    Evaluation of the Efficiency of Genome Editing Tools by a Frameshift Fluorescence Protein Reporter
    Authors:  Balaji T. Moorthy, Akhilesh Kumar, Lauren X. Lotenfoe and Fangliang Zhang, date: 05/20/2020, view: 136, Q&A: 0
    [Abstract] In the last decade, genome editing has been the center of attention as a novel tool for mechanistic investigations and for potential clinical applications. Various genome editing tools like meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector-based nucleases (TALEN), and the clustered regularly interspaced short ...
    ChIP-Seq from Limited Starting Material of K562 Cells and Drosophila Neuroblasts Using Tagmentation Assisted Fragmentation Approach
    Authors:  Junaid Akhtar, Piyush More and Steffen Albrecht, date: 02/20/2020, view: 455, Q&A: 0
    [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 ...
    Enhanced-ice-COLD-PCR for the Sensitive Detection of Rare DNA Methylation Patterns in Liquid Biopsies
    Authors:  Florence Mauger and Jörg Tost, date: 12/05/2019, view: 1002, Q&A: 0
    [Abstract] In the context of precision medicine, the identification of novel biomarkers for the diagnosis of disease, prognosis, predicting treatment outcome and monitoring of treatment success is of great importance. The analysis of methylated circulating-cell free DNA provides great promise to complement or replace genetic markers for these applications, ...
    DNase I Chromatin Accessibility Analysis
    Authors:  Brook S. Nepon-Sixt and Mark G. Alexandrow, date: 12/05/2019, view: 916, Q&A: 0
    [Abstract] Chromatin consists of compacted DNA in complex with proteins and contributes to the organization of DNA and its stability. Furthermore, chromatin plays key roles in regulating cellular processes such as DNA replication, transcription, DNA repair, and mitosis. Chromatin assumes more compact (inaccessible) or decondensed (accessible) conformations ...
    SIRF: A Single-cell Assay for in situ Protein Interaction with Nascent DNA Replication Forks
    Authors:  Sunetra Roy and Katharina Schlacher, date: 09/20/2019, view: 1402, Q&A: 0
    [Abstract] The duplication of DNA is a fundamental process that is required for the transfer of the genetic information from parent to daughter cells. Aberrant DNA replication processes are associated with diverse disease phenotypes, including developmental defects, ageing disorders, blood disorders such as Fanconi Anemia, increased inflammation and cancer. ...
    Minigene Assay to Evaluate CRISPR/Cas9-based Excision of Intronic Mutations that Cause Aberrant Splicing in Human Cells
    Authors:  David J. Sanz and Patrick T. Harrison, date: 06/05/2019, view: 1627, Q&A: 0
    [Abstract] The construction of Hybrid minigenes provides a robust and simple strategy to study the effects of disease-causing mutations on mRNA splicing when biological material from patient cells is not available. Hybrid minigenes can be used as splicing reporter plasmids allow RNA expression and heterologous splicing reactions between synthetic splicing ...
    A Functionally Robust Phenotypic Screen that Identifies Drug Resistance-associated Genes Using 3D Cell Culture
    Authors:  Sun-Young Lee and Mina J. Bissell, date: 11/20/2018, view: 2545, Q&A: 0
    [Abstract] Drug resistance is a major obstacle in cancer treatment: A case in point is the failure of cancer patients to respond to tyrosine kinase inhibitors (TKI) of EGFR, a receptor that is highly expressed in many cancers. Identification of the targets and delineation of mechanisms of drug resistance remain major challenges. Traditional pharmacological ...
    Generation of Gene Knockout and Gene Replacement with Complete Removal of Full-length Endogenous Transcript Using CRISPR-Trap
    Authors:  Jonas Mechtersheimer, Stefan Reber and Marc-David Ruepp, date: 10/20/2018, view: 3291, Q&A: 0
    [Abstract] This protocol describes the application of the CRISPR-Trap from designing of the gene targeting strategy to validation of successfully edited clones that was validated on various human cell lines, among them human induced pluripotent stem cells (hiPSCs). The advantage of CRISPR-Trap over conventional approaches is the complete removal of any ...
    Quantitative ChIP-seq by Adding Spike-in from Another Species
    Authors:  Kongyan Niu, Rui Liu and Nan Liu, date: 08/20/2018, view: 5888, Q&A: 0
    [Abstract] Chromatin immunoprecipitation followed by sequencing (ChIP-seq) is a routine procedure in the lab; however, epigenome-wide quantitative comparison among independent ChIP-seq experiments remains a challenge. Here, we contribute an experimental protocol combined with a computational workflow allowing quantitative and comparative assessment of ...
    Centromere Chromosome Orientation Fluorescent in situ Hybridization (Cen-CO-FISH) Detects Sister Chromatid Exchange at the Centromere in Human Cells
    Author:  Simona Giunta, date: 04/05/2018, view: 4392, Q&A: 0
    [Abstract] Human centromeres are composed of large tandem arrays of repetitive alpha satellite DNA, which are often sites of aberrant rearrangement in cancers (Mitelman et al., 1997; Padilla-Nash et al., 2001). To date, annotation of the human centromere repetitive sequences remains incomplete, greatly hindering in-depth functional studies ...
