: fructose consumption from added sugars correlates with the epidemic rise in MetS and CVD. Maternal fructose intake has been described to program metabolic diseases in progeny. However, consumption of fructose-containing beverages is allowed during gestation. Cholesterol is also a well-known risk factor for CVD. Therefore, it is essential to study Western diets which combine fructose and cholesterol and how maternal fructose can influence the response of progeny to these diets. : a high-cholesterol (2%) diet combined with liquid fructose (10%), as a model of an unhealthy Western diet, was administered to descendants from control and fructose-fed mothers. Gene (mRNA and protein) expression and plasma, fecal and tissue parameters of cholesterol metabolism were measured. Interestingly, progeny from fructose-fed dams consumed less liquid fructose and cholesterol-rich chow than males from control mothers. Moreover, descendants of fructose-fed mothers fed a Western diet showed an increased cholesterol elimination through bile and feces than males from control mothers. Despite these mitigating circumstances to develop a proatherogenic profile, the same degree of hypercholesterolemia and severity of steatosis were observed in all descendants fed a Western diet, independently of maternal intake. An increased intestinal absorption of cholesterol, synthesis, esterification, and assembly into lipoprotein found in males from fructose-fed dams consuming a Western diet could be the cause. Moreover, an augmented GLP2 signalling seen in these animals would explain this enhanced lipid absorption. : maternal fructose intake, through a fetal programming, makes a Western diet considerably more harmful in their descendants than in the offspring from control mothers.
: 果糖(来自添加糖)的摄入与代谢综合征和心血管疾病的流行上升有关。已经描述了母体果糖摄入会导致后代代谢疾病的发生。然而,在妊娠期间允许饮用含果糖的饮料。胆固醇也是心血管疾病的一个众所周知的危险因素。因此,研究含有果糖和胆固醇的西方饮食以及母体果糖如何影响后代对这些饮食的反应是至关重要的。: 给来自对照组和果糖喂养组的后代喂食高胆固醇(2%)饮食(结合液体果糖(10%)),作为不健康的西方饮食模型。测量胆固醇代谢的基因(mRNA 和蛋白质)表达以及血浆、粪便和组织参数。有趣的是,与对照组母亲的雄性后代相比,来自果糖喂养母亲的后代摄入的液体果糖和富含胆固醇的食物较少。此外,与对照组母亲的雄性后代相比,果糖喂养母亲的后代在喂食西方饮食时通过胆汁和粪便排出的胆固醇增加。尽管存在这些减轻的情况来形成促动脉粥样硬化的特征,但所有喂食西方饮食的后代都表现出高胆固醇血症和脂肪变性的严重程度与对照组母亲的雄性后代相同,而与母体摄入无关。在喂食西方饮食的果糖喂养母鼠的雄性后代中发现的胆固醇吸收增加、合成、酯化和组装到脂蛋白中可能是导致这种情况的原因。此外,在这些动物中观察到的 GLP2 信号增强可以解释这种增强的脂质吸收。: 母体果糖摄入通过胎儿编程,使西方饮食对其后代的危害性比对照组母亲的后代大得多。
