Ciliary Assembly/Disassembly Assay in Non-transformed Cell Lines

[Abstract]  The primary cilium is a non-motile sensory organelle whose assembly and disassembly are closely associated with cell cycle progression. The primary cilium is elongated from the basal body in quiescent cells and is resorbed as the cells re-enter the cell cycle. Dysregulation of ciliary dynamics has been linked with ciliopathies and other human diseases. The in vitro serum-stimulated ciliary assembly/disassembly assay has gained popularity in addressing the functions of the protein-of-interest in ciliary dynamics. Here, we describe a well-tested protocol for transfecting human retinal ... [摘要]  主要纤毛是一种非运动感觉细胞器,其装配和拆卸与细胞周期进程密切相关。 初级纤毛在静止细胞中从基体拉长并随着细胞重新进入细胞周期而被吸收。 睫状动力失调与纤毛病和其他人类疾病有关。 体外血清刺激的睫状体装配/分解测定已经在解决睫状动力学中感兴趣的蛋白质的功能方面受到欢迎。 在这里,我们描述了转染人视网膜色素上皮细胞(RPE-1)和对转染细胞进行睫状体装配/分解测定的充分测试的方案。

【背景】初级纤毛是毛发样感觉细胞器,其在G 0 / G 1期出现,并且在细胞周期的S期之前分解(Tucker等, et al。,1979)。先前的研究已经证实,某些未转化的细胞类型(即,甚至是RPE-1细胞,3T3成纤维细胞和小鼠胚胎成纤维细胞[MEFs])可以被饿死以诱导静止和睫状体形成。随后的血清再次添加触发双相睫状体吸收,其在刺激后2小时和24小时达到峰值(Tucker等人,1979; Li等人,2011) 。该现象为文献中常用的血清刺激的睫状体组装/分解测定奠定了基础,以鉴定参与睫状体组装和拆卸的蛋白质(Pugacheva等人,2007; ...

Fatty Acid Content and Composition of Triacylglycerols of Chlorella kessleri

[Abstract]  Triacylglycerols (TAGs) are esters formed from one glycerol and three fatty acids. TAGs are induced to accumulate in algal cells under environmental stress conditions including nutrient-limitation, hyperosmosis, and low temperature, for the storage of metabolic energy and carbon, and also for the consumption of excess energy (e.g., Hirai et al., 2016; Hayashi et al., 2017). Beside their physiological significance, the commercial utilization of algal TAG has been expected for the production of biodiesel, the methyl esters of fatty acids, from the aspect of ... [摘要]  三酰甘油(TAG)是由一种甘油和三种脂肪酸形成的酯。在包括营养限制,高渗和低温在内的环境胁迫条件下,TAG被诱导积累在藻细胞中,用于代谢能和碳的储存以及多余能量的消耗(例如, Hirai等人,2016; Hayashi等人,2017)。除了它们的生理意义之外,从碳中性概念的角度来看,藻类TAG的商业利用已经被期望用于生产生物柴油,即脂肪酸的甲酯。 TAG的量可以通过定量测定其构成脂肪酸来确定。该方案由以下三部分组成:首先是根据Bligh和Dyer(1959)的方法,使用有机溶剂,氯仿和甲醇从藻细胞中提取总脂质,其次是TAG的分离通过薄层色谱法(TLC)从其他脂质类别中分离出来,第三种是产生其组成型脂肪酸的甲基酯化衍生物,随后通过毛细管气相色谱法(GLC)对其进行定量。该协议改编自Sato和Tsuzuki(2011),用于绿藻的TAG分析, Chlorella kessleri 。

【背景】已经使用几种方法测定TAG的脂肪酸含量。简单而方便的方案包括用脂肪酶处理将TAG转化成甘油,随后通过酶产生与产生颜色或荧光的探针反应的产物测量甘油含量(McGowan等人,1983; ...
