Abstract
BACKGROUND Neutrophils are a heterogeneous population capable of antimicrobial functions associated with pre-activation/activation and tissue regeneration. The specific polarisation of immune cells is mediated by the modification of 'chromatin landscapes', which enables differentiated access and activity of regulatory elements that guarantee their plasticity during inflammation No specific pattern within histone posttranslational modifications (PTMs) controlling this plasticity has been identified. METHODS Using the in vitro model of inflammation, reflecting different states of neutrophils from resting, pre-activated cells to activated and reducing tissue regeneration, we have analysed 11 different histone posttranslational modifications (PTMs), PTM enzymes associated with remodelling neutrophil chromatin, and H3K4me3 ChIP-Seq Gene Ontology analysis focusing on the processes related to histone PTMs. These findings were verified by extrapolation to adequate clinical status, using neutrophils derived from the patients with sepsis (systemic septic inflammation with LPS-stimulated neutrophils), neuromyelitis optical spectrum disorders (aseptic inflammation with pre-activated neutrophils) and periodontitis (local self-limiting septic inflammation with IL-10-positive neutrophils). RESULTS Physiological activation of neutrophils comprises a pre-activation characterised by histone H3K27ac and H3K4me1, which position enhancers; direct LPS exposure is induced explicitly by H3K4me3 which marked Transcription Start Site (TSS) regions and low-level of H3K9me3, H3K79me2 and H3K27me3 which, in turn, marked repressed genes. Contrary to antimicrobial action, IL-10 positively induced levels of H3S10p and negatively H3K9me3, which characterised processes related to the activation of genes within heterochromatin mediated by CHD1 and H3K9me3 specific demethylase JMJD2A. IL-10 protects changes within histone PTMs induced by TNF or LPS that affected H3K4me3-specific methyltransferase SETD1A and MLL1. Neutrophils previously exposed to inflammatory factors become unvulnerable to IL-10 because previous LPS stimulation interrupts TSS regions marked by H3K4me3 of CHD1 and JMJD2A genes. Therefore, LPS-activated neutrophils are disabled to induce CHD1/JMJD2A enzymes by IL-10, making this process irreversible. Because transcription of JMJD2A and CHD1 also depends on TSS positioning by H3K4me3, neutrophils before LPS stimulation become insensitive to IL-10. CONCLUSION Neutrophils, once pre-activated by TNF or directly stimulated by LPS, become insensitive to the anti-inflammatory effects of IL-10, and vice versa; IL-10 protects neutrophils against these proinflammatory stimuli. This phenomenon is responsible for disturbing the natural process of resolving inflammation and tissue regeneration.

Abstract
Somatic cell nuclear transfer (SCNT) is a powerful technique, although challenging, to study reprograming into the totipotent state of differentiated nuclei in mammals. This procedure was initially applied in farm animals, then rodents, and more recently in primates. Nuclear transfer of embryonic stem cells is known to be more efficient, but many types of somatic cells have now been successfully reprogramed with this procedure. Moreover, SCNT reprograming is more effective on a per cell basis than induced Pluripotent Stem Cells (iPSC) and provides interesting clues regarding the underlying processes. In this chapter, we describe the protocol of nuclear transfer in mouse that combines cell cycle synchronization of the donor cells, enucleation of metaphase II oocyte and Piezo-driven injection of a donor cell nucleus followed by activation of the reconstructed embryos and nonsurgical transfer into pseudo-pregnant mice. Moreover, this protocol includes two facultative steps to erase the epigenetic "memory" of the donor cells and improve chromatin remodeling by histones modifications targeting.

Abstract
Background Currently, the efficient production of chimeric mice and their survival are still challenging. Recent researches have indicated that preimplantation embryo culture media and manipulation lead to abnormal methylation of histone in the H19/Igf2 promotor region and consequently alter their gene expression pattern. This investigation was designed to evaluate the relationship between the methylation state of histone H3 and H19/Igf2 expression in mice chimeric blastocysts. Methods Mouse 129/Sv embryonic stem cells (mESCs) expressing the green fluorescent protein (mESCs-GFP) were injected into the perivitelline space of 2.5 days post-coitis (dpc) embryos (C57BL/6) using a micromanipulator. H3K4 and H3K9 methylation, and H19 and Igf2 expression was measured by immunocytochemistry and q-PCR, respectively, in blastocysts. Results Histone H3 trimethylation in H3K4 and H3K9 in chimeric blastocysts was significantly less and greater, respectively (p< 0.05), than in controls. H19 expression was significantly less (p< 0.05), while Igf2 expression was less, but not significantly so, in chimeric than in control blastocysts. Conclusion Our results showed, that the alteration ofH3K4me3 and H3K9me3 methylation, change H19/Igf2 expression in chimeric blastocysts.

Abstract
BACKGROUND Infertility is a common reproductive disorder, with male factor infertility accounting for approximately half of all cases. Taking a paternal perceptive, recent research has shown that sperm epigenetics, such as changes in DNA methylation, histone modification, chromatin structure, and noncoding RNA expression, can impact reproductive and offspring health. Importantly, environmental conditions during the preconception period has been demonstrated to shape sperm epigenetics. OBJECTIVES To provide an overview on epigenetic modifications that regulate normal gene expression and epigenetic remodeling that occurs during spermatogenesis, and to discuss the epigenetic alterations that may occur to the paternal germline as a consequence of preconception environmental conditions and exposures. MATERIALS AND METHODS We examined published literature available on databases (PubMed, Google Scholar, ScienceDirect) focusing on adult male preconception environmental exposures and sperm epigenetics in epidemiologic studies and animal models. RESULTS The preconception period is a sensitive developmental window in which a variety of exposures such as toxicants, nutrition, drugs, stress, and exercise, affects sperm epigenetics. DISCUSSION AND CONCLUSION Understanding the environmental legacy of the sperm epigenome during spermatogenesis will enhance our understanding of reproductive health and improve reproductive success and offspring well-being.

