ScienceDaily (May 15, 2008) — University of Saskatchewan microbiologist Wei Xiao has found a way to trigger a protein combination called 9-1-1 that sends an SOS signal for cells to fight cancer-causing agents such as industrial toxins, ultraviolet radiation, and X-rays.
The finding -- published in the journal Cell -- is seen as a breakthrough in cancer research that could lead to better cancer diagnosis through targeting defective genes. It may also pave the way for a drug that activates the SOS response in cells.
"With no exaggeration, this is a result that many in the field have awaited with anticipation for some 20 years," said Michael Ellison, director of the Institute for Biomolecular Design and Project CyberCell at the University of Alberta.
