Scientists have long wondered how maternal diabetes, malnutrition and placental dysfunction impair fetal nephrogenesis. Anew study discovered a link between prenatal metabolic stress and nephron deficit via dysregulation of DNA methylation — an epigenetic mechanism that is essential for the renewal and differentiation of nephron progenitors.
长期以来,科学家们一直想知道母体糖尿病、营养不良和胎盘功能障碍是如何损害胎儿肾发生的。一项新的研究发现,产前代谢应激与肾单位缺陷之间存在联系,其通过 DNA 甲基化的失调来实现,而 DNA 甲基化是肾祖细胞更新和分化所必需的表观遗传机制。
