【摘
要】 Objective To investigate whether Tanshinone ( Tan) ⅡA can inhibit osteosarcoma cells proliferation and migration by downregulating KLF-4. Methods The cells were treated with different concentrations of TanⅡA, MTT were used to investigate the proliferation of osteosarcoma cells. Transwell chambers and wound healing were employed to test the migratory ability of osteosarcoma cells. Western blotting used to investigate the expressions of p21, PCNA, ki-67, COL1A1, COL1A5, MMP-2, MMP-9, KLF-4 in osteosarcoma cells. After KLF-4 was transfected into osteo-sarcoma cells, the metheods were used again to test the proliferation and migration ability of osteosarcoma cells. Re-sults Compared with control group, the migration and proliferation ability of osteosarcoma cells was decreased in the TanⅡA group;Compared with control group, the expression of p21 in Tan ⅡA group was significantly increased (P |
