 If I had started with this idea, it's great that, you know, you can find drugs against the cancer, but let's lock the mechanisms by which the cancers are metabolizing, eating, growing. So it turns out that cancers, because they're growing so quickly and because they're dependent so cutely on nutrients, are different from normal cells. Lots of scientists have known that cancers metabolize amino acids, which make proteins. Luke Hadley and I showed that cancers metabolize sugar, especially when they're given stress with a drug differently than normal cells. So there are, in fact, Achilles heels for cancers, which will not affect normal cells, but will affect cancer cells. You may have some side effects, but they're nowhere near what you would expect from people.
