Mmu-miR-126a-3p plays a role in murine embryo implantation by regulating Itga11.
miR-126a-3p has been found to be specifically up-regulated in the process of murine embryo implantation. This study aimed to further clarify the role of miR-126a-3p in embryo implantation. The expression of miR-126a-3p in implantation sites was significantly higher than that in interimplantation sites (P = 0.009). ⋯ Loss of function of miR-126a-3p significantly reduced the number of implantation sites in vivo (P = 0.013). Collectively, miR-126a-3p may play a major role in embryo implantation by regulating Itga11, possibly through impairing cell migratory and invasive capacity. These findings should contribute to a better understanding of the miRNA-based mechanism of embryo implantation.
