Study on the toxic mechanism of arsenic trioxide on K562 cells based on non-targeted metabolomics
Objective:To study the effect of arsenic trioxide(As2 O3)on the metabolism of leukemia K562 cells.Methods:Firstly,the effect of As2 O3 on the viability of K562 cells was detected by CCK-8 assay.Then,the metabo-lites in the cells after As2 O3 incubation were identified by ultra-high performance liquid chromatography-mass spec-trometry,and the differential metabolites were screened and KEGG enrichment analysis was performed.Results:CCK-8 results showed that As2 O3 could decrease the survival rate of K562 cells in a dose-dependent manner.The results of non-targeted metabolomics showed that As2 O3 could lead to significant changes in the content of multiple metabolites in K562 cells.KEGG enrichment analysis showed that the differential metabolites were mainly enriched in glutathione me-tabolism,ferroptosis,linoleic acid metabolism,taurine metabolism,choline metabolism in cancer,purine metabolism and other pathways.Conclusion:As2 O3 can significantly decrease the survival rate of K562 cells,which may be related to the influence of various metabolic homeostasis of cells,resulting in the inhibition of cell proliferation and the induction of apoptosis.In addition,whether As2 O3 can induce ferroptosis in K562 cells is still worthy of further study.
