An Epigenetic Biomarker in PTSD
Abstract
There has been a growing recognition of the importance of epigenetic markers to PTSD. Epigenetic modifications are changes to the function (but not structure) of DNA that are caused by environmental exposures. To examine the extent to which an epigenetic marker cytosine methylation of the human glucocorticoid receptor as measured on the lymphocyte provides a relevant biomarker for PTSD. This will be accomplished by comparing cytosine methylation in combat veterans with and without PTSD. A second aim is to determine the association between cytosine methylation and the expression of glucocorticoid receptor related genes and splice variants of the human glucocorticoid receptor. Because we propose to measure cytosine methylation in the context of a large, multidisciplinary study (Biomarkers for PTSD: PI Dr. Charles Marmar NYUMC) we also propose to examine the relationship between this epigenetic measure and other well-studied correlates of PTSD.
