The observed potencies showed no correlation with polycyclic aromatic hydrocarbons (PAHs) content and the observed lung cancer risks of the coal samples.

We aimed to evaluate the hepatic and renal effects of subchronic low‐dose oral exposure to HCB, DDT, and p,p′‐DDE in male rats using serum biochemistry and histopathology. Thirty‐two male Sprague–Dawley rats were randomly assigned to control, HCB, DDT, and p,p′‐DDE groups ( n  = 8/group).

Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin, blood urea nitrogen (BUN), and creatinine were measured. Liver and kidney tissues were examined histologically and injury was quantified by a semi‐quantitative histopathological H‐score. Exposure did not significantly alter ALT, AST, total bilirubin, BUN or creatinine. However, ALP activity was significantly decreased in the DDT‐ and p,p′‐DDE‐treated groups ( p  &lt; 0.05).

Hepatic architecture and H‐score were similar in all groups. Low‐dose subchronic exposure to HCB and DDT was associated with quantifiable renal histopathological alterations in the absence of parallel biochemical abnormalities, which may reflect early, subclinical nephrotoxicity.

In the present study, the antibacterial, antibiofilm, toxicological, histopathological, and immunomodulatory effects of Rhizophora apiculata leaf extract were investigated against Aeromonas hydrophila using zebrafish ( Danio rerio ) as a vertebrate model. The methanolic leaf extract was characterized by FTIR and GC–MS analyses, which indicated the presence of diverse functional groups and putatively identified metabolites belonging to several chemical classes. The extract exhibited antibacterial activity against A. hydrophila , with a minimum inhibitory concentration (MIC) of 125 μg/mL, compared with 15.6 μg/mL for ampicillin. Quantitative crystal violet and confocal microscopy analyses demonstrated concentration‐ and time‐dependent inhibition and disruption of established biofilms, with the greatest effect observed at 500 μg/mL after 48 h. Acute toxicity assessment revealed concentration‐dependent mortality, with 96‐h LC 50 values of 375 μg/mL for embryos and larvae and 200.5 μg/mL for adults, indicating greater sensitivity of adult fish. In A. hydrophila ‐challenged zebrafish, treatment with the extract reduced infection‐associated gill and muscle alterations and improved the observed developmental morphology. The treatment was also associated with differential expression of IL‐8 , TNF‐α , and TGF‐β , indicating modulation of immune‐related transcriptional responses. However, the treatment concentration of 250 μg/mL exceeded the estimated adult LC 50 , limiting interpretation of these protective responses as evidence of a safe therapeutic dose.

While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized. In this study, we employed a transcriptomic approach to investigate the transcriptional responses of Drosophila melanogaster following exposure to acrylamide (100 mg/kg). Our analysis identified 634 differentially expressed genes (DEGs), with 362 upregulated and 272 downregulated. Functional analysis revealed these DEGs are enriched in pathways related to reproduction, detoxification, cellular and metabolic processes, signaling, synaptic formation and organization. Notably, acrylamide exposure upregulated the expression of tau and beta-amyloid protein precursor-like genes, both implicated in Alzheimer's disease pathology. An aversive memory test further demonstrated that acrylamide impaired the short-term memory of treated flies. Additionally, acrylamide-induced toxicity altered the expression of nine long terminal repeat retrotransposons, belonging to the gypsy and pao superfamilies. By exploring the potential role of transposable element activity in acrylamide-mediated toxicity, this study provides novel insights into the molecular mechanisms underlying its effects. Collectively, these findings offer a more comprehensive understanding of the mechanisms and pathways associated with the toxic action and detoxification of acrylamide in D. melanogaster.</p>","PeriodicalId":11756,"journal":{"name":"Environmental Toxicology","volume":" ","pages":"1105-1118"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13537343/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147270125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research focused on key biomarkers of oxidative stress (MDA), inflammation (myeloperoxidase activity, nitrite production), and immune function (TNFα and IL-6 cytokine production, both at baseline and following LPS stimulation). Results indicated species-specific differences in oxidative stress response, with sheep and goats showing higher MDA levels under combined PFOS and GLY exposure. Furthermore, co-exposure exacerbated inflammatory responses (MDA activity and NO2- production) in LPS-stimulated sheep and goats. Critically, a synergistic effect of PFOS and GLY co-exposure significantly increased both TNFα and IL-6 production across all species, even without LPS stimulation, suggesting a heightened pro-inflammatory state. These findings raise concerns about the potential of these contaminants to disrupt immune homeostasis in grazing animals, impacting their health, productivity, and disease resistance, and potentially posing risks to human health through food chain contamination. The study highlights the need for further research to elucidate the underlying molecular mechanisms and assess the long-term effects of chronic exposure to these contaminants on animal health and potential human health risks.</p>","PeriodicalId":11756,"journal":{"name":"Environmental Toxicology","volume":" ","pages":"1097-1104"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13537357/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147270111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
