哺乳动物早期发育期间的营养会永久性地影响成年人的健康,包括增加患2型糖尿病和冠心病的风险。然而,这种编程背后的分子机制还没有明确的定义。在这里,我们证明了miRNA表达的程序性变化将早期生命营养与长期健康联系在一起。具体地说,我们发现miR-483-3p在低出生体重成人和早期暴露于次佳营养的糖尿病前期成年大鼠的脂肪组织中上调。我们证明,在体外对miR-483-3p水平的操纵实质上调节了脂肪细胞分化和储存脂质的能力。我们发现,其中一些效应是通过翻译抑制生长/分化因子-3介导的,生长/分化因子-3是miR-483-3p的靶标。我们认为,在体内miR-483-3p表达增加,受生命早期营养的影响,限制了脂肪组织中脂肪的储存,导致脂毒性和胰岛素抵抗,从而增加了对代谢性疾病的易感性。
Nutrition during early mammalian development permanently influences health of the adult, including increasing the risk of type 2 diabetes and coronary heart disease. However, the molecular mechanisms underlying such programming are poorly defined. Here we demonstrate that programmed changes in miRNA expression link early-life nutrition to long-term health. Specifically, we show that miR-483-3p is upregulated in adipose tissue from low-birth-weight adult humans and prediabetic adult rats exposed to suboptimal nutrition in early life. We demonstrate that manipulation of miR-483-3p levels in vitro substantially modulates the capacity of adipocytes to differentiate and store lipids. We show that some of these effects are mediated by translational repression of growth/differentiation factor-3, a target of miR-483-3p. We propose that increased miR-483-3p expression in vivo, programmed by early-life nutrition, limits storage of lipids in adipose tissue, causing lipotoxicity and insulin resistance and thus increasing susceptibility to metabolic disease.
