Abstract
The objective of this study was to minimise polyspermic penetration by increasing the perivitelline space (PVS) thickness through supplementation of the hyaluronic acid components glucuronic acid and N-acetyl-d-glucosamine (GlcNAc). Oocytes (n=4690) were supplemented during the first 24h and/or the remainder of maturation (final 16-18h) with 0.01mM glucuronic acid and 0.01mM GlcNAc and then evaluated for PVS thickness, hyaluronic acid, glutathione and glutathione peroxidase concentrations. Fertilised oocytes were evaluated for polyspermic penetration and embryo development. The PVS thickness and amount of hyaluronic acid was significantly (P<0.05) greater in oocytes supplemented with 0.01mM glucuronic acid and 0.01mM GlcNAc during the second part or all of maturation compared with the other treatments. In addition, polyspermic penetration was significantly (P<0.05) less in oocytes supplemented with 0.01mM glucuronic acid and 0.01mM GlcNAc during the second part or all of maturation compared with the other treatments. Supplementing 0.01mM glucuronic acid and GlcNAc during maturation significantly (P<0.05) increased the percentage of cleaved embryos by 48h after IVF and blastocysts formed by 144h after IVF compared those not supplemented. These results indicate that supplementing PVS components during maturation decreases polyspermic penetration by increasing PVS thickness.

Abstract
Simple Summary Hyaluronic acid, also known as hyaluronan, is essential for the expansion of cumulus cells, the maturation of oocytes, and further embryo development. This study aimed to examine the effects of treatment with glucuronic acid and N-acetyl-D-glucosamine, which are components of hyaluronic acid, during porcine oocyte in vitro maturation and embryonic development after parthenogenetic activation and somatic cell nuclear transfer. We measured the diameter of mature oocytes, the thickness of the perivitelline space, the intracellular reactive oxygen species level, and the expression of cumulus cell expansion genes and reactive oxygen species-related genes and examined the cortical granule reaction of oocytes after electrical activation. In conclusion, the addition of 0.05 mM glucuronic acid and 0.05 mM N-acetyl-D-glucosamine and during the initial 22 h of in vitro maturation in pig oocytes has beneficial effects on cumulus expansion, perivitelline space thickness, cytoplasmic maturation, reactive oxygen species level, cortical granule exocytosis, and early embryonic development after parthenogenesis and somatic cell nuclear transfer. Glucuronic acid and N-acetyl-D-glucosamine can be applied to in vitro production technology and can be used as ingredients to produce high-quality porcine blastocysts. Abstract This study aimed to examine the effects of treatment with glucuronic acid (GA) and N-acetyl-D-glucosamine (AG), which are components of hyaluronic acid (HA), during porcine oocyte in vitro maturation (IVM). We measured the diameter of the oocyte, the thickness of the perivitelline space (PVS), the reactive oxygen species (ROS) level, and the expression of cumulus cell expansion and ROS-related genes and examined the cortical granule (CG) reaction of oocytes. The addition of 0.05 mM GA and 0.05 mM AG during the first 22 h of oocyte IVM significantly increased oocyte diameter and PVS size compared with the control (non-treatment). The addition of GA and AG reduced the intra-oocyte ROS content and improved the CG of the oocyte. GA and AG treatment increased the expression of CD44 and CX43 in cumulus cells and PRDX1 and TXN2 in oocytes. In both the chemically defined and the complex medium (Medium-199 + porcine follicular fluid), oocytes derived from the GA and AG treatments presented significantly higher blastocyst rates than the control after parthenogenesis (PA) and somatic cell nuclear transfer (SCNT). In conclusion, the addition of GA and AG during IVM in pig oocytes has beneficial effects on oocyte IVM and early embryonic development after PA and SCNT.

Cyanidin improves oocyte maturation and the in vitro production of pig embryos. In Vitro Cell Dev Biol Anim 2020; 56:577-584. [PMID: 32754855 DOI: 10.1007/s11626-020-00485-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Accepted: 07/16/2020] [Indexed: 12/18/2022]
Abstract
The objective of this study was to reduce the negative effects of oxidative stress by decreasing the levels of reactive oxygen species (ROS) through supplementation of the major antioxidants present in elderberries: kuromanin and cyanidin. Oocytes (n = 1150) were supplemented with 100 or 200 μM of kuromanin or cyanidin during maturation, and then evaluated for ROS levels or fertilized and evaluated for penetration, polyspermic penetration, male pronucleus formation, and embryonic development. The ROS levels and incidence of polyspermic penetration were lower (P < 0.05) in oocytes supplemented with 100 μM cyanidin when compared with other treatments. Supplementation of 100 μM cyanidin increased (P < 0.05) MPN and blastocyst formation compared with other treatments. However, supplementation of 100 μM kuromanin did not have significant effects on the criteria evaluated, and supplementation of 200 μM kuromanin had significant (P < 0.05) detrimental effects for each criterion. Additional oocytes (n = 1438) were supplemented with 100 μM cyanidin during maturation and evaluated for glutathione, glutathione peroxidase, catalase, and superoxide dismutase activity. Supplementation of 100 μM cyanidin increased (P < 0.05) catalase activity and intracellular GSH levels compared with no supplementation of cyanidin. These results indicate that supplementing cyanidin during maturation reduces oxidative stress by reducing ROS levels and increasing GSH concentrations within the oocyte.
