From: p38α MAPK-mediated induction and interaction of FOXO3a and p53 contribute to the inhibited-growth and induced-apoptosis of human lung adenocarcinoma cells by berberine

Figure 1

Berberine (BBR) inhibited human lung carcinoma cell growth and caused G0/G1 arrest in a dose- and time-dependent manner. A, A549 cells were treated with increased concentrations of BBR for 48 h to examine the cell viability. B, A549 cells were treated with BBR (50 μM) for the indicated time to examine the cell viability. C, NSCLC cell lines indicated were treated with BBR (50 μM) for 48 h. The cell viability was determined using the MTT assay as described in the Materials and Methods Section and was expressed as percentage of control in the mean ± SD of three separate experiments. *indicates significant difference as compared to the untreated control group (P < 0.05). D, A549 cells were treated with increased doses of BBR for 24 h. Afterwards, the cells were collected and processed for analysis of cell cycle distribution by flow cytometry after propidium iodide (PI) staining. And the percentages of the cell population in each phase (G0/G1, S and G2/M) of cell cycle were assessed by Multicycle AV DNA Analysis Software. Data are expressed as a percentage of total cells. Values are given as the mean ± SD from 3 independent experiments performed in triplicate. *indicates significant difference as compared to the untreated control group (P < 0.05).
