Childhood Stress Leaves Genetic Scars
Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children's chromosomes, called telomeres. Telomeres are DNA sequences that act like the plastic tips on shoelaces, which prevent the DNA in chromosomes from unraveling. Each time a cell divides, the telomeres become shorter until a cell dies when it can't divide anymore, reports Liz Szabo for USA Today. Idan Shalev, a post-doctoral researcher in psychology and neuroscience at the Duke Institute for Genome Sciences & Policy and lead author of the study in today's Molecular Psychiatry says, "This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress." The researchers analyzed DNA samples from twins at ages 5 and 10 and compared telomere length to three kinds of violence: domestic violence between the mother a
