Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR)-associated 9 (Cas9) system is the most efficient and widely used technology for genome editing in all sorts of organisms, including livestock animals. Here, we examined the feasibility of CRISPR/Cas9-derived genome editing (GE) in vitrified porcine zygotes, where the flexible planning of experiments in time and space is expected. OCT4 and CD46 genes were targeted, and the Cas9/sgRNA ribonucleoprotein complexes (RNP) were electroporated into zygotes at 2 h after warming. Vitrification or GE alone did not significantly reduce the developmental rates to the blastocyst stage. However, vitrification followed by GE significantly reduced blastocyst development. Sequencing analysis of the resultant blastocysts revealed efficient GE for both OCT4 (nonvitrified: 91.0%, vitrified: 95.1%) and CD46 (nonvitrified: 94.5%, vitrified: 93.2%), with no significant difference among them. Immunocytochemical analysis showed that GE-blastocysts lacked detectable proteins. They were smaller in size, and the cell numbers were significantly reduced compared with the control (p < 0.01). Finally, we demonstrated that double GE efficiently occurs (100%) when the OCT4-RNP and CD46-RNP are simultaneously introduced into zygotes after vitrification/warming. This is the first demonstration that vitrified porcine zygotes can be used in GE as efficiently as nonvitrified ones.

Lee M, Oh JN, Choe GC, Choi KH, Lee DK, Kim SH, Jeong J, Ahn Y, Lee CK. NANOG expression in parthenogenetic porcine blastocysts is required for intact lineage specification and pluripotency. Anim Biosci 2023; 36:1905-1917. [PMID: 37641830 PMCID: PMC10623019 DOI: 10.5713/ab.23.0210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/31/2023] [Accepted: 08/08/2023] [Indexed: 08/31/2023] Open
Abstract
OBJECTIVE Nanog homeobox (NANOG) is a core transcription factor that contributes to pluripotency along with octamer binding transcription factor-4 (OCT4) and sex determining region-Y box-2 (SOX2). It is an epiblast lineage marker in mammalian pre-implantation embryos and exhibits a species-specific expression pattern. Therefore, it is important to understand the lineage of NANOG, the trophectoderm, and the primitive endoderm in the pig embryo. METHODS A loss- and gain-of-function analysis was done to determine the role of NANOG in lineage specification in parthenogenetic porcine blastocysts. We analyzed the relationship between NANOG and pluripotent core transcription factors and other lineage makers. RESULTS In NANOG-null late blastocysts, OCT4-, SOX2-, and SOX17-positive cells were decreased, whereas GATA binding protein 6 (GATA6)-positive cells were increased. Quantitative real-time polymerase chain reaction revealed that the expression of SOX2 was decreased in NANOG-null blastocysts, whereas that of primitive endoderm makers, except SOX17, was increased. In NANOG-overexpressing blastocysts, caudal type homeobox 2 (CDX2-), SOX17-, and GATA6-positive cells were decreased. The results indicated that the expression of primitive endoderm markers and trophectoderm-related genes was decreased. CONCLUSION Taken together, the results demonstrate that NANOG is involved in the epiblast and primitive endoderm differentiation and is essential for maintaining pluripotency within the epiblast.

