Abstract
Mastitis is among the main reasons women cease breastfeeding, which leads to them supplementing breast milk with artificial formula. In farm animals, mastitis results in significant economic losses and the premature culling of some animals. Nevertheless, researchers do not know enough about the effect of inflammation on the mammary gland. This article discusses the changes to DNA methylation in mouse mammary tissue caused by lipopolysaccharide-induced inflammation (4 h post-injection of lipopolysaccharide). We analysed the expression of some genes related to mammary gland function, epigenetic regulation, and the immune response. The analysis focused on three comparisons: inflammation during the first lactation, inflammation during second lactation with no history of inflammation, and inflammation during second lactation with previous inflammation. We identified differentially methylated cytosines (DMCs), differentially methylated regions (DMRs), and some differentially expressed genes (DEGs) for each comparison. The three comparisons shared some DEGs; however, few DMCs and only one DMR were shared. These observations suggest that inflammation is one of several factors affecting epigenetic regulation during successive lactations. Furthermore, the comparison between animals in second lactation with and without inflammation, with no inflammation history during first lactation showed a different pattern compared to the other conditions in this experiment. This indicates that inflammation history plays an important role in determining epigenetic changes. The data presented in this study suggest that lactation rank and previous inflammation history are equally important when explaining mammary tissue gene expression and DNA methylation changes.Abbreviations: RRBS, reduced representation bisulfite sequencing; RT-qPCR, real-time quantitative polymerase chain reaction; MEC, mammary epithelial cells; TSS, transcription start site; TTS, transcription termination site; UTR, untranslated region; SINE, short interspersed nuclear element; LINE, long interspersed nuclear element; CGI, CpG island; DEG, differentially expressed gene; DMC, differentially methylated cytosine; DMR, differentially methylated region; GO term, gene ontology term; MF, molecular function; BP, biological process.

Abstract
Mastitis is among the main reasons women cease breastfeeding. In farm animals, mastitis results in significant economic losses and the premature culling of some animals. Nevertheless, the effect of inflammation on the mammary gland is not completely understood. This article discusses the changes to DNA methylation in mouse mammary tissue caused by lipopolysaccharide-induced inflammation after in vivo intramammary challenges and the differences in DNA methylation between 1st and 2nd lactations. Lactation rank induces 981 differential methylations of cytosines (DMCs) in mammary tissue. Inflammation in 1st lactation compared to inflammation in 2nd lactation results in the identification of 964 DMCs. When comparing inflammation in 1st vs. 2nd lactations with previous inflammation history, 2590 DMCs were identified. Moreover, Fluidigm PCR data show changes in the expression of several genes related to mammary function, epigenetic regulation, and the immune response. We show that the epigenetic regulation of two successive physiological lactations is not the same in terms of DNA methylation and that the effect of lactation rank on DNA methylation is stronger than that of the onset of inflammation. The conditions presented here show that few DMCs are shared between comparisons, suggesting a specific epigenetic response depending on lactation rank, the presence of inflammation, and even whether the cells had previously suffered inflammation. In the long term, this information could lead to a better understanding of the epigenetic regulation of lactation in both physiological and pathological conditions.Abbreviations: RRBS, reduced representation bisulphite sequencing; RT-qPCR, real-time quantitative polymerase chain reaction; MEC, mammary epithelial cells; MaSC, mammary stem cell; TSS, transcription start site; TTS, transcription termination site; UTR, untranslated region; SINE, short interspersed nuclear element; LINE, long interspersed nuclear element; CGI, CpG island; DEG, differentially expressed gene; DMC, differentially methylated cytosine; DMR, differentially methylated region; GO term, gene ontology term; MF, molecular function; BP, biological process.

Abstract
Animal toxicological studies often fail to mimic the complexity of the human exposome, associating low doses, combined molecules and long-term exposure. Since the reproductive potential of a woman begins in the fetal ovary, the literature regarding the disruption of its reproductive health by environmental toxicants remains limited. Studies draw attention to follicle development, a major determinant for the quality of the oocyte, and the preimplantation embryo, as both of them are targets for epigenetic reprogramming. The "Folliculogenesis and Embryo Development EXPOsure to a mixture of toxicants: evaluation in the rabbit model" (FEDEXPO) project emerged from consideration of these limitations and aims to evaluate in the rabbit model the impacts of an exposure to a mixture of known and suspected endocrine disrupting chemicals (EDCs) during two specific windows, including folliculogenesis and preimplantation embryo development. The mixture combines eight environmental toxicants, namely perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), 2,2'4,4'-tetrabromodiphenyl ether (BDE-47), di(2-ethylhexyl) phthalate (DEHP) and bisphenol S (BPS), at relevant exposure levels for reproductive-aged women based on biomonitoring data. The project will be organized in order to assess the consequences of this exposure on the ovarian function of the directly exposed F0 females and monitor the development and health of the F1 offspring from the preimplantation stage. Emphasis will be made on the reproductive health of the offspring. Lastly, this multigenerational study will also tackle potential mechanisms for the inheritance of health disruption via the oocyte or the preimplantation embryo.

Abstract
Estrogens are steroid hormones produced by the aromatization of androgens by the aromatase enzyme, encoded by the CYP19A1 gene. Although generally referred to as "female sex hormones", estrogen is also produced in the adult testes of many mammals, including humans. To better understand the function of estrogens in the male, we used the rabbit model which is an important biomedical model. First, the expression of CYP19A1 transcripts was localized mainly in meiotic germ cells. Thus, testicular estrogen appears to be produced inside the seminiferous tubules. Next, the cells expressing ESR1 and ESR2 were identified, showing that estrogens could exert their function on post-meiotic germ cells in the tubules and play a role during sperm maturation, since ESR1 and ESR2 were detected in the cauda epididymis. Then, CRISPR/Cas9 CYP19A1-/- genetically modified rabbits were analyzed. CYP19A1-/- males showed decreased fertility with lower sperm count associated with hypo-spermatogenesis and lower spermatid number. Germ/sperm cell DNA methylation was unchanged, while sperm parameters were affected as CYP19A1-/- males exhibited reduced sperm motility associated with increased flagellar defects. In conclusion, testicular estrogens could be involved in the spermatocyte-spermatid transition in the testis, and in the acquisition of sperm motility in the epididymis.

