Hybrid molecule causes cancer cells to self-destruct

...me of the less successful experiments, designed to avoid toxic side effects, researchers used innocuous sugar molecules such as glucose to carry butyrate into the cells. The Johns Hopkins team tried a different tack. "We didn't think they chose the right partner molecule," said Kevin J. Yarema, an assistan...
