Objective: To investigate the effect of ganoderic acid A (GA-A) on the biological behaviors of human osteosarcoma cells in vitro.
Methods: MG63 and HOS cells were treated with 0.1, 0.25, and 0.5 mmol/L GA-A, and the changes in cell proliferation, Apoptosis and migration were evaluated using MTT assay, flow cytometry, and Transwell assay, respectively. The expressions of STAT3, p38, and NF-κB1 in the cells were analyzed by Western blotting.
Results: GA-A effectively inhibited the proliferation of human osteosarcoma HOS and MG-63 cells in a dose-dependent manner, and induced obvious cell Apoptosis in both cells. Treatment with 0.5 mmol/L GA-A also resulted in significant inhibition of the invasion of both cells. The results of Western blotting showed that GA-A down-regulated the expression level of phosphorylated STAT3 and increased the phosphorylation level of p38 and NF-κB1 expression in both cells.
Conclusion: GA-A can induce proliferation inhibition, Apoptosis and suppression of invasion in human osteosarcoma HOS and MG-63 cells.
