In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
The International Human Epigenome Consortium presents a series of studies on how epigenetics influences immunity, cell lineage determination, and differentiation.
Using CRISPR and other tools, scientists are modifying DNA methylation, histone marks, and other modifiers of gene expression to understand how they affect health and disease.
