Effect of Sunitinib on Pyroptosis of Drug-Resistant Leukemia K562/ADR Cells and Its Pathway
OBJECTIVE: To investigate the inducing effect of sunitinib on the death of drug-resistant leukemia K562/ADR cells and the related signaling pathway.
METHODS: K562/ADR cells were treated with different concentrations of sunitinib, and the cells were collected at 24, 48, 72, and 96 hours, respectively. MTS assay was used to detect the effect of sunitinib on the proliferation of K562/ADR cells, and the appropriate sunitinib intervention time and concentration were determined. QPCR and Western blot were used to detect the mRNA and protein expression levels of apoptosis-related genes in K562/ADR cells treated with sunitinib. Four different cell death inhibitors Nec-1, VX-765, CQ and Fer-1 were used to detect the death mode of K562/ADR cells treated with sunitinib. QPCR and Western blot were used to detect the mRNA and protein expression levels of pyroptosis-related genes in K562/ADR cells treated with sunitinib.
RESULTS: Sunitinib significantly inhibited the proliferation of K562/ADR cells in a time - and concentration-dependent manner(R48 H=0.9579, r4 μg/ml=0.9740). The IC50 of sunitinib was (3.96±0.14) μg/ml at 48 hours. The mRNA and protein expression levels of apoptosis-related genes Bax, BCL-2 , Caspase-3 and Caspase-9 in K562/ADR cells treated with sunitinib did not change significantly. After treatment with four different cell death inhibitors, only the pyroptosis inhibitor VX-765 could significantly reverse the inhibitory effect of sunitinib on the proliferation of K562/ADR cells (P<0.01). The mRNA and protein expression levels of pyroptosis-related genes Caspase-1, Caspase-4, Caspase-5, NLRP3, GSDMD and IL-1β in K562/ADR cells treated with sunitinib were significantly increased (P<0.01).
CONCLUSION: Sunitinib can induce pyroptosis in drug-resistant leukemia K562/ADR cells. Further study of the signaling pathways related to pyroptosis may provide experimental basis for the treatment of drug-resistant leukemia.
