Iron death is a novel type of programmed cell death caused by excessive accumulation of iron-dependent lipid peroxidation products; however, the function of iron death during porcine oocyte maturation and embryo growth is poorly understood. This study was conducted to investigate the mechanism of ferric ammonium citrate (FAC) in regulating iron death in mature oocytes in vitro through the NRF2 signaling pathway, and subsequent embryonic development. The experiment was divided into four groups: 0 (control group), 2, 5, and 10 μM FAC. Western blotting (WB), reactive oxygen species (ROS)assays, mitochondrial membrane potential (MMP) assays, and Quantitative real-time polymerase chain reaction (qRT-PCR) were used to detect the maturation of porcine oocytes in vitro, the protein content of nuclear transcription factor E2-related factor 2 (Nrf2), the distribution of mitochondria, the level of oxidative stress, and the development of embryos fertilized in vitro. The results showed that with increasing FAC concentrations, the oocyte maturation rate in vitro, Nrf2 protein content, MMP, and cleavage rates of in vitro fertilized embryos decreased (significantly in the 5 μM group); the oxidative stress level was significantly increased; the transcript levels of Nrf2, GPX4, and FTH1 mRNAs were significantly decreased; the expression of ACSL4 was significantly upregulated (P < 0.05); and the blastocyst rate of embryos fertilized in vitro was reduced (significantly in the 2 μM group). In conclusion, FAC can regulate Nrf2 protein levels in porcine oocytes matured in vitro to induce iron death, affecting the maturation rate of oocytes, distribution of mitochondria, level of oxidative stress, expression of iron-death-related genes, and development of embryos after in vitro fertilization.
