Overexpression of PCNA Attenuates Oxidative Stress-Caused Delay of Gap-Filling during Repair of UV-Induced DNA Damage

Figure 3

Flow cytometric analysis of nucleoid size. AGS cells were treated similarly as those described in Figure 1. (a) Cont. for control, that is, cells without treatment. UV and UV col. for UV alone and UV then colcemid, respectively. Time points: 0–8 h after H/A removal. (b) Similar to (a), yet the cells were transiently transfected with the indicated expression plasmids. (Histogram: -axis: forward scattering; -axis: counts.)
