Abstract

Understanding a remarkable event at the start of life, the oocyte-to-embryo transition (OET), has remained elusive, especially in humans. Using newly developed techniques, Liu et al. showed that human maternal mRNAs undergo global poly(A) tail-mediated remodeling during OET, identified the enzymes involved, and demonstrated the essentiality of remodeling for embryo cleavage.

Keywords: PAIso-seq; human; oocyte-to-embryo transition (OET); poly(A) tail; post-transcriptional regulation.
