PRDM14, a member of the PRDM family protein, plays an important role in the regulation of epigenetic reprogramming. Knockdown of Prdm14 in germ cells can lead to female and male subfertility, and the function of PRDM14 appears to be conserved across mammalian species. Thus, we analyzed the expression of Prdm14 in parthenogenetic embryos at all stages of preimplantation and then evaluated the effect of Prdm14 downregulation on porcine parthenogenetic embryonic development. We found that Prdm14 transcripts are highly expressed in the metaphase II (MII) oocyte, and their level gradually increased from the 2-cell to 8-cell stage and slightly declined at the blastocyst stage during the development of parthenogenetic porcine embryos. Prdm14 was knocked down in oocytes at the MII stage by the injection of siRNA to assess the role of this protein in epigenetic remodeling and embryo development. Prdm14 knockdown significantly decreased the cleavage and blastocyst rates without changing the total cell number of the blastocysts. In addition, the expression levels of the antiapoptotic gene BCL-2 and the pluripotency-related genes OCT4 and SOX2 were also significantly decreased. These results showed that PRDM14 could affect embryonic development through regulating the expression levels of the pluripotency and antiapoptotic genes during the development of parthenogenetically activated porcine embryos.
