This work addresses the impact of Cd, alone or combined with astaxanthin (ATX), in human non\u2010small cell lung cancer (NSCLC) cells (H1975) and nonmalignant bronchial epithelial cells (BEAS\u20102B). The endpoints selected comprise cell viability, migration, generation of reactive oxygen species (ROS), and a metabolomic study. Cd (up to 140\u00a0\u00b5M) was evaluated with the crystal violet (CV) and MTS assays and revealed cytotoxicity at high concentrations, with greater extent in nonmalignant cells. ATX (up to 20\u00a0\u00b5M) revealed no cytotoxicity. Cd increased ROS generation (dichlorodihydro\u2010fluorescein diacetate fluorometric assay) in a concentration\u2010dependent manner for both cell lines, with this effect being reverted by ATX. Cd at noncytotoxic concentrations (up to 10\u00a0\u00b5M) increased collective cell migration, with this pro\u2010migratory effect being mitigated upon ATX co\u2010treatment. The metabolome analysis yielded no significant metabolic alterations in the endo\u2010 or exometabolome. Overall, Cd exhibits cytotoxicity in lung cells, with differential sensitivity between nonmalignant and malignant cells. Importantly, Cd promotes NSCLC cell migration and ROS production in lung cells, which can be ameliorated by ATX, reinforcing the protective properties of this dietary carotenoid against toxic exposures.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mnfr.70141","type":"journal-article","created":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T03:53:36Z","timestamp":1750823616000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Protective
