ABSTRACT
Background and

purpose:

Recently, it was reported that tanshinoneⅡA (TanⅡA) could inhibit proliferation, induce differentiation and apoptosis of human cancer cells. Previous studies also indicated that TanⅡA could inhibit the migration and invasion of osteosarcoma. However, the effects of TanⅡA on the migration and invasion of gastric cancer and the mechanism remains unclear. The aim of this study was to investigate the effect of TanⅡA on gastric cancer cell SGC7901 migration and invasion of in vitro.

Methods:

After different concentrations (0.5, 1, 2, and 4μg/mL) of TanⅡA treatment for 24, 48, and 72 h respectively, MTT assay were developed to detect the cell proliferation of SGC7901. The wound healing assay and 3D-transwell assay were used to observe the migration and invasion of SGC7901 cells, respectively. Expression of intercellular adhesion molecule 1 (ICAM-1), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase 2 (TIMP-2) mRNA and protein were measured with real-time PCR and Western blot.

Results:

1, 2, and 4 μg/mL Tan ⅡA showed a dose-and time-dependent growth inhibition on SGC7901 cells. 2μg/mL TanⅡA showed a time-dependent migration inhibition of SGC7901 cells. 1, 2, and 4μg/mL TanⅡA could inhibit the invasion of SGC7901 cells. Real-time PCR and Western blot showed a reduction in expression of ICAM-1, MMP-2, and MMP-9, as well as an increase in expression of TIMP-2 (P<0.05).

Conclusion:

TanⅡA inhibits human gastric cancer SGC7901 cell migration and invasion in vitro. TIMP-2 upregulation and, ICAM-1, MMP-2, MMP-9 downregulation might be one of the mechanisms of anti-tumor of TanⅡA.
