However, the detailed toxicological targets and mechanisms by which Cd causes NAFLD are unknown. Therefore, the present work aims to reveal the main targets of action, cellular processes, and molecular pathways by which cadmium causes NAFLD. As shown in the bioinformatics analysis, there were 74 main targets of action for cadmium-induced NAFLD, hemopoietic cell kinase (HCK), EPH receptor A2 (EPHA2), MYC proto-oncogene (MYC), lysyl oxidase (LOX), dipeptidyl peptidase 7 (DPP7), nuclear factor erythroid 2-related factor 2 (NFE2L2), dual specificity phosphatase 6 (DUSP6), CD2 cytoplasmic tail binding protein 2 (CD2BP2), notch receptor 3 (NOTCH3), and phospholipase A2 group IVA (PLA2G4A) were screened as core genes. Testing these core genes in other databases, three differentially expressed genes, HCK, MYC, and DUSP6 were verified and used as targets for drug prediction in DsigDB; decitabine and retinoic acid were screened as potential therapeutic drugs for NAFLD based on the p-value and the combined score. The results of molecular docking showed that the predicted drugs can bind well to the core targets. In conclusion, cadmium is associated with NAFLD; the identified cadmium-toxicity targets, HCK, MYC, and DUSP6, may serve as biomarkers for the diagnosis of NAFLD and predicted drugs, decitabine and retinoic acid may have a potential role in the treatment of NAFLD.","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142978545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to investigate whether CXCL13 regulated the JAK2/STAT3 signaling pathway to participate in cell cycle arrest after mouse spermatogonia cell line (GC-1) exposure to TiO2 NPs. The GC-1 cells were treated with TiO2 NPs at different concentrations (0, 10, 20, 30, and 40 μg/mL) for 24 h to detect cell viability, cell cycle distribution, CXCL13 protein, JAK2/STAT3 pathway-related proteins, and cell cycle-related proteins. The CXCL13 recombinant protein was used to verify the role of CXCL13 in cell cycle and JAK2/STAT3 signaling pathway. TiO2 NPs inhibited cell viability; regulated cell cycle-related proteins including remarkably decreased Cyclin D1, CDK4, Cyclin E1, and CDK2 as well as increased p21; and induced cell cycle arrest at the G0/G1 phase. TiO2 NPs inhibited the levels of CXCL13 protein and weakened the activation of the JAK2/STAT3 signaling pathway by reducing the levels of p-JAK2/JAK2 and p-STAT3/STAT3 proteins. Furthermore, CXCL13 mitigated the suppression of the JAK2/STAT3 signaling pathway and the G0/G1 cell cycle arrest caused by TiO2 NPs. Taken together, TiO2 NPs downregulated the expression of CXCL13 to inhibit the activation of downstream JAK2/STAT3 signaling pathway, eventually inducing cell cycle arrest at the G0/G1 phase. These results provide a novel insight for complemented understanding of the mechanisms of TiO2 NPs-induced cell cycle arrest in GC-1 cells.","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The metabolism of NDMA produces formaldehyde, another alkylating agent and DBP. Both compounds are generated from natural and anthropogenic sources, but the safety restrictions applied to NDMA do not extend to the uses of formaldehyde. Hence, potential health and ecological risks are of concern. Due to limited information on the long-term effects of exposure to these compounds at environmentally relevant concentrations, this work aimed to compare the transgenerational reproductive and developmental toxicity of separate exposures to NDMA or its metabolite formaldehyde in Drosophila melanogaster over four generations. The parental flies were fed NDMA or formaldehyde (1.19E-06 to 5 mM) for 48 h during the third larval instar. Subsequent offspring (F1-F3) were grown under compound-free conditions. In the parental generation, both exposures modified the time to emergence and reduced the number of progenies. NDMA, but not formaldehyde, was lethal, affected fertility, and weakly induced malformations. In the next generations, both exposures induced malformed flies and modified the number of offspring. Reproductive toxicity and malformations were maintained for at least three generations, suggesting that detrimental effects could extend to unexposed offspring. This is the first study reporting the associated individual transgenerational effects on reproduction and development between NDMA and its metabolite formaldehyde in D. melanogaster, highlighting the relevance of evaluating multiple generations to accurately determine the health and environmental risks