Wei Y, Wang J, Qu R, Zhang W, Tan Y, Sha Y, Li L, Yin T. Genetic mechanisms of fertilization failure and early embryonic arrest: a comprehensive review. Hum Reprod Update 2024; 30:48-80. [PMID: 37758324 DOI: 10.1093/humupd/dmad026] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 07/07/2023] [Indexed: 10/03/2023] Open
Abstract
BACKGROUND Infertility and pregnancy loss are longstanding problems. Successful fertilization and high-quality embryos are prerequisites for an ongoing pregnancy. Studies have proven that every stage in the human reproductive process is regulated by multiple genes and any problem, at any step, may lead to fertilization failure (FF) or early embryonic arrest (EEA). Doctors can diagnose the pathogenic factors involved in FF and EEA by using genetic methods. With the progress in the development of new genetic technologies, such as single-cell RNA analysis and whole-exome sequencing, a new approach has opened up for us to directly study human germ cells and reproductive development. These findings will help us to identify the unique mechanism(s) that leads to FF and EEA in order to find potential treatments. OBJECTIVE AND RATIONALE The goal of this review is to compile current genetic knowledge related to FF and EEA, clarifying the mechanisms involved and providing clues for clinical diagnosis and treatment. SEARCH METHODS PubMed was used to search for relevant research articles and reviews, primarily focusing on English-language publications from January 1978 to June 2023. The search terms included fertilization failure, early embryonic arrest, genetic, epigenetic, whole-exome sequencing, DNA methylation, chromosome, non-coding RNA, and other related keywords. Additional studies were identified by searching reference lists. This review primarily focuses on research conducted in humans. However, it also incorporates relevant data from animal models when applicable. The results were presented descriptively, and individual study quality was not assessed. OUTCOMES A total of 233 relevant articles were included in the final review, from 3925 records identified initially. The review provides an overview of genetic factors and mechanisms involved in the human reproductive process. The genetic mutations and other genetic mechanisms of FF and EEA were systematically reviewed, for example, globozoospermia, oocyte activation failure, maternal effect gene mutations, zygotic genome activation abnormalities, chromosome abnormalities, and epigenetic abnormalities. Additionally, the review summarizes progress in treatments for different gene defects, offering new insights for clinical diagnosis and treatment. WIDER IMPLICATIONS The information provided in this review will facilitate the development of more accurate molecular screening tools for diagnosing infertility using genetic markers and networks in human reproductive development. The findings will also help guide clinical practice by identifying appropriate interventions based on specific gene mutations. For example, when an individual has obvious gene mutations related to FF, ICSI is recommended instead of IVF. However, in the case of genetic defects such as phospholipase C zeta1 (PLCZ1), actin-like7A (ACTL7A), actin-like 9 (ACTL9), and IQ motif-containing N (IQCN), ICSI may also fail to fertilize. We can consider artificial oocyte activation technology with ICSI to improve fertilization rate and reduce monetary and time costs. In the future, fertility is expected to be improved or restored by interfering with or supplementing the relevant genes.

Abstract
Medulloblastoma (MB) is a heterogeneous group of malignant pediatric brain tumors, divided into molecular groups with distinct biological features and prognoses. Currently available therapy often results in poor long-term quality of life for patients, which will be afflicted by neurological, neuropsychiatric, and emotional sequelae. Identifying novel therapeutic agents capable of targeting the tumors without jeopardizing patients' quality of life is imperative. Rosmarinic acid (RA) is a plant-derived compound whose action against a series of diseases including cancer has been investigated, with no side effects reported so far. Previous studies have not examined whether RA has effects in MB. Here, we show RA is cytotoxic against human Daoy (IC50 = 168 μM) and D283 (IC50 = 334 μM) MB cells. Exposure to RA for 48 h reduced histone deacetylase 1 (HDAC1) expression while increasing H3K9 hyperacetylation, reduced epidermal growth factor (EGFR) expression, and inhibited EGFR downstream targets extracellular-regulated kinase (ERK)1/2 and AKT in Daoy cells. These modifications were accompanied by increased expression of CDKN1A/p21, reduced expression of SOX2, and a decrease in proliferative rate. Treatment with RA also reduced cancer stem cell markers expression and neurosphere size. Taken together, our findings indicate that RA can reduce cell proliferation and stemness and induce cell cycle arrest in MB cells. Mechanisms mediating these effects may include targeting HDAC1, EGFR, and ERK signaling, and promoting p21 expression, possibly through an increase in H3K9ac and AKT deactivation. RA should be further investigated as a potential anticancer agent in experimental MB.

Abstract
Dynamic epigenetic regulation is critical for proper oogenesis and early embryo development. During oogenesis, fully grown germinal vesicle oocytes develop to mature Metaphase II oocytes which are ready for fertilization. Fertilized oocyte proliferates mitotically until blastocyst formation and the process is called early embryo development. Throughout oogenesis and early embryo development, spatio-temporal gene expression takes place, and this dynamic gene expression is controlled with the aid of epigenetics. Epigenetic means that gene expression can be altered without changing DNA itself. Epigenome is regulated through DNA methylation and histone modifications. While DNA methylation generally ends up with repression of gene expression, histone modifications can result in expression or repression depending on type of modification, type of histone protein and its specific residue. One of the modifications is histone acetylation which generally ends up with gene expression. Histone acetylation occurs through the addition of acetyl group onto amino terminal of the core histone proteins by histone acetyltransferases (HATs). Contrarily, histone deacetylation is associated with repression of gene expression, and it is catalyzed by histone deacetylases (HDACs). This review article focuses on what is known about alterations in the expression of HATs and HDACs and emphasizes importance of HATs and HDACs during oogenesis and early embryo development.

Abstract
The biology of preimplantation embryo gene expression began 56 years ago with studies of the effects of protein synthesis inhibition and discovery of changes in embryo metabolism and related enzyme activities. The field accelerated rapidly with the emergence of embryo culture systems and progressively evolving methodologies that have allowed early questions to be re-addressed in new ways and in greater detail, leading to deeper understanding and progressively more targeted studies to discover ever more fine details. The advent of technologies for assisted reproduction, preimplantation genetic testing, stem cell manipulations, artificial gametes, and genetic manipulation, particularly in experimental animal models and livestock species, has further elevated the desire to understand preimplantation development in greater detail. The questions that drove enquiry from the earliest years of the field remain drivers of enquiry today. Our understanding of the crucial roles of oocyte-expressed RNA and proteins in early embryos, temporal patterns of embryonic gene expression, and mechanisms controlling embryonic gene expression has increased exponentially over the past five and a half decades as new analytical methods emerged. This review combines early and recent discoveries on gene regulation and expression in mature oocytes and preimplantation stage embryos to provide a comprehensive understanding of preimplantation embryo biology and to anticipate exciting future advances that will build upon and extend what has been discovered so far.

Abstract
More research is being conducted on myocardial cell treatments utilizing stem cell lines that can develop into cardiomyocytes. All of the forms of cardiac illnesses have shown to be quite amenable to treatments using embryonic (ESCs) and induced pluripotent stem cells (iPSCs). In the present study, we reviewed the differentiation of these cell types into cardiomyocytes from an epigenetic standpoint. We also provided a miRNA network that is devoted to the epigenetic commitment of stem cells toward cardiomyocyte cells and related diseases, such as congenital heart defects, comprehensively. Histone acetylation, methylation, DNA alterations, N6-methyladenosine (m6a) RNA methylation, and cardiac mitochondrial mutations are explored as potential tools for precise stem cell differentiation.

