We previously reported that exposure to organophosphate (OP) compounds, such as chlorpyrifos (CPF), promotes cardiovascular damage and behavioral alterations in normotensive rats. Also, spontaneously hypertensive rats (SHR), a well-established rodent model of hypertension, exhibit more severe symptoms of acute CPF toxicosis and higher mortality rates, likely due to lower plasma butyrylcholinesterase (BuChE) activity. The potential role of pre-existing hypertension in increasing susceptibility to acute OP toxicity, particularly in relation to psychiatric disorders, remains an open question. Given this, we investigated whether SHR are more susceptible than normotensive Wistar rats to the damage caused by acute CPF exposure on innate (elevated plus maze, EPM; light-dark transition, LDT; and open field tests) and learned (contextual fear conditioning) anxiety-like behaviors. A single dose of CPF (20 mg/kg) induced an anxiolytic-like behavior in SHR exposed to the EPM and no effect in Wistar rats. CPF acute intoxication increased fear expression in both strains, but impaired memory extinction only in Wistar rats. CPF inhibited BuChE in Wistar at all tested doses (10, 20 and 30 mg/kg), whereas inhibition occurred only at the highest dose in SHR. CPF also decreased acetylcholinesterase (AChE) activity in the hippocampus and prefrontal cortex of both strains. In summary, acute intoxication with CPF induces strain-dependent behavioral changes. SHRs intoxicated with CPF may not be the most suitable model for studying anxiety susceptibility to OP intoxication in previously hypertensive rats.</div></div>","PeriodicalId":19144,"journal":{"name":"Neurotoxicology and teratology","volume":"112 ","pages":"Article 107565"},"PeriodicalIF":2.8,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145346303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioral data obtained from control rats within four contract laboratory studies were used to evaluate replicability across studies, calculate the level of statistical power, and estimate the number of animals required for a specific effect size. For the three behaviors evaluated here (motor activity, acoustic startle response, and learning and memory), control rats from all studies showed the expected pattern of behavior, e.g., open field acclimation, startle habituation, % prepulse inhibition (PPI) over pre-pulse intensities, and acquisition and goal quadrant preference in the Morris Water Maze (MWM).

Across all endpoints, a drop in power occurred as differences between two groups became smaller. Power analysis of multiple representative endpoints suggested that a sample size of 20 may detect a 30 % effect with 80 % power. Sample size requirements changed with the effect size, and achieving 80 % power with a 20 % effect size generally required a sample size of 30 rats. While the behavioral performance was replicated over the Study Cohorts, power analyses suggested a need for moderation of expectations regarding detectable differences if decisions relied on single endpoints or small effect sizes.

Accordingly, the aim of this study was to assess the integrated effects of <em>co</em>-exposure to environmentally aged polystyrene microplastics (PS-MPs) and ELTs on behavioral, neuroendocrine, metabolic, and histomorphometric biomarkers in female Swiss mice. To this end, animals were orally exposed to environmentally aged PS-MPs (10 mg/kg/day) and maintained in a climate-controlled chamber at 4 °C for 21 days, whereas control groups were kept at 25 °C. In the behavioral domain, co-exposed animals exhibited increased locomotor disorganization, anxiety-like behavior, reduced exploratory efficiency, and impairments in memory and social discrimination, associated with neuroendocrine alterations involving dopamine, serotonin, epinephrine, and corticosterone, depending on the response evaluated. The retention of PS-MPs in the interscapular brown adipose tissue (iBAT) was confirmed by epifluorescence microscopy. It was associated with oxidative stress, decreased antioxidant defenses, and metabolic dysfunction in iBAT, effects exacerbated by ELT exposure. Multivariate analyses, including principal component analysis (PCA), Random Forest, and structural equation modeling (PLS-PM), revealed distinct phenotypic patterns among groups, as well as integrated causal trajectories linking neuroendocrine dysfunction to systemic phenotypic alterations. In conclusion, our study confirms the initial hypothesis by demonstrating that the combination of ELT and PS-MP ingestion amplifies systemic physiological dysfunctions beyond the effects of each individual stressor, highlighting the vulnerability of homeothermic mammals under multiple environmental pressures, and opening new perspectives for ecotoxicology to consider not only the impacts of global warming, but also the deleterious effects of ELTs in interaction with emerging pollutants.</div></div>","PeriodicalId":19144,"journal":{"name":"Neurotoxicology and teratology","volume":"111 ","pages":"Article 107547"},"PeriodicalIF":2.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144879844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
