The adverse outcome pathway (AOP) has been conceptualized in 2010 as an analytical construct to describe a sequential chain of causal links between key events, from a molecular initiating event leading to an adverse outcome (AO), considering several levels of biological organization. An AOP aims to identify and organize available knowledge about toxic effects of chemicals and drugs, either in ecotoxicology or toxicology, and it can be helpful in both basic and applied research and serve as a decision-making tool in support of regulatory risk assessment. The AOP concept has evolved since its introduction, and recent research in toxicology, based on integrative systems biology and artificial intelligence, gave it a new dimension. This innovative in silico strategy can help to decipher mechanisms of action and AOP and offers new perspectives in AOP development. However, to date, this strategy has not yet been applied to ecotoxicology. In this context, the main objective of this short article is to discuss the relevance and feasibility of transferring this strategy to ecotoxicology. One of the challenges to be discussed is the level of organisation that is relevant to address for the AO (population/community). This strategy also offers many advantages that could be fruitful in ecotoxicology and overcome the lack of time, such as the rapid identification of data available at a time t, or the identification of "data gaps". Finally, this article proposes a step forward with suggested priority topics in ecotoxicology that could benefit from this strategy. [ABSTRACT FROM AUTHOR]

[SDE.ES]Environmental Sciences/Environmental and Society - Abstract
International audience; The objectives of environmental health research are diverse (e.g.: identifying situations at potential risk, estimating exposures and effects, testing the effectiveness of preventive actions) and related methods are diverse as well. Opportunities for greater implication of the civil society and related challenges differ at each step of research activities. These aspects need to be better known and shared collectively.

International audience; Context: Participatory research in environmental health remains rare in France. The objectives of environmental health research projects can, like their methods, be very diverse. Opportunities for greater involvement of civil society, as well as its challenges, differ at each step of such research activities. All these aspects need to be widely shared. As a preparatory step toward the development of concrete new participatory research projects on multiple environmental exposures, the LILAS project aimed to (1) favor the mutual understanding of the main issues and research methods in environmental health and their stakes for different participants, but also the requirements, strengths, and limitations of these methods, and (2) identify the expected benefits and points to watch out for related to stronger civic participation in these projects.Methods: The LILAS project identified and gathered together institutional researchers, academics and civil society participants (mainly from nongovernmental organizations) interested in multiple exposures (chemical and radiological). The relevant literature was searched to learn from previous participatory research projects in this broad field. Several meetings enabled the group to collectively identify different types of studies and analyze the benefits, limitations and methods related to the introduction of such participation. An analysis matrix was co-constructed and completed by study participants, as in a Living Lab approach.Results: The matrix lists for different types of studies (assessment of environmental exposures, identification of their determinants, interventions on these exposures, quantitative risk assessment, epidemiological studies, experimental research, ecosystem health, etc.) the expected benefits for several categories of stakeholders, the fundamental principles of research methods, and their related practical constraints, advantages and limitations related to the use of participatory or more standard approaches.Conclusion: The LILAS project enabled the development of a solid basis for the co-construction of participatory research projects to study multiple environmental exposures.; Contexte : Les recherches participatives en santé-environnement restent encore peu développées en France. Les objectifs poursuivis par les recherches en santé-environnement (par exemple : estimer des expositions et/ou des effets, tester des actions préventives) et les méthodes employées à ces fins sont variées. Les opportunités d’une plus grande implication de la société civile et les défis associés diffèrent à chaque étape de ces recherches. Ces aspects demandent à être mieux appréhendés collectivement. Le projet LILAS visait, en amont du développement de futurs projets concrets de recherches participatives sur les multi-expositions environnementales, à (1) favoriser une bonne compréhension commune des principales problématiques et méthodes de recherche en santé-environnement, de leurs enjeux, prérequis, forces et limites, et à (2) identifier les bénéfices et points de vigilance liés à l’introduction de plus fortes dimensions participatives dans ces recherches.Méthode adoptée : Le projet LILAS a identifié et rassemblé des chercheurs institutionnels, académiques et acteurs de la société civile (associations loi 1901) intéressés par les multi-expositions (chimiques, radiologiques). Cinq réunions ont permis d’identifier collectivement différents types d’études et de réfléchir sur les apports, limites et prérequis méthodologiques relatifs à l’introduction de différents degrés de participation dans celles-ci. Une matrice résumant ces aspects a été co-construite puis alimentée par les participants, en s’inspirant des approches Living Lab (soit laboratoire vivant).Résultats : Pour différents types d’études (études d’estimations d’expositions, d’interventions sur celles-ci, évaluations de risques sanitaires, études épidémiologiques, expérimentales, études sur la santé des écosystèmes, etc.), la matrice élaborée en commun liste les bénéfices attendus pour différentes parties prenantes, les principes fondamentaux des méthodes employées et contraintes pratiques associées, les avantages et limites relatifs à l’emploi d’approches participatives (notamment les Living Labs) ou plus « classiques ».Conclusion : Le projet LILAS a permis de poser des bases consolidées pour la co-construction de projets de recherches participatives sur les multi-expositions environnementales.

