Maternal factor Trim75 contributes to zygotic genome activation program in mouse early embryos

Mol Biol Rep. 2024 Apr 20;51(1):560. doi: 10.1007/s11033-024-09349-0.

Abstract

Background: Zygotic genome activation (ZGA) is an important event in the early embryo development, and human embryo developmental arrest has been highly correlated with ZGA failure in clinical studies. Although a few studies have linked maternal factors to mammalian ZGA, more studies are needed to fully elucidate the maternal factors that are involved in ZGA.

Methods and results: In this study, we utilized published single-cell RNA sequencing data from a Dux-mediated mouse embryonic stem cell to induce a 2-cell-like transition state and selected potential drivers for the transition according to an RNA velocity analysis.

Conclusions: An overlap of potential candidate markers of 2-cell-like-cells identified in this research with markers generated by various data sets suggests that Trim75 is a potential driver of minor ZGA and may recruit EP300 and establish H3K27ac in the gene body of minor ZGA genes, thereby contributing to mammalian preimplantation embryo development.

Keywords: Trim75; Mouse; Preimplantation embryo development; ZGA.
