Journal ArticleDOI
Supplementation of zinc on oocyte in vitro maturation improves preimplatation embryonic development in pigs.
Yubyeol Jeon,Junchul David Yoon,Lian Cai,Seon-Ung Hwang,Eunhye Kim,Zhong Zheng,Eunsong Lee,Dae-Young Kim,Sang-Hwan Hyun +8 more
TL;DR: Results indicate that treatment with adequate zinc concentrations during IVM improved the developmental potential of porcine embryos by regulating the intracellular GSH concentration, the ROS level, and transcription factor expression.
Journal ArticleDOI
Expression patterns of sirtuin genes in porcine preimplantation embryos and effects of sirtuin inhibitors on in vitro embryonic development after parthenogenetic activation and in vitro fertilization
TL;DR: Results suggest that sirtuins may have a physiological and important role in embryonic development of porcine preimplantation embryos by regulating essential gene expressions of developing embryos.
Journal ArticleDOI
Effects of coculture with cumulus-derived somatic cells on in vitro maturation of porcine oocytes.
Junchul David Yoon,Yubyeol Jeon,Lian Cai,Seon-Ung Hwang,Eunhye Kim,Eunsong Lee,Dae Y. Kim,Sang-Hwan Hyun +7 more
TL;DR: The results suggest that the presence of a population of 2.5 × 10(4) CSCs during IVM synergistically improved the developmental potential of IVF- and PA-derived porcine embryos by increasing the intracellular glutathione level via changing of a specific gene expression pattern during oocyte maturation.
Journal ArticleDOI
GDF8 activates p38 MAPK signaling during porcine oocyte maturation in vitro.
TL;DR: It is suggested that supplementation of GDF8 during IVM synergistically improved the developmental potential of IVF- and PA-derived porcine embryos by reducing the intracellular ROS level in oocytes by altering the transcription of specific genes and increasing the phosphorylation of p38 MAPK during IVm.
Journal ArticleDOI
Zinc deficiency during in vitro maturation of porcine oocytes causes meiotic block and developmental failure
Yubyeol Jeon,Junchul David Yoon,Lian Cai,Seon Ung Hwang,Eunhye Kim,Zhong Zheng,Eui-Bae Jeung,Eunsong Lee,Sang-Hwan Hyun +8 more
TL;DR: Zinc deficiency caused a meiotic block and had lasting effects on early embryonic development in pigs and is an essential element for successful oocyte maturation and embryonicdevelopment in pigs.
