ABSTRACT
Despite being the predominant genetic elements in mammalian genomes, retrotransposons were often dismissed as genomic parasites with ambiguous biological significance. However, recent studies reveal their functional involvement in early embryogenesis, encompassing crucial processes such as zygotic genome activation (ZGA) and cell fate decision. This review underscores the paradigm shift in our understanding of retrotransposon roles during early preimplantation development, as well as their rich functional reservoir that is exploited by the host to provide cis-regulatory elements, noncoding RNAs, and functional proteins. The rapid advancement in long-read sequencing, low input multiomics profiling, advanced in vitro systems, and precise gene editing techniques encourages further dissection of retrotransposon functions that were once obscured by the intricacies of their genomic footprints.
