Experts propose ‘cyber war’ on cancer

By | September 4, 2012

In the face of mounting evidence that cancer cells communicate, cooperate and even engage in collective decision-making, biophysicists and cancer researchers at Rice University, Tel Aviv University and Johns Hopkins University are suggesting a new strategy for outsmarting cancer through its own social intelligence.

“We need to get beyond the notion that cancer is a random collection of cells running amok,” said Herbert Levine, co-director of Rice’s Center for Theoretical Biological Physics (CTBP) and co-author of the cover article in this week’s Trends in Microbiology that pulls together dozens of recent discoveries about the social behavior of cancer cells. “These cells lead sophisticated social lives.”

Article co-author Eshel Ben-Jacob, a senior investigator at CTBP, said, “Cancer is a sophisticated enemy. There’s growing evidence that cancer cells use advanced communications to work together to enslave normal cells, create metastases, resist drugs and decoy the body’s immune system.”

Ben-Jacob, Levine and Donald Coffey, a noted cancer researcher at Johns Hopkins, suggest in the article that cancer researchers act like modern generals and go after their enemy’s command, control and communication capabilities. The article is in volume 20, issue 9, pages 403-410 of the journal.

“It’s time to declare a cyber war on cancer,” said Ben-Jacob, who, along with Coffey, is speaking today at a workshop titled “Failures in Clinical Treatment of Cancer” at Princeton University.

Ben-Jacob said cancer cells have been shown to cooperate to elude chemotherapy drugs, much like bacteria that communicate and act as a team to resist attacks from antibiotics. He said some cancers appear to sense when chemotherapy drugs are present and sound an alarm that causes cells throughout a tumor to switch into a dormant state. Similar signals are later used to sound the “all clear” and reawaken cells inside the tumor.

“If we can break the communication code, we may be able to prevent the cells from going dormant or to reawaken them for a well-timed chemotherapeutic attack,” Ben-Jacob said. “This is just one example. Our extensive studies of the social lives of bacteria suggest a number of others, including sending signals that trigger the cancer cells to turn upon themselves and kill one another.”

The article cites numerous examples of similarities between the behavior of bacterial colonies and cancerous tumors.

“The parallels between the communal behaviors of bacteria and cancer cells suggest that bacteria can serve as a valuable model system for studying cancer,” said Coffey, professor of urology, oncology, pathology and pharmacology and molecular sciences at the Johns Hopkins University School of Medicine. “We believe this approach could be particularly valuable for investigating intractable problems like metastasis, relapse and multiple drug resistance.” …

via Experts propose ‘cyber war’ on cancer.

Cancer is a natural protective response by the body. The cyber war needs to be on the real causes of cancer such as carcinogenic chemicals which have a protected status in today’s industry-profit-ruled world, and on the junk food that damages our immune systems.

Even healthy people have thousands of cancer cells. They show up during cell reproduction due to errors in DNA replication. They are found and destroyed by a heathy immune system.

    I agree about the immune system being the real focus of attention in ‘curing’ cancer. We’re all doing it all the time but just don’t know about it unless it gets out of control.
