The effects of pretreatment with Cyclosporin A and Docetaxel before vitrification of porcine immature oocytes on subsequent embryo development. Reprod Biol 2023; 23:100798. [PMID: 37717489 DOI: 10.1016/j.repbio.2023.100798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/14/2023] [Accepted: 08/18/2023] [Indexed: 09/19/2023]
Abstract
In the present study, we attempted to improve the developmental competence of vitrified immature porcine oocytes by the preservation of mitochondrial properties using Cyclosporin A (CsA, inhibitor of mitochondrial membrane permeability transition) and Docetaxel (stabilizer of microtubules, hence mitochondrial distribution). In Experiment 1, Mitotracker red staining revealed reduced mitochondrial activity (MA) in vitrified/warmed oocytes at 0 and 22 h of in vitro maturation (IVM) compared with fresh ones. However, by at 46 h of IVM, MA levels in vitrified oocytes were similar to those in fresh control. Treatment of oocytes with CsA or Docetaxel improved MA at 0 h and 22 h of IVM compared with non-treated vitrified oocytes. However, there were no significant differences among groups in percentages of survival, maturation and embryo development after subsequent IVM and parthenogenetic activation. Nevertheless, a pretreatment with a combination of 10 µg/mL CsA and 0.05 µM Docetaxel improved the blastocyst formation of vitrified oocytes compared with non-treatment counterparts (11.2 ± 1.6% vs 5.9 ± 1.6%, P < 0.05). In conclusion, vitrification reduced mitochondrial activity in GV-stage oocytes during 0-22 h of IVM; however, it was normalized by 46 h IVM. Docetaxel or CsA pretreatment alone did not improve development competence of vitrified oocytes. However, pretreatment with a combination of CsA and Docetaxel could improve blastocyst formation rates.

Abstract
Fatty acids are not only widely known as energy sources, but also play important roles in many metabolic pathways. The significance of fatty acids in modulating the reproductive potential of livestock has received greater recognition in recent years. Functional fatty acids and their metabolites improve follicular development, oocyte maturation and embryo development, as well as endometrial receptivity and placental vascular development, through enhancing energy supply and precursors for the synthesis of their productive hormones, such as steroid hormones and prostaglandins. However, many studies are focused on the impacts of individual functional fatty acids in the reproductive cycle, lacking studies involved in deeper mechanisms and optimal fatty acid requirements for specific physiological stages. Therefore, an overall consideration of the combination and synergy of functional fatty acids and the establishment of optimal fatty acid requirement for specific stages is needed to improve reproductive potential in livestock.

Abstract
Elevated environmental temperatures can induce heat stress which could reduce fertility and early embryonic development. Fatty acids can initiate an endergonic reaction that absorbs cellular heat and decreases intracellular temperature. This study's objective was to minimize heat stress-induced damage to in vitro matured oocytes by supplementing maturation media with either 50 μM linoleic or linolenic acid or both (25 or 50 μM) during maturation at either 38.5 or 41.5°C. Oocytes were evaluated for intracellular antioxidative pathways, fertilization characteristics, or early embryonic development. Elevated maturation temperatures increased (p < 0.05) reactive oxygen species (ROS) formation and supplementation with linoleic or linolenic acid decreased (p < 0.05) ROS in oocytes matured at 41.5°C. Maturation temperature had an effect (p < 0.05) on the intracellular antioxidative pathways of the oocyte except for glutathione peroxidase activity. Regardless of maturation temperature, supplementation with linoleic or linolenic acid increased (p < 0.05) the enzyme activities and glutathione concentrations in the oocytes compared to no fatty acid supplementation. Supplementation of both linoleic and linolenic acid decreased (p < 0.05) polyspermic fertilization rates. Supplementing either 25 or 50 μM linoleic and linolenic acid to maturing oocytes at 41.5°C increased (p < 0.05) cleavage rates by 48 h after IVF and the blastocyst formation rates by 144 h after IVF compared to other treatments. Oocytes matured at 38.5°C had greater (p < 0.05) embryonic development than those matured at 41.5°C except for those supplemented with 50 μM linoleic and linolenic acid. Supplementing 50 μM linoleic and linolenic acid to the maturation medium of pig oocytes reduces the effects of heat stress-induced damage.