Abstract
Enhanced pre-pubertal nutrition in Holstein bulls increased reproductive hormone production and sperm production potential with no negative effects on sperm quality. However, recent trends in human epigenetic research have identified pre-pubertal period to be critical for epigenetic reprogramming in males. Our objective was to evaluate the methylation changes in sperm of bulls exposed to different pre-pubertal diets. One-week-old Holstein bull calves (n = 9), randomly allocated to 3 groups, were fed either a high, medium or low diet (20%, 17% or 12.2% crude protein and 67.9%, 66% or 62.9% total digestible nutrients, respectively) from 2 to 32 weeks of age, followed by medium nutrition. Semen collected from bulls at two specific time points, i.e. 55-59 and 69-71 weeks, was diluted, cryopreserved and used for reduced representation bisulfite sequencing. Differential methylation was detected for dietary treatment, but minimal differences were detected with age. The gene ontology term, "regulation of Rho protein signal transduction", implicated in sperm motility and acrosome reaction, was enriched in both low-vs-high and low-vs-medium datasets. Furthermore, several genes implicated in early embryo and foetal development showed differential methylation for diet. Our results therefore suggest that sperm epigenome keeps the memory of diet during pre-pubertal period in genes important for spermatogenesis, sperm function and early embryo development.

Abstract
BACKGROUND Conflicting results regarding alterations to sperm DNA methylation in cases of spermatogenesis defects, male infertility and poor developmental outcomes have been reported in humans. Bulls used for artificial insemination represent a relevant model in this field, as the broad dissemination of bull semen considerably alleviates confounding factors and enables the precise assessment of male fertility. This study was therefore designed to assess the potential for sperm DNA methylation to predict bull fertility. RESULTS A unique collection of 100 sperm samples was constituted by pooling 2-5 ejaculates per bull from 100 Montbéliarde bulls of comparable ages, assessed as fertile (n = 57) or subfertile (n = 43) based on non-return rates 56 days after insemination. The DNA methylation profiles of these samples were obtained using reduced representation bisulfite sequencing. After excluding putative sequence polymorphisms, 490 fertility-related differentially methylated cytosines (DMCs) were identified, most of which were hypermethylated in subfertile bulls. Interestingly, 46 genes targeted by DMCs are involved in embryonic and fetal development, sperm function and maturation, or have been related to fertility in genome-wide association studies; five of these were further analyzed by pyrosequencing. In order to evaluate the prognostic value of fertility-related DMCs, the sperm samples were split between training (n = 67) and testing (n = 33) sets. Using a Random Forest approach, a predictive model was built from the methylation values obtained on the training set. The predictive accuracy of this model was 72% on the testing set and 72% on individual ejaculates collected from an independent cohort of 20 bulls. CONCLUSION This study, conducted on the largest set of bull sperm samples so far examined in epigenetic analyses, demonstrated that the sperm methylome is a valuable source of male fertility biomarkers. The next challenge is to combine these results with other data on the same sperm samples in order to improve the quality of the model and better understand the interplay between DNA methylation and other molecular features in the regulation of fertility. This research may have potential applications in human medicine, where infertility affects the interaction between a male and a female, thus making it difficult to isolate the male factor.

Abstract
Semen infertility or sub-fertility, whether in humans or livestock species, remains a major concern for clinicians and technicians involved in reproduction. Indeed, they can cause tragedies in human relationships or have a dramatic overall negative impact on the sustainability of livestock breeding. Understanding and predicting semen fertility issues is therefore crucial and quality control procedures as well as biomarkers have been proposed to ensure sperm fertility. However, their predictive values appeared to be too limited and additional relevant biomarkers are still required to diagnose sub-fertility efficiently. During the last decade, the study of molecular mechanisms involved in spermatogenesis and sperm maturation highlighted the regulatory role of a variety of small non-coding RNAs (sncRNAs) and led to the discovery that sperm sncRNAs comprise both remnants from spermatogenesis and post-testicular sncRNAs acquired through interactions with extracellular vesicles along epididymis. This has led to the hypothesis that sncRNAs may be a source of relevant biomarkers, associated either with sperm functionality or embryo development. This review aims at providing a synthetic overview of the current state of knowledge regarding implication of sncRNA in spermatogenesis defects and their putative roles in sperm maturation and embryo development, as well as exploring their use as fertility biomarkers.

Abstract
Background During epididymal transit, spermatozoa go through several functional maturation steps, resulting from interactions with epididymal secretomes specific to each region. In particular, the sperm membrane is under constant remodeling, with sequential attachment and shedding of various molecules provided by the epididymal lumen fluid and epididymosomes, which also deliver sncRNA cargo to sperm. As a result, the payload of sperm sncRNAs changes during the transit from the epididymis caput to the cauda. This work was designed to study the dynamics of cattle sperm sncRNAs from spermatogenesis to final maturation. Results Comprehensive catalogues of sperm sncRNAs were obtained from testicular parenchyma, epididymal caput, corpus and cauda, as well as ejaculated semen from three Holstein bulls. The primary cattle sncRNA sperm content is markedly remodeled as sperm mature along the epididymis. Expression of piRNAs, which are abundant in testis parenchyma, decreases dramatically at epididymis. Conversely, sperm progressively acquires miRNAs, rsRNAs, and tsRNAs along epididymis, with regional specificities. For instance, miRNAs and tsRNAs are enriched in epididymis cauda and ejaculated sperm, while rsRNA expression peaks at epididymis corpus. In addition, epididymis corpus contains mainly 20 nt long piRNAs, instead of 30 nt in all other locations. Beyond the bulk differences in abundance of sncRNAs classes, K-means clustering was performed to study their spatiotemporal expression profile, highlighting differences in specific sncRNAs and providing insights into their putative biological role at each maturation stage. For instance, Gene Ontology analyses using miRNA targets highlighted enriched processes such as cell cycle regulation, response to stress and ubiquitination processes in testicular parenchyma, protein metabolism in epididymal sperm, and embryonic morphogenesis in ejaculated sperm. Conclusions Our findings confirm that the sperm sncRNAome does not simply reflect a legacy of spermatogenesis. Instead, sperm sncRNA expression shows a remarkable level of plasticity resulting probably from the combination of multiple factors such as loss of the cytoplasmic droplet, interaction with epididymosomes, and more surprisingly, the putative in situ production and/or modification of sncRNAs by sperm. Given the suggested role of sncRNA in epigenetic trans-generational inheritance, our detailed spatiotemporal analysis may pave the way for a study of sperm sncRNAs role in embryo development.

Abstract
In humans and model species, alterations of sperm DNA methylation patterns have been reported in cases of spermatogenesis defects, male infertility and exposure to toxins or nutritional challenges, suggesting that a memory of environmental or physiological changes is recorded in the sperm methylome. The objective of this study was to ascertain if early life plane of nutrition could have a latent effect on DNA methylation patterns in sperm produced post-puberty. Holstein-Friesian calves were assigned to either a high (H) or moderate (M) plane of nutrition for the first 24 weeks of age, then reassigned to the M diet until puberty, resulting in HM and MM groups. Sperm DNA methylation patterns from contrasted subgroups of bulls in the HM (ejaculates recovered at 15 months of age; n = 9) and in the MM (15 and 16 months of age; n = 7 and 9, respectively) were obtained using Reduced Representation Bisulfite Sequencing. Both 15 and 16 months were selected in the MM treatment as these bulls reached puberty approximately 1 month after the HM bulls. Hierarchical clustering demonstrated that inter-individual variability unrelated to diet or age dominated DNA methylation profiles. While the comparison between 15 and 16 months of age revealed almost no change, 580 differentially methylated CpGs (DMCs) were identified between the HM and MM groups. Differentially methylated CpGs were mostly hypermethylated in the HM group, and enriched in endogenous retrotransposons, introns, intergenic regions, and shores and shelves of CpG islands. Furthermore, genes involved in spermatogenesis, Sertoli cell function, and the hypothalamic-pituitary-gonadal axis were targeted by differential methylation when HM and MM groups were compared at 15 months of age, reflecting the earlier timing of puberty onset in the HM bulls. In contrast, the genes still differentially methylated in MM bulls at 16 months of age were enriched for ATP-binding molecular function, suggesting that changes to the sperm methylome could persist even after the HM and MM bulls reached a similar level of sexual maturity. Together, results demonstrate that enhanced plane of nutrition in pre-pubertal calves associated with advanced puberty induced modest but persistent changes in sperm DNA methylation profiles after puberty.

