The Critical Window, Epigenetics, and Stress — and Maybe Mental Health too

The past few weeks have been good for stress. Two labs published studies supporting the idea that stress during sensitive periods in early development can cause epigenetic changes affecting how an organism turns out. These studies look at mice and humans, respectively. I’m diving into the mouse study today — it’s got two kinds of epigenetics: an inherited, probably chromatin-mark imprinting angle; and an miRNA angle. I’ll get to the human study from the Kobor lab next time. As an aside, I find “stress and epigenetics”  especially interesting because I’m always looking for clues about how this new-ish field is perceived and represented by the lay public, and “stress” is a lay-public magnet. As I’ve talked about before, aside from … Continue reading →
