The Block of Retrovirus Infection in Non-Cycling HCT116 p53^+/+ Cells Was Attenuated by p21^Cip1 siRNA Knockdown. The knockdown of p21^Cip1 by siRNA in HCT116 p53^+/+ cells were testified by Western Blot (a). p21^Cip1 siRNA transfected non-cycling HCT116 p53^+/+ cells were infected retrovirus. The infected GFP⁺ cells were analyzed by flow cytometer (b), and the percentage of infections was calculated (c). Non-target siRNA (NT) was used as negative control. The results represented a duplicated experiment. In Student’s t-test, p value < 0.05 is indicated by *
