Canadian Postdoc in Peña Lab, Princeton Neuroscience Institute. Epigenetic signatures of early-life stress.
But wait there’s more! Our sister paper “Altered postnatal chromatin development in the NAc primes lifelong stress sensitivity” led by Rebekah Rashford and Lisa Tang (Creed Lab) is ALSO out in #JNeurosci! doi.org/10.1523/JNEUROSCI.2217-25.2026
Altered postnatal chromatin development in the nucleus accumbens primes enduring stress sensitivity
Early-life stress (ELS) sensitizes individuals to subsequent stressors to increase lifetime risk for psychiatric disorders. Within the nucleus accumbens (NAc) — a key limbic and reward-associated brai...

Read a summary here @princetonneuro.bsky.social: pni.princeton.edu/news/2026/ea... Including why we think epigenetic priming by ELS isn’t all bad
Early-life stress leaves a lasting mark on the brain
A new study from researchers at Princeton University and Washington University School of Medicine in St. Louis has uncovered a biological mechanism that may explain why early-life adversity can leave ...

Last but not least, thank you to Jay @hyejaykim.bsky.social for getting it all across the finish line with a beautiful set of knockdown experiments. Showing that Setd7-KD in ELS mice prevents exaggerated dopamine ephys and behavioral response to stress brings it all together (reviewers were right!)
So proud to have “Early-life stress alters H3K4me1 in VTA to prime stress sensitivity” out now in Neuron! This work spanned Many years and Many people contributed. Huge thanks to @hyejaykim.bsky.social, @ja-balouek.bsky.social, Luke Geiger, and Meaghan Creed www.cell.com/neuron/fullt...
Early-life stress alters H3K4me1 in VTA to prime stress sensitivity
Kim, Geiger et al. report that early-life stress increases the chromatin modification H3K4me1 and its enzymatic writer, SETD7, in the ventral tegmental area. They show that this form of epigenetic pri...
