Cancer-Fighting Goodness Found in Cholesterol, Study Suggests
A Simon Fraser University researcher is among four scientists who argue that cholesterol may slow or stop cancer cell growth. They describe how cholesterol-binding proteins called ORPs may control cell growth in A Detour for Yeast Oxysterol Binding Proteins, a paper published in the latest issue of the Journal of Biological Chemistry.
