Abstract

Long non-coding RNAs (lncRNAs) have been identified as key regulators of gene expression and participate in many vital physiological processes. Chromatin remodeling, being an important epigenetic modification, has been identified in many biological activities as well. However, the regulatory mechanism of lncRNA in chromatin remodeling remains unclear. In order to characterize the genome-wide lncRNA expression and their potential interacting factors during this process in , we investigated the expression pattern of lncRNAs and mRNAs based on the transcriptome analyses and found significant differences between lncRNAs and mRNAs. Then, we performed TSA-FISH experiments of candidate lncRNAs and their potential interactors that have different functions in embryos to determine their expression pattern. In addition, we also analyzed the expression of transposable elements (TEs) and their interactors to explore their expression in mutants. Our results provide a new perspective for understanding the possible regulatory mechanism of lncRNAs and TEs as well as their targets in chromatin remodeling.

摘要

长非编码 RNA(lncRNA)已被确定为基因表达的关键调节剂,并参与许多重要的生理过程。染色质重塑作为一种重要的表观遗传修饰,也在许多生物活动中被发现。然而,lncRNA 在染色质重塑中的调控机制尚不清楚。为了描述在这一过程中 lncRNA 的全基因组表达及其潜在的相互作用因子,我们基于转录组分析研究了 lncRNA 和 mRNA 的表达模式,发现 lncRNA 和 mRNA 之间存在显著差异。然后,我们对候选 lncRNA 及其在 胚胎中有不同功能的潜在相互作用因子进行 TSA-FISH 实验,以确定它们的表达模式。此外,我们还分析了转座元件(TEs)及其相互作用因子的表达,以探索它们在 突变体中的表达。我们的研究结果为理解 lncRNA 和 TEs 及其在染色质重塑中的靶标作为可能的调控机制提供了新的视角。