Abstract
PURPOSE To investigate whether fatty acid changes in granulosa cells (GCs) underly the pathogenic mechanisms of diminished ovarian reserve (DOR). METHODS GCs were obtained from patients with DOR (n = 70) and normal ovarian reserve (NOR, n = 70). Analysis of fatty acids changes in GCs was then analyzed. RESULTS Patients with DOR had significantly lower levels of antral follicle count and anti-Mullerian hormone and higher levels of follicle-stimulating hormone compared with NOR patients (P < 0.001). The good-quality embryo rate was notably decreased in DOR patients (51.99 vs 39.52%, P < 0.05). A total of 15 significantly decreased fatty acids in GCs from patients with DOR. The ATP levels were markedly lower in DOR patients than in NOR patients (39.07 ± 12.89 vs 23.21 ± 13.69%, P < 0.05). Mitochondrial membrane potential decreased in DOR patients (P < 0.01). In GCs from DOR patients, the β-oxidation genes (HADHA and ACSL) and DNA repair genes (PRKDC and RAD50) were significantly downregulated (P < 0.05). The γH2AX foci/nucleus ratio in DOR patients markedly increased relative to that of NOR patients (0.31 ± 0.03 vs 0.87 ± 0.07, P < 0.001). Meanwhile, the apoptosis rate of GCs was significantly higher in DOR patients (6.43 ± 2.11 vs 48.06 ± 6.72%, P < 0.01). CONCLUSION GC apoptosis resulting from the decrease of fatty acids, and associated with reduced ATP production and DNA damage, may contribute to the pathogenic mechanisms responsible for DOR.

Abstract
Recent researches reveal that during oocyte maturation, species-specific molecular profile exists, and has important functional roles. However, molecular differences between pig (a larger animal model for human reproduction) and human mature oocytes remain unknown. Here, by comparative transcriptome analyses of single cell RNA-seq data, we aimed to identify the common and unique maternal factors and associated biological processes between in vivo and in vitro matured pig oocytes, and between in vitro matured human and pig oocytes. Annotated protein coding mRNAs were identified in pig in vivo (11147) and in vitro (11997), and human in vitro (14491) MII oocytes, respectively. For in vivo and in vitro derived pig MII oocytes, 10551 annotated maternal mRNAs were common, mainly enriched in signaling pathways such as cell cycle, oocyte meiosis, microtubule cytoskeleton, MAPK, RNA processing/binding. Besides, in vivo (596) and in vitro (1446) pig MII-specific mRNAs and their involved signaling pathways (in vivo: Bmp, calcium-mediated signaling, PI3K-Akt; in vitro: growth factor activity, JAK-STAT, cytokine-cytokine receptor interaction, calcium signaling pathway) were also found. As for in vitro derived human and pig MII oocytes, 10285 annotated mRNAs were common, enriched in a variety of signaling pathways (cell cycle, oocyte meiosis, microtubule, AMPK, RNA splicing, protein serine/threonine kinase activity, etc). In vitro MII-specific mRNAs were found for humans (4206) and pigs (1712), which were also enriched in species-specific signaling pathways (humans: golgi related terms, transcription repressor and hormone activity; pigs: ATP biosynthetic process, G protein-coupled peptide receptor activity, animoacyl-tRNA biosynthesis), respectively. These findings improve our understanding on oocyte maturation, and also the limitations of pig model for human oocyte maturation and fertilization.

