More to Cancer than DNA

December 17, 2012 | In findings published on Thursday in Science, researchers at the Princess Margaret Cancer Center in Toronto showed that cancer cells' DNA is not wholly responsible for cancer. Researchers found that despite having identical genetic mutations, colorectal cancer cells behaved as differently as if they were genetic strangers. The findings challenge the prevailing view that genes determine how individual cells in a solid tumor behave, including how they respond to chemotherapy and how actively they propagate. Reuters
