Upregulation of p21WAF1/CIP1 is critical for G0/G1 arrest and consequent growth inhibition by GGCT knockdown. a-b The distribution of cell cycle phases in MCF7 cells was analyzed by flow cytometry 4 days after transfection with the indicated siRNAs. Representative histograms (a) and quantified distributions are shown (b). c-d The number of Trypan blue-negative viable MCF cells (c) and the proportion of dead cells (d) at 7 days after transfection with the indicated siRNAs are shown. (* p < 0.05, ** p < 0.01)