Abstract
In mammals, E2 factor (E2F) acts as a cell cycle regulator. E2F transcription factor 4 (E2F4) is a member of the E2F family of transcription factors and usually represents predominant E2F activity in cells. The E2F4 gene has been extensively studied in animals and is associated with multiple functions, such as cell cycle regulation and apoptosis; however, little is known about its role during embryonic development. In this study, we investigated the function of E2F4 and its mechanism of action in porcine embryo development. For this purpose, we knocked down E2F4 by microinjecting double-stranded RNA of E2F4 at the 1-cell stage. The results showed that E2F4 knockdown in porcine embryos led to a significant decrease in the blastocyst rate and total cell number. Defective E2F4 expression reduced the level of G1/S checkpoints (cyclin E-cyclin-dependent kinase 2) and cell cycle-related gene expression at the 4-cell embryo stage and blastocyst. Moreover, a decrease in E2F4 expression increased phosphorylated H2A.X variant histones and activated ataxia telangiectasia mutated (ATM) and p53-p21 pathway. In addition, E2F4 depletion caused a significant decrease in histone acetylation. Taken together, E2F4 plays a critical role as a transcriptional activator in the development of porcine embryos, an observation that contradicts its well-established role as a transcription repressor.

Abstract
Acetylation is a key post-translational modification (PTM) involved in the regulation of both histone and non-histone proteins. It controls cellular processes such as DNA transcription, RNA modifications, proteostasis, aging, autophagy, regulation of cytoskeletal structures, and metabolism. Acetylation is essential to maintain neuronal plasticity and therefore essential for memory and learning. Homeostasis of acetylation is maintained through the activities of histone acetyltransferases (HAT) and histone deacetylase (HDAC) enzymes, with alterations to these tightly regulated processes reported in several neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Both hyperacetylation and hypoacetylation can impair neuronal physiological homeostasis and increase the accumulation of pathophysiological proteins such as tau, α-synuclein, and Huntingtin protein implicated in AD, PD, and HD, respectively. Additionally, dysregulation of acetylation is linked to impaired axonal transport, a key pathological mechanism in ALS. This review article will discuss the physiological roles of protein acetylation and examine the current literature that describes altered protein acetylation in neurodegenerative disorders.

Abstract
The basic units of chromatin are nucleosomes, that are made up of DNA wrapped around histone cores. Histone lysine residue is a common location for posttranslational modifications, with acetylation being the second most prevalent. Histone acetyltransferases (HATs/KATs) and histone deacetylases (HDACs/KDACs) regulate histone acetylation, which is important in gene expression control. HDACs/KDACs regulate gene expressions through the repression of the transcription machinery. HDAC/KDAC isoforms play a major role during various stages of embryo development and neurogenesis. In specific, class I and II HDACs/KDACs are involved in cardiac muscle differentiation and development. An insight into different pathways and genes associated with embryonic development, the effect of HDAC/KDAC activity during the embryonic stem cell differentiation, preimplantation, embryo development, gastrulation, and the role of different HDAC/KDAC inhibitors during the process of embryogenesis is summarized in the present review article.

Abstract
Epigenome reprogramming after fertilization enables transcriptionally quiescent maternal and paternal chromatin to acquire a permissive state for subsequent zygotic genome activation (ZGA). H3K27 acetylation (H3K27ac) is a well-established chromatin marker of active enhancers and promoters. However, reprogramming dynamics of H3K27ac during maternal-to-zygotic transition (MZT) in mammalian embryos are not well-studied. By profiling the allelic landscape of H3K27ac during mouse MZT, we show that H3K27ac undergoes three waves of rapid global transitions between oocyte stage and 2-cell stage. Notably, germinal vesicle oocyte and zygote chromatin are globally hyperacetylated, with noncanonical, broad H3K27ac domains that correlate with broad H3K4 trimethylation (H3K4me3) and open chromatin. H3K27ac marks genomic regions primed for activation including ZGA genes, retrotransposons, and active alleles of imprinted genes. We show that CBP/p300 and HDAC activities play important roles in regulating H3K27ac dynamics and are essential for preimplantation development. Specifically, CBP/p300 acetyltransferase broadly deposits H3K27ac in zygotes to induce the opening of condensed chromatin at putative enhancers and ensure proper ZGA. On the contrary, HDACs revert broad H3K27ac domains to canonical domains and safeguard ZGA by preventing premature expression of developmental genes. In conclusion, coordinated activities of CBP/p300 and HDACs during mouse MZT are essential for ZGA and preimplantation development.

HDAC1 in the Ovarian Granulosa Cells of Tan Sheep Improves Cumulus Cell Expansion and Oocyte Maturation Independently of the EGF-like Growth Factors. BIOLOGY 2022; 11:biology11101464.

Abstract
Previous studies have shown that some of the histone deacetylases (HDACs) play diverse roles in the regulation of ovarian somatic cell development, oocyte maturation and early embryonic development in different species including sheep. This study aimed to clarify whether HDAC1 also played pivotal roles in regulating oocyte maturation in Tan sheep. The results showed that HDAC1 was expressed in the nuclei of both the granulosa cells and oocytes of the growing follicles in the Tan sheep's ovaries. However, the level of HDAC1 was unaffected by luteinizing hormone (LH) induction in cultured granulosa cells. Meanwhile, the specific inhibition of HDAC1 using pyroxamide did not induce significant changes in the expression levels of EGF-like growth factors in vitro, whereas both the cumulus expansion and oocyte maturation of the cultured cumulus oocyte complexes (COCs) were significantly inhibited by pyroxamide. Additionally, the numbers of histone acetylation sites (H4K5, H4K12, H3K14 and H3K9) in ovarian granulosa cells were significantly increased. In conclusion, a constant expression of HDAC1 in the growing follicles of Tan sheep may be pivotal for supporting oocyte growth and maturation, although its action may not be closely correlated with LH induction, nor does it directly affect the expression of the EGF-like factors. Our study implies that there may exist diverse functions of the respective HDACs in modulating female reproduction in sheep.

Abstract
Packaging of eukaryotic genome into chromatin is a major obstacle to cells encountering DNA damage caused by external or internal agents. For maintaining genomic integrity, the double-strand breaks (DSB) must be efficiently repaired, as these are the most deleterious type of DNA damage. The DNA breaks have to be detected in chromatin context, the DNA damage response (DDR) pathways have to be activated to repair breaks either by non‐ homologous end joining and homologous recombination repair. It is becoming clearer now that chromatin is not a mere hindrance to DDR, it plays active role in sensing, detection and repair of DNA damage. The repair of DSB is governed by the reorganization of the pre-existing chromatin, leading to recruitment of specific machineries, chromatin remodelling complexes, histone modifiers to bring about dynamic alterations in histone composition, nucleosome positioning, histone modifications. In response to DNA break, modulation of chromatin occurs via various mechanisms including post-translational modification of histones. DNA breaks induce many types of histone modifications, such as phosphorylation, acetylation, methylation and ubiquitylation on specific histone residues which are signal and context dependent. DNA break induced histone modifications have been reported to function in sensing the breaks, activating processing of breaks by specific pathways, and repairing damaged DNA to ensure integrity of the genome. Favourable environment for DSB repair is created by generating open and relaxed chromatin structure. Histone acetylation mediate de-condensation of chromatin and recruitment of DSB repair proteins to their site of action at the DSB to facilitate repair. In this review, we will discuss the current understanding on the critical role of histone acetylation in inducing changes both in chromatin organization and promoting recruitment of DSB repair proteins to sites of DNA damage. It consists of an overview of function and regulation of the deacetylase enzymes which remove these marks and the function of histone acetylation and regulators of acetylation in genome surveillance.

