Germ cell epigenetic alterations are proposed to mediate these transgenerational defects. Previously, we have shown that prenatal exposure to environmentally relevant doses of BPA or its substitute, BPS, caused transgenerationally maintained reproductive impairments associated with neonatal spermatogonial epigenetic changes in male mice. However, the mechanisms sustaining these changes across generations remain unclear.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;This study aimed to systematically elucidate the mechanism of transgenerational inherence by prenatal BPA and BPS exposure in the murine germline from F1 to F3 generations at both transcriptomic and epigenetic levels.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Pregnant CD-1 females (F0) were orally administered BPA or BPS at doses of 0 (vehicle control), 0.5, 50, or 1000 µg/kg/b.w./day from gestational day 7 to birth. Sperm counts and motility were examined in F1, F2, and F3 adult males. THY1&lt;sup&gt;+&lt;/sup&gt; germ cells on postnatal day 6 from F1, F2, and F3 males at a dose of 50 µg/kg/b.w./day were used for analysis by single-nucleus (sn) multi-omics (paired snRNA-seq and snATAC-seq on the same nucleus).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Prenatal exposure to BPA and BPS with 0.5, 50, and 1000 µg/kg/b.w./day reduced sperm counts in mice across F1 to F3 generations. In the F1 generation, BPA or BPS exposure with 50 µg/kg/b.w./day disrupted the balance between maintaining the undifferentiated and differentiating spermatogonial populations. Differentially accessible peaks (DAPs) by snATAC-seq were primarily located in the promoter regions, with elevated activity of key transcription factors, including SP1, SP4, and DMRT1. Notably, similar gene expression and chromatin changes were observed in directly exposed F1 and F2 generations but differed in the indirectly exposed F3 generation. Approximately 80% of DAPs in F1 and F2 spermatogonia overlapped with histone post-translational modifications linked to transcription activation (e.g., H3K4me1/2/3 and H3K27ac). Across F1 to F3 generations, although BPA exerted more potent effects on gene expression in F1 spermatogonia, BPS induced longer-lasting effects. Interestingly, DMRT1 motif activity was persistently elevated in all three generations following ancestral BPA or BPS exposure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Discussion: &lt;/strong&gt;Our work provides the first systematic analyses of transgenerational gene and chromatin dynamics following prenatal exposure to BPA or BPS. These results suggest that prenatal exposure to environmentally relevant doses of BPA or BPS alters chromatin accessibility and transcription factor motif activities, consequently contributing to disrupted transcriptional levels in neonatal spermatogonia, and some are sustained to F3 generations, ultimately leading to the reduction of sperm counts in adults. https://doi.org/","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":" ","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The zebrafish (<i>Danio rerio</i>) is a powerful vertebrate model that can bridge the gap between <i>in vitro</i> and mammalian-based <i>in vivo</i> studies. However, the behavior-rich repertoire of larval zebrafish, a 3R-compliant model amenable to higher-throughput chemical screens, has yet to be fully deployed to identify and characterize chemical compounds that cause neurotoxicity.</p><p><strong>Objective: </strong>We sought to establish a multi-behavioral phenotyping approach in larval zebrafish to identify and mechanistically elucidate neuroactive chemicals, with particular focus on chemical compounds that affect non-associative habituation learning.</p><p><strong>Methods: </strong>We devised a battery of automated behavior assays in larval zebrafish. The battery captures stereotypical visual and acoustic behaviors including habituation, a form of non-associative learning. To elucidate mechanisms underlying exposure-induced behavioral alterations in zebrafish, <i>in silico</i> target predictions, pharmacological interventions, patch-clamp recordings in cultured mouse cortical neurons, and human multi-neurotransmitter (hMNR) assay in 3D BrainSpheres were used.</p><p><strong>Results: </strong>Known pharmacological modulators of habituation in zebrafish evoked distinct behavioral patterns. By screening chemicals positive for <i>ex vivo</i> N-methyl-D-aspartate receptor (NMDAR) modulation, we identified chlorophene, a biocide that caused sedation, paradoxical excitation, and reduced habituation in zebrafish. Using <i>in silico</i> target predictions and pharmacological interventions, we discovered that chlorophene acts via gamma-aminobutyric acid A receptors (GABA<sub>A</sub>Rs), a previously unknown target site. Orthogonal validation in cultured mouse cortical neurons and human stem cell-derived BrainSpheres confirmed chlorophene's interaction with GABA<sub>A</sub>Rs. Chlorophene's behavioral profile resembled that of flupirtine, a Kv7 potassium channel (M-current) activator, suggesting that habituation deficits stem from M-current rather than GABA<sub>A</sub>R modulation.</p><p><strong>Conclusions: </strong>These studies combined a series of behavior assays in a phenotypically rich, rapid, and inexpensive non-mammalian vertebrate test system to screen chemicals for neurotoxicity. Together with <i>in silico</i> target predictions and mouse- and human-based models, our findings establish multi-behavioral phenotyping in zebrafish as a powerful toolkit for neurotoxicity testing and mechanism identification, with relevance for humans. https://doi.org/10.1289/EHP16568.</p>","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":" ","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144186820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
