ABSTRACT
Embryo implantation, the pivotal stage of gestation, is fundamentally dependent on synchronous embryonic development and uterine receptivity. In the early gestation period, the uterus and conceptus secrete growth factors, cytokines, and hormones to promote implantation. Circulating exosomal miRNAs are potential indicators of normal or complicated gestation. Our previous study revealed that pregnant sows' serum exosomes had upregulated miR-92b-3p expression compared to non-pregnant sows, and that the expression level progressively increased during early gestation. The present study's findings indicate that, compared to the ninth day of the estrous cycle (C9), pregnant sows had upregulated miR-92b-3p expression in the endometrium and embryos during the implantation stage ranging from day 9 to day 15 of gestation. Additionally, our results demonstrate that miR-92b-3p promotes the proliferation and migration of Porcine Trophoblast Cells (PTr2). Dual-Luciferase Reporter (DLR) gene assay, real-time fluorescent quantitative PCR (RT-qPCR), and Western blotting (WB) confirmed the bioinformatics prediction that phosphofructokinase-M (PFKM) serves as a target gene of miR-92b-3p. Notably, interference of PFKM gene expression markedly promoted PTr2 proliferation and migration. Furthermore, mice with downregulated uterine miR-92b-3p expression had smaller rates of successful embryo implantation. In summary, miR-92b-3p putatively modulates embryo implantation by promoting PTr2 proliferation and migration via its target gene PFKM.
