ABSTRACT
Objective To investigate the effect of ellagic acid extracted from gallnut on multiple myeloma SP2 / 0 cell line and related mechanisms. Methods Multiple myeloma SP2 / 0 cell line was treated for 48 h with different concentrations of ellagic acid in vitro. Cell morphology,proliferation,apoptosis and cell cycle were analyzed with microscope,MTT experiment and flow cytometry,respectively. Tumor cell proliferation and apoptosis-related gene expression of COX-2 were detected by Western blotting. Results Cell cycle was arrested at the G1 phase 48 h after treatment with ellagic acid, the cell in G1 were (55. 21±3. 01)% , (64. 48 ± 0. 43)% , (75. 10 ± 2. 46)% , respectively, with significant difference as compared with control group [(34. 04±1. 74)% ,P<0. 01]. Cell suppression rate (21. 18±5. 92)% ,(44. 58±3. 43)% and (70. 15±2. 90)% ,respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups. Compared with the control group,the differences were significant (P<0. 01). Cell apoptosis rate was (9. 60 ± 0. 56)% , (19. 30 ± 1. 51)% and (35. 10 ± 5. 26)% , respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups,with significant differences as compared with the control group[(3. 23±0. 85)% ,P<0. 01]. With the increase of drug concentration,COX-2 expression was decreased. Conclusion Ellagic acid can inhibit myeloma SP2 / 0 cell proliferation and promote apoptosis.
