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.

Proteomics yields new drug targets for treating cardiogenic shock

When it comes to cell signaling and bioregulation, it's tough to find a more important molecule than nitric oxide (NO). Dysfunction of NO-mediated signaling is thought to be a culprit in lethal cardiovascular conditions such as angina, and septic, cardiogenic and hemorrhagic shock; it may play a role in many other illnesses as well.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Weill Cornell experts publish review of genetic medicine

In an article published in the April issue of Nature Reviews Genetics, two experts at the Weill Medical College of Cornell University sum up the achievements, challenges and promise of a burgeoning field: genetic medicine.

Omega-3 fatty acids inhibit the growth of liver cancer cells

Two new studies by a University of Pittsburgh research team suggest that omega-3 fatty acids - substances that are found in high concentrations in fish oils and certain seeds and nuts - significantly inhibit the growth of liver cancer cells.

Scientists identify a new gene that causes the spread of cancer

Professor Philip Rudland, Dr Guozheng Wang and Dr Roger Barraclough from the University’s Cancer and Polio Research Fund Laboratories have discovered an additional member of the S100 family of protein genes - S100P - that causes the spread of cancerous cells from an original tumour to other parts of the body.

New evidence questions the simple link between prion proteins and vCJD

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

Mouse Brain Gene Expression Map at St. Jude - powerful new tool for studying brain development

Scientists at St. Jude Children's Research Hospital have given investigators around the world free access to a powerful tool for studying brain development.

Researchers develop new tool to find gene control regions

Researchers at the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function.

New way of targeting proteins to exosomes - potential for melanoma, Alzheimer's disease

Researchers at the University of Pennsylvania School of Medicine have discovered how a protein called Pmel17 is sorted by pigment cells in the skin and eye to make a fiber matrix that eventually sequesters melanin, the dark pigment found in skin, hair, and eyes.

New information about the molecular pathway used by ubiquitin

Because ubiquitin plays a key role in cell survival, scientists have already begun to develop drugs to target parts of the ubiquitin pathway in treating diseases such as cancer.

Discovery of a gene that drives anthrax bacteria's toxic effects

A study in Cell reports the discovery of a gene that drives anthrax bacteria's toxic effects. The gene could offer a potential new target for countermeasures against the lethal toxin, according to the researchers.

Drug discoveries may be aided by formation of drug-target database

The latest issue of SCIENCE magazine features a brief about the work of UMBI scientists and their Binding Database (BindingDB) project.

Study provides a boost for efforts to reverse type-1 diabetes

Researchers have been able to confirm most but not all of the results of a high-profile study that brought new hope to diabetes patients. This study provides a boost for efforts to reverse type-1 diabetes in recently diagnosed patients but not for efforts to grow new islets from spleens.

Tobacco plants being used to produce human albumin

Human serum albumin (HSA) is the intravenous protein most commonly used in the world for therapeutic ends. It is employed to stabilise blood volume and to avoid risk of a heart attack, its administration in operating theatres being almost a daily occurrence.

Gene therapy treatment for brain tumours and infections

In a study published in the March 15 issue of The Journal of Immunology, researchers at Board of Governors' Gene Therapeutics Research Institute at Cedars-Sinai Medical Center have developed a way to overcome immune privilege in the brain to eradicate potentially deadly brain tumors such as glioblastoma multiforme and other types of brain infections.

Successful cell engineering may prevent bovine spongiform encephalopathy (BSE)

Researchers at Texas A&M University have successfully "knocked down" the expression of possible disease-causing genes in a cloned goat fetus, perhaps paving the way for breeding disease resistance in other animals, even those genes that might cause bovine spongiform encephalopathy (BSE), commonly known as Mad Cow Disease.

Scandanavians shed new light on muscle efficiency

A recent study from Scandinavia shows that the well-known differences between individuals in the efficiency of converting energy stored in food to work done by muscles are related to muscle fibre type composition and to the content of specific molecules in muscle.

Trial of paclitaxel with or without bevacizumab as first-line therapy for locally recurrent or metastatic breast cancer

Results from a large, randomised clinical trial for patients with breast cancer show that those who received bevacizumab (Avastin.) in combination with paclitaxel (Taxol.) survived without the disease getting worse for almost twice as long as patients who received paclitaxel alone.

The choroid plexus prevents build up of plaque related to Alzheimer's disease

Researchers have discovered that an organ in the brain called the choroid plexus apparently plays a critical role in preventing the accumulation of a protein associated with Alzheimer's disease.
