The latest clues suggesting potential new ways to treat melanoma come from an unlikely source: fish. Zebrafish don't get sunburns, but they can get skin cancer – at least those fish that have been engineered to model the often deadly human cancer.

A unique antibody from a llama could prove to be a key weapon against C. difficile, a nasty infection that is a growing problem in many hospitals throughout North America.  Clostridium difficile is a common cause of infectious diarrhea in nursing homes and hospitals and usually occurs in patients who have been taking regular antibiotics for an infection.

A new NIH grant will allow biologist Robert Reenan the opportunity to study the genetics of epilepsy using an unusual method. His goal is to discover mutations that suppress seizures.

By mutating a single gene, researchers at MIT and Duke have produced mice with two of the most common traits of autism — compulsive, repetitive behavior and avoidance of social interaction. They further showed that this gene, which is also implicated in many cases of human autism, appears to produce autistic behavior by interfering with communication between brain cells.

A new way of delivering drugs to the brain has been developed by scientists at the University of Oxford.  They used the body's own transporters - exosomes - to deliver drugs in an experiment on mice.

It's been more than 20 years since scientists first discovered the gene that causes cystic fibrosis (CF), yet questions about how the mutated gene causes disease remain unanswered.  Using a newly created pig model that genetically replicates the most common form of cystic fibrosis, University of Iowa researchers have now shown that the CF protein is "misprocessed" in the pigs and does not end up in the correct cellular location.

A new protein engineered to inhibit molecules that cause inflammation not only reduces symptoms of rheumatoid arthritis in mice but also may have potential to reverse the disease's course. Researchers hope the findings will point toward a new therapy for this crippling and difficult-to-treat disease, which occurs when the immune system attacks the body's own joints.

The small study in The Lancet Neurology used a virus to add genes to brain cells, which resulted in reduced symptoms for half of patients.

Dana-Farber Cancer Institute scientists report that they have shrunk or slowed the growth of notoriously resistant pancreatic tumors in mice, using a drug routinely prescribed for malaria and rheumatoid arthritis.

Scientists at Cambridge University believe the technique, which uses stem cells, could even cure blindness one day. They have already had success in rats and hope to start trials in humans within five years.

A new study suggests that combining two experimental anticancer peptide agents might simultaneously block formation of new tumor blood vessels while also inhibiting the growth of tumor cells.

In a research study appearing in the journal Cancer Cell on March 14, scientists from Cold Spring Harbor Laboratory (CSHL) and four other institutions have identified a strategy for targeted molecular therapy in liver cancer, which currently has limited treatment options and one of the worst one-year survival rates of any cancer type.

Pilocytic astrocytoma (PA) is the most common pediatric brain tumor, and there are few medical therapies available to those patients for whom surgery is not curative. However, it has been difficult to design targeted PA therapies because the cellular mechanisms that lead to the cancer are incompletely understood, and there is no animal model of the disease.

SAN ANTONIO (March 11, 2011) — Cell biologists pondering the death of neurons — brain cells — said today that by eliminating one ingredient from the cellular machinery, they prolonged the life of neurons stressed by a pesticide chemical. The finding identifies a potential therapeutic target to slow changes that lead to neurodegenerative disorders such as Parkinson's and Alzheimer's diseases.

Several years from now, researchers at the University of Missouri say, fewer people may have to endure the discomfort and indignity of a colonoscopy.

One of the high-profile areas of research for stem cells is in treatment of spinal cord injuries -- and there was progress to report this week. Researchers were able to transplant a type of human cell into rats with spinal cord injuries to help the animals regain some motor function.

LONDON (Reuters) - Lowering cholesterol levels could help the body's immune system fight infections, British scientists said on Tuesday. A study in mice by researchers at the University of Edinburgh found a direct link between the workings of the immune system and cholesterol levels.

In a major breakthrough in the battle against Parkinson’s disease, researchers at the University of Colorado School of Medicine have discovered a drug that stops the progression of the degenerative illness in mice and is now being tested on humans.

Professor Klaus Funke from Rhur-University Bochum has shown that various stimulus patterns created using transcranial magnetic stimulation (TMS) can change the activity of distinct neuronal types.  TMS stimulates the cortex using a magnetic field – in general, brain activity drops as a result of low frequency stimulation, and increases with higher frequencies.

Research by the University of Liverpool has found that systemic inflammation caused by sepsis can be suppressed by a protein which occurs naturally in a type of roundworm.
