一碳(1C)代谢对早期发育至关重要,因为它为DNA、蛋白质和脂质的生物合成以及基因组的表观遗传修饰提供了1C单位。在生命早期建立的表观遗传标记可以维持,并对以后的基因表达和功能产生持久的影响。动物和人类研究越来越多地表明,产前1C营养素缺乏会损害胎儿的生长,神经发育和儿童时期的心脏代谢参数,而母亲充足的1C营养素摄入量可以防止这些有害的结果。然而,最近的研究也强调了母体1C营养过剩或失衡破坏早期发育的潜在风险。需要进一步的研究来描述产前1C营养素暴露、表观遗传修饰和发育结果之间的剂量反应关系。
One carbon (1C) metabolism is critical for early development as it provides 1C units for both biosynthesis of DNA, proteins, and lipids and epigenetic modification of the genome. Epigenetic marks established early in life can be maintained and exert lasting impacts on gene expression and functions later in life. Animal and human studies have increasingly demonstrated that prenatal 1C nutrient deficiencies impair fetal growth, neurodevelopment and cardiometabolic parameters in childhood, while sufficient maternal 1C nutrient intake is protective against these detrimental outcomes. However, recent studies also highlight the potential risk of maternal 1C nutrient excess or imbalance in disrupting early development. Further studies are needed to delineate the dose-response relationship among prenatal 1C nutrient exposure, epigenetic modifications, and developmental outcomes.
