ABSTRACT
OBJECTIVE@#To investigate the effect of artesunate and arsenous acid and their combination on the proliferation and apoptosis of human multiple myeloma cells and their mechanism.@*METHODS@#Human multiple myeloma cell line RPMI 8226 cells were cultured and treated with 0, 1, 2, 4, 8 nmol/L arsenous acid and 0, 40, 80, 160, 320 μmol/L artesunate, respectively. The inhibition of cell growth was detected by CCK-8 assay. The apoptosis rate was detected by flow cytometry. QPCR was used to detect the mRNA expression of cell proliferation and apoptosis-related factors. The expression of cell proliferation, apoptosis-related factors and PI3K/AKT pathway protein were detected by Western blot.@*RESULTS@#CCK-8 assay showed that the growth of multiple myeloma cells was inhibited by arsenous acid and artesunate. The IC@*CONCLUSION@#Artesunate combined with arsenous acid inhibits proliferation and promotes apoptosis of tumor cells through PI3K/AKT signaling pathway, and is superior to the effect of two drugs alone.
