Figure 2. CircMRPS35 contributes to apoptosis and regulates cell cycle of osteosarcoma cells. (A–F) The MG63 and MNNG/HOS cells were treated with circMRPS35 overexpressing plasmid. (A–D) The cell apoptosis was analyzed by flow cytometry analysis. (E, F) The cell cycle was determined by flow cytometry analysis. **P < 0.01.
