Esketamine (ESK), a new psychoactive substance known for its strong hallucinogenic effect, has been detected in surface water worldwide. The toxicity of ESK to fish at certain environmental concentration remains unclear. In this study, zebrafish embryos and ZF4 cells were exposed (0, 0.12, 1.02, 10.6 μg L-1, marked by SC, LC, MC, HC, respectively) 14 days post fertilization (dpf) 24 h, respectively. Biphasic dose responses induced observed after h exposure. ESK-LC ESK-MC obviously increased embryo area length, height, volume yolk sac, whereas ESK-HC had the opposite effect. appreciably upregulated transcription expression levels vtg, disrupting cell cycle After dpf exposure, KEGG analysis indicated that circadian rhythm, nucleotide excision repair, estrogen signaling pathways top three impacted pathways, with significantly enhancing gene these except cyp7a1 bh1he41. Correspondingly, notably VTG level, aligning relatively high affinity receptors, as analyzed through molecular docking. Our research demonstrated exhibits developmental endocrine-disrupting effects zebrafish, highlighting need address ecological fish.
