Launching a 'social networking war' against cancer
Date:8/14/2012

Experts agree that, more than ever before, modern wars will be fought in the cyber zone, targeting an enemy's communications technology to cause untold damage. Now a Tel Aviv University researcher is suggesting that the same tactics should be employed in the battle against one of the body's deadliest enemies cancer.

In an article published in Trends in Microbiology, Prof. Eshel Ben-Jacob of TAU's School of Physics and Astronomy and Prof. Herbert Levine of Rice University, long-time bacteria researchers, and Prof. Donald Coffey of Johns Hopkins University, a renowned cancer researcher, examine the shared traits of cancer cells and bacteria. Like bacteria, cancer cells rely on communication and "social networking" to become powerful entities within the body. Inspired by the social and survival tactics of bacteria, the team presents a new picture of cancer as a meta-community of smart communicating cells possessing special traits for cooperative behavior.

Knowing the enemy

For many years, scientists ignored the complex social interactions of bacteria, now the number three killer in hospitals in the Western world. The researchers believe that medical professionals are similarly "underestimating the enemy" when it comes to cancer cells that exhibit many similar behaviors.

The parallels that can be drawn between the two types of cells are astounding. While healthy cells are highly disciplined, responding to chemical and physical cues telling them how to behave, bacteria and cancer cells override this control by using different chemical and genetic pathways. They proliferate quickly to make rapid genetic changes, avoiding the body's immune system and developing drug resistance.

Using intricate communication, cancer cells can distribute tasks, share resources, differentiate, and make decisions. Before sending cells to colonize organs and tissues throughout the body (metastasis), "spying cells" explore the
