Abstract
Thyroid hormone system disrupting compounds are considered potential threats for human and environmental health. Multiple adverse outcome pathways (AOPs) for thyroid hormone system disruption (THSD) are being developed in different taxa. Combining these AOPs results in a cross-species AOP network for THSD which may provide an evidence-based foundation for extrapolating THSD data across vertebrate species and bridging the gap between human and environmental health. This review aimed to advance the description of the taxonomic domain of applicability (tDOA) in the network to improve its utility for cross-species extrapolation. We focused on the molecular initiating events (MIEs) and adverse outcomes (AOs) and evaluated both their plausible domain of applicability (taxa they are likely applicable to) and empirical domain of applicability (where evidence for applicability to various taxa exists) in a THSD context. The evaluation showed that all MIEs in the AOP network are applicable to mammals. With some exceptions, there was evidence of structural conservation across vertebrate taxa and especially for fish and amphibians, and to a lesser extent for birds, empirical evidence was found. Current evidence supports the applicability of impaired neurodevelopment, neurosensory development (eg, vision) and reproduction across vertebrate taxa. The results of this tDOA evaluation are summarized in a conceptual AOP network that helps prioritize (parts of) AOPs for a more detailed evaluation. In conclusion, this review advances the tDOA description of an existing THSD AOP network and serves as a catalog summarizing plausible and empirical evidence on which future cross-species AOP development and tDOA assessment could build.

Abstract
Congenital hypothyroidism (CH) is a highly prevalent but treatable neonatal endocrine disorder. Thyroid dyshormonogenesis is the main cause of congenital hypothyroidism in Chinese CH patients, and DUOX2 is the most frequent mutated gene involved in H2O2 production. In humans, the primary sources for H2O2 production are DUOX1 and DUOX2, while in zebrafish there is only a single orthologue for DUOX1 and DUOX2. In this study, duox mutant zebrafish were generated through knockdown duox by morpholino or knockout duox by CRISPR Cas9. The associated phenotypes were investigated and rescued by thyroxine (T4) treatment. Mutant zebrafish displayed hypothyroid phenotypes including growth retardation, goiter and, infertility. Homozygous mutants in adults also displayed extrathyroidal abnormal phenotypes, including lacking barbels, pigmentation defects, erythema in the opercular region, ragged fins, and delayed scales. All these abnormal phenotypes can be rescued by 10 nM T4 treatment. Strikingly, the fertility of zebrafish was dependent on thyroid hormone; T4 treatment should be continued and cannot be stopped over 2 weeks in hypothyroid zebrafish in order to achieve fertility. Thyroid hormones played a role in the developing and maturing of reproductive cells. Our work indicated that duox mutant zebrafish may provide a model for human congenital hypothyroidism.
