IRF7 suppresses OS cell proliferation and promotes cell apoptosis. (A) The growth rate of over-vector and over-IRF7 Saos-2 and MNNG-HOS was monitored by the plate colony formation assay. (B) The growth rate of sh-Ctrl and sh-IRF7 KHOS cells in the complete medium was determined by the plate colony formation assay. (C) In the culture medium, glucose was replaced by galactose; then, the growth rate of sh-Ctrl and sh-IRF7 KHOS cells in culture was determined by the plate colony formation assay. (D) The cell cycle status of over-vector and over-IRF7 Saos-2 and MNNG-HOS cells was analyzed by flow cytometry. (E) The cell cycle status of sh-Ctrl and sh-IRF7 KHOS cells was analyzed by flow cytometry. (F) The cell apoptosis status of over-vector and over-IRF7 Saos-2 and MNNG-HOS upon serum starvation for 24 h was determined by the Caspase3-7 activity assay. (G) The cell apoptosis status of sh-Ctrl and sh-IRF7 KHOS upon serum starvation for 24 h was determined by the Caspase3-7 activity assay. *P < 0.05; **P < 0.01; ***P < 0.001.