Abstract
Background Mature sperm carry thousands of RNAs, including mRNAs, lncRNAs, tRNAs, rRNAs and sncRNAs, though their functional significance is still a matter of debate. Growing evidence suggests that sperm RNAs, especially sncRNAs, are selectively retained during spermiogenesis or specifically transferred during epididymis maturation, and are thus delivered to the oocyte at fertilization, providing resources for embryo development. However , a deep characterization of the sncRNA content of bull sperm and its expression profile across breeds is currently lacking. To fill this gap, we optimized a guanidinium–Trizol total RNA extraction protocol to prepare high-quality RNA from frozen bull sperm collected from 40 representative bulls from six breeds. Deep sequencing was performed (40 M single 50-bp reads per sample) to establish a comprehensive repertoire of cattle sperm sncRNA. Results Our study showed that it comprises mostly piRNAs (26%), rRNA fragments (25%), miRNAs (20%) and tRNA fragments (tsRNA, 14%). We identified 5p-halves as the predominant tsRNA subgroup in bull sperm, originating mostly from Gly and Glu isoacceptors. Our study also increased by ~ 50% the sperm repertoire of known miRNAs and identified 2022 predicted miRNAs. About 20% of sperm miRNAs were located within genomic clusters, expanding the list of known polycistronic pri-miRNA clusters and defining several networks of co-expressed miRNAs. Strikingly, our study highlighted the great diversity of isomiRs, resulting mainly from deletions and non-templated additions (A and U) at the 3p end. Substitutions within miRNA sequence accounted for 40% of isomiRs, with G>A, U>C and C>U substitutions being the most frequent variations. In addition, many sncRNAs were found to be differentially expressed across breeds. Conclusions Our study provides a comprehensive overview of cattle sperm sncRNA, and these findings will pave the way for future work on the role of sncRNAs in embryo development and their relevance as biomarkers of semen fertility.

Abstract
Highly differentiated mature spermatozoa carry not only genetic but also epigenetic information that is to be transmitted to the embryo. DNA methylation is one epigenetic actor associated with sperm nucleus compaction, gene silencing, and prepatterning of embryonic gene expression. Therefore, the stability of this mark toward reproductive biotechnologies is a major issue in animal production. The present work explored the impact of hormonal induction of spermiation and sperm cryopreservation in two cyprinids, the goldfish (Carassius auratus) and the zebrafish (Danio rerio), using LUminometric Methylation Assay (LUMA). We showed that while goldfish hormonal treatment did increase sperm production, it did not alter global DNA methylation of spermatozoa. Different sperm samples repeatedly collected from the same males for 2 months also showed the same global DNA methylation level. Similarly, global DNA methylation was not affected after cryopreservation of goldfish spermatozoa with methanol, whereas less efficient cryoprotectants (dimethylsulfoxide and 1,2-propanediol) decreased DNA methylation. In contrast, cryopreservation of zebrafish spermatozoa with methanol induced a slight, but significant, increase in global DNA methylation. In the less compact nuclei, that is, goldfish fin somatic cells, cryopreservation did not change global DNA methylation regardless of the choice of cryoprotectant. To conclude, global DNA methylation is a robust parameter with respect to biotechnologies such as hormonal induction of spermiation and sperm cryopreservation, but it can be altered when the best sperm manipulation conditions are not met.

Abstract
According to the “developmental origins of health and disease” (DOHaD) concept, maternal obesity predisposes the offspring to non-communicable diseases in adulthood. While a preconceptional weight loss (WL) is recommended for obese women, its benefits on the offspring have been poorly addressed. We evaluated whether preconceptional WL was able to reverse the adverse effects of maternal obesity in a mouse model, exhibiting a modification of foetal growth and of the expression of genes encoding epigenetic modifiers in liver and placenta. We tracked metabolic and olfactory behavioural trajectories of offspring born to control, obese or WL mothers. After weaning, the offspring were either put on a control diet (CD) or a high-fat (HFD). After only few weeks of HFD, the offspring developed obesity, metabolic alterations and olfactory impairments, independently of maternal context. However, male offspring born to obese mother gained even more weight under HFD than their counterparts born to lean mothers. Preconceptional WL normalized the offspring metabolic phenotypes but had unexpected effects on olfactory performance: a reduction in olfactory sensitivity, along with a lack of fasting-induced, olfactory-based motivation. Our results confirm the benefits of maternal preconceptional WL for male offspring metabolic health but highlight some possible adverse outcomes on olfactory-based behaviours.

Abstract
BACKGROUND It is well established that obesity is associated with dysregulation of the ratio between the two major adipokines leptin and adiponectin. Furthermore, it was recently reported that maternal obesity has a significant impact on placental development. Leptin and adiponectin are present at the fetal-maternal interface and are involved in the development of a functional placenta. However, less is known about leptin and adiponectin's involvement in the placental alterations described in obese women. Hence, the objective of the present study was to characterize the placental expression and DNA methylation of these two adipokine systems (ligands and receptors) in obese women. RESULTS Biopsies were collected from the fetal and maternal sides of third-trimester placenta in obese and non-obese (control) women. In both groups, leptin levels were higher on the fetal side than the maternal side, suggesting that this cytokine has a pivotal role in fetal growth. Secondly, maternal obesity (in the absence of gestational diabetes) was associated with (i) elevated DNA methylation of the leptin promoter on fetal side only, (ii) hypomethylation of the adiponectin promoter on the maternal side only, (iii) significantly low levels of leptin receptor protein (albeit in the absence of differences in mRNA levels and promoter DNA methylation), (iv) significantly low levels of adiponectin receptor 1 mRNA expression on the maternal side only, and (v) elevated DNA methylation of the adiponectin receptor 2 promoter on the maternal side only. CONCLUSION Our present results showed that maternal obesity is associated with the downregulation of both leptin/adiponectin systems in term placenta, and thus a loss of the beneficial effects of these two adipokines on placental development. Maternal obesity was also associated with epigenetic changes in leptin and adiponectin systems; this highlighted the molecular mechanisms involved in the placenta's adaptation to a harmful maternal environment.

