体外研究 低浓度的果糖不会导致组织因子(TF)-mRNA水平的任何显着增加。相反,与未刺激的细胞相比,较高的果糖浓度在60分钟时引起TF mRNA水平的增加。增加果糖浓度会导致tPA-mRNA水平显着降低。 SOD显着阻止果糖诱导的NF-κB活化,这与果糖诱导的TF表达/活性的平行减少有关[1]。
体内研究 在饲喂0%果糖,门静脉(0.060±0.006mM,所有时间点的总体平均值)和全身(0.030±0.003mM)的小鼠中,进食后果糖浓度不随时间变化。相反,食用20%果糖的野生型小鼠中的门静脉浓度从喂食后时间(t)= 0至t = 1小时增加两倍以上(~0.13mM)。同样,全身血清果糖在喂食后1小时从t = 0时的0.037升至0.13mM。 20%组中的禁食(t = 0)血清果糖与门静脉和全身水平的0%小鼠中的餐后浓度相似,表明禁食期间基线果糖浓度不受饮食影响。对于相同的饮食,时间和样本位置,KHK -/-小鼠中的血清果糖浓度比野生型小鼠中的血清果糖浓度高5到100倍。与喂食0%的小鼠相比,喂食20%果糖的小鼠的门静脉和全身葡萄糖浓度的平均值(对于所有时间点)分别为~3(P = 0.004)和~2(P = 0.04)mM。在加入果糖的KHK -/-小鼠中,与喂食葡萄糖的那些相比,全身果糖浓度大约高三倍,但在葡萄糖和果糖喂养的野生型小鼠之间相似[2]。
细胞实验 将HUVEC与果糖(0.25,1和2.5mM)一起温育30分钟。然后,用PBS洗涤细胞,然后加入新鲜培养基。在基线和果糖刺激后60分钟通过细胞培养使用TRIzol试剂提取总mRNA,并通过实时逆转录(RT)和聚合酶链反应(PCR)检查组织因子(TF)mRNA水平。在阳性对照实验中,将HUVEC与LPS(50μg/ mL)孵育30分钟,然后在60分钟时提取mRNA [1]。
动物实验 将50只年轻成年(7周龄)雄性C57BL6野生型小鼠(~18g)分成10个笼子并使其适应逆光循环。在前4天,小鼠随意喂食非纯化商业饮食。在第5天,然后在整个实验过程中,饮食在2001年被移除(点亮)并在0801(灯关闭)返回。在第8至14天,将饮食转换为含有0%果糖,10%蔗糖,20%葡萄糖(称为“0%果糖”)或20%果糖,10%蔗糖或0%葡萄糖(20%果糖)的颗粒。 )。在第15天,小鼠在喂食前在0800和黑暗阶段的0900,1030,1200和1530被杀死,每个时间点和饮食n = 5 [2]。
