Definitions

  • the present application relates to the field of biotechnology, and in particular to the use of an agent for knocking down or inhibiting SLC35F6 in the preparation of a drug for activating AMPK.
  • AMPK Addenosine 5'-monophosphate (AMP)-activated protein kinase
  • AMPK is an AMP-dependent protein kinase, a key molecule for regulating biological energy metabolism. It is a protein molecule widely present in animal and plant cells and is the core of the study of diabetes and other metabolism-related diseases. It is expressed in various metabolism-related organs and can be activated by various stimuli in the body, including cell stress, exercise, and many hormones and substances that can affect cell metabolism.
  • AMPK can sense the level of ATP in cells. When mitochondria are inhibited and low energy supply is provided, AMPK phosphorylates specific enzymes and sites, increases ATP production, and reduces ATP consumption, thereby restoring energy balance.
  • AMPK is the most important kinase in metabolic regulation. When there is a lack of energy in the cell, AMPK is activated by phosphorylation by upstream kinases, and then phosphorylates many key enzymes and control proteins in metabolism, promotes catabolism, inhibits anabolism, increases the accumulation of ATP, and provides energy for cells.
  • the traditional view is that the activation of AMPK is due to the increase in the concentration of intracellular AMP, which binds to the ⁇ subunit of AMPK, changes the conformation of the AMPK heterotrimer, and enables the T172 site of its ⁇ subunit to be phosphorylated by the upstream kinase LKB1, thereby activating the AMPK holoenzyme.
  • AMPK can be activated on lysosomes, and its lysosomal localization depends on the myristoylation modification of the second glycine of the AMPK ⁇ subunit.
  • AMPK on lysosomes can also respond to changes in the concentration of FBP (fructose-1,6-bisphosphate), a secondary product of sugar metabolism. It is still unknown what proteins on lysosomes regulate AMPK activity and whether these proteins can serve as potential drug targets to affect AMPK activity.
  • FBP fructtose-1,6-bisphosphate
  • the regulatory mechanisms based on existing AMPK activators are mainly focused on increasing the phosphorylation of AMPK ⁇ , and the regulatory sites involved are already saturated. There is currently no mechanism for AMPK dephosphorylation to explore and discover AMPK inhibitors and activators.
  • the purpose of the present application is to overcome the deficiencies of the prior art and provide the use of a reagent for knocking down or inhibiting SLC35F6 in the preparation of a drug for activating AMPK.
  • the technical solution adopted by this application is: the application of SLC35F6 in the preparation of AMPK activity inhibitors.

Studies have shown that AMPK on lysosomes can sense changes in secondary products of sugar metabolism, which is different from the regulation of AMPK activity in the whole cell. Therefore, there should be new AMPK regulatory proteins on lysosomes that can more directly regulate AMPK activity.
  • This application uses BiFC and proximity labeling technology to discover that the SLC35F6-ALPP complex inhibits the activity of AMPK on lysosomes, and the ligand UDP-GlcNAc of SLC35F6 can relieve the inhibition of AMPK by the SLC35F6-ALPP complex, thereby activating AMPK and exerting therapeutic effects.

