PHILADELPHIA -- Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself. The research, published this month in Genes and Development, "challenges standard assumptions on the timing of when mobile DNA, so-called jumping genes, insert into the human genome," says senior author Haig H.
PHILADELPHIA -- In a study comparing two strains of mice, one susceptible to developing cancer and the other not, researchers found that a high-fat diet predisposed the cancer-susceptible strain to liver cancer, and that by switching to a low-fat diet early in the experiment, the same high-risk mice avoided the malignancy.
