Epigenetic changes in the developing brain: Effects on behavior
This meeting was held March 28-29, 2014 at the National Academy of Sciences in Washington, D.C. and organized by Donald W. Pfaff (The Rockefeller University) and Eric Barrington Keverne (King’s College, Cambridge).
The earliest stages of brain development are susceptible to modification by epigenetic processes whose analyses have proceeded less comprehensively in neurons than in other cell types. Yet, a rapidly increasing number of studies have shown consequences of environmental perturbations very early in life, for behavioral events much later in life. Insofar as altered regulation of transcription of specific genes are involved, epigenetic mechanisms can be invoked: DNA methylation, modification of histone N-termini, and one or more of a large number of non-coding RNA’s, as well as the fascinating field of genomic imprinting.
This Sackler Colloquium brings together experts in DNA methylation, histone chemistry and the emerging field of non-coding RNAs with practicing neuroscientists. The range of disciplines represented extends to clinical work, including a vision of what this field means for the future of psychiatry.
