摘 要:摘 要:全基因组筛选是系统性分析基因组的有力工具,可在全基因组范围内发现具有特定生物学功能的基因或DNA 元件。基于CRISPR/Cas9 基因编辑技术的全基因组筛选具有高通量和高效率的特点,已被广泛应用于疾病机理和药物开发等研究,为临床治疗提供科学用药依据。同时,CRISPR/Cas9 筛选可靶向启动子、增强子和长链非编码RNA 等序列,解析其调控基因表达的功能。此外,将全基因组筛选与单细胞测序技术结合,可揭示细胞转录组差异,剖析基因功能关系。
Abstract: Abstract: Whole-genome screen is a powerful tool for genetic studies and can be used to identify novel genes that contribute to special biological phenotypes. Recently, a high-throughput and efficient screen based on CRISPR/Cas9 genome-editing has been applied to study the mechanisms underlying human diseases and discover new potential drug targets. Meanwhile, CRISPR/Cas9 screen can specifically target promoters, enhancers and long non-coding RNAs to uncover new class of cis-regulatory factors or non-protein coding genes. In addition, a combination of CRISPR/Cas9 screen and single cell RNA sequencing allows us to capture transcriptome variation and genetic interactions in detail.
