Background: One of the acute hematologic malignancies is acute promyelocytic leukemia (APL) that resulted in translocation of chromosomes 15 and 17, t (15; 17), and cessation in the maturation of myeloid cell line, and ultimate aggregation of neoplastic promyelocytes. Regarding that appetence of using herbal and marine medicine studies is increasing, and on the other hand, the features of Cassiopea andromeda Venom remained unclear; this study was conducted to determine its effects on NB4 cells as a model for APL.
Materials and Methods: In this experimental study, the cells were treated with C. andromeda Venom concentrations at different periods and times. Growth inhibition and toxic effects of C. andromeda Venom were evaluated through methyl thiazole tetrazolium salt reduction (MTT test). The flow cytometry analysis was carried out using 7AAD and Annexin V stains for evaluating this venom’s effect on apoptotic pathways. Besides, Real-Time polymerase chain reaction was performed to evaluate the relative gene expression.
Results: C. andromeda Venom inhibited the growth of NB4 cells as correlated with concentration and time. Cell growth was inhibited by 49.1%, after 24 hours of treating NB4 cells with 1000µg/mL C. andromeda Venom. This venom increased the apoptotic process, which was then verified by 7AAD/AnnexinV staining. The fold change of p15INK4b, p21 WAF1/CIP1, P53, DNMT1, and Bcl-2 genes in the NB4 cell line were 144, 2.78, 1.75, 15.24, and 0.33, respectively, which meant that the expression level of p15INK4b, p21 WAF1/CIP1, P53, and DNMT1 were increased by 14400%, 278%, 175%, and 1524%, respectively and the expression of Bcl-2 was decreased by 67%.
Conclusion: Considering the inhibitory property of C. andromeda Venom, the authors recommended it as a part of combinational medication for treating APL in animal trials and for other leukemias’ in vitro studies.
