    [Abstract] Chromatin immunoprecipitation is extensively used to investigate the epigenetic profile and transcription factor binding sites in the genome. However, when the starting material is limited, the conventional ChIP-Seq approach cannot be implemented. This protocol describes a method that can be used to generate the chromatin profiles from as low as ...
    Mapping the Mechanome–A Protocol for Simultaneous Live Imaging and Quantitative Analysis of Cell Mechanoadaptation and Ingression
    力学组学映射—一种用于同时进行实时成像和细胞力学适应和侵入定量分析的方案
    [Abstract] Mechanomics, the mechanics equivalent of genomics, is a burgeoning field studying mechanical modulation of stem cell behavior and lineage commitment. Analogous to mechanical testing of a living material as it adapts and evolves, mapping of the mechanome necessitates the development of new protocols to assess changes in structure and function in ...
    Isolation and Quantification of Metabolite Levels in Murine Tumor Interstitial Fluid by LC/MS
    LC/MS法对小鼠肿瘤间质液中代谢产物的分离和定量

    [Abstract] Cancer is a disease characterized by altered metabolism, and there has been renewed interest in understanding the metabolism of tumors. Even though nutrient availability is a critical determinant of tumor metabolism, there has been little systematic study of the nutrients directly available to cancer cells in the tumor microenvironment. Previous ...
    Probabilistic Models for Predicting Mutational Routes to New Adaptive Phenotypes
    用于预测新的适应性表型突变路径的概率模型
    作者:Eric Libby and Peter A. Lind日期:10/20/2019,浏览量:806,Q&A: 0
    [Abstract] Understanding the translation of genetic variation to phenotypic variation is a fundamental problem in genetics and evolutionary biology. The introduction of new genetic variation through mutation can lead to new adaptive phenotypes, but the complexity of the genotype-to-phenotype map makes it challenging to predict the phenotypic effects of ...
    Non-aqueous Fractionation (NAF) for Metabolite Analysis in Subcellular Compartments of Arabidopsis Leaf Tissues
    非水体系分离(NAF)用于拟南芥叶组织亚细胞组分的代谢研究
    作者:David B. Medeiros, Stéphanie Arrivault, Jessica Alpers, Alisdair R. Fernie and Fayezeh Arabi日期:10/20/2019,浏览量:624,Q&A: 0
    [Abstract] The accurate determination of metabolite distribution in subcellular compartments is still challenging in plant science. Various methodologies, such as fluorescence resonance energy transfer-based technology, nuclear magnetic resonance spectroscopy and protoplast fractionation allow the study of metabolite compartmentation. However, large changes ...
    Electron Microscopy Sample Preparation Protocol Enabling Nano-to-mesoscopic Mapping of Cellular Connectomes and Their Habitats in Human Tissues and Organs
    通过电镜样品制备实现的人体组织和器官中细胞连接体及其定位的纳米与介观图谱分析
    作者:Lucy Ngo, Anton D. Nathanson, Tomasz Garbowski, Ulf Knothe, Dirk Zeidler and Melissa L. Knothe Tate日期:07/20/2019,浏览量:1539,Q&A: 0
    [Abstract] Multibeam scanning electron microscopy (multiSEM) provides a technical platform for seamless nano-to-mesoscale mapping of cells in human tissues and organs, which is a major new initiative of the U.S. National Institutes of Health. Such cross-length-scale imaging is expected to provide unprecedented understanding of relationships between cellular ...
    A Protocol to Map the Spatial Proteome Using HyperLOPIT in Saccharomyces cerevisiae
    利用HyperLOPIT绘制酿酒酵母空间蛋白质组图谱的方法

    [Abstract] The correct subcellular localization of proteins is vital for cellular function and the study of this process at the systems level will therefore enrich our understanding of the roles of proteins within the cell. Multiple methods are available for the study of protein subcellular localization, including fluorescence microscopy, organelle ...
    Genome-wide Estimation of Evolutionary Distance and Phylogenetic Analysis of Homologous Genes
    进化距离的全基因组评估和同源基因的系统进化分析
    作者:Meixia Zhao, Biao Zhang, Jianxin Ma and Damon Lisch日期:12/05/2018,浏览量:2638,Q&A: 0
    [Abstract] Homologous genes, including paralogs and orthologs, are genes that share sequence homologies within or between different species. Homologous genes originate from a common origin through speciation, genetic duplication or horizontal gene transfer. Estimation of the sequence divergence of homologous genes help us to understand divergence time, which ...
    Use of Gas Chromatography to Quantify Short Chain Fatty Acids in the Serum, Colonic Luminal Content and Feces of Mice
    利用气相色谱法定量分析小鼠血清、结肠管腔内容物和粪便中短链脂肪酸
    [Abstract] Short-Chain Fatty Acids (SCFAs) are a product of the fermentation of resistant starches and dietary fibers by the gut microbiota. The most important SCFA are acetate (C2), propionate (C3) and butyrate (C4). These metabolites are formed and absorbed in the colon and then transported through the hepatic vein to the liver. SCFAs are more concentrated ...
    Stable-isotope Labeled Metabolic Analysis in Drosophila melanogaster: From Experimental Setup to Data Analysis

    [Abstract] Stable-isotope labeled metabolic analysis is an essential methodology to characterize metabolic regulation during biological processes. However, the method using stable-isotope-labeled tracer (e.g., 13C-glucose) in live animal is only beginning to be developed. Here, we contribute a qualitative metabolic labeling experiment ...
