J Clin Invest:科学家们找到攻克脂肪肝的新目标,或能根除全球10亿人的疾病!

2017-10-05 佚名 Medicalxpress

如果你是全世界二十亿超重肥胖的人之一,如果你是全世界十亿脂肪肝患者之一,那么医生的第一个建议是减少卡路里的摄入量,特别要减少高果糖,玉米糖浆,加糖饮料和其他加工食品。

如果你是全世界二十亿超重肥胖的人之一,如果你是全世界十亿脂肪肝患者之一,那么医生的第一个建议是减少卡路里的摄入量,特别要减少高果糖,玉米糖浆,加糖饮料和其他加工食品。

乔斯林糖尿病中心的研究人员在对小鼠进行的试验中发现,在所有高脂肪饮食的小鼠中,摄入果糖的小鼠肝脏损坏最大,为了解释不同的结果,科学家们还在继续调查这一现象的生物过程。

虽然脂肪肝通常不会发展成致命的肝病,然而,这一情况还是令人担忧的,来自乔斯林的研究人员针对肥胖,2型糖尿病,脂肪肝等代谢疾病对小鼠进行了试验。参加实验的小动物们分别定期喂以高脂肪的饮食和白开水,或者是高脂肪饮食搭配加果糖或葡萄糖的水。

实验的目的是为了得出更精确的结论,那就是果糖和葡萄糖在饮食中究竟起着怎样的作用。在为期10周的试验中,所有的动物都进行了正常的饮食,在高脂肪的饮食中,果糖和葡萄糖之间存在着显着的差异。其中,果糖的代谢结果更糟糕。研究人员发现,生产酶Khk是果糖代谢的第一步,当科学家们检查并对比正常人类的肝脏样本与脂肪肝或肥胖青少年的肝脏样本时发现,肥胖或脂肪肝人群的Khk水平较高。

这一发现为科学家们对抗果糖代谢提供了新的目标,为了跟进这种可能性,科学家又进行了一系列的验证,但最引人注目的是还是高脂肪搭配高果糖饮食,通过试验结果,科学家们相信新的分子目标定能攻克脂肪肝。