Abstract
The genome is transcriptionally inert at fertilization and must be activated through a remarkable developmental process called zygotic genome activation (ZGA). Epigenetic reprogramming contributes significantly to the dynamic gene expression during ZGA; however, the mechanism has yet to be resolved. Here, we find histone deacetylases 1 and 2 (HDAC1/2) can regulate ZGA through lysine deacetylase activity. Notably, in mouse embryos, overexpression of a HDAC1/2 dominant-negative mutant leads to developmental arrest at the two-cell stage. RNA-seq reveals that 64% of downregulated genes are ZGA genes and 49% of upregulated genes are developmental genes. Inhibition of the deacetylase activity of HDAC1/2 causes a failure of histone deacetylation at multiple sites, including H4K5, H4K16, H3K14, H3K18 and H3K27. ChIP-seq analysis exhibits an increase and decrease of H3K27ac enrichment at promoters of up- and downregulated genes, respectively. Moreover, HDAC1 mutants prohibit the removal of H3K4me3 by impeding expression of Kdm5 genes. Importantly, the developmental block can be greatly rescued by Kdm5b injection and by partially correcting the expression of the majority of dysregulated genes. Similar functional significance of HDAC1/2 is conserved in bovine embryos. Overall, we propose that HDAC1/2 are indispensable for ZGA by creating correct transcriptional repressive and active states in mouse and bovine embryos.

The vulnerable primed cancer stem cells in disguise: demystifying the role of Maspin. Cancer Metastasis Rev 2022; 41:965-974.

Abstract
Epithelial-specific Maspin is widely known as a tumor suppressor. However, while the level of maspin expression is inversely correlated with tumor grade and stage, emerging clinical evidence shows a correlation between seemingly better differentiated tumor cells that express Maspin in both the nucleus and the cytoplasm, (n + c)Maspin, with a poor prognosis of many types of cancer. Biological studies demonstrate that Maspin plays an essential role in stem cell differentiation. In light of the recently established characterization of primed stem cells (P-SCs) in development, we propose, for the first time, that cancer stem cells (CSCs) also need to undergo priming (P-CSCs) before their transition to various progeny phenotypes. We envisage major differences in the steady state kinetics between P-SCs and P-CSCs. We further propose that P-CSCs of carcinoma are both marked and regulated by (n + c)Maspin. The concept of P-CSCs helps explain the apparent dichotomous relationships of (n + c)Maspin expression with cancer diagnosis and prognosis, and is supported by the evidence from mechanistic studies. We believe that the potential utility of (n + c)Maspin as a molecular marker of P-CSCs may significantly accelerate the advancement in our understanding of the genesis of tumor phenotypic plasticity in response to changes of tumor microenvironments (TME) or drug treatments. The vulnerabilities of the cellular state of (n + c)Maspin-expressing P-CSCs are also discussed as the rationale for future development of P-CSC-targeted chemotherapeutic and immunotherapeutic strategies.

Abstract
Epigenetic marks, such as DNA methylation and posttranslational modifications of core histones, are the key regulators of gene expression. In the mouse, many of these marks are erased during gamete formation and must be introduced de novo after fertilization. Some of them appear synchronously, but the others are deposited asynchronously and/or remain differently distributed on maternal and paternal chromatin. Although the mechanisms regulating these processes are not entirely understandable, it is commonly accepted that epigenetic reprogramming occurring during the first cell cycle of a mouse embryo is crucial for its further development. This chapter focuses on selected epigenetic modifications, such as DNA methylation, the introduction of histone variants, histones acetylation, phosphorylation, and methylation. Properly depositing these marks on maternal and paternal chromatin is crucial for normal embryonic development.

Abstract
With the intent to achieve the best modalities for myocardial cell therapy, different cell types are being evaluated as potent sources for differentiation into cardiomyocytes. Embryonic stem cells and induced pluripotent stem cells have great potential for future progress in the treatment of myocardial diseases. We reviewed aspects of epigenetic mechanisms that play a role in the differentiation of these cells into cardiomyocytes. Cardiomyocytes proliferate during fetal life, and after birth, they undergo permanent terminal differentiation. Upregulation of cardiac-specific genes in adults induces hypertrophy due to terminal differentiation. The repression or expression of these genes is controlled by chromatin structural and epigenetic changes. However, few studies have reviewed and analyzed the epigenetic aspects of the differentiation of embryonic stem cells and induced pluripotent stem cells into cardiac lineage cells. In this review, we focus on the current knowledge of epigenetic regulation of cardiomyocyte proliferation and differentiation from embryonic and induced pluripotent stem cells through histone modification and microRNAs, the maintenance of pluripotency, and its alteration during cardiac lineage differentiation.

Abstract
Cadmium is an environmental pollutant that has extensive deleterious effects on the reproductive system. However, the mechanisms underlying the effects of cadmium on preimplantation embryos are unclear. Here, we used a mouse model to investigate the effects of maternal cadmium (32 mg/l) exposure in drinking water for 2 days on early embryonic development, and studied the mechanisms associated with epigenetic modifications and DNA damage induced by oxidative stress. We observed that maternal cadmium exposure impaired preimplantation embryo development by inducing embryo death, fragmentation, or developmental blockade. After cadmium exposure, the most survived embryos were at the 8-cell stage, which were used for all measurements. Histone acetylation, not methylation, was disturbed by increasing histone deacetylase 1 (HDAC1) levels after cadmium exposure. Cadmium also disrupted DNA methylation of H19; however genomic DNA methylation can be normally reprogrammed in embryos. Furthermore, cadmium increased reactive oxygen species (ROS) levels and DNA damage, and partly inhibited gene expression related to DNA repair. The distribution and activity of mitochondria was increased; therefore, embryos maintain intracellular homeostasis for survival. Collectively, our findings revealed that maternal cadmium exposure impairs preimplantation embryo development by disturbing the epigenetic modification and inducing DNA damage.

Abstract
In mammalian cloning by somatic cell nuclear transfer (SCNT), the treatment of reconstructed embryos with histone deacetylase (HDAC) inhibitors improves efficiency. So far, most of those used for SCNT are hydroxamic acid derivatives-such as trichostatin A-characterized by their broad inhibitory spectrum. Here, we examined whether mouse SCNT efficiency could be improved using chlamydocin analogues, a family of newly designed agents that specifically inhibit class I and IIa HDACs. Development of SCNT-derived embryos in vitro and in vivo revealed that four out of five chlamydocin analogues tested could promote the development of cloned embryos. The highest pup rates (7.1-7.2%) were obtained with Ky-9, similar to those achieved with trichostatin A (7.2-7.3%). Thus, inhibition of class I and/or IIa HDACs in SCNT-derived embryos is enough for significant improvements in full-term development. In mouse SCNT, the exposure of reconstructed oocytes to HDAC inhibitors is limited to 8-10 h because longer inhibition with class I inhibitors causes a two-cell developmental block. Therefore, we used Ky-29, with higher selectivity for class IIa than class I HDACs for longer treatment of SCNT-derived embryos. As expected, 24-h treatment with Ky-29 up to the two-cell stage did not induce a developmental block, but the pup rate was not improved. This suggests that the one-cell stage is a critical period for improving SCNT cloning using HDAC inhibitors. Thus, chlamydocin analogues appear promising for understanding and improving the epigenetic status of mammalian SCNT-derived embryos through their specific inhibitory effects on HDACs.

