Penn Medicine News Release
PHILADELPHIA Researchers at the University of Pennsylvania School of Medicine
have identified a master switch that might prevent cancer cells from
metastasizing from a primary tumor to other organs. The switch is a
protein that, when in the on position, maintains the normal character
of cells that line the surface of organs and body cavities. These
epithelial cells are the type of cell from which most solid tumors
arise. However, when the switch is turned off or absent, epithelial
cells acquire characteristics of another cell type, called mesenchymal
cells, and gain the ability to migrate and move away from the primary
tumor. The researchers report their findings in this months issue of Molecular Cell (view journal article)... Read More
