Prevalence of vCJD agent in Britain remains uncertain

First results from a large tissue survey in Britain of the agent that causes variant Creutzfeldt-Jakob disease (vCJD) are unable so far to establish that the prevalence is lower than that given by previous estimates, concludes a study published on bmj.com.

Research details function of key protein in cancer spread

Research led by David Worthylake, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, may help lay the groundwork for the development of a compound to prevent the spread of cancer. The research will be published in the May 29, 2009 issue of the Journal of Biological Chemistry.

Getting more from whole-transcript microarrays

The widely-used Affymetrix Whole-Transcript Gene 1.0 ST (sense target) microarray platform, normally used to assay gene expression, can also be utilized to interrogate exon-specific splicing. Research published today in the open access journal BMC Bioinformatics shows scientists how to monitor alternative splicing activity on a genome-wide scale, without investing in new exon microarray technologies.

Trial tests potential new angina treatment

As part of a multi-center clinical trial, UC San Diego Medical Center is evaluating the safety and effectiveness of a potential new way to treat angina - by injecting a protein that stimulates the growth of new oxygen-rich blood vessels directly into the heart. Angina is a debilitating form of chest pain caused by coronary artery disease that affects more than nine million Americans.

People with Down syndrome may have more cancer-protective genes

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Bacteria of the Yersinia genus possess a unique protein thermometer

Bacteria are experts at adaptation: as soon as they have infected an organism, they adapt their metabolism to that of their host and produce substances which protect them from the body's immune defences. How they do this is still unknown in the case of many types of bacteria.

Genentech and Biogen Idec submit applications to FDA for Rituxan in chronic lymphocytic leukemia

Genentech, Inc. and Biogen Idec today announced that the companies submitted two supplemental Biologics License Applications (sBLAs) to the U.S. Food and Drug Administration (FDA) for Rituxan (rituximab) plus standard chemotherapy for people with previously untreated or treated chronic lymphocytic leukemia (CLL).

Atherotech receives patent for ApoB measurement for determining heart disease risk

Atherotech, Inc., developer of the VAP Cholesterol Test, has announced it has received a patent on its method to derive and report apolipoprotein B100 (apoB) using the Vertical Auto Profile (VAP) technology. The patent recognizes the unique ability of the VAP Cholesterol Test to accurately report apoB, the next milestone in heart disease risk assessment.

Adult stem cells from bone marrow can deliver cancer-killing proteins to tumors

Researchers in London have demonstrated the ability of adult stem cells from bone marrow (mesenchymal stem cells, or MSCs) to deliver a cancer-killing protein to tumors.

Discovery of mutant genes in acute lymphoblastic leukemia

A research team has pinpointed a new class of gene mutations, which identify cases of childhood acute lymphoblastic leukemia (ALL) that have a high risk of relapse and death. The finding suggests specific drugs that could treat this high-risk leukemia subtype in children, particularly because such drugs are already in clinical trials for similar blood diseases in adults.

Protein neuregulin 1 critical to insulating the body's wiring could also become treatment target

A new protein identified as critical to insulating the wiring that connects the brain and body could one day be a treatment target for divergent diseases, from rare ones that lower the pain threshold to cancer, Medical College of Georgia researchers say.

Genetic variations may contribute to depression in heart disease patients

Individuals with heart disease are twice as likely to suffer from depression as the general population, an association the medical community has largely been unable to explain.

Discovery of new target in fight against osteoporosis, periodontitis

Osteoporosis and periodontitis are common diseases whose sufferers must cope with weakness, injury and reduced function as they lose bone more quickly than it is formed. While the mechanism of bone destruction in these diseases is understood, scientists have had less information about how bone formation is impaired.

Vaccine candidate successful in blocking Simian version of HIV

Researchers have successfully blocked SIV, the simian version of HIV, using a new technique that could help lead to the development of an effective HIV/AIDS vaccine, the Children's Hospital of Philadelphia. The team also included scientists from Nationwide Children's Hospital in Columbus, Ohio, and the New England Primate Research Center in Boston.
