Nitrosamines are a kind of easy to contact food pollutants, widely exist in pickled food (10.2-14.8 mg/kg) and contaminated water sources (10-150 ng/L), etc. They have been confirmed to be carcinogenic, but the reproductive and developmental toxic effects of nitrosamines have not been systematically reported. Based on relevant researches, the classification, distribution and metabolism kinetics of nitrosamines were summarized in this review. In addition, nitrosamines can inhibit testosterone synthesis (Leydig cells) and spermatogenesis (spermatogenic cells) in F0 male, and reduce ovary functions in F0 female, finally induce parental reproductive toxic effects. Meanwhile, the effects of parental (including maternal pregnancy, paternal) nitrosamine exposure on offspring development (such as cancer susceptibility) and related research deficiencies were summarized. To sum up, this paper systematically reviewed the reproductive and developmental toxic effects caused by exposure to nitrosamines, enabling people to fully understand the negative effects of nitrosamines on the body, so as to effectively avoid and reduce intake in daily life, and at the same time provide a theoretical and literature basis for guiding the healthy life and maintaining fertility.</p>","PeriodicalId":105,"journal":{"name":"Toxicology Research","volume":"14 2","pages":"tfaf051"},"PeriodicalIF":2.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12001771/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its precise role in nasopharyngeal carcinoma (NPC) remains unclear. This study investigated the effects of AS-IV on NPC progression and its relationship with Special AT-rich binding protein-2 (SATB2), a diagnostic marker for NPC. AS-IV treatment reduced NPC cell viability in a dose-dependent manner, as assessed by CCK-8 assays. Functional experiments, including transwell, immunofluorescence, and flow cytometry assays, demonstrated that AS-IV inhibited cell migration, invasion, and autophagy while promoting apoptosis. Western blot analysis showed that SATB2 expression was significantly elevated in NPC cells, particularly in C666-1 and HK-1 cells. Overexpression of SATB2 partially reversed AS-IV's inhibitory effects on NPC progression. Further analysis revealed that AS-IV suppressed the Wnt signaling pathway by downregulating SATB2 expression, while SATB2 overexpression restored Wnt pathway activation. This effect was reversed upon treatment with the Wnt pathway inhibitor DKK-1. In vivo, AS-IV administration inhibited tumor growth in a nude mouse subcutaneous xenograft model, reduced Ki-67 positivity, and lowered LC3B expression, indicating decreased proliferation and autophagy. However, these effects were diminished upon SATB2 overexpression. These findings suggest that AS-IV exerts anti-tumor effects in NPC by downregulating SATB2 and suppressing Wnt pathway activation, highlighting its potential as a therapeutic agent for NPC.</p><p><strong>Highlights: </strong>Astragaloside IV (AS-IV) reduces nasopharyngeal carcinoma (NPC) cell vitality, suppresses cell migration, invasion and autophagy, and fosters apoptosis.SATB2 exhibits notably high levels in NPC cells.Overexpression of SATB2 counteracts the inhibition of NPC malignant progression by AS-IV.AS-IV impedes NPC progression by decreasing SATB2 and thereby hindering the Wnt pathway.AS-IV deters NPC tumor growth in nude mice.</p>","PeriodicalId":105,"journal":{"name":"Toxicology Research","volume":"14 2","pages":"tfaf047"},"PeriodicalIF":2.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11964083/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
