ABSTRACT
OBJECTIVE@#To explore the effects of different concentration of pomalidomide on human multiple myeloma cell line MM1.S and the expression of CRBN.@*METHODS@#CCK-8 method was used for detecting inhibition effect of promalidomide on proliferation of MM1.S cells. Apoptosis rate of MM1.S cells was detected by flow cytometry with Annexin V-FITC/PI double staining. Real-time quantitative PCR was used to determine CRBN gene expression level. Western blot was used to detect the effect of pomalidomide on the protein expression of CRBN in MM1.S cells.@*RESULTS@#Pomalidomide has an inhibitory effect on MM1.S cells with time-and dose-dependent manners. Pomalidomide induced apoptosis in MM1.S cells. When the concentration of pomalidomide was 0, 40 and 80 μmol/L, the expression of CRBN gene after the treatment of MM1.S cells for 72 hours was 1.487±0.340, 0.211±0.054 and 0.055±0.005, by using actin as internal refereme. Pomalidomide significantly reduced CRBN protein expression in MM1.S cells.@*CONCLUSION@#Pomalidomide can inhibit the proliferation of MM1.S cells and promote its apoptosis. A certain concentration of pomalidomide can reduce the expression of CRBN gene and down-regulate its protein expression in MM1.S cells.
