The body weight decreased depending on the degree of food restriction (FR). Cleavage of the balano-preputial skinfold was delayed, and cell debris in the epididymal lumen was noted as a related finding after four-week FR. Vaginal opening was also delayed, and some histopathological findings, such as absence of corpus luteum in the ovary, mucinous degeneration in the vagina, and immature uterus, were noted after eight-week FR. Erythrocyte count increased after four-week FR, but slightly decreased in males only after eight-week FR, and decreased leukocyte and/or reticulocyte counts, accompanied by related histopathological findings were noted after four- and eight-week FR. In blood chemistry, the levels of total protein including globulin, glucose, triglyceride, and calcium decreased, and sodium and chloride increased after four- and eight-week FR. Increases in activities of aspartate transaminase and lactate dehydrogenase and total bilirubin levels were noted after four-week FR, which were attenuated after eight-week FR. The effects of FR seemed to be more remarkable after four weeks. In drug safety evaluation, findings caused by malnutrition should be considered in juvenile toxicity studies when decreased food consumption is observed.","PeriodicalId":17654,"journal":{"name":"Journal of Toxicological Sciences","volume":"49 7","pages":"321-335"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141469110","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}

Oxycodone has anti-inflammatory properties. The purpose of this work was to look into the effect of oxycodone in controlling lipopolysaccharide (LPS)-induced neuroinflammation in microglia.Methods: LPS-induced HMC3 cells were subjected to oxycodone (2.5, 5, 10 and 20 μg/mL). The mRNA and protein expressions were examined by qRT-PCR and western blotting. TNF-α, IL-1β, IL-6, and IL-8 levels were assessed by ELISA. MTT assay was adopted to measure cell viability. The interactions between CREB, miR-181c and PDCD4 were analyzed by dual-luciferase reporter assay, ChIP and/or RIP assays.Results: Oxycodone treatment alleviated LPS-induced inflammation in HMC3 cells and increased p-CREB level, but reduced PDCD4 and iNOS levels in LPS-treated cells. Mechanistically, oxycodone mitigated LPS-induced neuroinflammation by upregulating miR-181c. In addition, CREB promoted miR-181c expression by directly binding to the MIR181C promoter, and miR-181c inhibited PDCD4 expression by directly binding to PDCD4 3'UTR. As expected, oxycodone alleviated LPS-induced neuroinflammation by regulating the CREB/miR-181c/PDCD4 axis.Conclusion: Oxycodone attenuated LPS-induced neuroinflammation in microglia by regulating the CREB/miR-181c/PDCD4 axis. These findings proved that oxycodone is a potential drug for treating neuroinflammation and elucidate the mechanisms involved.","PeriodicalId":17654,"journal":{"name":"Journal of Toxicological Sciences","volume":"49 10","pages":"435-446"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142365663","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}

