Lessons learned from yeast about human leukemia: The power of basic model organisms in human health

The trifecta of biological proof is to take a discovery made in a simple model organism like baker's yeast and track down its analogs or homologs in "higher" creatures right up the complexity scale to people, in this case, from yeast to fruit flies to humans.