Abstract
STUDY QUESTION Are there any differences between in vivo (IVV) and in vitro (IVT) matured metaphase II (MII) oocytes at the molecular level? SUMMARY ANSWER Between IVV and IVT oocytes, 507 differentially expressed genes (DEGs) were identified; the non-CpG methylomes were significantly different, but the CpG methylomes and genomic copy number variations (CNVs) were similar. WHAT IS KNOWN ALREADY A previous study using microarray and single-cell RNA-seq analysis revealed that numerous genes were differentially expressed between IVV and IVT oocytes. Independent studies of DNA methylation profiling in human oocytes have revealed negative correlations between gene transcription and the DNA methylation level at gene promoter regions. No study has compared global CpG or non-CpG methylation between these two groups of oocytes. Although a high level of aneuploidy has been reported in MII oocytes, no direct comparison of IVV and IVT oocytes based on single-cell sequencing data has been performed. STUDY DESIGN, SIZE, DURATION We collected eight IVV oocytes from six patients and seven IVT oocytes from seven patients and then analysed each oocyte using the previously established single-cell triple omics sequencing (scTrioseq) analysis to determine associations among the transcriptome, DNA methylome and chromosome ploidy in the oocytes. PARTICIPANTS/MATERIALS, SETTING, METHODS All IVV oocytes were donated by patients who received 150 IU gonadotropin per day from the third day of their menstrual cycle, followed by GnRH antagonist after 5 days of gonadotropin stimulation. All IVT oocytes were from immature oocytes which were donated by volunteers undergoing delivery by caesarean section then cultured in oocyte maturation medium containing 75 mIU/ml hMG for 24 to 48 h. Every single oocyte was analysed using the previously established single-cell multiomic sequencing analysis. MAIN RESULTS AND THE ROLE OF CHANCE There were 507 genes differentially expressed between the IVV (n = 8) and IVT (n = 7) oocytes, even though their global transcriptome profiles were similar. The enriched genes in IVV oocytes were related to the cell cycle process while those in IVT oocytes were related to mitochondrial respiration biogenesis. Although the global CpG methylation of the two groups of oocytes was similar, the non-CpG methylation level in IVV oocytes was higher than that in IVT oocytes. A high aneuploidy ratio was found in both groups, but the aneuploidy did not affect transcription according to the correlation analysis. LARGE-SCALE DATA N/A. LIMITATIONS AND REASONS FOR CAUTION Due to the difficulty in collecting MII oocytes, especially IVV matured oocytes, the sample size was limited. WIDER IMPLICATIONS OF THE FINDINGS Our findings indicate that single-cell multiomic sequencing can be utilised to examine the similarity and differences between IVV and IVT matured MII oocytes. STUDY FUNDING/COMPETING INTEREST(S) This work was supported by the Ministry of Science and Technology of China, National Key R&D Program of China (No. 2017YFC1001601). The donated oocytes were collected by Shanghai Tenth People's Hospital. The authors declare no competing interests.

Abstract
Meiosis is the basis of sexual reproduction. In female mammals, meiosis of oocytes starts before birth and sustains at the dictyate stage of meiotic prophase I before gonadotropins-induced ovulation happens. Once meiosis gets started, the oocytes undergo the leptotene, zygotene, and pachytene stages, and then arrest at the dictyate stage. During each estrus cycle in mammals, or menstrual cycle in humans, a small portion of oocytes within preovulatory follicles may resume meiosis. It is crucial for females to supply high quality mature oocytes for sustaining fertility, which is generally achieved by fine-tuning oocyte meiotic arrest and resumption progression. Anything that disturbs the process may result in failure of oogenesis and seriously affect both the fertility and the health of females. Therefore, uncovering the regulatory network of oocyte meiosis progression illuminates not only how the foundations of mammalian reproduction are laid, but how mis-regulation of these steps result in infertility. In order to provide an overview of the recently uncovered cellular and molecular mechanism during oocyte maturation, especially epigenetic modification, the progress of the regulatory network of oocyte meiosis progression including meiosis arrest and meiosis resumption induced by gonadotropins is summarized. Then, advances in the epigenetic aspects, such as histone acetylation, phosphorylation, methylation, glycosylation, ubiquitination, and SUMOylation related to the quality of oocyte maturation are reviewed.

Maternal UHRF1 Is Essential for Transcription Landscapes and Repression of Repetitive Elements During the Maternal-to-Zygotic Transition. Front Cell Dev Biol 2021; 8:610773. [PMID: 33634103 PMCID: PMC7902027 DOI: 10.3389/fcell.2020.610773] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Accepted: 12/31/2020] [Indexed: 11/21/2022] Open
Abstract
Maternal factors that modulate maternal-to-zygotic transition (MZT) are essential for the growth from specialized oocytes to totipotent embryos. Despite several studies, the mechanisms regulating epigenetic reprogramming during MZT remain largely elusive. UHRF1 plays a role in maintaining GC methylation in oocytes and early embryos. However, little is known about its role in mouse MZT. Here, we explored the function of maternal UHRF1 in zygotic genome regulation during early embryonic development in mice. We showed that the conditional knockout (cKO) of UHRF1 in either primordial or growing oocytes causes infertility but differentially affects early embryonic development. UHRF1 deficiency in primordial oocytes led to early embryonic developmental arrest at the two-cell stage, accompanied by significant alterations in global DNA and H3K4me3 methylation patterns. In comparison, UHRF1 ablation in growing oocytes significantly reduced developmental competence from two-cell embryos to blastocysts. At the transcriptional level, the absence of maternal UHRF1 led to aberrant transcriptional regulation of the zygotic genome during MZT at the two-cell stage. Furthermore, we observed that retrotransposable elements in UHRF1-deficient oocytes and embryos were not silenced properly; in particular, the LINE-1 and long terminal repeat (LTR) subfamily were activated abnormally. Collectively, the findings of our study reveal that maternal UHRF1 plays a critical role in establishing the correct epigenetic chromatin reprogramming of early embryos, regulating essential genes during MZT, and preserving genome integrity that drives early embryonic development in mice.

Abstract
The molecular mechanisms of drug use on sexual health are largely unknown. We investigated, the relationship between heroin use disorder and epigenetic factors influencing histone acetylation in sperm cells. The volunteers included twenty-four 20- to 50-year-old men with a normal spermogram who did not consume any drugs and twenty-four age- to BMI-matched men who consume only the drug heroin for more than last four months. HDAC1 and HDAC11 mRNA expression levels in spermatozoa and miR-34c-5p and miR-125b-5p expression levels in seminal plasma were measured. The heroin-user group showed significantly increased white blood cell counts and decreased sperm motility and survival rates (8.61 ± 1.73, 21.50 ± 3.11, 69.90 ± 4.69 respectively) as compared to the control group (1.49 ± 0.32, 38.82 ± 3.05, 87.50 ± 0.99 respectively) (p ≤ .001). An increase in DNA fragmentation index (DFI) (heroin-user group: 41.93 ± 6.59% and control group: 10.14 ± 1.43%, p = .003), a change in frequency of HDAC1 (heroin-user group: 1.69 ± 0.55 and control group: 0.45 ± 0.14, p = .045) and HDAC11 (heroin-user group: 0.29 ± 0.13 and control group: 2.36 ± 0.76, p = .019) in spermatozoa and a significant decrease in seminal miR-125b-5p abundance (heroin-user group: 0.37 ± 0.11 and control group: 1.59 ± 0.47, p = .028) were reported in heroin consumers. Heroin use can lead to male infertility by causing leukocytospermia, asthenozoospermia, DFI elevation in sperm cells and alterations in seminal RNA profile.

