The excessive generation of oxidative stress is observed in CKDu patients in many experiments. Agrochemicals are identified as a major inducer of oxidative stress. Oxidative stress is induced mainly by direct generation of ROS through enzyme activation and by depleting antioxidant enzymes. To study how toxic exposure to agrochemicals alters the oxidative stress level in CKDu, a mathematical model of the body’s Redox system was developed and simulated how toxic exposure to agrochemicals, particularly arsenic toxicity, increases oxidative stress in cells. This model was employed to study how the molecular mechanisms of ROS generation are affected in CKDu. The study explores how arsenic concentration levels alter the oxidative stress levels and molecular interactions involved. The model indicates that the mitochondrial electron transport chain complex III is the primary contributor to ROS production, which needs to be validated through wet lab experiments. Sensitivity analyses on the model revealed that parameters associated with superoxide production are susceptible to perturbations. Further analysis shows that enzyme-driven reactions, especially those involving superoxide generation, catalase, and glutathione peroxidase, are crucial in governing oxidative stress generation in CKDu.

Acetaminophen (APAP) is a common antipyretic, but its overdose is a leading cause of acute liver failure. Clinical studies suggest that APAP-induced hepatotoxicity can be more frequent and severe in obese patients with MASLD. To investigate this process, we have developed a new mathematical model that comprehensively incorporates lipid metabolism, APAP metabolism, and glutathione (GSH) detoxification. In MASLD patients, we found that CYP and GST activities have higher sensitivity to ROS production than UGT and SULT, which are highly effective in detoxifying APAP. We also highlighted that the upregulation of GPx poses an unanticipated risk during steatosis by inducing an increase in H<sub>2</sub>O<sub>2</sub>. This occurs due to a vicious circle in which increasing NAPQI adducts further elevate H<sub>2</sub>O<sub>2</sub> levels. According to clinical reports, the toxicity of APAP varies depending on the progression of MASLD. We simulated that the pool of enzymatic alterations observed in steatotic patients exacerbates APAP-induced toxicity, which is thought to be due to a significant upregulation of CYP2E1. In contrast, the enzyme changes in MASH patients alleviate APAP-induced toxicity, likely due to decreased activity of CYPs and increased activity of UGT and GST. We believe that our strategy, which couples lipid and drug metabolism, offers valuable pharmacological insights for identifying enzymes that play a significant role in liver injury and for devising future therapeutic strategies in the context of MASLD.</div></div>","PeriodicalId":37651,"journal":{"name":"Computational Toxicology","volume":"36 ","pages":"Article 100384"},"PeriodicalIF":2.9,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145269225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that QPCA-KNN achieves the highest accuracy at 99.05%, outperforming other methods across all performance metrics and demonstrating superior classification capability. RBF (96.24%) and ELM (95.81%) also exhibit strong performance, though slightly lower than QPCA-KNN, while DT (92.35%) shows the lowest accuracy but still maintains reasonable performance.

A common theme across these overarching decision contexts is the need for assembling and integrating human health relevant data such as toxicity values and associated effects information.
