Cancer cells need food to survive and grow. They're very good at getting it, too, even when nutrients are scarce. Many scientists have tried killing cancer cells by taking away their favorite food, a sugar called glucose. Unfortunately, this treatment approach not only fails to work, it backfires—glucose-starved tumors actually get more aggressive. In a study published January 31 in the journal Cell, researchers at Sanford-Burnham Medical Research Institute discovered that a protein called PKC? is responsible for this paradox. The research suggests that glucose depletion therapies might work against tumors as long as the cancer cells are producing PKC?.
