Future diabetes drugs may target new protein interaction

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce.

How and why people become addicted to alcohol

Virginia Commonwealth University researchers have identified several genetic changes in the brains of mice caused by ethanol, which may help researchers better understand how and why people become addicted to alcohol.

Liquorice - the black stuff we love to eat, may help prevent cancer

Liquorice - the black stuff we love to eat, contains a compound - glycyrrhizic acid which may stop people with a herpes virus from developing cancer.A research team at New York University found the compound - glycyrrhizic acid - possibly has the ability to stop the virus triggering a form of cancer called Kaposi sarcoma.

Genome clues to amoebic dysentery

Each year, there are an estimated 50 million cases of amoebic dysentery, causing up to 100,000 deaths, mostly in developing countries. On Thursday 24 February 2005, researchers at the Wellcome Trust Sanger Institute and their colleagues reported in Nature magazine the genome sequence of the parasite that causes the disease, Entamoeba histolytica.

Cells can regenerate without becoming "younger"

It has long been thought that cells that regenerate tissue do so by regressing to a developmentally younger state. Now two University of Washington researchers have demonstrated that cells can regenerate without becoming "younger."

Genetic link to kidney damage after heart surgery

Specific variants of genes involved in inflammation and blood vessel constriction are strongly associated with kidney damage in patients undergoing major heart surgery, researchers at Duke University Medical Center have found.

Scientists gain new insight into DiGeorge syndrome

A collaboration of European scientists has uncovered new insight into the most common chromosomal microdeletion syndrome in humans.

Discovery of a protein JBP2, an important tool for African sleeping sickness research

Sixty million people in 36 countries of sub-Saharan Africa are threatened daily by a deadly parasitic disease known as African sleeping sickness.

Protein to protein interaction map for a better insight in cancer development

With the completion of the genome sequence of a number of organisms, analysis of the gene products, the proteins, is the on-going challenge.

Promising new strategy for Swedish medical research

Research scientists at Karolinska Institutet are planning an international initiative to map out the relationships between health, genes and lifestyle. Discussion partners include world-leading researchers from the USA, Britain, Singapore and Norway.

Methylphenidate linked to chromosomal changes

In a small but startling preliminary new study, Texas researchers have found that after just three months, every one of a dozen children treated for attention deficit/hyperactivity disorder (ADHD) with the drug methylphenidate experienced a threefold increase in levels of chromosome abnormalities—occurrences associated with increased risks of cancer and other adverse health effects.

New HIV screening method, nucleic acid amplification testing (NAAT)

Adding a new HIV screening method, called nucleic acid amplification testing (NAAT), to standard HIV testing, researchers were able to uncover six percent more cases of HIV infection in urban STD and drug treatment clinics and HIV testing sites in Atlanta than with standard HIV antibody tests alone.

Caution against FDA approval of race-based pharmaceutical

New York University Sociologist Troy Duster concludes that a pharmaceutical to combat heart disease among blacks is based on faulty research and urges the Food and Drug Administration to obtain more reliable data before approving the drug.

Common epigenetic problem doubles cancer risk

In experiments with mice, a team of scientists from the United States, Sweden and Japan has discovered that having a double dose of one protein is sufficient to change the normal balance of cells within the lining of the colon, thereby doubling the risk that a cancer-causing genetic mutation will trigger a tumor there.

Scientists have regenerated a damaged optic nerve

This achievement, which occurred in laboratory mice and is described in the March 1, 2005 issue of the Journal of Cell Science, holds great promise for victims of diseases that destroy the optic nerve, and for sufferers of central nervous system injuries.

Cutting edge technology identifies genes that are involved in the development of Alzheimer's disease

Phoenix-Researchers at the Translational Genomics Research Institute (TGen) and Kronos Science Laboratories, an affiliate of Phoenix-based Kronos Optimal Health Company, have initiated a study with unprecedented power to identify genes that are involved in the development of Alzheimer's disease, the most common form of disabling memory and thinking problems in older persons.

Pollution exposure during pregnancy can cause chromosomal abnormalities in fetal tissues

A new study of newborns in New York City reveals that prenatal exposure to combustion-related urban air pollutants alters the structure of chromosomes (the carriers of genes) of babies in the womb.

Simple saliva test can predict whether children will get cavities

A simple saliva test can predict for the first time whether children will get cavities, how many cavities they will get and even which teeth are most vulnerable, USC researchers say.

Non-invasive and invasive breast cancers share the same genetic mutations

Women diagnosed with early stage, non–invasive breast cancer who carry the same mutations in two inherited breast/ovarian cancer genes as women diagnosed with invasive breast cancer, may benefit from high risk treatment, Yale researchers report in the February 23 issue of Journal of the American Medical Association.

Researchers have identified a protein called HIF-2a, which is important in retina formation

Hoping to prevent blindness in premature babies, UT Southwestern Medical Center researchers have identified a protein that responds to oxygen levels in cells and tissues and also affects the developing eye.
