Figure 4. DNA content.
Panel A: DNA content, expressed as a % of control cell values, of A549 cells after 24, 48 or 72 hr exposure to 100 μg/ml CB, crocidolite or 100 μg/ml MWCNT in 1% DPL, EtOH, or PBS.
Panel B: DNA content, expressed as a percentage of control cell values, of MeT5A cells after 48 hr exposure to 100 μg/ml CB, crocidolite or 100 μg/ml MWCNT in 1% DPL. *p<0.05 vs control condition.