Abstract
Cardiovascular diseases are the leading cause of mortality and morbidity worldwide. Histone deacetylases (HDACs) play an important role in the epigenetic regulation of genetic transcription in response to stress or pathological conditions. HDACs interact with a complex co-regulatory network of transcriptional regulators, deacetylate histones or non-histone proteins, and modulate gene expression in the heart. The selective HDAC inhibitors have been considered to be a critical target for the treatment of cardiac disease, especially for ameliorating cardiac dysfunction. In this review, we discuss our current knowledge of the cellular and molecular basis of HDACs in mediating cardiac development and hypertrophy and related pharmacologic interventions in heart disease.

Abstract
Mitochondria, originally of bacterial origin, are highly dynamic organelles that have evolved a symbiotic relationship within eukaryotic cells. Mitochondria undergo dynamic, stage-specific restructuring and redistribution during oocyte maturation and preimplantation embryo development, necessary to support key developmental events. Mitochondria also fulfil a wide range of functions beyond ATP synthesis, including the production of intracellular reactive oxygen species and calcium regulation, and are active participants in the regulation of signal transduction pathways. Communication between not only mitochondria and the nucleus, but also with other organelles, is emerging as a critical function which regulates preimplantation development. Significantly, perturbations and deficits in mitochondrial function manifest not only as reduced quality and/or poor oocyte and embryo development but contribute to post-implantation failure, long-term cell function and adult disease. A growing body of evidence indicates that altered availability of metabolic co-factors modulate the activity of epigenetic modifiers, such that oocyte and embryo mitochondrial activity and dynamics have the capacity to establish long-lasting alterations to the epigenetic landscape. It is proposed that preimplantation embryo development may represent a sensitive window during which epigenetic regulation by mitochondria is likely to have significant short- and long-term effects on embryo, and offspring, health. Hence, mitochondrial integrity, communication and metabolism are critical links between the environment, the epigenome and the regulation of embryo development.

Abstract
The importance of germline-inherited post-translational histone modifications on priming early mammalian development is just emerging1-4. Histone H3 lysine 9 (H3K9) trimethylation is associated with heterochromatin and gene repression during cell-fate change5, whereas histone H3 lysine 4 (H3K4) trimethylation marks active gene promoters6. Mature oocytes are transcriptionally quiescent and possess remarkably broad domains of H3K4me3 (bdH3K4me3)1,2. It is unknown which factors contribute to the maintenance of the bdH3K4me3 landscape. Lysine-specific demethylase 4A (KDM4A) demethylates H3K9me3 at promoters marked by H3K4me3 in actively transcribing somatic cells7. Here, we report that KDM4A-mediated H3K9me3 demethylation at bdH3K4me3 in oocytes is crucial for normal pre-implantation development and zygotic genome activation after fertilization. The loss of KDM4A in oocytes causes aberrant H3K9me3 spreading over bdH3K4me3, resulting in insufficient transcriptional activation of genes, endogenous retroviral elements and chimeric transcripts initiated from long terminal repeats during zygotic genome activation. The catalytic activity of KDM4A is essential for normal epigenetic reprogramming and pre-implantation development. Hence, KDM4A plays a crucial role in preserving the maternal epigenome integrity required for proper zygotic genome activation and transfer of developmental control to the embryo.

Abstract
Objective Regarding that undifferentiated mesenchymal stem cells, as donor cells, require less epigenetic
reprogramming, possibility of using bovine adipose tissue-derived stem cells (BASCs) with low level of DNMTs and
HDACs expression was evaluated.
Materials and Methods In this experimental study, we examined gene expression of epigenetic modifiers including
DNA methyltransferases (DNMT1, DNMT3A and DNMT3B) and histone deacetylases (HDAC1-3), as well as protein
levels of histone H3 acetylation at lysine 9 (H3K9ac) and POU5F1 (also known as OCT4) at two stages of preimplantation
development among in vitro fertilization (IVF), parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT)
groups.
Results The results revealed that developmental competence of IVF embryos was higher than SCNT embryos
(P<0.05). In the PA and SCNT groups, DNMT1, HDAC2 and HDAC3 mRNA were overexpressed (P<0.05), and proteins
levels of H3K9ac and POU5F1 were reduced at 6-8 cells and blastocyst stages compared to IVF (P<0.05). The mRNA
expression of DNMT1 an<0.05) in both developmental stages (except HDAC1 in blastocyst stage).
Conclusion The SCNT embryos derived from BASCs have endured considerable nuclear reprogramming during early
embryo development. Comparison of PA and SCNT blastocysts demonstrated that HDAC1 and DNMT1 may attribute to
developmental competence variability of bovine embryos.

Abstract
Epigenetic modifications, including DNA methylation and histone modifications, are reprogrammed considerably following fertilization during mammalian early embryonic development. Incomplete epigenetic reprogramming is a major factor leading to poor developmental outcome in embryos generated by assisted reproductive technologies, such as somatic cell nuclear transfer. However, the role of histone modifications in preimplantation development is poorly understood. Here, we show that co-knockdown (cKD) of Hdac1 and 2 (but not individually) resulted in developmental failure during the morula to blastocyst transition. This outcome was also confirmed with the use of small-molecule HDAC1/2-specific inhibitor FK228. We observed reduced cell proliferation and increased incidence of apoptosis in cKD embryos, which were likely caused by increased acetylation of TRP53. Importantly, both RNA-seq and immunostaining analysis revealed a failure of lineage specification to generate trophectoderm and pluripotent cells. Among many gene expression changes, a substantial decrease of Cdx2 may be partly accounted for by the aberrant Hippo pathway occurring in cKD embryos. In addition, we observed an increase in global DNA methylation, consistent with increased DNA methyltransferases and UHRF1. Interestingly, deficiency of RBBP4 and 7 (both are core components of several HDAC1/2-containing epigenetic complexes) results in similar phenotypes as those of cKD embryos. Overall, HDAC1 and 2 play redundant functions required for lineage specification, cell viability and accurate global DNA methylation, each contributing to critical developmental programmes safeguarding a successful preimplantation development.

Abstract
Suppressor interacting 3a (Sin3a) is a scaffold component of the chromatin repressive complex Sin3/histone deacetylase (Hdac). Sin3a has been shown as a hub gene driving preimplantation development in both mice and humans. However, its precise functions during preimplantation development remain unclear. Here, we show that the embryos arrested at morula stage upon specific depletion of Sin3a in mouse early embryos. Given the reduced cell number in Sin3a-depleted embryos, blocked cell proliferation is observed, likely because of the increased level of Trp53 acetylation at lysine 379. Moreover, we found that Sin3a depletion reduces Cdx2 and Tir Na Nog (Nanog), suggesting a failure of the first cell fate decision. In addition, we noted a striking increase of genome-wide DNA methylation, likely attributed to the increased nuclear DNA methyltransferase 1 observed in Sin3a-depleted embryos. Notably, RNA sequencing analyses showed 717 genes are differentially expressed, and Gene Ontology analysis of down-regulated genes (e.g., Hdac1) revealed top enriched terms involving protein deacetylation. Consistently, we confirmed a significant decrease of Hdac1 mRNA and protein abundance. Importantly, the development and Trp53 acetylation in Sin3a-depleted embryos could be rescued by expression of Hdac1 but not Hdac2. In summary, our results indicate a vital role of Sin3a in safeguarding the developmental progression through the morula-to-blastocyst transition via Hdac1.-Zhao, P., Li, S., Wang, H., Dang, Y., Wang, L., Liu, T., Wang, S., Li, X., Zhang, K. Sin3a regulates the developmental progression through morula-to-blastocyst transition via Hdac1.

