sCLU regulates osteosarcoma cell growth by modulating ERK1/2 expression. (A) Cell proliferation was assessed at the indicated times by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. Data are from three independent experiments. *P < 0.05, compared to the control group. (B) Cell proliferation was assessed at the indicated times by MTT assays. Data are from three independent experiments. *P < 0.05, compared to the KH OS/sCLU group.