Abstract
BACKGROUND Spermatozoa have a remarkable epigenome in line with their degree of specialization, their unique nature and different requirements for successful fertilization. Accordingly, perturbations in the establishment of DNA methylation patterns during male germ cell differentiation have been associated with infertility in several species. While bull semen is widely used in artificial insemination, the literature describing DNA methylation in bull spermatozoa is still scarce. The purpose of this study was therefore to characterize the bull sperm methylome relative to both bovine somatic cells and the sperm of other mammals through a multiscale analysis. RESULTS The quantification of DNA methylation at CCGG sites using luminometric methylation assay (LUMA) highlighted the undermethylation of bull sperm compared to the sperm of rams, stallions, mice, goats and men. Total blood cells displayed a similarly high level of methylation in bulls and rams, suggesting that undermethylation of the bovine genome was specific to sperm. Annotation of CCGG sites in different species revealed no striking bias in the distribution of genome features targeted by LUMA that could explain undermethylation of bull sperm. To map DNA methylation at a genome-wide scale, bull sperm was compared with bovine liver, fibroblasts and monocytes using reduced representation bisulfite sequencing (RRBS) and immunoprecipitation of methylated DNA followed by microarray hybridization (MeDIP-chip). These two methods exhibited differences in terms of genome coverage, and consistently, two independent sets of sequences differentially methylated in sperm and somatic cells were identified for RRBS and MeDIP-chip. Remarkably, in the two sets most of the differentially methylated sequences were hypomethylated in sperm. In agreement with previous studies in other species, the sequences that were specifically hypomethylated in bull sperm targeted processes relevant to the germline differentiation program (piRNA metabolism, meiosis, spermatogenesis) and sperm functions (cell adhesion, fertilization), as well as satellites and rDNA repeats. CONCLUSIONS These results highlight the undermethylation of bull spermatozoa when compared with both bovine somatic cells and the sperm of other mammals, and raise questions regarding the dynamics of DNA methylation in bovine male germline. Whether sperm undermethylation has potential interactions with structural variation in the cattle genome may deserve further attention.

Abstract
The effect of the Developmental Origins of Health and Disease on the spread of non-communicable diseases is recognised by world agencies such as the United Nations and the World Health Organization. Early environmental effects on offspring phenotype also apply to domestic animals and their production traits. Herein, we show that maternal nutrition not only throughout pregnancy, but also in the periconception period can affect offspring phenotype through modifications of gametes, embryos and placental function. Because epigenetic mechanisms are key processes in mediating these effects, we propose that the study of epigenetic marks in gametes may provide additional information for domestic animal selection.

Abstract
A major unresolved issue in the cloning of mammals by somatic cell nuclear transfer (SCNT) is the mechanism by which the process fails after embryos are transferred to the uterus of recipients before or during the implantation window. We investigated this problem by using RNA sequencing (RNA-seq) to compare the transcriptomes in cattle conceptuses produced by SCNT and artificial insemination (AI) at day (d) 18 (preimplantation) and d 34 (postimplantation) of gestation. In addition, endometrium was profiled to identify the communication pathways that might be affected by the presence of a cloned conceptus, ultimately leading to mortality before or during the implantation window. At d 18, the effects on the transcriptome associated with SCNT were massive, involving more than 5,000 differentially expressed genes (DEGs). Among them are 121 genes that have embryonic lethal phenotypes in mice, cause defects in trophoblast and placental development, and/or affect conceptus survival in mice. In endometria at d 18, <0.4% of expressed genes were affected by the presence of a cloned conceptus, whereas at d 34, ∼36% and <0.7% of genes were differentially expressed in intercaruncular and caruncular tissues, respectively. Functional analysis of DEGs in placental and endometrial tissues suggests a major disruption of signaling between the cloned conceptus and the endometrium, particularly the intercaruncular tissue. Our results support a "bottleneck" model for cloned conceptus survival during the periimplantation period determined by gene expression levels in extraembryonic tissues and the endometrial response to altered signaling from clones.

Abstract
Lactation performance is dependent on both the genetic characteristics and the environmental conditions surrounding lactating cows. However, individual variations can still be observed within a given breed under similar environmental conditions. The role of the environment between birth and lactation could be better appreciated in cloned cows, which are presumed to be genetically identical, but differences in lactation performance between cloned and noncloned cows first need to be clearly evaluated. Conflicting results have been described in the literature, so our aim was to clarify this situation. Nine cloned Prim' Holstein cows were produced by the transfer of nuclei from a single fibroblast cell line after cell fusion with enucleated oocytes. The cloned cows and 9 noncloned counterparts were raised under similar conditions. Milk production and composition were recorded monthly from calving until 200d in milk. At 67d in milk, biopsies were sampled from the rear quarter of the udder, their mammary epithelial cell content was evaluated, and mammary cell renewal, RNA, and DNA were then analyzed in relevant samples. The results showed that milk production did not differ significantly between cloned and noncloned cows, but milk protein and fat contents were less variable in cloned cows. Furthermore, milk fat yield and contents were lower in cloned cows during early lactation. At around 67 DIM, milk fat and protein yields, as well as milk fat, protein, and lactose contents, were also lower in cloned cows. These lower yields could be linked to the higher apoptotic rate observed in cloned cows. Apoptosis is triggered by insulin-like factor growth binding protein 5 (IGFBP5) and plasminogen activator inhibitor (PAI), which both interact with CSN1S2. During our experiments, CSN1S2 transcript levels were lower in the mammary gland of cloned cows. The mammary cell apoptotic rate observed in cloned cows may have been related to the higher levels of DNA (cytosine-5-)-methyltransferase 1 (DNMT1) transcripts, coding for products that maintain the epigenetic status of cells. We conclude, therefore, that milk production in cloned cows differs slightly from that of noncloned cows. These differences may be due, in part, to a higher incidence of subclinical mastitis. They were associated with differences in cell apoptosis and linked to variations in DNMT1 mRNA. However, milk protein and fat contents were more similar among cloned cows than among noncloned cows.

Abstract
The existence of non-genetic and non-cultural mechanisms that transfer information on the memory of parental exposures to various environments, determining the reactivity of the following generations to their environments during their life, are of growing interest. Yet fundamental questions remain about the nature, the roles and relative importance of epigenetic marks and processes, non-coding RNAs, or other mechanisms, and their persistence over generations. A model incorporating the various transmission systems, their cross-talks and windows of susceptibility to the environment as a function of sex/gender of parent and offspring, has yet to be built.