Abstract
Histone acetylation is one of the most important posttranslational modifications that contribute to transcriptional initiation and chromatin remodeling. In the present study, we aimed to investigate the effect of sodium butyrate (NaBu), a natural histone deacetylase inhibitor (HDACi), on the maturation of oocytes, preimplantation embryonic development, and expression of important developmental genes. The results indicated that NaBu decreased the rates of GVBD and the first polar body extrusion (PBE) in vitro in a dose-dependent manner. Meanwhile, NaBu treatment led to an abnormality in the spindle apparatus in oocytes in MI. However, the ratio of phosphor-extracellular signal-regulated kinases (p-ERK)/ERK significantly decreased in oocytes treated with 2.0 mM NaBu for 8 h. Furthermore, NaBu treatment at 2.0 mM improved the quality of embryos and the mRNA expression levels of important developmental genes such as HDAC1, Sox2, and Pou5f1. These data suggest that although a high concentration NaBu will impede the meiosis of oocytes, 2.0 mM NaBu will promote the development of embryos in vitro. Further investigation is needed to clarify the direct/indirect effects of NaBu on the regulation of important developmental genes and their subsequent impacts on full-term development in mammals.

Abstract
Understanding factors that regulate zygotic genome activation (ZGA) is critical for determining how cells are reprogrammed to become totipotent or pluripotent. There is limited information regarding how this process occurs physiologically in early mammalian embryos. Here, we identify a mediator complex subunit, MED13, as translated during mouse oocyte maturation and transcribed early from the zygotic genome. Knockdown and conditional knockout approaches demonstrate that MED13 is essential for ZGA in the mouse, in part by regulating expression of the embryo-specific chromatin remodeling complex, esBAF. The role of MED13 in ZGA is mediated in part by interactions with E2F transcription factors. In addition to MED13, its paralog, MED13L, is required for successful preimplantation embryo development. MED13L partially compensates for loss of MED13 function in preimplantation knockout embryos, but postimplantation development is not rescued by MED13L. Our data demonstrate an essential role for MED13 in supporting chromatin reprogramming and directed transcription of essential genes during ZGA.

Abstract
An increasing number of studies have revealed that histone deacetylase (HDAC) mediated histone deacetylation is important for mammalian oocyte development. However, nonselective HDAC inhibitors (HDACi) were applied in most studies; the precise functions of specific HDAC classes during meiosis are poorly defined. In this study, the class IIa-specific HDACi MC1568 was used to reveal a crucial role of class IIa HDACs in the regulation of histone deacetylation during porcine oocyte meiosis. Besides, the functions of HDACs and histone acetyltransferases in regulating the balance of histone acetylation/deacetylation were also confirmed during oocyte maturation. After the validation of nontoxicity of MC1568 in maturation rate, spindle morphology, and chromosome alignment, effects of MC1568 on developmental competence of porcine somatic cell nuclear transfer (SCNT) embryos were evaluated, and data indicated that treatment with 10 μM MC1568 for 12 hours following electrical activation significantly enhanced the blastocyst rate and cell numbers. Moreover, results showed that optimal MC1568 treatment increased the H4K12 acetylation level in SCNT one cells and two cells. In addition, MC1568 treatment stimulated expression of the development-related genes OCT4, CDX2, SOX2, and NANOG in SCNT blastocysts. Collectively, our investigation uncovered a critical role of class IIa HDACs in the regulation of histone deacetylation during oocyte meiosis. Furthermore, for the first time, we showed that MC1568 can improve the in vitro development of porcine SCNT embryos. These findings provide an alternative HDACi for improving animal cloning efficiency and may shed more light on nuclear reprogramming.

Abstract
Recently, the modification of the epigenetic status of somatic cell nuclear transfer (SCNT) embryos by treatment with histone deacetylase inhibitors (HDACis) has made it possible to alter
epigenetic traits and improve the developmental competence of these embryos. In the current study, we examined the effects of an HDACi, quisinostat (JNJ), on the in vitro
development of porcine cloned embryos and their epigenetic nuclear reprogramming status. SCNT embryos were cultured under various conditions, and we found that treatment with 100 nM JNJ for
24 h post activation could improve blastocyst formation rates compared to the control (P < 0.05). Therefore, this was chosen as the optimal condition and used for further investigations.
To explore the effects of JNJ on the nuclear reprogramming of early stage embryos and how it improved cloning efficiency, immunofluorescence staining and quantitative real-time PCR were
performed. From the pseudo-pronuclear to 2-cell stages, the levels of acetylation of histone 3 at lysine 9 (AcH3K9) and acetylation of histone 4 at lysine 12 (AcH4K12) increased, and global
DNA methylation levels revealed by anti-5-methylcytosine (5-mC) antibody staining were decreased in the JNJ-treated group compared to the control (P < 0.05). However, JNJ treatment failed
to alter AcH3K9, AcH4K12, or 5-mC levels at the 4-cell embryo stage. Moreover, JNJ treatment significantly upregulated the expression of the development-related genes OCT4,
SOX2, and NANOG, and reduced the expression of genes related to DNA methylation (DNMT1, DNMT3a, and
DNMT3b) and histone acetylation (HDAC1, HDAC2, and HDAC3). Together, these results suggest that treatment of SCNT
embryos with JNJ could promote their developmental competence by altering epigenetic nuclear reprogramming events.

Abstract
Histone deacetylases (HDACs) have been implicated in numerous biological events. However, to date, the role of HDAC6 in early embryos remains unknown. In the current study, Tubastatin A (TubA), a potent HDAC6 inhibitor, was used to block HDAC6 activity in mouse embryos. We found that TubA exposure significantly reduced the blastocyst formation of early embryos. Confocal microscopy revealed the markedly increased chromosomal congression failure in the mouse embryos treated with the HDAC6 inhibitor. Moreover, the HDAC6 inhibition resulted in the overproduction of reactive oxygen species (ROS) in embryos. In addition, we observed the accumulation of phosphorylated γH2AX in TubA-treated embryos, indicative of the increased DNA damage. In line with this, cell apoptosis of blastocysts was frequently detected in HDAC6-deficient embryos compared with their controls. Altogether, our data indicate that HDAC6 may serve as an important regulator of chromatin structure and mitochondrial function, determining the developmental potential of the early embryos of mouse.

