Grant to develop high speed DNA sequence reader

Sequencing of the human genome is one of the major scientific advances of our time. But with 3 billion base pairs, initial sequencing of the human genome took 11 years and cost $1 billion to complete in 2002. Today, it costs up to $50 million to sequence 3 billion base pairs.

Gene silencing may provide hope for leukemia sufferers

Ever since the approval of Gleevec in 2001, a cancer-cell-specific drug used to treat chronic myelogenous leukemia (CML), the field of cancer therapeutics has been rushing full speed into the era of so-called "targeted" medicines.

Trojan horse technique offers potential new therapeutic approach to Alzheimer's disease

A potential new therapeutic approach to Alzheimer's disease protects brain cells in culture by drastically reducing the neurotoxic amyloid protein aggregates that are critical to the development of the disease.

Scientists have uncovered a significant new link in the chain of immune system events through which estrogen prevents bone loss

Through research in mice, the scientists discovered that an immune signaling molecule called type b transforming growth factor (TGFb) is responsible for a cascade of events that leads estrogen to prevent bone loss.

New direction for spinal cord research

A piece of the puzzle of how nerves find their way across the midline of the brain and spinal cord in a developing embryo has been found by Medical College of Georgia researchers.

Detecting diseases with no more to work with than a drop of blood

The dream of monitoring a patient's physical condition through blood testing has long been realized. But how about detecting diseases in their very early stages, or evaluating how they are responding to treatment, with no more to work with than a drop of blood!

Lag-3 gene dampens immune responses by controlling regulatory T-cell function

The discovery that the Lag-3 gene acts as a brake to prevent immune system responses from running out of control solves a mystery that has puzzled researchers since the gene was discovered 14 years ago.

Molecule that helps DNA replicate may make good target for cancer therapy

In order to divide, cells must first replicate their chromosomes. Cells use an array of proteins to accomplish the job, including a large enzyme complex that synthesizes new strands of DNA.

Researchers identify a protein that could banish allergies

The suffering of millions of people with allergies could one day be eased thanks to new research from UK investigators. Findings from the University College London branch of the Ludwig Institute for Cancer Research (LICR), published in the Oct 2004 issue of Nature, detail how inactivating a key signalling molecule called p110delta reduced the effect of allergies on mice.

New antibody to prevent respiratory syncytial virus in premature babies

Virginia Commonwealth University researchers are studying the effectiveness of introducing a new antibody in premature infants to manage the most common form of lower respiratory tract infections in children worldwide.

Discovery might improve design, effectiveness of anti-cancer drugs

Working with an enzyme that degrades anti-cancer drugs in humans, University of North Carolina at Chapel Hill biochemists and colleagues have made a discovery that they believe eventually could help improve such drugs’ design and effectiveness.

Energy blocker can eradicate large liver tumors

Building on their earlier work, Johns Hopkins researchers have discovered that an apparently nontoxic cellular "energy blocker" can eradicate large liver tumors grown in rats. Six months to more than a year after treatment was stopped, the rats are still cancer free.

Malaria vaccine candidate looks extremely promising

In a proof-of-concept study published this week in The Lancet, researchers report that GlaxoSmithKline's RTS,S/AS02A malaria vaccine candidate protected a significant percentage of children against uncomplicated malaria, infection, and even severe forms of the disease for at least six months.

Highly concentrated solution of chemical messengers could block male to female HIV transmission

Researchers in the U.S have shown that it may be possible to block the transmission of the HIV virus from a man to a woman by using a highly concentrated solution of chemical messengers that attract white blood cells to the site of infection.

Single protein appears central to the formation of the long-term memories

Researchers at the National Institute of Child Health and Human Development have discovered that a single protein appears central to the formation of the long-term memories.

Researchers stimulate the body to repair tissue damaged by peripheral arterial obstructive disease

Duke University Medical Center researchers have shown that they can stimulate the body to produce its own naturally occurring growth factors to promote blood vessel growth into tissue damaged by peripheral arterial obstructive disease (PAOD).

Researchers have identified a protein in the inner ear that translates sound into the nerve impulses used by the brain

Researchers at Harvard Medical School and their colleagues report in the October 13 Nature advanced on-line edition that they have identified a protein deep in the inner ear that they believe translates sound into the nerve impulses used by the brain.