[SDV.SPEE]Life Sciences [q-bio]/Santé publique et épidémiologie - Abstract
International audience; ContextThe whole population is exposed throughout its life to ionizing radiation (IR) at varying levels, via multiple natural and artificial sources, whether in the context of the residential environment, various activities (professional or other such as air travel) or for medical reasons (diagnostic or therapeutic procedures). The carcinogenic effects of IR are well documented at dose levels of 100 milliGrays (mGy) or higher. There is still controversy about the shape of the relationships between exposure and cancer risks at lower doses, called “low doses”. In addition, quantification of the effects of multi-exposure to IR and other cancer risk factors is poorly documented, with the exception of the interaction between tobacco and radon on lung cancer risk. Similarly, the relationships between exposures to IR at different stages of life (e.g., during childhood, puberty, etc.) and late health effects remain poorly characterized. Potential associations between low doses of IR and non-cancer chronic diseases also require better documentation. ObjectivesThe first objective of the CORALE project is to carry out the broadest possible reconstruction of doses of IR from environmental sources (radon, terrestrial and cosmic radiation, food, nuclear installations and other artificial sources), medical (diagnostic and therapeutic procedures) and occupational (nuclear workers but also other industries using radioactive sources, health professionals… ) received by participants in the Constances cohort since birth, following the logic of the exposome concept (for its radiological component). The second objective will be to estimate the risks of cancers and other chronic diseases potentially associated with the cumulative doses received (from several sources of IR and over time) taking into account the potential influence of the context of multi-exposures to other risk factors.MethodsIn order to reconstruct the annual doses due to radioactivity of natural and artificial origin received by each member of the Constances cohort since their birth, a large number of sources of radioactivity must be considered. Reconstructions related to environmental, medical and occupational exposures will be performed by different units of the IRSN in collaboration with the Constances cohort team. To do this, a questionnaire will be sent to cohort members who have already provided their residential histories. The statistical analyses (e.g., Cox models with time-dependent covariates) will be carried out at the IRSN epidemiology laboratory and will benefit from the expertise of radiobiologists, supporting the exploration of specific hypotheses and interpretations. The use of innovative regression methods on exposure profiles will be explored in collaboration with the University of Paris.PerspectivesCORALE is part of a broader long-term research programme, which will include the effects of other multi-exposures (e.g., IR and other environmental exposures) and the study of risk and exposure biomarkers through the Constances biobank, further complementing the application of the exposome concept through the study of within-body regulations following exposures. This program will help improve the characterization of the exposome and its relation with chronic diseases in the Constances cohort.