Abstract
According to the new paradigm of the Developpemental Origins of Health and Disease (DOHaD), the environmental factors to which an individual is exposed throughout his life can leave an epigenetic footprint on the genome. A crucial period is the early development, where the epigenome is particularly sensitive to the effects of the environment, and during which the individual builds up his health capital that will enable him to respond more or less well to the vagaries of life. The research challenge is to decipher the modes of action and the epigenetic mechanisms put into play by environmental factors that lead to increased disease susceptibility or resilience. The challenge for health is to translate these scientific discoveries into action through, among others, the establishment of preventive recommendations to slow down the growing incidence of non communicable diseases.

Abstract
Epigenetic marks, and especially DNA methylation, are at the interplay of both environmental and genetic factors. By facilitating the metabolic adaptation of highly selected rent animals to their environment, DNA methylation could contribute to the phenotypic differences observed between breeds. The aim of this study was to assess to which extent the methylome of 2 specialised cattle breeds – the dairy breed Holstein and the beef breed Japanese Black – could show some variability. We focused on the liver, which has a central role in metabolism and is therefore most susceptible to be affected by genetic and environmental variations. For each breed, both cloned and noncloned animals were included in the study. We used 9 adult Holstein cows aged from 5 to 15 years (5 healthy clones generated from ear skin fibroblasts of 4 genotypes, 2 cell donors obtained by AI and 2 other AI controls of unrelated genotypes, and 11 Japanese Black cows aged from 4 to 10 years (5 healthy clones generated from cumulus cells of one genotype and 6 AI controls of unrelated genotypes). The Holstein breed and Japanese Black breed were therefore represented by 6 and 7 genotypes, respectively. Liver samples were snap-frozen after slaughtering, and genomic DNA was extracted. To identify methylated regions, we used immunoprecipitation of methylated DNA followed by hybridization on a bovine promoter microarray (MeDIP-chip). The microarray targets the upstream region (–2000 to +1360 bp) of 21 416 genes (UMD3.1 assembly). After normalization of the data, enriched probes were identified using ChIPmix (Martin-Magniette et al. 2008). Results of exploratory analysis, including correlation clustering and principal component analysis, show a clear separation between the two breeds. A statistical test based on differences in the proportion of the enriched probes was used to identify differentially methylated regions (DMR) related to cloning and breed (Spatstat R package; http://www.spatstat.org/spatstat/). Only a restricted number of cloning-related DMR could be found (240). Interestingly, most of these DMR showed no overlap between Holstein and Japanese Black animals, maybe reflecting the different origin of the somatic cells used for cloning (fibroblasts v. cumulus cells). In contrast, we identified an important number of breed-related DMR (3642). These DMR were significantly enriched in genes involved in placental development and lactation, suggesting an adaptation of the two breeds to the different metabolic demand during gestation. Whether these epigenetic differences rely on environmental variations or genetic polymorphism remains to be elucidated.Research was supported by grants ANR-09-GENM-012-01 and Egide-JSPS Sakura 2012.

Once daily milking (ODM) induces a reduction in milk production when compared to twice daily milking (TDM). Unilateral ODM of one udder half and TDM of the other half, enables the study of underlying mechanisms independently of inter-individual variability (same genetic background) and of environmental factors. Our results show that in first-calf heifers three CpG, located 10 kb upstream from the CSN1S1 gene were methylated to 33, 34 and 28%, respectively, after TDM but these levels were higher after ODM, 38, 38 and 33%, respectively. These methylation levels were much lower than those observed in the mammary gland during pregnancy (57, 59 and 50%, respectively) or in the liver (74, 78 and 61%, respectively). The methylation level of a fourth CpG (CpG4), located close by (29% during TDM) was not altered after ODM. CpG4 methylation reached 39.7% and 59.5%, during pregnancy or in the liver, respectively. CpG4 is located within a weak STAT5 binding element, arranged in tandem with a second high affinity STAT5 element. STAT5 binding is only marginally modulated by CpG4 methylation, but it may be altered by the methylation levels of the three other CpG nearby. Our results therefore shed light on mechanisms that help to explain how milk production is almost, but not fully, restored when TDM is resumed (15.1±0.2 kg/day instead of 16.2±0.2 kg/day, p<0.01). The STAT5 elements are 100 bp away from a region transcribed in the antisense orientation, in the mammary gland during lactation, but not during pregnancy or in other reproductive organs (ovary or testes). We now need to clarify whether the transcription of this novel RNA is a consequence of STAT5 interacting with the CSN1S1 distal region, or whether it plays a role in the chromatin structure of this region.

Abstract
Reprogramming the differentiated cell to totipotency can be achieved following the introduction of its nucleus into an enucleated oocyte, a procedure known as cloning. We used cattle clones as a pertinent model to assess the inter-individual epigenetic variability and its consequences on phenotypes, including agronomically relevant traits and developmental pathologies. Indeed, the developmental defects frequently associated with cloning could be related to the insufficient extent of reprogramming, leading to perturbations of the nuclear microenvironment of the early embryo, with long-term consequences on the phenotype. Immunoprecipitation of methylated DNA following hybridization on a new bovine-specific tiling array (MeDIP-chip) was used to describe the epigenomic patterns affected by incomplete reprogramming. We first focused on the liver, because overgrowth of this organ is, to a certain extent, bound to global foetal overgrowth, which is often observed in clones. The microarray represents the 21 416 bovine genes currently annotated (UMD3.1 genome assembly). Each gene was tiled by 34 probes, on average, spanning upstream regions from –2000 to +1360 bp relative to the transcription start site. This microarray was hybridized with MeDIP samples from livers of normal Holstein animals obtained by AI (4 perinatal controls and 8 adults: 2 males and 10 females) and livers of female Holstein clones (7 perinatal clones from 2 different genotypes, either stillborn or suffering from severe pathologies, and 7 adult clones from 3 different genotypes, with normal to pathological phenotypes). After normalization of the data, enriched probes were identified using the ChIPmix method (Martin-Magniette et al. 2008 Bioinformatics) and located on the Ensembl Genome Browser. Results of exploratory analysis, including correlation clustering, principal components analysis (PCA), and independent components analysis (ICA), will be presented. A statistical test based on differences in the spatial distribution of the enriched probes along promoters was applied to the data, to associate epigenetic signatures to specific parameters (cloning, phenotype, stage, and genotype). Most promoters with more than 5 enriched probes across individuals showed a clustered distribution of the enriched probes. This local enrichment was highly conserved among individuals for 96% of the promoters, suggesting that most of the methylated regions were common to all animals. More interestingly, the distributions of the enriched probes showed inter-individual variability for 4% of the promoters in all samples. The identification and validation of these promoters is currently in progress.

