Effect of nocodazole on cell cycle distribution in transduced cells. Cells were treated as described in Fig 5 except for 48 hours. G0/G1, S, and G2/M DNA contents are shown. Data are the averages ± SD from three separate experiments. *Significant difference from untreated control, P < .05. Low NOC was 0.15 μg/mL and high NOC was 15 μg/mL.