Improving the developmental competences of porcine parthenogenetic embryos by Notoginsenoside R1-induced enhancement of mitochondrial activity and alleviation of proapoptotic events. Reprod Domest Anim 2023; 58:1583-1594. [PMID: 37696770 DOI: 10.1111/rda.14474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 08/08/2023] [Accepted: 09/01/2023] [Indexed: 09/13/2023]
Abstract
Notoginsenoside R1 (NGR1), derived from the Panax notoginseng root and rhizome, exhibits diverse pharmacological influences on the brain, neurons, and osteoblasts, such as antioxidant effects, mitochondrial function protection, energy metabolism regulation, and inhibition of oxygen radicals, apoptosis, and cellular autophagy. However, its effect on early porcine embryonic development remains unclear. Therefore, we investigated NGR1's effects on blastocyst quality, reactive oxygen species (ROS) levels, glutathione (GSH) levels, mitochondrial function, and embryonic development-related gene expression in porcine embryos by introducing NGR1 during the in vitro culture (IVC) of early porcine embryos. Our results indicate that an addition of 1 μM NGR1 significantly increased glutathione (GSH) levels, blastocyst formation rate, and total cell number and proliferation capacity; decreased ROS levels and apoptosis rates in orphan-activated porcine embryos; and improved intracellular mitochondrial distribution, enhanced membrane potential, and reduced autophagy. In addition, pluripotency-related factor levels were elevated (NANOG and octamer-binding transcription factor 4 [OCT4]), antioxidant-related genes were upregulated (nuclear factor-erythroid 2-related factor 2 [NRF2]), and apoptosis- (caspase 3 [CAS3]) and autophagy-related genes (light chain 3 [LC3B]) were downregulated. These results indicate that NGR1 can enhance early porcine embryonic development by protecting mitochondrial function.

Maslinic Acid Supplementation during the In Vitro Culture Period Ameliorates Early Embryonic Development of Porcine Embryos by Regulating Oxidative Stress. Animals (Basel) 2023; 13:ani13061041. [PMID: 36978582 PMCID: PMC10044061 DOI: 10.3390/ani13061041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 03/03/2023] [Accepted: 03/05/2023] [Indexed: 03/17/2023] Open
Abstract
As a pentacyclic triterpene, MA exhibits effective free radical scavenging capabilities. The purpose of this study was to explore the effects of MA on porcine early-stage embryonic development, oxidation resistance and mitochondrial function. Our results showed that 1 μM was the optimal concentration of MA, which resulted in dramatically increased blastocyst formation rates and improvement of blastocyst quality of in vitro-derived embryos from parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT). Further analysis indicated that MA supplementation not only significantly decreased the abundance of intracellular reactive oxygen species (ROS) and dramatically increased the abundance of intracellular reductive glutathione (GSH) in porcine early-stage embryos, but also clearly attenuated mitochondrial dysfunction and inhibited apoptosis. Moreover, Western blotting showed that MA supplementation upregulated OCT4 (p < 0.01), SOD1 (p < 0.0001) and CAT (p < 0.05) protein expression in porcine early-stage embryos. Collectively, our data reveal that MA supplementation exerts helpful effects on porcine early embryo development competence via regulation of oxidative stress (OS) and amelioration of mitochondrial function and that MA may be useful for increasing the in vitro production (IVP) efficiency of porcine early-stage embryos.

Gene Expr Patterns 2022; 46:119285. [PMID: 36341977 DOI: 10.1016/j.gep.2022.119285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 10/02/2022] [Accepted: 10/24/2022] [Indexed: 11/04/2022]
Abstract
BCL2-like 10 (BCL2L10) is abundantly expressed in mammalian oocytes and plays a crucial role in the completion of oocyte meiosis. However, the expression patterns of BCL2L10 and its biological functions during preimplantation development have not been well characterized. Here, we investigated the spatiotemporal expressions of Bcl2l10 during mouse preimplantation development using RT-qPCR and immunofluorescence and its biological function using siRNA and morpholino injection into pronuclear embryos. Results from RT-qPCR showed that Bcl2l10 was highly expressed in the metaphase Ⅱ-stage oocytes and pronuclear-stage embryos, but expression markedly decreased from the two-cell stage onwards and was no longer detected at the four-cell stage and beyond. Immunofluorescence staining showed that BCL2L10 was detectable throughout preimplantation development and localized in the cytoplasm and nuclei. Knocking down Bcl2l10 resulted in a reduced blastocyst formation rate (P < 0.01) and decreased expression of OCT4, NANOG, and SOX17 (P < 0.05). We concluded that the role of BCL2L10 is strongly associated with developmental competence of preimplantation mouse embryos.