Abstract
The Pou2 and Sox2 proteins are major transcription factors for development and cell differentiation. In teleosts, the expression patterns of pou2 or sox2 are different between species from distant families, suggesting different regulatory mechanisms of gene expression. In this study, we assessed the divergences among teleosts, including within closely related species. The pou2 and sox2 gene expression patterns were characterised over several developmental stages in a cyprinid model, i.e., the goldfish, and the potential regulation sites of these genes within teleost conserved regions were localised. During embryonic development, differences in the expression patterns between the goldfish and other teleosts, including zebrafish, were observed for both genes. The in silico analysis of the 5' flanking regions of the pou2 gene showed high conservation within teleosts, whereas the sox2 sequence diverged in tetraodontiforms. Certain putative cis regulatory elements were common to all teleosts, whereas others were found only in cyprinids. The analysis of the DNA methylation patterns of the pou2 and sox2 upstream sequences revealed that the studied CpG sites remained hypomethylated at all stages of embryo development in both genes. In contrast, in the adult fin, the studied CpG sites were hypermethylated in pou2 but not in sox2, suggesting the existence of methylation-sensitive regions in pou2. Overall, although most similarities at the level of the gene regulatory sites were found within cyprinids, the expression pattern of pou2 or sox2 during development differs between cyprinids species.

Abstract
AIMS The identification of specific biomarkers for colorectal cancer is of primary importance for early diagnosis. The aim of this study was to evaluate if methylation changes at the IGF2/H19 locus could be predictive for individuals at high risk for developing sporadic or hereditary colorectal cancer. MATERIALS & METHODS Quantitative methylation analysis using pyrosequencing was performed on three differentially methylated regions (DMRs): IGF2 DMR0 and DMR2 and the H19 DMR in DNA samples from sporadic colorectal cancer (n = 26), familial adenomatous polyposis (n = 35) and hereditary nonpolyposis colorectal cancer (n = 19) patients. RESULTS We report in this article for the first time, that in sporadic colorectal cancer tumor DNA both the IGF2 DMR0 and DMR2 are hypomethylated, while the H19 DMR retains its monoallelic methylation pattern. In lymphocyte DNA, a striking hypomethylation of nine contiguous correlated CpGs was found in the IGF2 DMR2 but only in familial adenomatous polyposis patients. CONCLUSION Methylation alterations at the IGF2 locus are more extensive than previously reported and DMR2 hypomethylation in lymphocyte DNA might be a specific epigenetic biomarker for familial adenomatous polyposis patients.

Abstract
Since the first success in sheep, the production of viable cloned offspring by somatic cell nuclear transfer (SCNT) is still doomed by a high incidence of pregnancy failure. In cattle, most gestation losses initially take place during the peri-implantation period. Then, abnormal placentation associated with fetal overgrowth (abnormal offspring syndrome) occurs in late pregnancy. As a consequence, IETS recommendations include regular ultrasound evaluation of SCNT pregnancies, with qualitative ultrasound evaluation of the placentomes, fetal movements and fluids being proposed. The objective of this study was to evaluate the use of new, quantitative parameters for the assessment of feto-placental development in AI and SCNT bovine pregnancies. Twenty-two heifers of 4 different breeds were used as SCNT recipients and 11 Holstein heifers were used as AI controls (C). All SCNT fetuses were produced as previously published in the laboratory, using the same fibroblast donor. Animals were scanned every 2 weeks from Day 150 using a Voluson-i (GE Medical Systems) with a transabdominal multifrequency probe (2.2 to 6.5 MHz), allowing automatic 3D volume and Doppler acquisition. Each time, 7 placentomes were scored from 0 to 3 according to echogenicity, general appearance and degree of oedema and their 2D surface was measured. Fetal intercostal width (ICW) was measured in a coronal view just behind the heart. Doppler velocimetry indices, pulsatility index (PI) and resistance index (RI) of one of the two fetal umbilical arteries were obtained and the diameters of the umbilical vessels were measured (UD). The 3D power Doppler was performed to obtain vascular index (VI), flow index (FI) and vascular flow index (VFI). Data were analysed by ANOVA with GraphPad Prism®. So far, 27 heifers have either delivered (n = 10 SCNT and 7 C) or pregnancies have been terminated because of abnormal offspring syndrome (n = 10 SCNT). One thousand five hundred and 197 placentomes have been analysed for 2D and 3D analyses, respectively. The mean placentome score is significantly higher (less normal) in SCNT compared with C (P < 0.0001) but does not vary according to gestational age. The placentome surface is also significantly larger in SCNT vs C (P < 0.0001) but also in SCNT that did not go to term vs those that were alive at birth (P < 0.002). Fetal ICW and UD are consistently larger in SCNT vs C (P < 0.0001) at all stages of pregnancy and there is a significant correlation (r2 = 0.81) between ICW at 15 days before term and birth weight. The PI and RI were not different between SCNT and C. Intra-operator reproducibility of 3D analyses was very high (intra-class correlation coefficient: 80 to 95% for a 95% confidence interval). There was no significant difference for VI, FI, or VFI between SCNT and C. Ongoing work taking into account pregnancy outcomes indicates that placentome scores are useful indicators of pregnancy outcome in SCNT pregnancies. In contrast, the abnormal vascularization observed by histology in SCNT placentomes does not appear to be accompanied by abnormal placental blood flow when analysed using quantitative 3D Doppler.

Abstract
In recent years, it has become increasingly clear that epigenetic regulation of gene expression is critical during embryo development and subsequently during pre- and post-natal life. The phenotype of an individual is the result of complex interactions between genotype and current, past and ancestral environment leading to a lifelong remodelling of its epigenome. Practically, if the genome was compared with the hardware in a computer, the epigenome would be the software that directs the computer's operation. This review points to the importance of epigenetic processes for genome function in various biological processes, such as embryo development and the expression of quantitative traits.

Abstract
Successful somatic cell nuclear transfer (SCNT) requires epigenetic reprogramming of a differentiated donor cell nucleus. Incorrect reprogramming of epigenetic markings such as DNA methylation is associated with compromised prenatal development and postnatal abnormalities. Clones that survive into adulthood, in contrast, are assumed to possess a normalized epigenome corresponding to their normal phenotype. To address this point, we used capillary electrophoresis to measure 5-methylcytosine (5mC) levels in leukocyte DNA of 38 healthy female bovine clones that represented five genotypes from the Simmental breed and four genotypes from the Holstein breed. The estimated variance in 5mC level within clone genotypes of both breeds [0.104, 95% confidence interval (CI): 0.070-0.168] was higher than between clone genotypes (0, CI: 0-0.047). We quantified the contribution of SCNT to this unexpected variability by comparing the 19 Simmental clones with 12 female Simmental monozygotic twin pairs of similar age. In Simmental clones, the estimated variability within genotype (0.0636, CI: 0.0358-0.127) was clearly higher than in twin pairs (0.0091, CI: 0.0047-0.0229). In clones, variability within genotype (0.0636) was again higher than between genotypes (0, CI: 0-0.077). Twins, in contrast, showed lower variability within genotypes (0.0091) than between genotypes (0.0136, CI: 0.00250-0.0428). Importantly, the absolute deviations of 5mC values of individual SCNT clones from their genotype means were fivefold increased in comparison to twins. Further comparisons with noncloned controls revealed DNA hypermethylation in most of the clones. The clone-specific variability in DNA methylation and DNA hypermethylation clearly show that healthy adult SCNT clones must be considered as epigenome variants.