Abstract
Upon fertilization in mammals the gametes are reprogrammed to create a totipotent zygote, a process that involves de novo establishment of chromatin domains. A major feature occurring during preimplantation development is the dramatic remodeling of constitutive heterochromatin, although the functional relevance of this is unknown. Here we show that heterochromatin establishment relies on the stepwise expression and regulated activity of Suv39h enzymes. Enforcing precocious acquisition of constitutive heterochromatin results in compromised development and epigenetic reprogramming, demonstrating that heterochromatin remodeling is essential for natural reprogramming at fertilization. We find that de novo H3K9 trimethylation in the paternal pronucleus after fertilization is catalyzed by Suv39h2 and that pericentromeric RNAs inhibit Suv39h2 activity and reduce H3K9me3. De novo H3K9me3 is initially non-repressive for gene expression but instead can bookmark promoters for compaction. Overall, we uncover the functional importance for the restricted transmission of constitutive heterochromatin during reprogramming and a non-repressive role for H3K9me3.

Abstract
When reflecting about cell fate commitment we think of differentiation. Be it during embryonic development or in an adult stem cell niche, where cells of a higher potency specialize and cell fate decisions are taken. Under normal circumstances this process is definitive and irreversible. Cell fate commitment is achieved by the establishment of cell-type-specific transcriptional programmes, which in turn are guided, reinforced, and ultimately locked-in by epigenetic mechanisms. Yet, this plunging drift in cellular potency linked to epigenetically restricted access to genomic information is problematic for reproduction. Particularly in mammals where germ cells are not set aside early on like in other species. Instead they are rederived from the embryonic ectoderm, a differentiating embryonic tissue with somatic epigenetic features. The epigenomes of germ cell precursors are efficiently reprogrammed against the differentiation trend, only to specialize once more into highly differentiated, sex-specific gametes: oocyte and sperm. Their differentiation state is reflected in their specialized epigenomes, and erasure of these features is required to enable the acquisition of the totipotent cell fate to kick start embryonic development of the next generation. Recent technological advances have enabled unprecedented insights into the epigenetic dynamics, first of DNA methylation and then of histone modifications, greatly expanding the historically technically limited understanding of this processes. In this chapter we will focus on the details of embryonic epigenetic reprogramming, a cell fate determination process against the tide to a higher potency.

Abstract
Successful mammalian development requires descendants of single-cell zygotes to differentiate into diverse cell types even though they contain the same genetic material. Preimplantation dynamics are first driven by the necessity of reprogramming haploid parental epigenomes to reach a totipotent state. This process requires extensive erasure of epigenetic marks shortly after fertilization. During the few short days after formation of the zygote, epigenetic programs are established and are essential for the first lineage decisions and differentiation. Here we review the current understanding of DNA methylation and histone modification dynamics responsible for these early changes during mammalian preimplantation development. In particular, we highlight insights that have been gained through next-generation sequencing technologies comparing human embryos to other models as well as the recent discoveries of active DNA demethylation mechanisms at play during preimplantation.

Abstract
It is very important for embryologists to understand how parental inherited genomes are reprogrammed after fertilisation in order to obtain good-quality embryos that will sustain further development. In mammals, it is now well established that important epigenetic modifications occur after fertilisation. Although gametes carry special epigenetic signatures, they should attain embryo-specific signatures, some of which are crucial for the production of healthy embryos. Indeed, it appears that proper establishment of different epigenetic modifications and subsequent scaffolding of the chromatin are crucial steps during the first cleavages. This ‘reprogramming’ is promoted by the intimate contact between the parental inherited genomes and the oocyte cytoplasm after fusion of the gametes. This review introduces two main epigenetic players, namely histone post-translational modifications and DNA methylation, and highlights their importance during early embryonic development.

Abstract
Aberrant post-translational modifications of proteins contribute markedly to the abnormal characteristics of cloned embryos. This review summarizes aberrant aspects of protein modifications and protein interactions, taking an inside-outside view to the cell. These aberrant aspects affect a range of processes including the control of chromatin structure, expression of pluripotency genes, propagation of epigenetic inheritance, protein trafficking, localization and signaling, cytoskeletal structure, mitosis, and correct localization of membrane proteins. By observing these aberrant features of cloned embryos, how they arise, and their impacts on development, it is possible to gain insight into normal development and identify novel strategies for enhancing cloning outcomes.

Abstract
In mammals, epigenetic modifications are globally rearranged after fertilization, when gametes fuse to form the embryo. While gametes carry special epigenetic signatures and a unique nuclear organization, they attain embryo-specific patterns after fertilization. This "reprogramming" is promoted by intimate contact between the parental inherited genomes and the oocyte cytoplasm over the first cell cycles of development. Although the mechanisms of this reprogramming remain poorly understood, it appears that the particular epigenetic landscape established after fertilization is essential for further development. This review looks at histone post-translational modifications, focusing on their functions in chromatin organization and their role in nuclear architecture during mouse embryonic development. Epigenetic changes linked to the use of assisted reproductive technologies are also considered.
