    One Patent, Three Drugs

    Many years ago, Prof. Michael Sela and colleagues found that antibodies inhibiting EGFR, a receptor that plays a role in cancer, have a synergistic anti-cancer effect when used with chemotherapy. That discovery has now led to three cancer-treating drugs: Erbitux<sup>®</sup>, Vectibix<sup>®</sup>, and, most recently, Portrazza<sup>™</sup>, just FDA approved for a form of lung cancer.

    Science Tips, July 2012

    Three updates from the Weizmann Institute: fool's gold regulates environmental oxygen; finding a molecular mechanism behind faulty stem cells and cancer; and solving the mystery of where importins – proteins critical to healing nerve damage – are produced.

  • Science Tips, August 2007

    Three research updates from the Weizmann Institute of Science: computer simulations that mimic evolution; feeding exploding stars; and revealing the actions of a key player in colorectal cancer.

  • Why Chemotherapy Fails

    Prof. Ehud Shapiro leads research that shows how leukemia can evade chemotherapy. Using his method of mapping the family trees of cells, the team found that slowly dividing cancer cells are most likely to survive the toxic therapy. This could lead to new ways of fighting cancer.

  • Science Tips, June 2012

    Three updates from the Weizmann Institute: losing money sheds light on the evolutionary conditioning behind PTSD; blocking a chemical messenger stops cancer; and a ""microprocessor"" balances efficiency and specificity in RNA.

  • Science Tips, May 2009

    Three research updates from the Weizmann Institute: vital steps in DNA repair; secrets of sea urchins' sharp teeth; and how white blood cells resemble millipedes.

  • Science Tips, February 2013

    Three updates from the Weizmann Institute: a pre-explosion signals that a star is about to go supernova; a two-antibody approach for attacking triple-negative breast cancer; and a genetic device, operating independently in bacteria, performs DNA diagnosis.

    Leukemia Cells are Addicted to a Healthy Gene

    Leukemia cells are able to stay alive, aggressively dividing, virtually forever… but how? New Weizmann research suggests that about 25 percent of the time, there is a ""balance of terror"" between the cancer-promoting gene and a second, normal version. This normal gene functions alongside the mutation, keeping the cells both cancerous and alive.