Abstract
PURPOSE The present study investigated the effects of docosahexaenoic acid (DHA) on the growth of bovine oocytes. METHODS Oocytes and granulosa cell complexes (OGCs) were collected from early antral follicles (0.4-0.7 mm) on the surface of ovaries harvested from a slaughterhouse. The OGCs were cultured with 0, 1, and 10 μmol/L docosahexanoic acid (DHA) for 16 days. RESULTS Antrum formation of the OGCs and the number of granulosa cells (GCs) surrounding the oocytes were comparable among groups, whereas supplementation of 0.1 μmol/L of DHA significantly improved oocyte growth. Oocytes grown with DHA had a higher fertilization rate, acetylation levels of H4K12, and ATP contents, as well as a lower lipid content compared with those grown without DHA. In addition, GCs surrounding OGCs grown with DHA had low lipid content compared with vehicle counterparts. Furthermore, when GCs were cultured in vitro, DHA increased ATP production, mitochondrial membrane potential, and reduced lipid content and levels of reactive oxygen species. RNA-seq of GCs revealed that DHA increased CPT1A expression levels and affect genes associated with focal adhesion, oxidative phosphorylation, and PI3K-AKT etc. CONCLUSION The results suggest that DHA supplementation affects granulosa cell characteristics and supports oocyte growth in vitro.

Abstract
This study was conducted to explore the molecular mechanisms of berberine (Ber) via peroxisome proliferator-activated receptor gamma (PPARG) in promoting in vitro maturation (IVM) and lipid metabolism of porcine oocytes. Our results showed that expression changes in PPARG influenced IVM and the lipid droplet content of porcine oocytes. Moreover, c-Jun-N-terminal kinase (JNK) inhibitor modified the effect of PPARG agonist on IVM and lipid droplet content of porcine oocytes, and Ber significantly reduced lipid droplet content. Activation of PPARG upregulated the transcription level of microRNA-192 (miR-192), significantly promoted the expression of fatty acid binding protein 3 (FABP3) and steroid regulatory element binding transcription factor 1 (SREBF1) and PPARG, inhibited phosphorylation of PPARG, and enhanced JNK phosphorylation. Ber and overexpression of miR-192 upregulated the transcription level of miR-192 in porcine oocytes; significantly decreased the expression of FABP3, SREBF1, and PPARG; increased PPARG phosphorylation; and inhibited JNK phosphorylation. Otherwise, JNK inhibitor reduced the effects of PPARG agonist. In conclusion, Ber may activate the expression of miR-192, downregulate the expression level of PPARG and lipid synthesis-related genes, increase PPARG phosphorylation, and reduce JNK phosphorylation to enhance lipid metabolism, which is beneficial to improve porcine oocyte quality of IVM.

Eicosapentaenoic acid supplemented to in vitro maturation medium results in lesser lipid content and intracellular reactive oxygen species in blastocysts of cattle. Anim Reprod Sci 2021; 229:106765.

Abstract
Sub-optimal cattle embryo development to the blastocyst stage still is a problem when conducting in vitro production (IVP) procedures. Supplementation of in vitro maturation (IVM) medium with omega 3-polyunsaturated eicosapentaenoic acid (EPA) is an approach that might have positive effects on lipid metabolism of cattle oocytes, potentially improving subsequent embryo development. The aim of this study was to evaluate effects of EPA addition to serum-free IVM medium on pronuclear formation after in vitro fertilization, cleavage, and blastocyst rates. Effects of EPA on lipid accumulation and intracellular reactive oxygen species (ROS) generation with IVP of cattle embryos was also investigated. In all experiments, cumulus-oocyte complexes were matured in IVM medium supplemented with 0 nM, 1 nM, or 1 μM EPA for 24 h. Pronuclear formation, cleavage, and blastocyst rates were similar for embryos when there was supplementation of EPA at all concentrations to those of the control group (P > 0.05). The inclusion of 1 nM EPA in medium resulted in a greater lipid content and less intracellular ROS in day 8-embryos compared with those of the Control group (P < 0.05). There were no differences, however, when there was inclusion of 1 μM EPA compared to embryos of the Control group at the day 8 developmental stage (P > 0.05). In conclusion, supplementation with IVM medium with the 1 nM EPA concentration resulted in a lesser blastocyst lipid and intracellular ROS concentration, without modifying embryo development, therefore, EPA could be a desirable supplement to improve embryo quality in cattle.

