RBM5 inhibits proliferation of PC-3 cells. PC-3 cells were transfected with pcDNA3.1 or pcDNA3.1-RBM5 plasmids for up to 24 h and 48 h. Afterwards, (A) cell growth was evaluated by MTT assay. The data were presented as optical density in different groups. Data shown are means ± S.D. of three separate experiments. (B) Immunocytochemistry staining of PCNA. (C) Proliferation index of PCNA. * indicates significant difference as compared to the control and EV (P <0.05).
