Se-methylselenocysteine (SMC) is a major selenium compound found in selenium-rich plants, which possesses unique biological properties such as antioxidants. However, the effect of SMC on DEHP-induced testicular injury and the specific mechanism remains unknown. In this study, 50 mice were randomly divided into 5 groups and were given corn oil (Control), DEHP, low-dose SMC (L-SMC), moderate-dose SMC (M-SMC), or high-dose SMC (H-SMC). The sperm quality of the mice in each group was determined, and HE staining and transmission electron microscopy (TEM) were applied to observe testicular morphology, and testicular tissues were collected for the subsequent molecular biological analyses. The TM4 cell line was applied in vitro for mechanism validation. Our results showed that DEHP could lead to decreased sperm quality and blood-testis barrier damage in mice, which could be alleviated by SMC. Mitochondrial damage accompanied by accumulation of total iron content, MDA, and 4-HNE, as well as downregulation of antioxidants SOD, GSH, and GSH-Px were observed after DEHP treatment, which exhibited a typical ferroptosis feature. In vitro experiments confirmed that SMC promoted upregulation of GPX4 in TM4 cells and was able to alleviate DEHP metabolite MEHP-induced ferroptosis and promote the expression of cell junction key proteins ZO-1, Occludin, and Connexin 43, which could be inhibited by the GPX4 inhibitor RSL3 or the Nrf2 inhibitor ML385. Overall, the above results suggest that SMC ameliorates the DEHP-induced ferroptosis in testicular Sertoli cells, protects the blood-testis barrier, and prevents sperm aberrations via the Nrf2/GPX4 axis.</p>","PeriodicalId":11756,"journal":{"name":"Environmental Toxicology","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we investigate the involvement of the most used agrochemicals in Brazil with CZS. First, we exposed human neuroblastoma SK‐N‐AS cells to the 15 frequently used agrochemical molecules or derivative metabolites able to cross the blood–brain barrier. We found that a derived metabolite from a widely used herbicide in the Central‐West region, 2,4‐dichlorophenoxyacetic acid (2,4D), exacerbates ZIKV neurotoxic effects in vitro. We validate this observation by demonstrating vertical transmission leading to microcephaly in the offspring of immunocompetent C57BL/6J mice exposed to water contaminated with 0.025 mg/L of 2,4D. Newborn mice whose dams were exposed to 2,4D and infected with ZIKV presented a smaller brain area and cortical plate size compared to the control. Also, embryos from animals facing the co‐insult of ZIKV and 2,4D exposition presented higher Caspase 3 positive cells in the cortex, fewer CTIP2+ neurons and proliferative cells at the ventricular zone, and a higher viral load. This phenotype is followed by placental alterations, such as vessel congestion, and apoptosis in the labyrinth and decidua.
