Scientists uncover role of cancer stem cell marker: controlling gene expression

Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have made an extraordinary advance in the understanding of the function of a gene previously shown to be part of an 11-gene "signature" that can predict which tumors will be aggressive and likely to spread.

Current state of the art in glycoscience

Sugars were once credited with magical healing powers but are now seen like salt as an evil necessary in small doses but the cause of numerous diseases such as diabetes if taken in excess.

Alzheimer's molecule is a smart speed bump on the nerve-cell transport highway

Researchers at the University of Pennsylvania School of Medicine discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease.

Altering brain's lipid metabolism reduces Alzheimer's plaques in mice

Increasing levels of a protein that helps the brain use cholesterol may slow the development of Alzheimer's disease changes in the brain, according to researchers studying a mouse model of the disease at Washington University School of Medicine in St. Louis.
