miR-21 inhibition induced cell-cycle arrest at G₂/M phase.

<p><b>A.</b> Cell number in each phase of cell cycle and apoptosis was detected by flow cytometry method. <b>B.</b> The percent of cell number at different phases of cell cycle (G₀/G₁, S and G₂/M). NC means negative control (transfected with pGCMV/EGFP-hsa-miR-NC plasmid) and data represent means of triplicates ± SD (n = 3, *p<0.05 versus corresponding control).
