[Abstract]  As one of the main energy metabolism organs, kidney has been proved to have high energy requirements and are more inclined to fatty acid metabolism as the main energy source. Long-chain acyl-CoA dehydrogenases (LCAD) and beta-hydroxyacyl-CoA dehydrogenase (beta-HAD), key enzymes involved in fatty acid oxidation, has been identified as the substrate of acetyltransferase GCN5L1 and deacetylase Sirt3. Acetylation levels of LCAD and beta-HAD regulate its enzymes activity and thus affect fatty acid oxidation rate. Moreover, immunoprecipitation is a key assay for the detection of LCAD and beta-HAD acetylation levels. Here we describe a protocol of immunoprecipitation of acetyl-lysine and western blotting of LCAD and beta-HAD in palmitic acid treated HK-2 cells (human renal tubular epithelial ... [摘要]  [摘要] 甲作为肾脏的主要能量代谢器官之一,肾脏已被证明具有很高的能量需求,并且更倾向于将脂肪酸代谢为主要能量来源。 长链酰基辅酶A脱氢酶(LCAD)和Beta-羟酰基 -CoA脱氢酶(β-HAD),涉及的关键酶脂肪酸氧化,已被确定为乙酰转移酶GCN5L1和脱乙酰酶Sirt3的底物。 LCAD和β-HAD的乙酰化水平调节其酶的活性,从而影响脂肪酸的氧化速率。 此外,免疫沉淀是检测LCAD和β-HAD乙酰化水平的关键方法。在这里,我们描述了在棕榈酸处理的HK-2细胞(人肾小管上皮细胞)中乙酰赖氨酸的免疫沉淀以及LCAD和β-HAD的免疫印迹实验。 该方案为读者提供了清晰的步骤,因此该方法可用于检测各种蛋白质的乙酰化水平。

[背景 ] 翻译后修饰(PT Ms)使细胞具有高度动态的机制来调节细胞途径(Zhao 等,2010)。 乙酰化已成为主要的翻译后蛋白质修饰之一。越来越多的证据小号指示乙酰化对手磷酸化的线粒体调控修改(Henriksen的等人,2012) 。 过线粒体蛋白质的60%被乙酰化,作为声明,这是参与能量代谢例如三羧酸(TCA)循环,氧化磷酸化(OXPHOS),脂肪酸氧化和氨基酸代谢(Hirschey 等人,2010 ; ...

[Abstract]  This protocol provides an easy and rapid method to prepare lipopolysaccharide from the gastric pathogen Helicobacter pylori for visualization on acrylamide gels by silver staining and for detecting the presence of Lewis antigens by Western blot. The silver staining is a four-step procedure, involving a 20 min-oxidation step, a 10 min-silver staining step, a 2-10 min color development step and finally a 1-min color termination step. Lipopolysaccharide from H. pylori wild-type and corresponding mutants analyzed by this method are described in a recent publication (Li et al., 2017). This crude preparation of LPS for silver staining is also applicable in other Gram-negative bacteria. [摘要]  该方案提供了一种从胃病原幽门螺杆菌制备脂多糖的简便快速方法,用于通过银染显示丙烯酰胺凝胶,并通过Western印迹检测Lewis抗原的存在。 银染是四步法,包括20分钟氧化步骤,10分钟银染色步骤,2-10分钟显色步骤,最后是1分钟颜色终止步骤。 来自H的脂多糖。 在最近的出版物(Li等人,2017)中描述了通过该方法分析的野生型和相应的突变体的幽门螺杆菌。 这种用于银染的LPS的粗制剂也适用于其他革兰氏阴性细菌。
【背景】脂多糖(LPS)是一种大而可变的复合糖脂,其组成了大多数革兰氏阴性细菌外膜的外叶。 它通常由三个结构域组成:称为脂质A(或内毒素)的疏水结构域,其嵌入外膜中; 相对保守的非重复核 - 低聚糖; 和从细胞延伸到外部环境的可变O-抗原。 H的独特功能。 幽门螺杆菌脂多糖O抗原是模拟人Lewis抗原的岩藻糖基化寡糖结构的存在。 从革兰氏阴性细菌大规模提取高纯度的LPS是劳动密集型和耗时的。 在这里,在这个协议中,我们详细地描述了使用来自胃病原幽门螺杆菌的容易和快速的粗制备制剂用于通过银染和Lewis抗原通过蛋白质印迹进行表达。
