Abstract
Luteolin (Lut), a polyphenolic compound that belongs to the flavone subclass of flavonoids, possesses anti-inflammatory, cytoprotective, and antioxidant activities. However, little is known regarding its role in mammalian oocyte maturation. This study examined the effect of Lut supplementation during in vitro maturation (IVM) on oocyte maturation and subsequent developmental competence after somatic cell nuclear transfer (SCNT) in pigs. Lut supplementation significantly increased the proportions of complete cumulus cell expansion and metaphase II (MII) oocytes, compared with control oocytes. After parthenogenetic activation or SCNT, the developmental competence of Lut-supplemented MII oocytes was significantly enhanced, as indicated by higher rates of cleavage, blastocyst formation, expanded or hatching blastocysts, and cell survival, as well as increased cell numbers. Lut-supplemented MII oocytes exhibited significantly lower levels of reactive oxygen species and higher levels of glutathione than control MII oocytes. Lut supplementation also activated lipid metabolism, assessed according to the levels of lipid droplets, fatty acids, and ATP. The active mitochondria content and mitochondrial membrane potential were significantly increased, whereas cytochrome c and cleaved caspase-3 levels were significantly decreased, by Lut supplementation. These results suggest that Lut supplementation during IVM improves porcine oocyte maturation through the reduction of oxidative stress and mitochondria-mediated apoptosis.

Abstract
Histone modifications play important roles in regulating the expression of developmental genes during preimplantation embryonic development. Here, we analyzed the temporal and spatial distribution of the acetylation and mono-, di- and tri-methylations of noncanonical histone H3 at lysine 23 (H3K23ac, H3K23me1, H3K23me2 and H3K23me3) during porcine oocyte maturation and pre-implantation development, as well as in porcine fetal fibroblasts. H3K23ac, -me1, -me2 and -me3 were enhanced in EdU-positive fetal fibroblasts (S-phase) compared to EdU-negative fetal fibroblasts (G1 and/or G2-phase). More than 91% of the DNA replication foci were well colocalized with H3K23 methylation sites in porcine fetal fibroblasts. H3K23ac and -me3 were detectable through oocyte meiotic resumption. After parthenogenic activation (PA), H3K23me3 was very weakly detected in the pronuclei of zygotes and the nuclei of blastocysts. After in vitro fertilization (IVF), no H3K23me3 signal was observed in the nuclei of IVF-derived embryos, with the exception of the residual polar bodies. In contrast, H3K23ac signals were clearly detected in the nuclei of PA- and IVF-derived blastocysts. The RNA polymerase inhibitor, actinomycin D, reduced the H3K23ac signal in porcine blastocysts. These findings may serve as a valuable reference for further studies of how H3K23 modifications contribute to the regulation of oocyte maturation and early embryonic development in mammals.

Abstract
Ganglioside GT1b is well-known for its role in cytokine production and in activating epidermal growth factor receptor (EGFR)-mediated signaling pathways in cancer cells. However, there are no reports that clearly elucidate the role of GT1b in EGFR-mediated signaling pathways in porcine oocytes during the process of in vitro maturation (IVM). In this study, we investigated the role of GT1b in EGFR-mediated activation of the ERK1/2 pathway in porcine cumulus-oocyte complexes (COCs) at 44 h of IVM. Our data show that expression of the ST3GAL2 protein significantly increased in porcine COCs at 44 h irrespective of treatment with EGF. Meiotic maturation and mRNA levels of factors (HAS2, TNFAIP6, and PTX3) related to cumulus cell expansion significantly increased in COCs treated with 2 μM GT1b during IVM in the absence of EGF. They also increased in COCs treated with EGF/GT1b as compared to that in the other groups. Interestingly, protein levels of EGFR, phospho-EGFR, ERK1/2, and phospho-ERK1/2 dramatically increased in COCs treated with EGF/GT1b. Moreover, the rate of fertilization and the developmental competence of blastocyst were significantly higher in EGF/GT1b-treated COCs. Taken together, these results suggest that exogenous GT1b improves meiotic maturation and cumulus cell expansion in porcine COCs via activation of EGFR-mediated ERK1/2 signaling.
