Ginkgolide B (GKB) inhibited the proliferation, invasion and colony formation of lung cancer cells in vitro and induced apoptosis.a GKB significantly inhibited the proliferation of lung cancer cells. b GKB significantly inhibited the invasion of lung cancer cell. c GKB significantly inhibited the colony formation of lung cancer cells. Scale bar, = 200 μm. d Cancer cells were incubated with GKB for 48 h, and then apoptotic cells (stained with annexin V and propidium iodide) were detected by flow cytometry. Results are presented as mean ± SEM of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, compared to the dimethyl sulfoxide (DMSO) only group
