CHEO scientist advances biotherapeutics as published in Cancer Cell
Date:10/18/2011

dl in layman terms.

"To deal with this 'sticky situation', the cell turns on a few pre-programmed rescue systems that either turbocharge the folding process or slow down the production of new proteins until the cell can catch up. If this doesn't work, the cell commits suicide to stop the damage from spreading," explained Dr. Douglas Mahoney lead author of the study and member of the Stojdl lab.

Dr. Stojdl's team has identified a way to short-circuit these rescue systems so that tumor cells go straight to suicide and healthy cells stay intact. The strategy works by applying a mild stress to the cells to force them to turn on these rescue systems. But when these cells encounter an oncolytic virus, instead of trying to fix the unfolded proteins, the cell is triggered to commit suicide.

This triggering effect also works with some common chemotherapeutics that are used in cancer clinics around the world today.
