Genome-wide mouse study yields link to human leukemia

..., it is regarded as methylated. In the study, the research team tested 2447 fragments in each animal. They found anywhere from 45 to 209 (.8 percent to 8.5 percent) of the fragments methylated in the mice with cancer, but only one or two methylated fragments in the other mice. "Interestingly, that same rang...
