more valuable for liver transplant recipients than an alternative method, according to a new study.

Study looks at how two forms of vitamin E affect the health of animal cells

One of the most powerful antioxidants is truly a double-edged sword, say researchers at Ohio State University who studied how two forms of vitamin E act once they are inside animal cells.

Chocolate milk could be key to longer life

The popular saying goes that 70 is the new 60 and 60 is the new 50, unfortunately for much of New Zealand's ageing population declining muscle function means it simply isn't true.

Johns Hopkins scientists identify protein fragment which may lead to a simple test for multiple sclerosis

Johns Hopkins scientists report the discovery of a protein found only in cerebrospinal fluid that they say might be useful in identifying a subgroup of patients with multiple sclerosis (MS) or identifying those at risk for the debilitating autoimmune disorder.

Mutant genes trigger AMD but may lighten the way to new treatments

According to new research in the U.S., the most common form of blindness in the elderly, age-related macular degeneration (AMD), can be attributed to just two genes which trigger the condition.
