Nat Commun:肝脏miR-378调控胰岛素信号控制糖脂代谢

2014-12-11 MedSci MedSci原创

microRNA 是一类非编码小RNA分子,在基因转录后水平通过对靶mRNA 的翻译抑制或降解,继而调控基因的表达。肝脏是机体十分重要的代谢器官,对于机体糖脂代谢的平衡以及能量稳态的维持非常重要,肝脏代谢的紊乱常会导致多种代谢性疾病的发生,比如脂肪肝、肥胖、II型糖尿病等。越来越多的研究发现肝脏功能的紊乱往往伴随着microRNA的异常表达,因此深入了解和研究microRNA在肝脏能量代谢中的

microRNA 是一类非编码小RNA分子,在基因转录后水平通过对靶mRNA 的翻译抑制或降解,继而调控基因的表达。肝脏是机体十分重要的代谢器官,对于机体糖脂代谢的平衡以及能量稳态的维持非常重要,肝脏代谢的紊乱常会导致多种代谢性疾病的发生,比如脂肪肝、肥胖、II型糖尿病等。越来越多的研究发现肝脏功能的紊乱往往伴随着microRNA的异常表达,因此深入了解和研究microRNA在肝脏能量代谢中的作用和机制,对于寻找治疗代谢性疾病的有效靶点以及预防方法均具有重要意义。 

胰岛素信号通路对肝脏葡萄糖和脂质代谢的调控至关重要,胰岛素信号通路是指从胰岛素结合到细胞膜上的胰岛素受体,继而激活下游蛋白的磷酸化级联反应,最终产生各种生理效应的一系列过程。在肝脏糖脂代谢方面,胰岛素信号通路的激活一方面刺激肝脏糖酵解和脂肪酸合成,另一方面抑制糖异生和脂肪酸氧化。其中任一环节受损或失调时,就可能扰乱机体的代谢稳态平衡。 

12月4日,Nature Communications (《自然-通讯》)在线发表了中国科学院上海生命科学研究院营养科学研究所应浩研究组的最新研究成果:Hepatic miR-378 targets p110αand controls glucose and lipid homeostasis by modulating hepatic insulin signaling。该研究发现肝脏miR-378作为胰岛素信号通路的一个重要制动因子,通过影响肝脏胰岛素信号通路基础活性,调控葡萄糖以及脂质代谢的动态平衡。 

应浩研究员指导的博士生刘威和曹鸿超等发现,肝脏中miR-378/378*的表达水平会随着进食状态的不同而改变。当在小鼠肝脏中过表达miR-378/378*时,小鼠呈现出明显的肝脏胰岛素抵抗症状,表现为小鼠高血糖以及肝脏和血清甘油三酯的减少。这一现象与胰岛素信号通路中一些关键蛋白敲除小鼠模型相似。机制研究发现,miR-378/378*对胰岛素信号通路的作用是由miR-378介导的,而且miR-378对肝脏糖脂代谢的调控作用是由p110α介导的。进一步的研究发现,缺失miR-378/378*的小鼠,胰岛素敏感性增强,表现为低血糖以及肝脏高甘油三酯症状。这些研究结果表明:在不同营养状况下,机体可通过调整肝脏miR-378的水平重设肝脏胰岛素信号通路的基础活性,从而有助于糖脂代谢发生适应性改变以满足机体所需。此外,研究还发现,在ob/ob小鼠肝脏中过表达miR-378,可以显著减少肝脏甘油三酯含量,改善ob/ob小鼠的脂肪肝症状。总之,这些发现提高了人们对肝脏胰岛素信号通路的认识水平,对于探寻干预脂肪肝的潜在靶点也具有一定的理论指导意义。 

  该研究获得了中科院、科技部以及基金委的经费支持。

Diabetologia:利拉鲁肽或可逆转胰岛素相关体重增加(ELEGANT研究)

对起始胰岛素治疗后体重显著增加的2型糖尿病患者而言,其最佳降血糖治疗方案仍不清楚。为此,来自荷兰内梅亨大学医学中心的Helena M. de Wit教授及其团队进行了一项研究,在胰岛素治疗后体重显著增加的2型糖尿病患者中,探讨加用胰高血糖素样肽–1(GLP–1)在维持血糖控制的同时,是否能逆转胰岛素相关体重增加,并与标准胰岛素治疗方案进行比较。该研究结果在线发表在2014月06月20日的Diabe

JAMA:2型糖尿病的胰岛素治疗:追求达标,还是改善结局?

美国一项研究回顾了目前正应用于门诊2型糖尿病患者治疗的胰岛素治疗方案,同时对1998年~2014年间胰岛素使用及用法方面的相关证据进行了评估。该研究发表于6月11日JAMA杂志糖尿病特刊。 研究结论指出,胰岛素治疗可帮助2型糖尿病患者达到理想的HbA1c目标值。大部分2型糖尿病患者的HbA1c目标可设定为7%,但当低血糖风险增加、存在其他共患病以及预期寿命缩短时,则应调整该目标。在糖尿病
