...d then take over the cellular machinery. When they succeed in doing this, an infection occurs. Viruses are so good at taking over cells that researchers have long dreamed of exploiting the specific attraction viruses have to certain cells and using it as a homing device to seek and enter cancer cells.

This situation occurs when increased TEL2 activity reduces the cell's ability to trigger apoptosis in response to relentless prodding by MYC to keep multiplying. As the p...
