While previous research focused on its insecticidal properties and sodium-channel-targeting toxins, its venom remains largely unexplored using modern proteomic approaches. We analyzed the venom composition of H. judaicus from Lebanese specimens using nESI-MS/MS, MALDI-TOF MS, SDS-PAGE, and RP-HPLC. Venom lethality in mice was assessed (LD₅₀ = 11.87 [6.59-17.16] mg/kg, i.p.), confirming moderate toxicity to vertebrates. RP-HPLC on C<sub>18</sub> resolved 37 peaks, with 25 eluting between 20-40% acetonitrile. Reducing SDS-PAGE revealed predominant components < 10 kDa and minor bands at 31, 46, and 77 kDa. MaLDI-TOF MS detected 20 components from 1,000-12,000 m/z. A bottom-up shotgun nLC-MS/MS approach, following in-gel tryptic digestion of venom, identified 55 components across 15 protein families. Ion channel-active toxins [K⁺ (7), Na⁺ (16), Cl⁻ (1), ryanodine receptor (1)] and enzyme components (17) were predominant. This study provides proteomic evidence of H. judaicus venom components previously only identified at the transcriptomic level and reveals a richer venom profile than anticipated. Novel identified components include alternative β-subunits of lipolysis-activating proteins, as well as homologs of Olivierus martensii antimicrobial peptide inhibitor HAP-1, Leiurus hebraeus Lqhβ1, Parabuthus transvaalicus Birtoxin, and peptide Hj2a from Hottentotta jayakari exhibiting dual α/β-toxin activity on Nav1.1 channels.

We do so by analysing and interpreting a very large qualitative data set of experts' observations, collected in a 3-day interactive workshop and three follow-up online workshops with a heterogeneous sample of experts representing major actors from the global regulatory toxicology system. We identified leverage points (where a small change within a system can have a disproportionately large effect) in the six core aspects-infrastructure, processes, culture, technology, goals, and actors-in the regulatory toxicology system to facilitate the effective use of NAMs. Identified systematic leverage points include the need for a functioning incentive structure for effectively discovering, developing, validating and using NAMs within academia, regulation, and industry; and measures that prevent or mitigate unwanted effects of using NAMs that acknowledge clashes between scientific, regulatory, political and social processes.

Glyphosate exposure led to alterations in plasma cytokine levels, including marked increases in IL-4 and IL-5, a modest rise in IFN-γ, and a decrease in IL-8. No changes in plasma IL-12/23p40, IL17 and IL-33 were found. The IFN-γ/IL-4 ratio decreased, accompanied by changes in T cell subpopulations.

Since the shikimate pathway, targeted by glyphosate, is also present in Gram-negative bacteria. Overall, these findings suggest that glyphosate can affect the immune system, favoring Th2 responses.

