Fig. 3: β2SP suppressed the growth of HCC cells (SUN398 and Huh7 cells) in vitro.

The plasmids expressing β2SP were transfected into SUN398 and Huh7 cells. 48 h later, the cells were collected for further studies. a Quantitative RT–PCR determined β2SP mRNA in HCC cells transfected with the vector expressing β2SP cDNA or the control; b Western blot analysis determined β2SP protein in HCC cells transfected with the vector expressing β2SP cDNA or the control; c the percentages of cell distribution in each phase were determined in transfected HCC cells by flow cytometry. Percentages of cell distribution in each phase were shown on the histogram. d the expression patterns of cell cycle regulatory proteins were analyzed by western blot e the proliferation of HCC cells was evaluated by Cell Counting Kit-8 (CCK8). All the data were means ± SEM of three independent experiments (**P < 0.01, *P < 0.05)
