From Epigenetic Associations to Biological and Psychosocial Explanations in Mental Health.

The development of mental disorders constitutes a complex phenomenon driven by unique social, psychological and biological factors such as genetics and epigenetics, throughout an individual's life course. Both environmental and genetic factors have an impact on mental health phenotypes and act simultaneously to induce changes in brain and behavior. Here, we describe and critically evaluate the current literature on gene-environment interactions and epigenetics on mental health by highlighting recent human and animal studies.

Methodologies of Neuroepigenetic Research: Background, Challenges and Future Perspectives.

Over the last years, interest in epigenetic mechanisms has strongly increased in the field of neuroscience. Neuroepigenetics has intensely evolved and now refers to the assessment of a variety of epigenetic marks which can be found across several regions of the healthy or diseased brain. These marks include DNA (hydroxy)methylation, a large diversity of post-translational histone modifications and an increasing number of non-coding RNAs.