Abstract
Background The berberine (Ber) is an isoquinoline alkaloid compound extracted from Rhizoma coptidis and has the effect that reduces adipose. MicroRNA‐192 (miR‐192) is related to fat metabolism. However, the relevant mechanism of berberine on lipid metabolism during in vitro maturation (IVM) of porcine oocytes remains unclear. Objectives In this study, we investigated the molecular mechanism by which berberine promotes the IVM and lipid metabolism of porcine oocytes via miR‐192. Methods Ber was added to IVM medium of porcine oocytes. MiR‐192 agomir, miR‐192 antagomir and negative control fragment were microinjected into the cytoplasm of oocytes without Ber. Rates of oocyte IVM and embryonic development in each group were observed. The content of lipid droplets in IVM oocytes in each group was analyzed by Nile red staining. Expression levels of miR‐192 and FABP3, SREBF1 and PPARG, were detected by qPCR and western blotting. The target genes of miR‐192 were determined by luciferase reporter assays. Results and Conclusions We found that Ber significantly increased the rate of oocytes IVM and blastocyst development, and decreased the area and numbers of lipid droplets in IVM oocytes. Ber significantly increased the expression of miR‐192 in IVM oocytes, and significantly decreased the expression of SREBF1 and PPARG, which were target genes of miR‐192. This study indicates that Ber promotes lipid metabolism in porcine oocytes by activating the expression of miR‐192 and down‐regulating SREBF1 and PPARG, thus, improving IVM of porcine oocytes.

Abstract
Abstract
This paper presents the current possibilities, state of knowledge and prospects of in vitro production (IVP) of pig embryos, which consists of in vitro oocyte maturation, in vitro fertilization and in vitro embryo culture. In pigs, oocyte maturation is one of the most important stages in the embryo IVP process. It determines the oocyte’s fertilization ability as well as its embryonic development. Through many research studies of the proper selection of oocytes and appropriate maturation medium composition (especially the addition of various supplements), the in vitro maturation of pig oocytes has been significantly improved. Recent studies have demonstrated that modifications of the diluents and in vitro fertilization media can reduce polyspermy. Furthermore, several adjustments of the porcine culture media with the addition of some supplements have enhanced the embryo quality and developmental competence. These updates show the progress of IVP in pigs that has been achieved; however, many problems remain unsolved.

A Comparative Analysis of Oocyte Development in Mammals. Cells 2020; 9:cells9041002. [PMID: 32316494 PMCID: PMC7226043 DOI: 10.3390/cells9041002] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 04/06/2020] [Accepted: 04/09/2020] [Indexed: 12/11/2022] Open
Abstract
Sexual reproduction requires the fertilization of a female gamete after it has undergone optimal development. Various aspects of oocyte development and many molecular actors in this process are shared among mammals, but phylogeny and experimental data reveal species specificities. In this chapter, we will present these common and distinctive features with a focus on three points: the shaping of the oocyte transcriptome from evolutionarily conserved and rapidly evolving genes, the control of folliculogenesis and ovulation rate by oocyte-secreted Growth and Differentiation Factor 9 and Bone Morphogenetic Protein 15, and the importance of lipid metabolism.

Fatty acid metabolism as an indicator for the maternal-to-zygotic transition in porcine IVF embryos revealed by RNA sequencing. Theriogenology 2020; 151:128-136. [PMID: 32334121 DOI: 10.1016/j.theriogenology.2020.04.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 04/03/2020] [Accepted: 04/11/2020] [Indexed: 12/23/2022]
Abstract
A number of fatty acids have been found in porcine oocytes and early embryos. Recent studies have indicated the importance of fatty acids in the development of pre-implantation porcine embryos, whether derived from in vivo or somatic cell nuclear transfer. However, the effects of fatty acids on porcine embryos produced by in vitro fertilization (IVF) remain poorly defined. This study aimed to investigate the patterns of gene expression and functions of fatty acids in pre-implantation IVF porcine embryos at different stages using transcriptome sequencing. We found that, in IVF porcine embryos, genes related to fatty acid metabolism were positively expressed during early embryonic development. Additionally, the expression of genes related to lipid metabolism changed dramatically during the maternal-to-zygotic transition (MZT), and the genes associated with lipid metabolism were correlated with zygotic genome activation in porcine IVF embryos, suggesting that fatty acid metabolism plays an important role in MZT. In summary, fatty acid metabolism may be an indicator of MZT in porcine IVF embryos, which presents new considerations for exploring the regulatory mechanisms of this process.
