OBJECTIVE: To investigate the effect of Arsenic trioxide (ATO) combined with Norcantharidin (NCTD) on the proliferation and apoptosis of Jurkat cells, and to evaluate its effect on the proliferation and apoptosis of acute T-lymphoblastic leukemia (T-ALL) based on the Wnt/β-catenin signaling pathway.
METHODS: Jurkat cell lines were used as the study subjects and treated with different concentrations of ATO (0, 2, 4, 8, 16 μmol/L) and NCTD (0, 10, 25, 50, 100 μmol/L) for 72 hours, and the cell proliferation was detected by CCK-8. Meanwhile, flow cytometry was used to detect the apoptosis rate, EdU staining to detect cell proliferation viability, cell clone formation assay to assess cell cloning ability, Transwell assay to assess cell invasion ability, and Western blot to detect apoptosis and the expression of Wnt/β-catenin signaling pathway-related proteins.
RESULTS: Compared with the control group, both ATO and NCTD effectively inhibited Jurkat cell proliferation when used alone, and the inhibition effect was more significant when used in combination ( P < 0.05). The combination significantly increased the apoptosis rate of Jurkat cells ( P < 0.05). Meanwhile, the combination significantly decreased the proliferation vitality and clone formation ability of the cells ( P < 0.05), and inhibited the invasion ability of Jurkat cells ( P < 0.05). Western blot analysis showed that the combination of ATO and NCTD significantly up-regulated the expression of pro-apoptotic proteins Bax and E-cadherin, and down-regulated the expression of anti-apoptotic proteins Bcl-2, c-myc and Cyclin D1 ( P < 0.05).
CONCLUSION: The combination of ATO and NCTD had a synergistic effect in inhibiting proliferation and promoting apoptosis in Jurkat cells, which may be related to the inhibition of Wnt/β-catenin signaling pathway.
