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.

Evidence of very early onset defective bone mineralization in the lumbar spine revealed in children with cystic fibrosis

In a study of children with cystic fibrosis, French researchers found evidence of very early onset defective bone mineralization in the lumbar spine that was not caused by either nutritional status or lung disease.

Rituximab reduces disease activity in multiple sclerosis

A new drug under investigation shows a reduction in disease activity in multiple sclerosis (MS), according to two studies that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston. The drug reduced disease activity as indicated by MRI scans.

Wrapping version of Gleevec fights drug-resistant cancer

A new study highlighted on the cover of this week's issue of Cancer Research finds that the anti-cancer drug Gleevec? is far more effective against a drug-resistant strain of cancer when the drug wraps the target with a molecular bandage that seals out water from a critical area.

Unstable leukemia stem cells may predispose patients to drug resistance

The BCR-ABL gene in chronic myeloid leukemia stem cells has a tendency to quickly mutate, and this may help explain why patients are predisposed to resistance to drugs like imatinib that target that gene, according to a study in the May 2 Journal of the National Cancer Institute.

Combination treatment cures mice of a very aggressive human breast tumor

A combination of three different drugs that block the HER-2 receptor, a critical cellular growth signal for some breast cancers, eradicated aggressive breast tumors in mice and could point the way toward developing better treatments inpatients, said researchers from the Breast Center at Baylor College of Medicine in a report that appears today in the Journal of the National Cancer Institute.

New interactive map shows spread of avian flu virus

Scientists here have designed a new, interactive map of the spread of the avian flu virus (H5N1) that for the first time incorporates genetic, geographic and evolutionary information that may help predict where the next outbreak of the virus is likely to occur.

Caution against over-aggressive use of erythropoiesis-stimulating agents for cancer-related anemia

Echoing recent FDA warnings, a research group from Northern Ireland cautions against over-aggressive use of a group of drugs called "erythropoiesis-stimulating agents" (ESAs) to treat anemia in some cancer patients, according to a commentary in the April issue of The Oncologist, published by AlphaMed Press.

Google maps used to track avian flu spread

An interactive "supermap" that portrays the mutations and spread of the avian flu around the globe over time should help researchers and policy makers better understand the virus and anticipate further outbreaks, according to a new study involving University of Colorado at Boulder and Ohio State University researchers.