Abstract
BACKGROUND Histone deacetylase (HDAC) influences the acetylation status of histones at gene promotor loci, providing an epigenetic mechanism that regulates gene expression. METHODS We determined if variations in the composition of the vaginal microbiome in pregnant women were associated with alterations in the level of HDAC1 in vaginal epithelial cells and whether this influenced the concentration of compounds present in vaginal fluid. Vaginal epithelial cells were obtained from 150 women in their first trimester of pregnancy, lysed and assayed for HDAC1 by ELISA. Composition of the vaginal microbiome was determined by classification of sequences amplified from the V1-V3 region of bacterial ribosomal 16S rRNA genes. Vaginal secretions were assayed for total protein, matrix metalloproteinase (MMP)-8, the 70kDa heat shock protein (hsp70) and the D- and L-lactic acid isomers. RESULTS Lactobacilli were numerically dominant in 119 (79.3%) of the women, with Lactobacillus crispatus being the most prevalent (45.3% of women). Gardnerella was the most prevalent non-Lactobacillus species (10.7% of women). The median HDAC1 level in epithelial cells was 6.1 ng/mL when lactobacilli predominated vs. 20.5 ng/mL when non-lactobacilli were dominant (P=0.0039). Levels were lowest when L. crispatus was dominant (3.8 ng/mL) and highest with Streptococcus dominance (38.1 ng/mL). The concentration of HDAC1 was negatively correlated with the D-lactic acid level (P=0.0183) and positively correlated with concentrations of MMP-8 and hsp70 (P<0.0001) in the vaginal fluid. CONCLUSIONS We propose that the composition of the vaginal microbiome and level of D-lactic acid, by influencing the HDAC1 level in vaginal epithelial cells, may epigenetically contribute to variations in the concentration of compounds in vaginal fluid.

Anacardic Acid Reduces Acetylation of H4K12 in Mouse Oocytes during Vitrification. CELL JOURNAL 2018; 20:552-558. [PMID: 30124002 PMCID: PMC6099150 DOI: 10.22074/cellj.2019.5601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Accepted: 02/06/2018] [Indexed: 11/10/2022]
Abstract
Objective Over the last years, vitrification has been widely used for oocyte cryopreservation, in animals and humans; however,
it frequently causes minor and major epigenetic modifications. The effect of oocyte vitrification on levels of acetylation of
histone H4 at lysine 12 (AcH4K12), and histone acetyltransferase (Hat) expression, was previously assessed; however, little is
known about the inhibition of Hat expression during oocyte vitrification. This study evaluated the effect of anacardic acid (AA)
as a Hat inhibitor on vitrified mouse oocytes.
Materials and Methods In this experimental study, 248 mouse oocytes at metaphase II (MII) stage were divided in three
experimental groups namely, fresh control oocytes (which were not affected by vitrification), frozen/thawed oocytes (vitrified)
and frozen/thawed oocytes pre-treated with AA (treatment). Out of 248 oocytes, 173 oocytes were selected and from them,
84 oocytes were vitrified without AA (vitrified group) and 89 oocytes were pretreated with AA, and then vitrified (treatment
group). Fresh MII mouse oocytes were used as control group. Hat expression and AcH4K12 levels were assessed by using
real-time quantitative polymerase chain reaction (PCR) and immunofluoresce staining, respectively. In addition, survival rate
was determined in vitrified and treatment oocytes.
Results Hat expression and AcH4K12 modification significantly increased [4.17 ± 1.27 (P≤0.001) and 97.57 ± 6.30
(P<0.001), respectively] in oocytes that were vitrified, compared to the fresh oocytes. After treatment with AA, the Hat
mRNA expression and subsequently H4K12 acetylation levels were significantly reduced [0.12 ± 0.03 (P≤0.001) and
89.79 ± 3.20 (P≤0.05), respectively] in comparison to the vitrified group. However, the survival rate was not significantly
different between the vitrified (90.47%) and treatment (91.01%) groups (P>0.05).
Conclusion The present study suggests that AA reduces vitrification risks caused by epigenetic modifications, but does not
affect the quality of vitrification. In fact, AA as a Hat inhibitor was effective in reducing the acetylation levels of H4K12.

Abstract
BACKGROUND Maternal diabetes related neural tube defects (NTDs) are a result of oxidative stress and apoptosis. However, the molecular mechanism behind the pathogenesis is not fully understood. Here, we report that high glucose exposure-induced epigenetic changes influence histone H4 acetylation and neuroepithelial cell proliferation. We also show that the acetyltransferase inhibitor C646 can prevent high glucose induced changes in histone H4 acetylation and neuroepithelial cell proliferation. METHODS By using LC-MS/MS as an unbiased approach, we screened the histone acetylation profile in an E9 neuroepithelial cell line (NE-4C) under high glucose exposure. We further explored the mechanism in cells in vitro and in maternal diabetes-induced mouse embryos in vivo. RESULTS We identified 35 core histone acetylation marks in normal E9 neuroepithelial cells, whereas high glucose exposure resulted in novel acetylation sites on H4K31 and H4K44. Acetylation levels of embryonic development associated H4K5/K8/K12/K16 increased in neuroepithelial cells exposed to high glucose in vitro and in brain tissue from maternal diabetes induced exencephalic embryos in vivo. Further, mRNA level of histone acetyltransferase CBP encoded gene Crebbp was significantly increased both in vitro and in vivo. The addition of C646, a selective inhibitor for CBP/p300, significantly rescued increase of H4K5/K8/K12/K16 acetylation levels and H3S10pi-labeled neuroepithelial cell proliferation induced by high glucose exposure. CONCLUSION Our data provide complementary insights for potential mechanisms of maternal diabetes induced NTDs.

Abstract
Implantation failure and genetic developmental disabilities in mammals are caused by errors in chromosome segregation originating mainly in the oocyte during meiosis I. Some conditions, like maternal ageing or in vitro maturation (IVM), increase the incidence of oocyte aneuploidy. Here oocytes from adult mares were used to investigate oocyte maturation in a monovulatory species. Experiments were conducted to compare: (1) the incidence of aneuploidy, (2) the morphology of the spindle, (3) the acetylation of lysine 16 on histone H4 (H4K16) and (4) the relative amount of histone acetyltransferase 1 (HAT1), K(lysine) acetyltransferase 8 (KAT8, also known as MYST1), histone deacetylase 1 (HDAC1) and NAD-dependent protein deacetylase sirtuin 1 (SIRT1) mRNA in metaphase II stage oocytes that were in vitro matured or collected from peri-ovulatory follicles. The frequency of aneuploidy and anomalies in spindle morphology was increased following IVM, along with a decrease in H4K16 acetylation that was in agreement with our previous observations. However, differences in the amount of the transcripts investigated were not detected. These results suggest that the degradation of transcripts encoding for histone deacetylases and acetyltransferases is not involved in the changes of H4K16 acetylation observed following IVM, while translational or post-translational mechanisms might have a role. Our study also suggests that epigenetic instabilities introduced by IVM may affect the oocyte and embryo genetic stability.

[PMID: 28878090 PMCID: PMC5592804 DOI: 10.1530/rep-17-0112] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2017] [Revised: 05/04/2017] [Accepted: 07/04/2017] [Indexed: 01/26/2023]
Abstract
Acetylation of histone proteins is a major determinant of chromatin structure and function. Fertilisation triggers a round of chromatin remodelling that prepares the genome for the first round of transcription from the new embryonic genome. In this study we confirm that fertilisation leads to a marked progressive increase in the level of histone 3 lysine 9 acetylation in both the paternally and maternally derived genomes. The culture of zygotes in simple defined media caused a marked increase in the global level of acetylation and this affected the male pronucleus more than the female. The culture created a marked asymmetry in staining between the two pronuclei that was not readily detected in zygotes collected directly from the reproductive tract and was ameliorated to some extent by optimized culture media. The increased acetylation caused by culture resulted in increased transcription of Hspa1b, a marker of embryonic genome activation. Pharmacological analyses showed the hyperacetylation of H3K9 and the increased expression of Hspa1b caused by culture were due to the altered net activity of a range of histone acetylases and deacetylases. The marked hyperacetylation of histone 3 lysine 9 caused by culture of zygotes may serve as an early biomarker for the effects of culture on the normal function of the embryo. The results also provide further evidence for an effect of the stresses associated with assisted reproductive technologies on the normal patterns of epigenetic reprogramming in the early embryo.

