In a rat model of gestational diabetes mellitus (GDM) programmed in the offspring of neonatal streptozotocin-induced (nSTZ) diabetic rats, lipids are accumulated in the fetal liver in a sex-dependent way. Here, we evaluated whether maternal diets enriched in olive oil in rats that will develop GDM ameliorate lipid metabolic impairments in the fetal livers. Pregnant offspring of control and nSTZ diabetic rats (F0) were fed a 6% olive oil-supplemented diet throughout the F1 gestation. We evaluated maternal metabolic parameters as well as lipid content, expression of lipid metabolizing enzymes and protein expression of PLIN2, PPARs and PPAR coactivators in the fetal livers. The offspring of nSTZ diabetic rats developed GDM regardless of the maternal treatment. Hypertriglyceridemia in GDM rats was prevented by the olive oil-enriched maternal treatment. In the livers of male fetuses of GDM rats, the maternal olive oil-supplemented diet prevented lipid overaccumulation and prevented the increase in PPARγ and PPARδ levels. In the livers of female fetuses of GDM rats, the maternal olive oil supplementation prevented the increase in PPARδ levels and the reduction in PGC1α levels, but did not prevent the reduced lipid content. Control and GDM rats showed a reduction of lipid metabolic enzymes in the fetal livers, which was associated with reduced levels of the PPAR coactivators PGC-1α and SRC-1 in males and of SRC-1 in females. These results suggest powerful effects of a maternal olive oil-supplemented diet in the fetal liver, possibly providing benefits in the fetuses and offspring from GDM rats.

在妊娠糖尿病大鼠模型中,富含橄榄油的孕妇饮食可调节脂质代谢以及胎儿肝脏中PPAR及其共激活因子的水平。

在新生的链脲佐菌素诱导的(nSTZ)糖尿病大鼠的后代中编程的妊娠糖尿病(GDM)大鼠模型中,脂质以性别相关的方式积聚在胎儿肝脏中。在这里,我们评估了母体饮食是否会在大鼠中富含橄榄油,这些饮食会导致GDM改善胎儿肝脏的脂质代谢损害。在整个F1妊娠期中,对照组和nSTZ糖尿病大鼠(F0)的怀孕后代都饲喂6%的橄榄油补充饮食。我们评估了胎儿肝脏中的母亲代谢参数以及脂质含量,脂质代谢酶的表达以及PLIN2,PPAR和PPAR共激活因子的蛋白表达。不论母体治疗如何,nSTZ糖尿病大鼠的后代都会发展为GDM。富含橄榄油的母体治疗可预防GDM大鼠高甘油三酸酯血症。在GDM大鼠的雄性胎儿的肝脏中,补充了母体橄榄油的饮食可防止脂质过度积聚,并防止PPARγ和PPARδ水平升高。在GDM大鼠的雌性胎儿的肝脏中,补充孕妇橄榄油可防止PPARδ水平升高和PGC1α水平降低,但不能阻止脂质含量降低。对照和GDM大鼠显示胎儿肝脏中的脂质代谢酶减少,这与男性中PPAR辅激活物PGC-1α和SRC-1的水平降低以及女性中SRC-1的水平降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。补充了孕妇橄榄油的饮食可防止脂质过度积聚,并防止PPARγ和PPARδ水平升高。在GDM大鼠的雌性胎儿的肝脏中,补充孕妇橄榄油可防止PPARδ水平升高和PGC1α水平降低,但不能阻止脂质含量降低。对照和GDM大鼠显示胎儿肝脏中的脂质代谢酶减少,这与男性中PPAR辅激活物PGC-1α和SRC-1的水平降低以及女性中SRC-1的水平降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。补充了孕妇橄榄油的饮食可防止脂质过度积聚,并防止PPARγ和PPARδ水平升高。在GDM大鼠的雌性胎儿的肝脏中,补充孕妇橄榄油可防止PPARδ水平升高和PGC1α水平降低,但不能阻止脂质含量降低。对照和GDM大鼠显示胎儿肝脏中的脂质代谢酶减少,这与男性中PPAR辅激活物PGC-1α和SRC-1的水平降低以及女性中SRC-1的水平降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。补充孕妇橄榄油可防止PPARδ水平升高和PGC1α水平下降,但不能阻止脂质含量下降。对照和GDM大鼠显示胎儿肝脏中的脂质代谢酶减少,这与男性中PPAR辅激活物PGC-1α和SRC-1的水平降低以及女性中SRC-1的水平降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。补充孕妇橄榄油可防止PPARδ水平升高和PGC1α水平下降,但不能阻止脂质含量下降。对照和GDM大鼠显示胎儿肝脏中的脂质代谢酶减少,这与男性中PPAR辅激活物PGC-1α和SRC-1的水平降低以及女性中SRC-1的水平降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。这与男性PPAR激活因子PGC-1α和SRC-1的水平降低以及女性SRC-1降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。这与男性PPAR激活因子PGC-1α和SRC-1的水平降低以及女性SRC-1降低有关。这些结果表明,补充母体橄榄油的饮食对胎儿肝脏的强大作用,可能为GDM大鼠的胎儿和后代提供益处。