Description

敲低或抑制SLC35F6的试剂在制备激活AMPK的药物中的应用 技术领域
本申请涉及生物技术领域,具体涉及敲低或抑制SLC35F6的试剂在制备激活AMPK的药物中的应用。
背景技术
AMPK(Adenosine 5‘-monophosphate(AMP)-activated protein kinase)即AMP依赖的蛋白激酶,是生物能量代谢调节的关键分子,广泛存在在动物和植物细胞中的蛋白质分子,是研究糖尿病及其他代谢相关疾病的核心。它表达于各种代谢相关的器官中,能被机体各种刺激激活,包括细胞压力、运动和很多激素及能影响细胞代谢的物质。AMPK作为一种营养和能量传感器,它可以感知细胞内ATP的水平高低。当线粒体被抑制,低能量供应条件下,AMPK磷酸化特异性的酶和位点,增加ATP生成,降低ATP消耗,以此来恢复能量平衡。
AMPK是代谢调节中最重要的激酶,当细胞内能量缺乏时,AMPK被上游激酶磷酸化激活,进而磷酸化许多代谢中的关键酶以及控制蛋白,促进分解代谢,抑制合成代谢,增加ATP的积累,为细胞提供能量。传统观点认为,AMPK的激活是由于细胞内AMP的浓度上升,与AMPK的γ亚基结合,改变AMPK异源三聚体的构象,使其α亚基的T172位点能够被上游激酶LKB1磷酸化,进而激活AMPK全酶。近年来的研究发现,AMPK的激活在不同的亚细胞区域并不一致,AMPK能够在溶酶体上激活,其溶酶体定位依赖于AMPKβ亚基的第二位甘氨酸的豆蔻酰化修饰。另外,除了响应AMP,溶酶体上的AMPK还能响应糖代谢次级产物FBP(果糖-1,6-二磷酸)的浓度变化。溶酶体上调控AMPK活性的蛋白,以及这些蛋白是否能够作为潜在的药物靶点,影响AMPK的活性,现在还不得而知。
现有的AMPK激活剂基于的调控机制主要集中在增加AMPKα的磷酸化,所涉及的调控位点已经饱和。目前还没有针对AMPK去磷酸化的机制,去探索和发现AMPK抑制剂和激活剂。
发明内容
本申请的目的在于克服现有技术的不足,提供敲低或抑制SLC35F6的试剂在制备激活AMPK的药物中的应用。
为实现上述目的,本申请采取的技术方案为:SLC35F6在制备AMPK活性抑制剂中的应用。本申请的目的在于探索AMPK的溶酶体激活机制,进而发现新的AMPK活性调控蛋白。研究显示,溶酶体上的AMPK在能够感受糖代谢次级产物的变化,不同于整个细胞中的AMPK活性调控。所以,溶酶体上应该存在新的AMPK调节蛋白,能够更加直接的调控AMPK活性。本申请利用BiFC和临近标记技术,发现了SLC35F6-ALPP复合体在溶酶体上抑制AMPK的活性,而SLC35F6的配体UDP-GlcNAc能够解除SLC35F6-ALPP复合体对AMPK的抑制,进而激活AMPK,发挥疗效。

以下通过实施例形式的具体实施方式,对本申请的上述内容再作进一步的详细说明。但不应将此理解为本申请上述主题的范围仅限于以下的实例。凡基于本申请上述内容所实现的技术均属于本申请的范围。
实施例1
本实施例通过实验验证敲低SLC35F6对AMPK活性的影响,具体实验步骤如下:
(1)将生长状态良好的HEK293T细胞加入六孔板中,于37℃,5%CO2培养;
(2)将终浓度为100nM对照siRNA(由广州锐博生物提供,货号#siN0000001-1-5)、100nM用于敲低SLC35F6的实验组siRNA分别与10ul的 RNAimax试剂、200ul的optimen混匀,得混合液;所述实验组siRNA的序列分别为:
实验组一(#1):5′-GCAUGGUGUUGGACAGCUU-3′(SEQ ID NO:1);
实验组二(#2):5′-GCAUUGCCUUCUUCAACUU-3′(SEQ ID NO:2);
实验组三(#3):5′-GAGGAGAAGUUCGUCUACA-3′(SEQ ID NO:3)。
(3)将混合液室温静置20min后,加入六孔板的HEK293T细胞中,6小时后更换新鲜培养基;48h后,收集并裂解细胞,1000gx10min离心,收集上清,并提取蛋白。
(4)免疫印迹检测:将步骤(3)得到的蛋白进行聚丙烯酰胺凝胶电泳,电泳参数为:恒压80V,20min加上120v,45min,然后恒流0.2A,1h转膜,5%脱脂牛奶封闭1h;用一抗p-AMPK,AMPK,SLC35F6,tubulin孵育过夜,第二天再敷育对应的二抗,检测相应蛋白的表达水平。
实验结果如图1所示。p-AMPK(T172)表明AMKP的磷酸化程度,代表AMPK的活性。由图1可知看出,实验组没有表达SLC35F6,说明实验组成功敲低SLC35F6;对照组的p-AMPK的表达低于实验组,说明敲低SLC35F6后AMPK被激活。

