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.

Long non-protein-coding RNA (lncRNA) sequences are often transcribed from the opposite, or antisense, strand of a protein coding gene. In the past few years, research has shown that these lncRNAs play a number of regulatory roles in the cell. For exa