Abstract
The H19 gene produces a non-coding RNA, which is abundantly expressed during embryonic development and down-regulated after birth. Although this gene was discovered over 20 years ago, its function has remained unclear. Only recently a role was identified for the non-coding RNA and/or its microRNA partner, first as a tumour suppressor gene in mice, then as a trans-regulator of a group of co-expressed genes belonging to the imprinted gene network that is likely to control foetal and early postnatal growth in mice. The mechanisms underlying this transcriptional or post-transcriptional regulation remain to be discovered, perhaps by identifying the protein partners of the full-length H19 RNA or the targets of the microRNA. This first in vivo evidence of a functional role for the H19 locus provides new insights into how genomic imprinting helps to control embryonic growth.

Abstract
DNA methylation marks, a key modification of imprinting, are erased in primordial germ cells and sex specifically re-established during gametogenesis. Abnormal epigenetic programming has been proposed as a possible mechanism compromising male fertility. We analysed by pyrosequencing the DNA methylation status of 47 CpGs located in differentially methylated regions (DMRs), the DMR0 and DMR2 of the IGF2 gene and in the 3rd and 6th CTCF-binding sites of the H19 DMR in human sperm from men with normal semen and patients with teratozoospermia (T) and/or oligo-astheno-teratozoospermia (OAT). All normal semen samples presented the expected high global methylation level for all CpGs analysed. In the teratozoospermia group, 11 of 19 patients presented a loss of methylation at variable CpG positions either in the IGF2 DMR2 or in both the IGF2 DMR2 and the 6th CTCF of the H19 DMR. In the OAT group, 16 of 22 patients presented a severe loss of methylation of the 6th CTCF, closely correlated with sperm concentration. The methylation state of DMR0 and of the 3rd CTCF was never affected by the pathological status of sperm samples. This study demonstrates that epigenetic perturbations of the 6th CTCF site of the H19 DMR might be a relevant biomarker for quantitative defects of spermatogenesis in humans. Moreover, we defined a methylation threshold sustaining the classification of patients in two groups, unmethylated and methylated. Using this new classification of patients, the observed intrinsic imprinting defects of spermatozoa appear not to impair significantly the outcome of assisted reproductive technologies.

Abstract
Background Assisted Reproductive Technologies (ART) are increasingly used in humans; however, their impact is now questioned. At blastocyst stage, the trophectoderm is directly in contact with an artificial medium environment, which can impact placental development. This study was designed to carry out an in-depth analysis of the placental transcriptome after ART in mice. Methodology/Principal Findings Blastocysts were transferred either (1) after in vivo fertilization and development (control group) or (2) after in vitro fertilization and embryo culture. Placentas were then analyzed at E10.5. Six percent of transcripts were altered at the two-fold threshold in placentas of manipulated embryos, 2/3 of transcripts being down-regulated. Strikingly, the X-chromosome harbors 11% of altered genes, 2/3 being induced. Imprinted genes were modified similarly to the X. Promoter composition analysis indicates that FOXA transcription factors may be involved in the transcriptional deregulations. Conclusions For the first time, our study shows that in vitro fertilization associated with embryo culture strongly modify the placental expression profile, long after embryo manipulations, meaning that the stress of artificial environment is memorized after implantation. Expression of X and imprinted genes is also greatly modulated probably to adapt to adverse conditions. Our results highlight the importance of studying human placentas from ART.

Abstract
Children conceived through assisted reproductive technologies (ART) now account for a noteworthy proportion (-2.4%) of births in France. Considerable attention is being paid to the outcome of ART pregnancies. The vast majority of these children are apparently normal. However, they are at an increased risk of minor birth defects, low birth weight, and rare imprinting disorders such as Beckwith-Wiedemann syndrome (BWS), Angelman syndrome (AS) and Silver Russel syndrome (SRS). Animal models are important for investigating the possible role of each step of ART (ovarian stimulation, gamete manipulation, in vitro fertilization, embryo culture and embryo transfer) in epigenetic reprogramming This review discusses these issues in the context of epigenetic and developmental abnormalities observed in animals following ART More research is needed on ART-induced errors, focusing not only on genomic imprinting but also on non-imprinted loci, which may help explain some of the more subtle longer-term health effects emerging from studies with animal models.

Abstract
The imprinted H19 gene produces a non-coding RNA of unknown function. Mice lacking H19 show an overgrowth phenotype, due to a cis effect of the H19 locus on the adjacent Igf2 gene. To explore the function of the RNA itself, we produced transgenic mice overexpressing H19. We observed postnatal growth reduction in two independent transgenic lines and detected a decrease of Igf2 expression in embryos. An extensive analysis of several other genes from the newly described imprinted gene network (IGN) was performed in both loss- and gain-of-function animals. We found that H19 deletion leads to the upregulation of several genes of the IGN. This overexpression is restored to the wild-type level by transgenic expression of H19. We therefore propose that the H19 gene participates as a trans regulator in the fine-tuning of this IGN in the mouse embryo. This is the first in vivo evidence of a functional role for the H19 RNA. Our results also bring further experimental evidence for the existence of the IGN and open new perspectives in the comprehension of the role of genomic imprinting in embryonic growth and in human imprinting pathologies.

Abstract
Somatic cell nuclear transfer (SCNT) cloning requires epigenetic reprogramming of a differentiated donor cell nucleus. Incorrect reprogramming of epigenetic marks such as methylation of cytosine (5 mC) is associated with compromised development. Clones that survive into adulthood, in contrast, are assumed to be normal and are expected to be used in global food production. However, the epigenetic status of such healthy adult clones has never been investigated. We used a capillary electrophoresis technique to measure 5 mC content in leukocyte DNA from 38 healthy female clones at 1 to 8 years of age. Fibroblasts from 9 adults were used to generate 2 to 9 clones per donor. Four of the studied clone genotypes were from the Holstein breed, and 5 were from the Simmental breed. Individual 5 mC levels ranged from 4.4 to 6.9% with significant differences in mean 5 mC levels of Holstein and Simmental clones (6.50 ± 0.01% and 5.09 ± 0.02%, P < 0.001). The observed variances in 5 mC between clone genotypes of both breeds were similar (0.0204 and 0.0164), and we computed exact restricted likelihood ratio tests on the basis of linear mixed effects models to test for the presence of variability between genotypes. We found that the estimated variance in 5 mC level within clone genotypes from both breeds (0.104) was higher than the estimated variance between clone genotypes (<10–10). Three Holstein donors were analyzed for the 5 mC level of their genome together with their clones. Two donors exhibited the lowest 5 mC levels of the respective genotypes. The 5 mC level of the third nuclear donor was identical to 1 of its 8 clones, higher than 5 of them, and lower than the 2 remaining ones. This clearly demonstrates that the functional reprogramming of a given donor genotype is compatible with a highly flexible methylation status of its DNA and that genomic copies of adult animals have to be considered as epigenome variants. To quantify the contribution of SCNT to the observed variability between clones, we compared Simmental clones with female Simmental monozygotic twins of similar age that were generated by bisection of fertilized embryos. The estimated variability of 5 mC levels within 5 genotypes of clones (0.0636, n = 19) was clearly higher than in 12 twin pairs (0.0091). In clones, the estimated variability within genotypes (0.0636) was thus higher than between (<10–10) genotypes. In contrast, the variability within twin genotypes (0.0091) was lower than between twin genotypes (0.0136). Absolute deviations of 5 mC values of SCNT clones from their genotype means were 5-fold increased as compared with twins, whereas deviations of genotype means from group means were similar for clones and twins. The comparison with twins confirmed a SCNT cloning effect illustrated by a clone-specific variability of DNA methylation and provided new evidence of DNA hypermethylation by SCNT. Our data show that SCNT cloning can no longer be considered (epi)genetically neutral in apparently healthy adult animals. This raises new scientific and regulatory questions about the risks of disseminating cloned (epi)genetics into animal populations.

