Image-Based Analysis of Mitochondrial Area and Counting from Adult Mouse Dopaminergic Neurites

[Abstract]  Mitochondria form dynamic cytoplasmic networks which undergo morphological changes in order to adapt to cellular stresses and signals. These changes can include alterations in size and number within a given cell. Analysis of the whole network can be a useful metric to assess overall mitochondrial health, particularly in neurons, which are highly sensitive to mitochondrial dysfunction. Here we describe a method which combines immunofluorescence and computerized image analysis to measure mitochondrial morphology (quantification of number, density, and area) in dopaminergic neurites of mice ... [摘要]  线粒体形成动态细胞质网络,其经历形态变化以适应细胞应激和信号。 这些变化可以包括给定单元内的大小和数量的改变。 分析整个网络可以是评估整体线粒体健康的有用指标,特别是在对线粒体功能障碍高度敏感的神经元中。 在这里,我们描述了一种方法,它结合免疫荧光和计算机图像分析,以测量表达线粒体靶向eYFP的小鼠的多巴胺能神经突的线粒体形态(数量,密度和面积的量化)。

【背景】 线粒体是存在于每个复杂生物的基本上所有细胞中的双膜细胞器。它们的主要功能是提供大部分细胞能量作为ATP,但它们也在细胞凋亡,缓冲细胞内Ca 2 + ,活性氧物质产生和膜电位调节中发挥作用(Neupert和Herrmann, 2007; Hamanaka和Chandel,2010; Shutt和McBride,2013)。

这些细胞器通常被描述为单个“豆状”结构,实际上是动态细胞质网络的组成部分。它们可以经历由膜融合和裂变的动态过程调节的主要形态变化,该过程被认为涉及通过称为线粒体自噬的过程消除功能障碍的细胞器。线粒体网络也可以作为对高细胞能量需求的响应而增加(Sheng,2017; Devine和Kittler,2018)。线粒体网络的形态可以根据不同的应激源而改变,并且存在多种可能的形态,即细胞类型,甚至细胞室依赖性(Picard et al。,2013 ...

Protocol for the Preparation of Arabidopsis Meiotic Chromosome Spreads and Fluorescent in situ Hybridization

[Abstract]  This protocol is a more detailed version of previous protocols (Yang et al., 2011; Bolaños-Villegas et al., 2013) developed for the examination of meiotic chromosome spreads. Meiotic chromosome spreads are useful to determine the presence of defects in chromosome pairing and segregation. The protocol also describes how to perform fluorescent in situ hybridization experiments with a centromere probe used to label chromosomes. [摘要]  该方案是为研究减数分裂染色体扩散而开发的以前方案的更详细的版本(Yang等人,2011;Bolaños-Villegas等人,2013)。 减数分裂染色体扩散可用于确定染色体配对和分离中缺陷的存在。 该方案还描述了如何使用用于标记染色体的着丝粒探针进行荧光原位杂交实验。
