"An examination of the gatekeeper role played by the epigenome, which can shape everything from whether people develop diseases to whether they are fat or slim by turning on and off specific genes. Scientists have long puzzled over the different fates of identical twins: both have the same genes, yet only one may develop a serious disease like cancer or autism. What's going on? Does something else besides genes determine who we are? The "something else" turns out to be a network of chemical switches that sit on our DNA, turning genes off and on. Called collectively the epigenome, the switches appear to play a major role in everything from how our cells keep their identity to whether we contract dread diseases. Epigenetic switches may even help mold our personalities—or so it appears to Canadian researchers studying a group of epigenetically modified rats. "We're in the midst of probably the biggest revolution in biology, which is going to forever transform the way we understand genetics, environment, the way the two interact, and what causes disease," says Mark Mehler, Professor of Neurology at Albert Einstein College of Medicine. "It's another level of biology, which for the first time really is up to the task of explaining the biological complexity of life." NOVA reveals the clues that have led scientists to this new picture of genetic control and expression. Researchers now suspect that it's how genes are regulated that distinguishes species. What turns them on and off? Among other things, epigenetic switches. The program closes at the controversial cutting edge of this burgeoning new field. At the M. D. Anderson Cancer Center in Houston, Texas, researchers are investigating epigenetic means to treat a deadly form of leukemia. In Washington State, a researcher finds that a toxin given to rats still affects their offspring four generations later, without producing any changes in their genes. And in Sweden, a study of historical records seems to show that the lifespan of grandchildren is affected by their grandparents' access to food. Might these effects be epigenetic? Might our experiences, by changing our epigenomes, literally change the fate of our offspring ... and their offspring ... and theirs in turn? Some researchers are already convinced. "
