Natural pyrethrins induced developmental toxicity of zebrafish swim bladder in vivo and genotoxicity of lung cells in vitro
Natural pyrethrins (NPs) are insecticidal compounds isolated and extracted from pyrethrum flowers and are primarily use to control sanitary pests. The lungs become the main target after exposure, and its use may pose potential hazards to respiratory health. Therefore, in this paper, the toxic effects of NPs on human lung cells A549 were investigated and the risk of respiratory toxicity of NPs was studied using zebrafish swim bladder as a model. The results showed that NPs induced cytotoxicity, caused oxidative DNA damage and triggered mitochondria-mediated apoptosis. In addition, exposure to NPs decreased zebrafish embryo survival, hatchability, and heartbeat, and may inhibit normal swim bladder development by disrupting Wnt and Hedgehog signaling pathways. In conclusion, our results suggest that NPs can induce cytotoxicity in A549 in vitro and developmental toxicity in zebrafish in vivo. This study provides a conceptual basis for understanding the mechanisms of toxicity of NPs and assessing respiratory health risks in humans.
期刊介绍：
Toxicology in Vitro publishes original research papers and reviews on the application and use of in vitro systems for assessing or predicting the toxic effects of chemicals and elucidating their mechanisms of action. These in vitro techniques include utilizing cell or tissue cultures, isolated cells, tissue slices, subcellular fractions, transgenic cell cultures, and cells from transgenic organisms, as well as in silico modelling. The Journal will focus on investigations that involve the development and validation of new in vitro methods, e.g. for prediction of toxic effects based on traditional and in silico modelling; on the use of methods in high-throughput toxicology and pharmacology; elucidation of mechanisms of toxic action; the application of genomics, transcriptomics and proteomics in toxicology, as well as on comparative studies that characterise the relationship between in vitro and in vivo findings. The Journal strongly encourages the submission of manuscripts that focus on the development of in vitro methods, their practical applications and regulatory use (e.g. in the areas of food components cosmetics, pharmaceuticals, pesticides, and industrial chemicals). Toxicology in Vitro discourages papers that record reporting on toxicological effects from materials, such as plant extracts or herbal medicines, that have not been chemically characterized.
