<front><div type="abstract" xml:lang="en"><p><bold>Background:</bold>
Early-life exposures to tobacco smoke and some dietary factors have been identified to induce epigenetic changes in genes involved in allergy and asthma development. Omega-3 (n−3) polyunsaturated fatty acid (PUFA) intake during pregnancy could modulate key cytokines and T helper (Th) cell maturation; however, little is known about the mechanism by which ω-3 PUFA could have a beneficial effect in preventing inflammatory disorders.</p>
<p><bold>Objective:</bold>
We sought to test whether prenatal dietary supplementation with ω-3 PUFA during pregnancy may modulate epigenetic states in the infant immune system.</p>
<p><bold>Design:</bold>
This study was based on a randomized intervention trial conducted in Mexican pregnant women supplemented daily with 400 mg docosahexaenoic acid (DHA) or a placebo from 18 to 22 wk of gestation to parturition. We applied quantitative profiling of DNA methylation states in Th1, Th2, Th17, and regulatory T–relevant genes as well as <italic>LINE1</italic>
repetitive elements of cord blood mononuclear cells (<italic>n</italic>
= 261).</p>
<p><bold>Results:</bold>
No significant difference in promoter methylation levels was shown between ω-3 PUFA–supplemented and control groups for the genes analyzed; however, ω-3 PUFA supplementation was associated with changes in methylation levels in <italic>LINE1</italic>
repetitive elements (<italic>P</italic>
= 0.03) in infants of mothers who smoked during pregnancy. Furthermore, an association between the promoter methylation levels of <italic>IFNγ</italic>
and <italic>IL13</italic>
was modulated by ω-3 PUFA supplementation (<italic>P</italic>
= 0.06).</p>
<p><bold>Conclusions:</bold>
Our results indicate that maternal supplementation with ω-3 PUFA during pregnancy may modulate global methylation levels and the Th1/Th2 balance in infants. Therefore, the epigenetic mechanisms could provide attractive targets for prenatal modulation and prevention of inflammatory disorders and potentially other related diseases in childhood and adulthood.</p>
