BACKGROUND: Leukemia is a malignant hematologic disease that poses a serious threat to human health. Realgar-Indigo Naturalis formula (RIF), a traditional Chinese medicine formula, have demonstrated anti-tumor activity, but its mechanisms of action remain unclear.
OBJECTIVE: This study aimed to establish a zebrafish HL-60 tumor transplantation model to investigate the anti-leukemic effects of RIF and explore its underlying mechanisms.
METHODS: The zebrafish HL-60 tumor transplantation model was established, with RIF as the intervention drug and all-trans retinoic acid (ATRA) as the control. Anti-tumor efficacy was assessed via pharmacodynamic analysis. Transcriptomic analysis further elucidated gene expression profiles, differentially expressed genes, and relevant biological pathways.
RESULTS: RIF significantly reduced tumor cell fluorescence intensity, demonstrating anti-tumor efficacy. Additionally, it improved HL-60-induced liver damage in zebrafish, as evidenced by a reduction in fatty vacuolar degeneration in liver tissue. Transcriptomic analysis revealed that ATRA mainly affected the FoxO signaling pathway, PI3K-Akt signaling pathway, apoptosis, and complement and coagulation cascades in leukemia treatment. RIF primarily influenced the ubiquitin-proteasome system, ferroptosis, and glutathione metabolism. The combination of ATRA and RIF also affected autophagosome and lysosome pathways, in addition to the aforementioned pathways.
CONCLUSION: RIF exhibit significant anti-tumor effects through modulation of multiple pathways. This study provides a theoretical foundation for the potential clinical application of RIF in leukemia treatment.
