Objective To investigate the effect of silibinin on proliferation and invasion of breast cancer cells and the underlying mechanism. Methods Human breast cancer cell line MCF-7 were treated with various concen-trations of silibinin for 24h, then MTT assay was used to detect cell proliferation. The effect of silibinin on inva-sion of MCF-7 cells was measured by transwell. The phosphorylation of MEK and ERK proteins and the expression of MM-9 protein were evaluated by western blot. Results The inhibitory rate of silibinin on MCF-7 cell prolifer-ation was (8.9±3.8)% at 20μM, (19.7±4.2)% at 50 μM, and (29.8±5.7)% at 100μM, with significant difference compared with control group(P<0.05). Typan blue staining rate of MCF-7 cells treated with silibinin at concentration of 50 and 100μM was (16.1±4.8)% and (25.3±5.1)%, respectively, both with significant difference compared with that of control group [(3.4±1.4)%, P<0.05]. Silibinin at concentration of 20, 50, and 100μM inhibited the phospho-rylation of MEK (0.26±0.03, 0.15±0.03, 0.11±0.02 vs 0.35±0.04) and ERK (0.23±0.03, 0.12±0.02, 0.07±0.01 vs 0.32±0.05) proteins. Silibinin of 50 and 100μM decreased the expression of MMP-9 protein (0.18±0.03, 0.14±0.02 vs 0.29±0.04). Silibinin inhibited metastasis and invasion of MCF-7 cells[20μM:(14.3±2.1%), 50μM:(35.6±5.7)%, 100μM:(53.1±6.5)% vs 0]. Conclusion Silibinin can inhibit the growth and invasion of breast cancer cells.
