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.

Molecule that destroys bone also protects it

An immune system component that is a primary cause of bone destruction and inflammation in autoimmune diseases such as rheumatoid arthritis actually protects bone in the oral cavity from infectious pathogens that play a major role in periodontal disease in humans, research at the University at Buffalo has shown.

Increasing SUMO protein in brain could be a way of treating epilepsy and schizophrenia

The brain contains about 100 million nerve cells, each having 10,000 connections to other nerves cells. These connections, called synapses, chemically transmit the information that controls all brain function via proteins called receptors. These processes are believed to be the basis of learning and memory.

Oral vaccine prevents prion disease in mice

An oral vaccine can prevent mice from developing a brain disease similar to mad cow disease, according to research presented at the American Academy of Neurology's 59th Annual Meeting in Boston.

New view of photosynthesis

During the remarkable cascade of events of photosynthesis, plants approach the pinnacle of stinginess by scavenging nearly every photon of available light energy to produce food.

Reducing levels of the protein tau can prevent seizures and neurological deficits related to Alzheimer's disease

The findings, reported in the journal Science, demonstrate that when tau is removed from mice genetically engineered to simulate Alzheimer's disease, their memory function is retained and they live a normal lifespan. Reducing tau levels also made mice more resistant to epileptic seizures.

New understanding of genetic mutation that contributes to autism

The investigators now know more about how the mutation causes problems with a specific gene and are testing for additional mutations of the same gene in other people with autism.

Nitric oxide may be the key to why specific drugs for heart failure or asthma lose their effectiveness over time

A naturally occurring molecule in the body appears to control whether certain medications, such as beta adrenergic receptor agonists used in acute heart failure or in inhalers for asthma, lose their effectiveness over time.

Research paves the way for new therapies designed to manage heart disease in older population

Ischaemic heart disease, characterised by reduced blood flow to the heart, is Australia's and the world's leading cause of death.

Nutrient "floodgate" protects against inflammatory immune response

After every meal, the body must prevent the immune system from launching an all-out fight against food.

Study on cerebral malaria in children living in an endemic region

Scientists at CNRS and the Pasteur Institute, collaborating with physicians in Gabon, have just undertaken a study on cerebral malaria in children living in an endemic region.

Scientists work out mechanism underlying asymmetric cell division in nematode worms

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells.

Simple spit test designed to detect pre-eclampsia in the early stages

The test, which is designed to be used at home, will allow mums-to-be to check for themselves whether they are at risk of the condition, which can be symptomless in the early stages but kills 1000 babies in the UK every year.

New hope for patients with premature aging condition progeria

There is renewed hope for treatment of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.

Machine preservation may promote more organ sharing

Preserving the kidneys of deceased older donors on a pump, as opposed to the conventional method of storing and transporting organs in a cooler, may lower hospital costs, improve initial organ function, and promote greater use and more sharing of organs, according to new research by Wake Forest University Baptist Medical Center.

Lab-on-a-chip speeds proteomics research

In recent years, the science of biology has been dominated by genomics, the study of genes and their functions.

Scientists discover molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years

By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1.

Gene malfunctions cause schizophrenia, depression symptoms in mice

Researchers have demonstrated for the first time that malfunction of a gene that had been associated with schizophrenia and depression does indeed cause symptoms of those disorders.

Nutritional benefits of egg consumption

Nine studies presented at the Experimental Biology 2007 meeting support the growing body of research on the nutritional benefits of egg consumption, including its promotion of weight loss and its role in providing choline, an essential nutrient often lacking in the diet that promotes brain and memory development and function.

Cause of gender differences in high blood pressure and related kidney disease

While men and women both get high blood pressure and related kidney disease, the path to get there is shorter, steeper and just different for men, researchers say.

New way to target and potentially treat tumors

Research teams at Yale University and the University of Rhode Island have demonstrated a new way to target and potentially treat tumors using a short piece of protein that acts like a nanosyringe to deliver tags or therapy to cells, according to a report in the Proceedings of the National Academy of Sciences.
