...g others. Eventually, the news reaches the genetic material inside the cell nucleus, where changes resulting in uncontrolled growth--cancer--or some other cell behavior are made. It was thought that some form of an enzyme called MEK, which belongs to the family of signaling enzymes, was the culprit.
