摘要

ABSTRACTEicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) modulate cellular metabolic functions and gene expression. This study investigated the impacts of EPA and DHA on gene expression and morphological changes during adipogenic inducement in C2C12 myoblasts. Cells were cultured and treated with differentiation medium with and without 50?μM EPA and DHA. Cells treated with fatty acids had noticeable lipid droplets, but no formation of myotubes compared to control group cells. The expression levels of key genes relevant to adipogenesis and inflammation were significantly higher (P?

<0.05)。补充脂肪酸后,与肌发生,线粒体生物合成和功能有关的基因表达较低(

<0.05)。而且,脂肪酸处理降低了分化细胞中的氧消耗率(P <0.05)。这表明通过补充EPA和DHA阻止肌管形成,使成肌细胞进入静止状态,并使成肌细胞成脂转分化。数据还表明,妊娠期过量使用EPA和DHA可能将胎儿间充质干细胞分化带入脂肪形成的命运,并对儿童肥胖产生长期影响。