[SDV]Life Sciences [q-bio] - Abstract
International audience; Embryonic development is particularly vulnerable to stress and DNA damage, as mutations can accumulate through cell proliferation in a wide number of cells and organs. However, the biological effects of chronic exposure to ionising radiation (IR) at low and moderate dose rates (< 6 mGy/h) remain largely controversial, raising concerns for environmental protection. We employed a systems biology approach involving, transcriptomics and epigenetics to understand how exposures to low to moderate dose rates of IR impact embryonic development, using zebrafish as a model. Our data highlight that the transcriptional program regulating morphogenesis in gastrulating embryos was modified at dose rates greater than or equal to 0.5 mGy/h, which might predict potential neurogenesis and somitogenesis defects observed at similar dose rates later in development. In particular we observed that the retinoic acid pathway was impaired during gastrulation and after organogenesis, and might thus constitute a key event in the progression of the adverse outcomes induced by RI. Future studies will employ functional studies to better characterize the implication of the retinoic acid pathway.

Embryonic development is particularly vulnerable to stress and DNA damage, as mutations can accumulate through cell proliferation in a wide number of cells and organs. However, the biological effects of chronic exposure to ionising radiation (IR) at low and moderate dose rates (<, 6 mGy/h) remain largely controversial, raising concerns for environmental protection. The present study focuses on the molecular effects of IR (0.005 to 50 mGy/h) on zebrafish embryos at the gastrula stage (6 hpf), at both the transcriptomics and epigenetics levels. Our results show that exposure to IR modifies the expression of genes involved in mitochondrial activity from 0.5 to 50 mGy/h. In addition, important developmental pathways, namely, the Notch, retinoic acid, BMP and Wnt signalling pathways, were altered at 5 and 50 mGy/h. Transcriptional changes of genes involved in the morphogenesis of the ectoderm and mesoderm were detected at all dose rates, but were prominent from 0.5 to 50 mGy/h. At the epigenetic level, exposure to IR induced a hypomethylation of DNA in the promoter of genes that colocalised with both H3K27me3 and H3Kme4 histone marks and correlated with changes in transcriptional activity. Finally, pathway enrichment analysis demonstrated that the DNA methylation changes occurred in the promoter of important developmental genes, including morphogenesis of the ectoderm and mesoderm. Together, these results show that the transcriptional program regulating morphogenesis in gastrulating embryos was modified at dose rates greater than or equal to 0.5 mGy/h, which might predict potential neurogenesis and somitogenesis defects observed at similar dose rates later in development.

International audience; contamination of the environment after the chernobyl and fukushima Daiichi nuclear power plant (npp) disasters led to the exposure of a large number of humans and wild animals to radioactive substances. However, the sub-lethal consequences induced by these absorbed radiological doses remain understudied and the long-term biological impacts largely unknown. We assessed the biological effects of chronic exposure to ionizing radiation (IR) on embryonic development by exposing zebrafish embryo from fertilization and up to 120 hours post-fertilization (hpf) at dose rates of 0.5 mGy/h, 5 mGy/h and 50 mGy/h, thereby encompassing the field of low dose rates defined at 6 mGy/h. Chronic exposure to IR altered larval behaviour in a light-dark locomotor test and affected cardiac activity at a dose rate as low as 0.5 mGy/h. The multi-omics analysis of transcriptome, proteome and transcription factor binding sites in the promoters of the deregulated genes, collectively points towards perturbations of neurogenesis, muscle development, and retinoic acid (RA) signaling after chronic exposure to iR. Whole-mount RnA in situ hybridization confirmed the impaired expression of the transcription factors her4.4 in the central nervous system and myogenin in the developing muscles of exposed embryos. At the organ level, the assessment of muscle histology by transmission electron microscopy (TEM) demonstrated myofibers disruption and altered neuromuscular junctions in exposed larvae at 5 mGy/h and 50 mGy/h. The integration of these multi-level data demonstrates that chronic exposure to low dose rates of iR has an impact on neuronal and muscle progenitor cells, that could lead to motility defects in free swimming larvae at 120 hpf. The mechanistic understanding of these effects allows us to propose a model where deregulation of RA signaling by chronic exposure to IR has pleiotropic effects on neurogenesis and muscle development.

