Abstract

Transposable elements (TEs) are highly expressed in preimplantation development. Preimplantation development is the phase when the cells of the early embryo undergo the first cell fate choice and change from being totipotent to pluripotent. A range of studies have advanced our understanding of TEs in preimplantation, as well as their epigenetic regulation and functional roles. However, many questions remain about the implications of TE expression during early development. Challenges originate first due to the abundance of TEs in the genome, and second because of the limited cell numbers in preimplantation. Here we review the most recent technological advancements promising to shed light onto the role of TEs in preimplantation development. We explore novel avenues to identify genomic TE insertions and improve our understanding of the regulatory mechanisms and roles of TEs and their RNA and protein products during early development.

技术拯救:如何揭示转座元件在植入前发育中的作用。
可转座元件(TE)在胚胎植入前的发育过程中高度表达。胚胎植入前发育是早期胚胎细胞进行第一次细胞命运选择并从全能细胞转变为多能细胞的阶段。一系列研究加深了我们对植入前发育过程中 TEs 及其表观遗传调控和功能作用的了解。然而,关于 TE 表达在早期发育过程中的影响仍存在许多问题。首先,基因组中存在大量 TE,其次,胚胎植入前的细胞数量有限,这些都是面临挑战的原因。在此,我们回顾了有望揭示 TE 在植入前发育中作用的最新技术进展。我们将探索识别基因组 TE 插入的新途径,加深我们对 TE 及其 RNA 和蛋白质产物在早期发育过程中的调控机制和作用的理解。
