Hopkins team discovers how DNA changes
Using human kidney cells and brain tissue from adult mice, Johns Hopkins scientists have uncovered the sequence of steps that makes normally stable DNA undergo the crucial chemical changes implicated in cancers, psychiatric disorders and neurodegenerative diseases. The process may also be involved in learning and memory, the researchers say.
A report on their study appears online April 14 in Cell.
While DNA is the stable building block of all of an individual's genetic code, or genome, the presence or absence of a methyl group at specific locations chemically alters ...
