Human Cells Secrete Cancer-Killing Protein, UK Study Finds
Date: 27.7.2009
**Human cells** are able to secrete a **cancer-killing** protein, scientists at the University of Kentucky's Markey Cancer Center have found.
Researchers led by Vivek Rangnekar, UK professor of radiation medicine, have determined that the tumor-suppressor protein **Par-4**, initially thought to be active only within cells expressing the Par-4 gene, is in fact secreted by most human and rodent cells and can target large numbers of **cancer** cells by binding to receptors on the cell surface.
