Description
Summary:The theranostic agent iron-quercetin complex (IronQ) provides a T1-positive magnetic resonance imaging (MRI) contrast agent. The magnetically IronQ-labeled cells can be used for cell tracking and have active biological applications in promoting cell and tissue regeneration. However, a detailed investigation of IronQ's cytotoxicity and genotoxicity is necessary. Thus, this study aimed to evaluate the possibility of IronQ inducing cytotoxicity and genotoxicity in peripheral blood mononuclear cells (PBMCs). We evaluated the vitality of cells, the production of reactive oxygen species (ROS), the level of antioxidant enzymes, and the stability of the genetic material in PBMCs treated with IronQ. The results show that IronQ had a negligible impact on toxicological parameters such as ROS production and lipid peroxidation, indicating that it is not harmful. IronQ-labeled PMBCs experienced an insignificant depletion of antioxidant enzyme levels at the highest concentration of IronQ. There is no evident genotoxicity in the magnetically IronQ-labeled PBMCs. The results show that IronQ does not potentiate the cytotoxicity and genotoxicity effects of the labeled PMBCs and might be safe for therapeutic and cell tracking purposes. These results could provide a reference guideline for the toxicological analysis of IronQ in in vivo studies.
