Researchers have identified a molecular mechanism that may explain why so many cancers spread to patients' bones -- they piggyback on signaling pathways that hematopoietic stem cells use to home to the bone marrow for self-renewal.

Researchers at Mount Sinai School of Medicine have discovered a way that mutations in a gene called LRRK2 may cause the most common inherited form of Parkinson's disease. The study, published online this month in the journal Public Library of Science, shows that upon specific modification called phosphorylation, LRRK2 protein binds to a family of proteins called 14-3-3, which has a regulatory function inside cells.

By sequencing the genome of a mouse with cancer, researchers at Washington University School of Medicine in St. Louis have uncovered mutations that also drive cancer in humans.

A new study of prostate tumors has shown that a gene, FOXO3, suppresses activation of cells related to immunity and thus leads to a reduced immune response against a growing cancer. One of the main problems in treating cancer by vaccine or immunotherapy is that tumors often evade the body’s immune response — and one of their tricks is to create an environment where immunity is inhibited or suppressed.

A combination approach for arresting and reversing amyloid plaque buildup in the brain has proven effective in studies of transgenic mice with this feature of Alzheimer's disease, said researchers from Baylor College of Medicine in a recent issue of The Journal of Neuroscience.

Avian embryos could join the list of model organisms used to study a specific type of cell migration called epiboly.  The new study provides insights into the mechanisms of epiboly, a developmental process involving mass movement of cells as a sheet, which is linked with medical conditions that include wound healing and cancer.

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.
