The Effects of Chidamide Combined with Anti-myeloma Drugs on the Proliferation and Apoptosis of Myeloma Cells / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the effects of chidamide combined with anti-myeloma drugs on the proliferation and apoptosis of myeloma cells.@*METHODS@#The proliferation inhibition of the cells was detected by CCK-8 method, and flow cytometry was used to detected the apoptosis of the cells.@*RESULTS@#Chidamide could inhibit the proliferation of myeloma cells and promote the apoptosis of primary myeloma plasma cells in a time- and dose-dependent manner (P<0.05). In NCI-H929 cell line, chidamide combined with low-dose bortezomib and lenalidomide showed synergistic effect, while combined with dexamethasone and pomalidomide showed additive effect. In MM.1s cell line, chidamide combined with bortezomib, dexamethasone, lenalidomide and pomalidomide all showed synergistic effects.@*CONCLUSION@#Chidamide inhibits proliferation of myeloma cells in a time- and dose-dependent manner and promotes apoptosis of primary myeloma plasma cells. Furthermore, it can enhance the inhibitory effect of anti-myeloma drugs.
