Role of autophagy in GKB induced inhibition of invasion and colony formation of lung cancer cells. a Cell invasion analysis to assess the role of autophagy in GKB induced inhibition invasion of H1975 cells. b Colony formation analysis to assess the role of autophagy in GKB induced inhibition of the proliferation of H1975 cells. Data shown represent the mean ± SEM of three independent experiments. *P < 0.05, compared to the dimethyl sulfoxide (DMSO) only group
