Novel approach to creating a vaccine to treat melanoma

A novel approach to creating a vaccine to treat melanoma has demonstrated promising effectiveness in a new laboratory study led by researchers at The Wistar Institute. About a third of melanoma patients might benefit from such a vaccine.

Moderate alcohol intake stimulates tumor angiogenesis and expression of vascular endothelial growth factor in a mouse model

University of Mississippi researchers say they have created the first-ever mammalian model of how alcohol consumption spurs tumor growth, showing that even moderate drinking resulted in larger and more robust tumors.

Breakthrough in search for new anti-malarial drugs

Scientists at Drexel University College of Medicine in Philadelphia have made a significant discovery in the fight against malaria. Drexel researchers, along with a research group at the University of Washington, have determined a critical molecular structure of the cellular motor that allows the malaria parasite to invade human cells.

Promising new targets for Alzheimer's drug therapies

An enzyme previously associated with preventing the dementia of Alzheimer's disease now appears to play an even bigger role in safeguarding against the disease, bringing the promise of new targets for drug therapies.

Enzymes that harm brain immediately after stroke may be beneficial days later

Insights from the study could change the way stroke is treated, extending the window for effective treatment from a couple of hours to a couple of weeks. The results may suggest new ideas for drug development.

Transportation of prion protein across the intestinal mucosa of scrapie-susceptible and scrapie-resistant sheep

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.

New biomarkers could help detect ovarian cancer much earlier

The search for a specific protein that could help diagnose ovarian cancer in its early stages has for years eluded researchers who are seeking a reliable and accurate test for the disease.

Enzyme released by cardiac mast cells during heart attack contributes to arrhythmia

In times of cardiac crisis, mast cells in the heart secrete a powerful enzyme, renin, that indirectly triggers dangerous arrhythmias, according to a team of researchers at the Weill Medical College of Cornell University in New York City.

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.
