Heal thyself: Systems biology model reveals how cells avoid becoming cancerous Researchers at the University of California, San Diego and three other institutions have described for the first time a web of inter-related responses that cells use to avoid becoming diseased or cancerous after being exposed to a powerful chemical mutagen. The group led by UCSD bioengineering professor Trey Ideker describe in the May 19 issue of Science an elaborate system of gene control that is triggered by chemical damage to DNA.
