Effects of Lm-PHB2 on the proportion of cells in different phases of the cell cycle. HeLa cells were transfected with pEGFP-N1 or pEGFP-N1-Lm-PHB2 at 37 °C for 36 h followed by PI staining and flow cytometry analysis. The histogram shows the percentage of G2/M phase cells in both groups. Data are the means ± SDs from three experiments. ‘*’ indicates significantly different from PBS-treated cells at the P < 0.05 level.
