FKBP5 and CRHR1 polymorphisms moderate the effects of child abuse and adult stress on physical health

OBJECTIVE: Stressful life events experienced during childhood and as an adult negatively impact mental and physical health over the life span. This study examined polymorphisms from 2 hypothalamic-pituitary-adrenal axis-related genes previously associated with posttraumatic stress disorder-FKBP5 and CRHR1-as moderators of the impact of child abuse and adult stress on physical health.

DNA Methylation in Complex Disease: Applications in Nursing Research, Practice and Policy

DNA methylation is an epigenomic modification that is essential to normal human development and biological processes. DNA methylation patterns are heritable and dynamic throughout the life span. Environmental exposures can alter DNA methylation patterns, contributing to the development of complex disease. Identification and modulation of environmental factors influencing disease susceptibility through alterations in DNA methylation are amenable to nursing intervention and form the basis for individualized patient care.
