BACKGROUND: Childhood stress leads to increased risk of many adult diseases, such
as major depression and cardiovascular disease. Studies show that adults with
experienced childhood stress have specific epigenetic changes, but to understand
the pathways that lead to disease, we also need to study the epigenetic link
prospectively in children. RESULTS: Here, we studied a homogenous group of 48
5-year-old children. By combining hair cortisol measurements (a well-documented
biomarker for chronic stress), with whole-genome DNA-methylation sequencing, we
show that high cortisol associates with a genome-wide decrease in DNA methylation
and targets short interspersed nuclear elements (SINEs; a type of
retrotransposon) and genes important for calcium transport: phenomena commonly
affected in stress-related diseases and in biological aging. More importantly, we
identify a zinc-finger transcription factor, ZNF263, whose binding sites where
highly overrepresented in regions experiencing methylation loss. This type of
zinc-finger protein has previously shown to be involved in the defense against
retrotransposons. CONCLUSIONS: Our results show that stress in preschool children
leads to changes in DNA methylation similar to those seen in biological aging. We
suggest that this may affect future disease susceptibility by alterations in the
epigenetic mechanisms that keep retrotransposons dormant. Future treatments for
stress- and age-related diseases may therefore seek to target zinc-finger
proteins that epigenetically control retrotransposon reactivation, such as
ZNF263.
