Fig. 4: CRISPR screen analysis tools identify CREs with varying selectivity. a, sgRNA-mediated growth effects (blue), H3K27ac ChIP signal (pink) and DHS (gray) for a CRISPRi growth screen at the GATA1 locus. sgRNAs were filtered to remove any low-specificity sgRNAs (GuideScan aggregated...
通过在K562细胞中进行的分析,研究确立了利用CRISPR干扰(CRISPR interference, CRISPRi)筛选内源性非编码元件的指南,包括准确检测显示变化且通常效应低的CREs的能力。 此外,研究通过比较五种筛选分析工具(benchmarking five screen analysis tools),发现CASA在CRE调用方面最为保守,且能有效抵御低特异性sgRNA引起的假象。 研...

guiding patient selection, and identifying targets and pathways for potential combination therapies. CRISPRi comes into its own for modeling druggability and validating hits from a KO screen, and CRISPRa supports the understanding of drug-gene interactions. ...
CRISPRAnalyzeR uses a guided-analysis approach. This means you will be guided through the analysis. CRISPAnalyzeR consists of four sections: Screen and Sequencing Quality Estimation Hit Calling using multiple published hit calling algorithms Hit Confirmation which includes information from up to 26 extern...

(Fig.1A). Deep sequencing and MAGeCK analysis were used to analyze the distribution of the sgRNA library in the surviving cells (Fig.1B). The screen identifiedMUC21as the top-ranked NK cell evasion mechanism. Additionally, we observed significant enrichment of sgRNAs targeting carcinoembryonic ...

To perform CRISPR screening using GC-based cell sorting, it is necessary to determine what to screen as the target positive phenotype and train the machine classifier using training samples. The design and preparation of positive and negative phenotypes in the step of training classifiers are the ...
After editing the targeted cells at the genomic level, it is highly necessary to screen the edited cells to assess the off-target effects and their intronic or exonic impact. Many computational high-throughput genome sequencing (NGS)-based in vivo and in vitro tools have been designed to ...