Abstract
Until the introduction of Assisted Reproductive Technologies (ART), many studies were conducted in order to evaluate their impact upon the children's health born in such a way. The epigenetic-risk notion was invoked and a link between ART and diseases associated with imprinting alterations was suggested with different examples, such as Beckwith-Wiedemann syndrome (BWS), Angelman syndrome (AS) and Silver-Russell syndrome (SRS). The epigenetic "life cycle" of imprinting (germline erasure, germline establishment, and somatic maintenance) concerns all the phases from gametogenesis, gamete maturation, fertilization, to early embryo development and appears particularly vulnerable to perturbations induced by superovulation, in vitro fertilization, embryo culture and embryo transfer. The studies, performed in model animal, provide a basis of the understanding of imprinting alterations induced by the ART and clinically useful information in order to improve the ART.

Abstract
Intra-uterine growth restriction (IUGR) is a frequent disease, affecting up to 10% of human pregnancies and responsible for increased perinatal morbidity and mortality. Moreover, low birth weight is an important cause of the metabolic syndrome in the adult. Protein depletion during the gestation of rat females has been widely used as a model for human IUGR. By transcriptome analysis of control and protein-deprived rat placentas, we were able to identify 2543 transcripts modified more than 2.5 fold (1347 induced and 1196 repressed). Automatic functional classification enabled us to identify clusters of induced genes affecting chromosome structure, transcription, intracellular transport, protein modifications and apoptosis. In particular, we suggest the existence of a complex balance regulating apoptosis. Among repressed genes, we noted several groups of genes involved in immunity, signalling and degradation of noxious chemicals. These observations suggest that IUGR placentas have a decreased resistance to external aggression. The promoters of the most induced and most repressed genes were contrasted for their composition in putative transcription factor binding sites. There was an over-representation of Zn finger (ZNF) proteins and Pdx1 (pancreatic and duodenal homeobox protein 1) putative binding sites. Consistently, Pdx1 and a high proportion of ZNF genes were induced at the transcriptional level. A similar analysis of ZNF promoters showed an increased presence of putative binding sites for the Tata box binding protein (Tbp). Consistently again, we showed that the Tbp and TBP-associated factors (Tafs) were up-regulated in IUGR placentas. Also, samples of human IUGR and control placentas showed that human orthologous ZNFs and PDX1 were transcriptionally induced, especially in non-vascular IUGR. Immunohistochemistry revealed increased expression of PDX1 in IUGR human placentas. In conclusion, our approach permitted the proposition of hypotheses on a hierarchy of gene inductions/repressions leading to massive transcriptional alterations in the IUGR placenta, in humans and in rodents.

Abstract
BACKGROUND In the last few years, an increase in imprinting anomalies has been reported in children born from Assisted Reproductive Technology (ART). Various clinical and experimental studies also suggest alterations of embryo development after ART. Therefore, there is a need for studying early epigenetic anomalies which could result from ART manipulations, especially on single embryos. In this study, we evaluated the impact of superovulation, in vitro fertilization (IVF) and embryo culture conditions on proper genomic imprinting and blastocyst development in single mouse embryos. In this study, different experimental groups were established to obtain embryos from superovulated and non-superovulated females, either from in vivo or in vitro fertilized oocytes, themselves grown in vitro or not. The embryos were cultured either in M16 medium or in G1.2/G2.2 sequential medium. The methylation status of H19 Imprinting Control Region (ICR) and H19 promoter was assessed, as well as the gene expression level of H19, in individual blastocysts. In parallel, we have evaluated embryo cleavage kinetics and recorded morphological data. RESULTS We show that: 1. The culture medium influences early embryo development with faster cleavage kinetics for culture in G1.2/G2.2 medium compared to M16 medium. 2. Epigenetic alterations of the H19 ICR and H19 PP are influenced by the fertilization method since methylation anomalies were observed only in the in vitro fertilized subgroup, however to different degrees according to the culture medium. 3. Superovulation clearly disrupted H19 gene expression in individual blastocysts. Moreover, when embryos were cultured in vitro after either in vivo or in vitro fertilization, the percentage of blastocysts which expressed H19 was higher in G1.2/G2.2 medium compared to M16. CONCLUSION Compared to previous reports utilizing pools of embryos, our study enables us to emphasize a high individual variability of blastocysts in the H19 ICR and H19 promoter methylation and H19 gene expression, with a striking effect of each manipulation associated to ART practices. Our results suggest that H19 could be used as a sensor of the epigenetic disturbance of the utilized techniques.

Abstract
Preeclampsia is the major pregnancy-induced hypertensive disorder. It modifies the expression profile of placental genes, including several serine protease inhibitors (SERPINs). The objective of this study was to perform a systematic expression analysis of these genes in normal and pathological placentas and to pinpoint epigenetic alterations inside their promoter regions. Expression of 18 placental SERPINs was analyzed by quantitative RT-PCR on placentas from pregnancies complicated by preeclampsia, intrauterine growth restriction, or both and was compared with normal controls. SERPINA3, A5, A8, B2, B5, and B7 presented significant differences in expression in >or=1 pathological situation. In parallel, the methylation status of the CpG islands located in their promoter regions was studied on a sample of control and preeclamptic placentas. Ten SERPIN promoters were either totally methylated or totally unmethylated, whereas SERPINA3, A5, and A8 presented complex methylation profiles. For SERPINA3, the analysis was extended to 81 samples and performed by pyrosequencing. For the SERPINA3 CpG island, the average methylation level was significantly diminished in preeclampsia and growth restriction. The hypomethylated CpGs were situated at putative binding sites for developmental and stress response (hypoxia and inflammation) factors. Our results provide one of the first observations of a specific epigenetic alteration in human placental diseases and provide new potential markers for an early diagnosis.
