【Objective】 To study the influence of corosolic acid(CRA) on the growth of human lung carcinoma A549 cells and discuss the mechanism of its antitumor action. 【Methods】 MTT method was used to detect the influence of CRA on A549 lung cancer cell growth in vitro under different concentrations. The nude mouse tumor model carrying bioluminescence-marked lung cancer cells A549 was established. IVIS small animal in vivo imaging system was used to detect the growth of solid tumor. The expressions of vascular endoth...