Abstract
Women are unique from all other mammals in that lactic acid is present at high levels in the vagina during their reproductive years. This dominance may have evolved in response to the unique human lifestyle and a need to optimally protect pregnant women and their fetuses from endogenous and exogenous insults. Lactic acid in the female genital tract inactivates potentially pathogenic bacteria and viruses, maximizes survival of vaginal epithelial cells, and inhibits inflammation that may be damaging to the developing fetus and maintenance of the pregnancy. In an analogous manner, lactic acid production facilitates survival of malignantly transformed cells, inhibits activation of immune cells, and prevents the release of pro-inflammatory mediators in response to tumor-specific antigens. Thus, the same stress-reducing properties of lactic acid that promote lower genital tract health facilitate malignant transformation and progression.

Abstract
This study examines the effects of the histone deacetylation inhibitor scriptaid (SCR) on preimplantation embryo development in vitro and on imprinting gene expression. We hypothesized that SCR would increase histone acetylation levels, enhance embryonic genome activation, and regulate imprinting and X-chromosome inactivation (XCI) in in vitro produced bovine embryos. Zygotes were cultured in vitro in presence or absence of SCR added at different time points. We assessed cleavage and blastocyst rates as well as the quality of blastocysts through: (i) differential cell counts; (ii) survival after vitrification/thawing and (iii) gene expression analysis -including imprinted genes. Blastocyst yields were not different in the control and experimental groups. While no significant differences were observed between groups in total cell or trophectoderm cell numbers, SCR treatment reduced the number of inner cell mass cells and improved the survival of vitrified embryos. Further, genes involved in the mechanism of paternal imprinting (GRB10, GNAS, XIST) were downregulated in presence of SCR compared with controls. These observations suggest SCR prevents deacetylation of paternally imprinting control regions and/or their up-regulation, as these events took place in controls. Whether or not such reductions in XIST and imprinting gene expression are beneficial for post implantation development remains to be clarified.

Abstract
Histone variant H3.3 is encoded by two distinct genes, H3F3A and H3F3B, that are closely associated with actively transcribed genes. H3.3 replacement is continuous and essential for maintaining correct chromatin structure during mouse oogenesis. Upon fertilization, H3.3 is incorporated to parental chromatin, and is required for blastocyst formation in mice. The H3.3 exchange process is facilitated by the chaperone HIRA, particularly during zygote development. We previously demonstrated that H3.3 is required for bovine early embryonic development; here, we explored the mechanisms of its functional requirement. H3F3A mRNA abundance is stable whereas H3F3B and HIRA mRNA are relatively dynamic during early embryonic development. H3F3B mRNA quantity is also considerably higher than H3F3A. Immunofluorescence analysis revealed an even distribution of H3.3 between paternal and maternal pronuclei in zygotes, and subsequent stage-specific localization of H3.3 in early bovine embryos. Knockdown of H3.3 by targeting both H3F3A and H3F3B dramatically decreased the expression of NANOG (a pluripotency marker) and CTGF (Connective tissue growth factor; a trophectoderm marker) in bovine blastocysts. Additionally, we noted that Histone H3 lysine 36 dimethylation and linker Histone H1 abundance is reduced in H3.3-deficient embryos, which was similar to effects following knockdown of CHD1 (Chromodomain helicase DNA-binding protein 1). By contrast, no difference was observed in the abundance of Histone H3 lysine 4 trimethylation, Histone H3 lysine 9 dimethylation, or Splicing factor 3 B1. Collectively, these results established that H3.3 is required for correct epigenetic modifications and H1 deposition, dysregulation of which likely mediate the poor development in H3.3-deficient embryos.

Abstract
Chromatin, the template for epigenetic regulation, is a highly dynamic entity that is constantly reshaped during early development and differentiation. Epigenetic modification of chromatin provides the necessary plasticity for cells to respond to environmental and positional cues, and enables the maintenance of acquired information without changing the DNA sequence. The mechanisms involve, among others, chemical modifications of chromatin, changes in chromatin constituents and reconfiguration of chromatin interactions and 3D structure. New advances in genome-wide technologies have paved the way towards an integrative view of epigenome dynamics during cell state transitions, and recent findings in embryonic stem cells highlight how the interplay between different epigenetic layers reshapes the transcriptional landscape.

Abstract
Epigenetics involves mechanisms independent of modifications in the DNA sequence that result in changes in gene expression and are maintained through cell divisions. Because all cells in the organism contain the same genetic blueprint, epigenetics allows for cells to assume different phenotypes and maintain them upon cell replication. As such, during the life cycle, there are moments in which the epigenetic information needs to be reset for the initiation of a new organism. In mammals, the resetting of epigenetic marks occurs at two different moments, which both happen to be during gestation, and include primordial germ cells (PGCs) and early preimplantation embryos. Because epigenetic information is reversible and sensitive to environmental changes, it is probably no coincidence that both these extensive periods of epigenetic remodelling happen in the female reproductive tract, under a finely controlled maternal environment. It is becoming evident that perturbations during the extensive epigenetic remodelling in PGCs and embryos can lead to permanent and inheritable changes to the epigenome that can result in long-term changes to the offspring derived from them, as indicated by the Developmental Origins of Health and Disease (DOHaD) hypothesis and recent demonstration of inter- and trans-generational epigenetic alterations. In this context, an understanding of the mechanisms of epigenetic remodelling during early embryo development is important to assess the potential for gametic epigenetic mutations to contribute to the offspring and for new epimutations to be established during embryo manipulations that could affect a large number of cells in the offspring. It is of particular interest to understand whether and how epigenetic information can be passed on from the gametes to the embryo or offspring, and whether abnormalities in this process could lead to transgenerationally inheritable phenotypes. The aim of this review is to highlight recent progress made in understanding the nature and mechanisms of epigenetic remodelling that ensue after fertilisation.

Abstract
Peptidylarginine deiminase (PADI) enzymes are increasingly being associated with the regulation of chromatin structure and gene activity via histone citrullination. As one of the PADI family members, PADI1 has been mainly reported to be expressed in the epidermis and uterus, where the protein in keratinocytes is thought to promote differentiation by citrullinating filament proteins. However, the roles of PADI1 in preimplantation development have not been addressed. Using a PADI1-specific inhibitor and Padi1-morpholino knockdown, we found that citrullination of histone tails at H4R3 and H3R2/8/17 were markedly reduced in the 2- and 4-cell embryos. Consistent with this observation, early embryo development was also arrested at the 4-cell stage upon depletion of PADI1 or inhibition of PADI1 enzyme activity. Additionally, by employing 5-ethynyl uridine (EU) incorporation analysis, ablation of PADI1 function led to a dramatic decrease in overall transcriptional activity, correlating well with the reduced levels of phosphorylation of RNA Pol II at Ser2 observed at 2- or 4-cell stage of embryos under Padi1 knockdown or inhibiting PADI1. Thus, our data reveal a novel function of PADI1 during early embryo development transitions by catalyzing histone tail citrullination, which facilitates early embryo genome transactivation.
