摘要: 染色质开放性是指核小体或转录因子等蛋白与真核生物染色质DNA结合后,对其他蛋白能否再结合的开放程度,这一特性能够反映转录活性。染色质结构是动态变化的,染色质开放性与动物生长发育、细胞分化等过程密切相关,基因组开放染色质高效精准定位可为解析基因表达调控机制提供重要线索。本文介绍染色质开放性检测方法、染色质开放性的影响因素,重点阐述染色质开放性与动物发育的关系并对其发展及应用前景进行阐述,以期为动物发育基因表达调控等相关研究提供参考依据。

Abstract: Chromatin accessibility refers to the openness of proteins such as nucleosomes or transcription factors to the recombination of other proteins after binding to eukaryotic chromatin DNA, which can reflect transcriptional activity. Open chromatin is closely related to animal growth and development, cell differentiation and other processes. The efficient and accurate localization of open chromatin in the genome can provide vital clues for exploring the regulation mechanism of gene expression. In this paper, the methods of chromatin accessibility detection and the factors of chromatin accessibility are introduced, and the effects of chromatin accessibility on animal development and its development and application prospects are discussed so as to provide a reference for related studies on gene expression regulation during animal development.

Key words: chromatin accessibility, epigenetics, gene expression, embryonic development