of pollutants.","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As part of the safety assessment for this particular recombinant humanized type III (RHTypeIII) collagen produced by Komagataella phaffii SMD1168-2COL3, a series of toxicological tests were conducted. This collagen has ≥ 90% amino acid sequence homology to bovine and porcine collagen. The RHTypeIII collagen showed no evidence of genotoxic potential in a battery of tests. It was not toxic in an acute oral study, with no effects at 10 g/kg BW. The RHTypeIII collagen was not developmentally toxic in Sprague Dawley (SD) rat, and the NOAEL was 4.5 g/kg BW/day. In a 90-day oral gavage study in rats, there were no adverse findings observed; therefore, the high dose level (4.5 g/kg BW/day) was considered the NOAEL. The protein sequence was subjected to homology searches against the AllergenOnline database (sliding 80-amino acid windows and full sequence searches). From the 80-amino acid alignment searches, 23 significant matches were identified (> 35% identity and E value < 1 × 10-7) to allergens of bovine, fish, anisakis, feverfew pollen, ragweed pollen, and wheat origin. Although matches were identified, further assessment of the in silico results combined with a literature review demonstrates that the risk of allergenic cross-reactivity for this collagen is low. These results demonstrate RHTypeIII collagen is not toxic and unlikely to present a risk of allergy when used as a food ingredient.","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142921136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was performed to investigate the As-induced inflammatory response and the underlying molecular mechanisms in vitro. Further, the anti-inflammatory effects of a natural dietary polyphenol tannic acid (TA) were also explored. In human normal bronchial (BEAS-2B), adenocarcinoma alveolar basal (A549), and murine macrophages (J774) cell lines, a trivalent form of As (as As3+) exposure markedly induced the expression of various pro-inflammatory mediators (cytokines and chemokines). Additionally, it was found that As3+ exposure induced reactive oxygen species (ROS) generation and activation of the nuclear factor-kappa B (NF-kB) p65 and extracellular signal-regulated kinase (ERK)1/2 pathways in BEAS-2B cells. As expected, the blockade of either ERK1/2 (PD98059) or NF-kB p65 (IMD0354), or both pathways attenuated As3+-induced pro-inflammatory mediators release. Interestingly, pre-treatment with ROS inhibitor N-acetylcysteine (NAC) attenuated activation of ERK/NF-kB pathways, suggesting that ROS have a critical role in pathway's activation and subsequent inflammatory response. Further, TA pre-treatment effectively attenuated As3+-induced inflammatory response by suppressing ROS production and ERK/NF-kB signaling pathways activation. Therefore, this study provides scientific evidence for the anti-inflammatory activities of TA and the underlying molecular mechanisms.","PeriodicalId":15242,"journal":{"name":"Journal of Applied Toxicology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143005773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was designed to evaluate the potential toxicity of oral DHA. DHA was administered orally by gavage to SD rats at doses of 0, 25, 50, and 75/60 mg/kg b.w./day for 28 days, followed by a 4-week recovery period. Concomitant toxicokinetics was also evaluated. Due to potential toxicity affecting survival, only the female top dose was adjusted from 75 to 60 mg/kg on study day 14 (D14). Female rats in the low-dose group and male rats in the low- and medium-dose groups did not show any signs of toxicity. In contrast, male rats in the high-dose group and female rats in the medium- and high-dose groups showed significant toxic effects, including weight loss, hair loss, and gastrointestinal reactions (soft stools, perianal dirt, and fecal abnormalities). At the end of administration, female rats in the 75/60 (dose-adjusted) mg/kg dose group had significantly higher reticulocytes (Ret% and RETIC) and alanine aminotransferase (ALT), increased liver weights, and significantly lower hemoglobin (HGB). In addition, histopathology showed mild vacuolation of hepatocytes. These findings suggest that female rats have a greater toxic response than males, and toxicokinetics further demonstrate this sex difference. However, the toxic effects of DHA were reversed at the end of the 4-week recovery period. Therefore, the liver was identified as the primary target organ.
