Cancer Cells Need Normal, Non-mutated Genes to Survive

Cancer cells rely on normal, healthy genes as much as they rely on mutated genes. Using a technique called RNA interference, researchers dialed down the production of thousands of normal proteins to determine which were required for cancer cells to survive. They found that cancer cells growing in a dish rely heavily on many normal proteins to maintain their deviant state. When some of these protein levels drop, cancer cells die, but normal cells often survive.