实验组三(#3):5′-CGGUCCUCCUAUACGGAAA-3′(SEQ ID NO:6)。
(3)将混合液室温静置20min后,加入六孔板的HEK293T细胞中,6小时后更换新鲜培养基;48h后,收集并裂解细胞,1000gx10min离心,收集上清,并提取蛋白。
(4)免疫印迹检测:将步骤(3)得到的蛋白进行聚丙烯酰胺凝胶电泳,电泳参数为:恒压80V,20min加上120v,45min,然后恒流0.2A,1h转膜,5%脱脂牛奶封闭1h;用一抗p-AMPK,AMPK,p-ACC1,ACC1,ALPP,tubulin孵育过夜,第二天再敷育对应的二抗,检测相应蛋白的表达水平。
实验结果如图2所示。由图2可知看出,实验组没有表达ALPP,说明实验组成功敲低ALPP;对照组的p-AMPK的表达低于实验组,说明敲低ALPP后AMPK被激活。
实施例3
本实施例通过实验验证降低SLC35F6和ALPP的相互作用对AMPK活性的影响,具体实验步骤如下:
(1)将生长状态良好的HEK293T细胞加入六孔板中,于37℃,5%CO2培养;采用PEI将Flag-SLC35F6和GST-ALPP顺转入HEK293T细胞,6小时后换液;
(2)48h后,裂解细胞,在细胞裂解液中加入UDP-GlcNAc孵育1h;
(3)2h后在裂解液中加入GST beads,旋转孵育2小时;
(4)beads沉淀后,用裂解液洗涤三次;
(5)采用免疫印迹检测细胞系裂解液和免疫沉淀后beads中GST,p-AMPK,AMPK,tubulin的水平。
实验结果如图3所示。Flag和GST代表过表达的Flag-SLC35F6和GST-ALPP。5%input组里面,代表总的含量,IP组里面,代表免疫共沉淀下拉下来的成分,IP/Input的比值越高,代表相互结合越强。由图3可知,相比于Veh的对照组(仅含有1X PBS),UDP-GlcNAc的加入使得p-AMPK增加,表明UDP-GlcNAc能够提升AMPK的活性(对比第二泳道和第三泳道)。同时,UDP-GlcNAc能够降低GST磁珠免疫沉淀GST-ALPP过后的Flag-SLC35F6,表明UDP-GlcNAc能够降低GST-ALPP和Flag-SLC35F6的相互作用。综上,UDP-GlcNAc能够通过降低SLC35F6和ALPP的相互作用,进而提升AMPK的活性。
实施例4
本实施例验证敲低SLC35F6联合常规AMPK激活剂对AMPK活性的影响,具体实验步骤如下:
(1)将生长状态良好的HEK293T细胞加入六孔板中,于37℃,5%CO2培养;
(2)将终浓度为100nM对照siRNA、100mM用于敲低SLC35F6的实验组siRNA分别与10ul的RNAimax试剂、200ul的optimen混匀,得混合液;
(3)将混合液室温静置20min后,加入六孔板的HEK293T细胞中,6小时后更换新鲜培养基;
(4)48h后,分别进行饥饿处理:使用无葡萄糖培养基代替正常培养基16h、双氧水处理:正常培养的细胞中加入浓度为1mM的H2O2,5min、AICAR处理:正常培养的细胞中加入AMPK激活剂2mMAICAR4h;
(5)收集并裂解细胞,1000gx10min离心,收集上清,并提取蛋白;
(6)将蛋白进行免疫印迹检测:聚丙烯酰胺凝胶电泳,电泳参数:恒压80V,20min加上120v,45min,然后恒流0.2A,1h转膜,5%脱脂牛奶封闭1h;用一抗p-AMPK,AMPK,p-ACC1,ACC1,SLC35F6,tubulin孵育过夜,第二天再敷育对应的二抗,检测相应蛋白的表达水平。
结果如图4~6所示。由图4~6可知,采用常规AMPK激活剂(如葡萄糖饥饿16小时,双氧水处理5分钟,AMP类似物AICAR处理4小时)都能够提升AMPK的磷酸化(对比第一泳道和第二泳道)。敲低SLC35F6联合常规AMPK激活剂,能在本来已经激活的AMPK基础上更近一步激活(对比第二泳道和第四泳道),由此表明敲低SLC35F6与常规AMPK激活剂联用能够更好的提升AMPK的活性。