Transcriptional enhanced associate domain (TEAD), a transcription activator of the Hippo pathway, forms the complex with a transcriptional coactivator yes-associated protein (YAP) or a transcriptional coactivator PDZ-binding motif (TAZ). Their excessive activations are involved in carcinogenesis such as malignant pleural mesothelioma (MPM), and thus inhibition of the TEAD complex is expected to have potent anticancer activity against MPM. On the other hand, YAP or TAZ conditional knockout mice have been reported to show abnormal findings in various tissues, including the kidney, liver, and lung. In the present study, we evaluated the systemic toxicity of K-975, a novel TEAD inhibitor, in rats. When K-975 was administered orally to rats for 1 week, proteinuria suggestive of nephrotoxicity was observed. Electron microscopy revealed that K-975 at 300 mg/kg induced glomerular podocyte foot process effacement. After a 2-week recovery period, proteinuria with foot process effacement was recovered completely. Urinalysis and urinary biomarker evaluation suggested that the urinary albumin index (urinary albumin/urinary creatinine) was the most sensitive marker for detecting K-975-induced nephrotoxicity. After 3 cycles of 1-week administration followed by 2-week recovery periods, nephrotoxicity was reversible; however, incomplete reversibility was observed in rats with severe proteinuria. In conclusion, this study revealed that in rats, oral K-975 treatment induced severe proteinuria by podocyte foot process effacement, which was reversible and monitorable by the urinary albumin index, suggesting important information for developing K-975 as an anticancer drug.","PeriodicalId":17654,"journal":{"name":"Journal of Toxicological Sciences","volume":"49 4","pages":"175-191"},"PeriodicalIF":2.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140331865","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 logP values of approximately 200 diverse chemicals (test plus reference compounds covering all 25 blocks of the chemical space) were estimated experimentally using retention times in reverse-phase liquid chromatography; these values were compared with those of authentic reference compounds with established logP values (available for 17 of 60 reference substances in the Organization for Economic Co-operation and Development Test Guideline 117). The logP values of 140 of 165 chemicals successfully estimated using four different mobile phase conditions (pH 2, 4, 7, and 10 for molecular forms) correlated significantly with those calculated using the in silico packages ChemDraw and ACD/Percepta (r > 0.72). Although substances that neighbored authentic compounds in the chemical space had precisely correlated logP values estimated experimentally and in silico, some compounds that were more distant from authentic substances showed lower logP values than those estimated in silico. These results indicate that additional authentic reference materials with wider ranging chemical diversity and their logP values from reverse-phase liquid chromatography should be included in the international test guidance to promote simple and reliable estimation of octanol/water partition coefficients, which are important determinant factors for the pharmacokinetics of general chemicals.","PeriodicalId":17654,"journal":{"name":"Journal of Toxicological Sciences","volume":"49 4","pages":"127-137"},"PeriodicalIF":2.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140331864","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}

DNA methyltransferases, epigenome-related enzymes, are inhibited in enzymatic activity by S-nitrosylation. Therefore, excess or chronic NO exposure may cause disease by altering gene expression. However, the effects of chronic NO exposure on transcriptome are poorly understood. Here, we performed transcriptome analysis of A549, AGS, HEK293T, and SW48 cells exposed to NO (100 μM) for 48 hr. We showed that the differentially expressed genes were cell-specific. Gene ontology analysis showed that the functional signature of differentially expressed genes related to cell adhesion or migration was upregulated in several cell lines. Gene set enrichment analysis indicated that NO stimulated inflammation-related gene expression in various cell lines. This finding supports previous studies showing that NO is closely involved in inflammatory diseases.

Traditional statistics-based bioinformatics analysis poses challenges in its application across multidimensional toxicogenomic data, including administration time, dosage, and gene expression levels. Motivated by the visual inspection workflow of field experts to augment their efficiency of screening significant genes to derive meaningful insights, together with the ability of deep neural architectures to learn the image signals, we developed DTox, a deep neural network-based in visio approach. Using the Percellome toxicogenomics database, instead of utilizing the numerical gene expression values of the transcripts (gene probes of the microarray) for dose-time combinations, DTox learned the image representation of 3D surface plots of distinct time and dosage data points to train the classifier on the experts' labels of gene probe significance. DTox outperformed statistical threshold-based bioinformatics and machine learning approaches based on numerical expression values. This result shows the ability of image-driven neural networks to overcome the limitations of classical numeric value-based approaches. Further, by augmenting the model with explainability modules, our study showed the potential to reveal the visual analysis process of human experts in toxicogenomics through the model weights. While the current work demonstrates the application of the DTox model in toxicogenomic studies, it can be further generalized as an in visio approach for multi-dimensional numeric data with applications in various fields in medical data sciences.","PeriodicalId":17654,"journal":{"name":"Journal of Toxicological Sciences","volume":"49 3","pages":"105-115"},"PeriodicalIF":2.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140022109","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}

However, accurately and reproducibly evaluating ferroptosis in cultured cells is challenging since numerous experimental factors in in vitro setting can influence the results. In the present study, we found that the expression levels of selenoproteins, such as GPx4 and GPx1, fluctuate across several cell lines depending on the selenium content of different origin of fetal bovine serum (FBS). Cells cultured in FBS containing higher selenium concentrations exhibited elevated GPx4 expression, and were resistant to ferroptosis induced by erastin and RSL3.
