Growth curves of A2780 cells with or without CXCL1 expression were plotted by MTT assay. Cell cycles were measured by flow cytometry. Cell colony formation was enumerated in Transwell chambers. Migration and invasion in vitro were investigated using Cell Counting Kit-8 (CCK8), wound healing and Transwell, respectively. The relationship between CXCL1 gene mRNA expression and ovarian tumor clinical pathology was analyzed.Results: CXCL1 was found to be one of the co-upregulated differentially expressed genes in the GEO database. The migration of A2780 cells expressing CXCL1 was significantly higher than that of A2780 cells without CXCL1 expression. CXCL1 mRNA expression in ovarian malignancy was significantly higher than those in benign lesions and the normal control (p < .01). In advanced ovarian cancer (Stages III-IV), CXCL1 mRNA expression was also significantly higher than that in patients with early-stage ovarian cancer (Stages I-II) (p = .005). Kaplan-Meier survival curve showed no correlation between CXCL1 mRNA expression and ovarian cancer prognosis. A Cox proportional hazard model also showed that CXCL1 expression was not an independent prognostic factor for ovarian cancer patients.Conclusions: CXCL1 gene could promotes ovarian cancer A2780 cell proliferation and invasion in vitro, and contributed theoretical knowledge for the target selection in molecular targeted therapy. CXCL1 mRNA over-expression may be correlated with the occurrence and development of ovarian malignancy. Level of plasma CXCL1 might serve as a biomarker for prognosis in ovarian carcinoma patients.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41175893","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}

This study aimed to investigate the underlying pathophysiology of MP-induced skeletal deficits in growing rats using stereological and immunohistochemical methods. Male rats, aged 4 weeks, were orally treated with MP through an 8-h/day water drinking protocol. The rats (n=30) were randomly divided into three groups: MP-High Dose (30/60 mg/kg/day MP), MP-Low Dose (4/10 mg/kg/day MP), and control (water only). After 13 weeks, the femoral bones were assessed using calliper measurements, dual-energy X-ray absorptiometry, and biomechanical evaluation. The total femur volume, cartilage volume, growth zone volume, and volume fractions were determined using the Cavalieri method. Immunohistochemical analyses were conducted using alkaline phosphatase and anti-calpain antibody staining. Rats exposed to MP exhibited significant reductions in weight gain, femoral growth, bone mineralization, and biomechanical integrity compared to the control group. The total femoral volume of MP-treated rats was significantly lower than that of the control group. The MP-High Dose group showed significantly higher ratios of total cartilage volume/total femoral volume and total growth zone volume/total femoral volume than the other groups. Immunohistochemical evaluation of the growth plate revealed reduced osteoblastic activity and decreased intracellular calcium deposition with chronic MP exposure. The possible mechanism of MP-induced skeletal growth retardation may involve the inhibition of intracellular calcium deposition in chondrocytes of the hypertrophic zone in the growth plate. In this way, MP may hinder the differentiation of cartilage tissue from bone tissue, resulting in reduced bone growth and mineralization.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71416363","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}

Its antitumoral effects are achieved by interfering with the synthesis of RNA and DNA and by inhibiting thymidylate synthase in both malignant and non-malignant cells. Therefore, it can be responsible for severe toxicities in crucial body organs, including heart, liver, kidney, and reproductive system. Given the fact that 5FU-induced reproductive toxicity may limit the clinical application of this drug, in this study, we aimed to discuss the main locations and mechanisms of the 5FU-induced reproductive toxicity. Initially, we discussed the impact of 5FU on the male reproductive system, which leads to damage of the seminiferous epithelial cells and the development of vacuoles in Sertoli cells. Although no noticeable changes occur at the histopathological level, there is a decrease in the weight of the prostate. Additionally, 5FU causes significant abnormalities in spermatogenesis, including germ cell shedding, spermatid halo formation, polynucleated giant cells, and decreased sperm count. Finally, in females, 5FU-induced reproductive toxicity is characterized by the presence of atretic secondary and antral follicles with reduced numbers of growing follicles, ovarian weight, and maturity impairment.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138814220","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}

Whether it inhibits gastric cancer through ferroptosis has not been reported. This study aimed to confirm the effect of Tan I on ferroptosis in gastric cancer cells.Methods: AGS and HGC27 cells were treated with Tan I. First, oxidative stress-related parameters and the expression of ferroptosis-related proteins were examined. Combined with a ferroptosis inhibitor, Tan I was found to inhibit gastric cancer cells via the ferroptosis pathway. Finally, with bioinformatics analysis, the target protein of Tan I was identified.Results: Tan I significantly inhibited the expression level of GPX4. This molecule also increased ROS, MDA, and Fe2+ contents and decreased GSH enzyme activity. Therefore, we hypothesized that Tan I may inhibit gastric cancer cells by inducing ferroptosis. Western blotting results showed that Tan I inhibited the expression levels of the ferroptosis resistance-related proteins GPX4, SLC7A11, and FTH1, while the pro-ferroptosis-related proteins TFR1 and ACSL4 were significantly upregulated. A ferroptosis inhibitor effectively reversed these regulatory effects of Tan I in gastric cancer. With these data combined with the bioinformatics analysis, KDM4D was identified as a key regulatory target of Tan I. Mechanistically, Tan I induced positive regulation of ferroptosis resistance-related indicators by inhibiting KDM4D to upregulate p53 protein expression. Overexpression of KDM4D significantly reversed the effect of Tan I-induced ferroptosis resistance in gastric cancer cells.Conclusions: Tan I induced ferroptosis inhibition in gastric cancer by regulating the KDM4D/p53 pathway.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138292641","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}

This study used an integrated network analysis of microRNA (miRNA) and mRNA expression profiles, biochemical and pathological analyses to further investigate these potential mechanisms of CsA-induced AKI. Small RNA sequence analysis identified 25 differentially expressed miRNAs, RNA sequencing analysis identified 4,109 differentially expressed mRNAs. We obtained a total of 4,367 target genes from the 25 differentially expressed miRNAs based on three algorithms, including the Mirdb, Mirtarbase, and TargetScan. 971 target genes overlapped between the 4,367 target genes and 4,109 differentially expressed mRNAs were identified for further bioinformatics analysis. Finally, 30 hub genes and two main modules were recognized. Functional enrichment analysis of 30 hub genes indicated that inflammation and epithelial-mesenchymal transition (EMT) related genes were mainly concentrated together. Pathway analysis revealed that the PI3K-Akt signaling pathway plays an integral role in CsA-induced AKI. Network analysis identified 3 important miRNAs, mmu-miR-17b-5p, mmu-miR-19b-3p, and mmu-mir-423-5p that may further promote the development of inflammatory responses and EMT by mediating a complex network of factors.
