to produce epigenetic changes. For example, by analyzing the brain tissue from adults who had committed suicide one study found genetic changes in those who had been abused as a child.156 That is, hippocampal gene expression was decreased in victims of child abuse compared to controls with no abuse. Another recent study found changes in prostate gene expression among men with low-risk prostate cancer in response to lifestyle changes in diet, exercise, stress management and social support.157