This state is known as oxidative eustress. Key redox signaling molecules, such as superoxide anion radical (O&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;•-&lt;/sup&gt;) and hydrogen peroxide (H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;), operate at nanomolar concentrations and are produced by NADPH oxidases (regulated by various factors), the mitochondrial electron transport chain (ETC), and numerous enzymes. In addition, cell signaling is influenced by nitric oxide (NO&lt;sup&gt;•&lt;/sup&gt;) and reactive lipid species. Disruption of ROS signaling can lead to oxidative stress, a harmful condition associated with many chronic diseases, including cancer. The dual nature of ROS is evident in premalignant and malignant cells at all stages of tumor development, including proliferation, migration/invasion, angiogenesis, inflammation, immune evasion, and metastasis. ROS can promote tumor formation by regulating immune cells, mitochondrial metabolism, DNA methylation, DNA damage [such as the DNA oxidation product, 8-oxo-dG, resulting from hydroxyl radical (&lt;sup&gt;•&lt;/sup&gt;OH) attack], and other mechanisms. The tumor-promoting activity mediated by H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; manifests through the promotion of epithelial-to-mesenchymal transition (EMT) and the formation of the tumor microenvironment (TME) by tumor-associated macrophages. While ROS are vital for tumor initiation and growth, their excessive production can also have anticancer effects by inducing senescence, apoptosis, or necrosis. ROS-related anticancer mechanisms include mitochondrial dysfunction, p53-dependent apoptosis, iron-dependent ferroptosis, activation of endoplasmic reticulum stress, inhibition of growth signaling pathways (such as the epidermal growth factor pathway, EGF), among others. Tumor cells employ a range of adaptive mechanisms to effectively maintain ROS levels within a dynamic range that promotes proliferation while preventing cell death. This regulation is achieved by fine-tuning the effects of antioxidants throughout all stages of cancer. During early tumor development, characterized by increased oncogene-induced oxidative stress, cancer cells depend on glutathione (GSH) and upregulated antioxidant gene expression controlled by nuclear factor erythroid 2-related factor 2 (NRF2) to maintain redox balance. The opposing roles of certain antioxidant enzymes, such as Mn-SOD (SOD2), illustrate the same duality as ROS, acting as potential tumor suppressors during early carcinogenesis and as tumor promoters during metastasis. Low-molecular-weight antioxidants such as vitamins C (ascorbate) and E (tocopherols), carotenoids (e.g., lycopene, β-carotene), flavonoids (e.g., quercetin), and isoflavones demonstrate effective antioxidant activity in vitro, but their anticancer effects in clinical settings remain unproven.

Despite their established status as such, the association between maternal exposure to PAEs during pregnancy and the levels of maternal thyroid hormones remains a subject of considerable debate. To shed light on this contentious issue, we conducted an investigation involving 1,156 pregnant women from the Zunyi birth cohort. The aim was to elucidate the relationship between urinary metabolites of PAEs and serum thyroid hormones during the gestational period. In this study, we employed a linear mixed-effects model (LMM) to assess the correlation between PAE metabolites and thyroid hormones. Additionally, restricted cubic spline (RCS) analysis was utilized to explore the dose-response relationship between these PAE metabolites and thyroid hormones. Furthermore, Bayesian kernel machine regression (BKMR) was applied to determine the potential overall effects and to uncover any non-linear relationships that might exist. Our results revealed that several PAE metabolites, namely, monomethyl phthalate (MMP), mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-carboxypentyl) phthalate (MECPP), mono-isobutyl phthalate (MIBP), mono(2-ethyl-5-oxohexyl) phthalate (MOP), and monobenzyl phthalate (MBZP), were associated with correlations involving total thyroxine (TT4), free triiodothyronine (FT3), and free thyroxine (FT4). Subsequently, the restricted cubic spline (RCS) analyses demonstrated a clear dose-response relationship between the PAE metabolites and maternal thyroid hormones, with MEHP, MBZP, MIBP, and MBZP emerging as the major contributors to this relationship. Finally, the BKMR model indicated a non-linear relationship, specifically an inverted U-shaped relationship, between maternal exposure to PAEs during pregnancy and the levels of TT4, FT3, and FT4. Collectively, our findings strongly suggest that exposure to PAEs during pregnancy has a detrimental impact on the secretion of maternal thyroid hormones.

While NAMs offer human-relevant, efficient alternatives for chemical safety evaluation, critical bottlenecks remain. These involve insufficient physiological complexity in current in vitro models, interpretability limitations of AI-driven approaches, challenges in quantifying mixture toxicity and low-dose effects, and a lag in regulatory adoption. Emerging strategies like probabilistic risk assessment, AI-driven exposomics, and tiered testing paradigms hold promise for addressing chemical mixture risks and personalized exposures. Future progress requires interdisciplinary collaboration to refine microphysiological systems, harmonize regulatory frameworks with scientific innovation, and establish open-access data repositories, paving the way for precision toxicology and sustainable chemical risk management.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":6.9,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144940399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
