A) The cell cycles of CRC SW480 cells. B) The apoptosis rate of CRC SW480 cells. SW480 cells were plated and transfected with negative control or miRNA-199a mimics for 72 h. MiR-199a induced apoptosis of SW480 Cells. s. Flow cytometry analysis demonstrated that the percentage of the G0/G1, G2/M and S phase. The apoptosis rate was detected after transfection and tested with Annexin-V/PI.