[SDV]Life Sciences [q-bio] - Abstract
International audience; After the nuclear accidents at Chernobyl and Fukushima and due to a growing use of radionuclides, radiation protection of the environment is a major concern. Studies show an increased sensitivity to ionizing radiation (IR) during development. However, there are few data on the molecular mechanisms leading to the effects of IR on embryogenesis and moreover for chronic exposures. In this context, the objective of this thesis is to better understand the effects of exposure to IR on the development of zebrafish (Danio rerio), a model organism in ecotoxicology and in biomedicine. Fertilized eggs were exposed to gamma rays emitted by a 137Cs source at low to moderate dose rates (from 0.005 mGy/h to 50 mGy/h), then analysed from the gastrula stage (6 hours) to the larval stage (5 days) by an integrative approach from molecular effects to behavioural effects. Part of this work has focused on studying the effects of IR at an early stage of zebrafish development after exposure to IR. For this, a multi-omics approach with the study of the transcriptome and the methylome has been implemented. A transcriptomic study at the shield stage with dose rates ranging from 0.005 mGy/h to 50 mGy/h was carried out and demonstrated a moderate but significant effect on the regulation of oxidative stress and mitochondrial activity. At 5 and 50 mGy/h, the genes involved in the development of the central nervous system (CNS) and muscles are affected. The methylome study has revealed hypomethylation of the promoter sequences of genes involved in the development of the CNS and muscles, associated with a modification of gene expression. These results on early embryonic stages, highlight potential effects on the development of the CNS and muscles. The other part of this work focused on assessing the effects of IR exposure at later developmental stages using a system biology approach. For this, analyses were carried out from the molecular scale to the phenotypic scale. At the molecular level, a multi-omics analysis of the transcriptome and the proteome has highlighted the modulation of genes involved in the retinoic acid pathway, the development of the CNS and muscles in embryos and larvae exposed to 0.5; 5 and 50 mGy/h. Labelling by in-situ hybridization confirmed the misregulation of the transcription factors her4.4 in the CNS and myog in the muscles of embryos exposed to IR. At the tissue level, disruption of muscle myofibrils and alteration of neuromuscular junctions are detected in embryos exposed to 5 and 50 mGy/h. In order to assess an individual effect at phenotypic scale, the locomotor behaviour of the larvae was assessed under stress conditions. A significant decrease in larval motility was detected between 0.5 mGy/h and 50 mGy/h. This work has shown effects of IR on the development of the CNS and muscles from early development at the molecular level. These effects are confirmed at later stages of development. This study suggests that the molecular disturbances observed during early development are predictive of the effects observed at later developmental stages. In addition, this thesis work allows us to propose a model of "Adverse Outcome Pathway" where the deregulation of the retinoic acid pathway by exposure to IR will lead to effects on the development of the CNS and muscles.

[SDE]Environmental Sciences - Abstract
International audience; In order to predict long term consequences of pollution on wildlife, toxic effects have to be assessed on a multigenerational scale. DEBtox models were recently developped to analyze effects of alpha and gamma radiation over several generations of Daphnia magna. A transgenerational damage compartement which level is transmitted from parent to offspring, was used to account for changes in effect severity observed among generations. However, the nature of molecular mechanisms involved in the transmission of radio-induced damage accross generations are poorly understood. In this context, the role of epigenetic processes was recently investigated in D. magna, as part of the transgenerational response to external Cs-137 gamma irradiation (at dose rates of 6.5 µGy/h and 41.3 mGy/h). In this aim, we studied DNA methylation changes after a 25-day chronic exposure of a parental generation (F0) and their potential inheritance by subsequent recovering generations, including F2 (exposed as germ cells in F1 embryos) and F3 (the first truly unexposed generation). Effects on survival, growth and reproduction were examined in all generations and DNA was extracted for whole genome bisulfite sequencing. Results showed that effects on reproduction were significant in generation F0 at the high dose rate and absent in subsequent generations (F1, F2 and F3). In contrast, we detected significant DNA methylation changes in every generation independent of dose rate. Some of these changes were shared between dose rates and among generations. Involved genes included gene families and gene functions which were previously shown to play roles during exposure to ionising radiation. Common DNA methylation changes detected between generations F2 and F3 clearly showed that epigenetic modifications were transmitted to unexposed generations, most likely through the germline.
