ATAC-seq is a high-throughput technology that defines and quantifies chromatin accessibility by analyzing Tn5 transposase enzymes. ATAC-seq is used to map chromatin accessibility genome-wide and to identify regions of transcription-factor binding and nucleosome position. As such, ATAC-seq is a new generation tool used in biomedical research to measure and articulate the pathogenesis of major diseases, to demonstrate the pharmacology of current drugs, and to guide the development of new drugs and the function of biomarkers. In this review, we summarize the current applications and advantages of ATAC-seq, and define its prospective contributions related to the regulatory mechanism of gene expression to identify and manage complex disease while elucidating and guiding future research references and strategies.
染色质转座酶可及性测序(assay for transposase-accessible chromatin with high-throughput sequencing,ATAC-seq)是利用Tn5转座酶研究染色质可及性的高通量测序技术。ATAC-seq可以在全基因组范围内绘制染色质可及性图谱,揭示转录因子结合位点以及核小体的位置。在医学领域,ATAC-seq技术是研究重大疾病发病机制、药物作用机制、新药研发和生物标志物功能等的新一代有力工具。本文对ATAC-seq技术的优势及其在复杂疾病研究中的应用和前景进行了综述,以期为人类复杂疾病基因表达调控机制等相关研究的开展提供借鉴与参考。.
