Evolutionary biology research predicts precancerous tumors

In diverse ecosystems, packed with wildly different species, evolution whizzes along. As different species accumulate mutations, some adapt particularly well to their environment and prosper.

Not all breast cancers' risk are increased by Hormone Replacement Therapy

Recent research presented at EBCC-5 from the million women study found that taking Hormone Replacement Therapy (HRT) increased the risk of some types of breast cancer, but not others.

Long term reduction in LDL cholesterol dramatically reduces risk of heart disease

A new genetic analysis of more than 12,000 individuals has found that a decrease in low density lipoprotein (LDL) cholesterol, of as little as 15 percent, sustained over the long term can dramatically reduce the risk of coronary heart disease.

Successful cell engineering may prevent bovine spongiform encephalopathy (BSE)

Researchers at Texas A&M University have successfully "knocked down" the expression of possible disease-causing genes in a cloned goat fetus, perhaps paving the way for breeding disease resistance in other animals, even those genes that might cause bovine spongiform encephalopathy (BSE), commonly known as Mad Cow Disease.

Cell therapy slows progression of metachromatic leukodystrophy

In an important discovery, scientists have demonstrated that the progression of a type of genetic brain disease is slowed and symptoms are improved in mice that received cell transplants.

The choroid plexus prevents build up of plaque related to Alzheimer's disease

Researchers have discovered that an organ in the brain called the choroid plexus apparently plays a critical role in preventing the accumulation of a protein associated with Alzheimer's disease.

Zinc's role in Alzheimer's disease

Zinc may be a familiar dietary supplement to millions of health-conscious people, but it remains a mystery metal to scientists who study zinc's role in Alzheimer's disease, stroke and other health problems.

Remaining 80% of breast cancer genes may soon be discovered

We are closer to finding the missing 80% of breast cancer genes than ever before thanks to the success of the COSMIC database (Catalogue Of Somatic Mutations In Cancer) the 5th European Breast Cancer Conference (EBCC-5) was told today.

Low-dose aspirin lowers potential for clot-forming blood cells - in both men and women

In what is believed to be the first direct comparison of blood cell testing in both sexes of 81 milligrams of acetyl salicylic acid a day, Hopkins researchers found aspirin therapy prevents the clumping together of these clot-forming cells, called platelets.

Scientists create new molecule that holds promise in fighting disease via gene therapy

Inherited diseases, as well as many cancers and cardiovascular diseases, may eventually be helped by this approach, which delivers therapeutic genes directly to cells. These genes can correct genetic defects, for example, or help the body's immune system fight cancer cells.

Crucial breakthrough in pectin biosynthesis

Most people know pectin as a common household gelling agent in making jams and jellies, but its uses are vast. It has anticancer properties, for instance, and may have a role in important biological functions including plant growth and development and defense against disease.

First evidence that dendritic cells show unprecedented sensitivity to thimerosal

A team of cell biologists, toxicologists and molecular bioscientists at UC Davis has published a study connecting thimerosal with disruptions in antigen-presenting cells known as dendritic cells obtained from mice.

Environmental chemicals implicated in cancer

New research at the University of Liverpool suggests that environmental contaminants, such as pesticides, are more influential in causing cancer than previously thought.

New discovery explains how a common gene variant may increase cancer risks

Roughly 15 percent of the population carries a gene variant that may increase the risk of developing cancer. The cause of this increased risk has been unknown until now. But now a research team at Stockholm University in Sweden can explain why.

The role of evolutionary genomics in the development of autism

Scientists at the London School of Economics, UK and Simon Fraser University, Canada have described the first hypothesis grounded in evolutionary genomics explaining the development of autism.

Gene discovered that causes dry skin and leads to eczema and asthma

Experts, lead by the University of Dundee, have discovered the gene which causes genetic skin conditions affecting millions of people.

Study identifies patients at risk for sudden cardiac death

Researchers have found a more accurate way to tell which children and teenagers are likely to be among the thousand or so who suddenly die each year in the United States from genetic heart conditions that cause arrhythmia

Genetic differences between males and females might be evened out at the rim of the nucleus

Recent research at the European Molecular Biology Laboratory (EMBL) reveals new insights into how cells achieve equality between the sexes.

Emergence of a human-adapted H5 virus is a clear threat to public health worldwide

The H5N1 avian influenza virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. So far, its spread to humans has been limited, with 177 documented severe infections, and nearly 100 deaths in Indonesia, Vietnam, Thailand, Cambodia, China, Iraq, and Turkey as of March 14, 2006, according to the World Health Organization.

Discovery of basic defect in cystic fibrosis airway glands

Scientists at Stanford University have determined that the buildup of sticky mucus found in cystic fibrosis is caused by a loss in the epithelial cell's ability to secrete fluid.
