Abstract: ObjectiveTo discuss the mechanism of the growth inhibitory effects of berberine on human osteosarcoma cell MG63.MethodsMG63 cells were divided into a control group and a processing group.The inhibition ratio of two groups was measured by CCK-8 assay,and the mechanism of the growth inhibitory effect was studied by Western Blot assay.ResultsThe inhibition ratio of MG63 cells,which were respectively treated with berberine at 0 (control group),1,5,10,20,50 μg/ml,were (99.37± 1.13) ％,(91.37±4.25)％,(72.44 ± 2.89)％,(57.33 ± 1.37)％,(50.14 ± 4.05)％ and(37.53 ± 4.14)％ after 48h.The semiquantitative expression of Bcl-2 in MG63 treated with berberine at 0 (control group),20,50 μg/ml after 48h was (0.4167±0.0115),(0.3458±0.0146),(0.2987±0.0207),while the Bax and caspase-9 was (0.4327±0.0206),(0.5007±0.0089),(0.7115±0.0214) and (0.1459±0.0107),(0.2416±0.0098),(0.2584±0.0330).Compared with the control group there was statistically significance (P＜0.05).ConclusionBerberine had inhibitory effects of on MG63.The mechanism lied in its regulating the expression of apoptosis gene Bcl-2 and Bax,activating caspases-9,and inducing cell apoptosis.
