The quantitative in situ TUNEL assay, in parallel with the MTT assay, was performed after 1-, 2-, 4-, 6-, and 24-h exposure. As shown in Figure 1, even 1 h of exposure to 5% CSE or CPT caused a significant increase of TUNEL-positive cells (54.9 ± 3.0% by 5% CSE and 31.2 ± 2.2% by CPT, respectively, P < 0.05 compared with control of 16.2 ± 0.3%, Figure 1A). TUNEL-positive cells gradually increased to nearly 90% in both 5% CSE- and CPT-treated groups as a function of time, although the 5% CSE effect was stronger than 1 µM CPT during the first 4 h. Cell viability as assessed by MTT, however, was not affected by 5% CSE but was significantly reduced by CPT at 6 h (100.3 ± 3.3% versus 61.3 ± 5.5% of control, P < 0.05) and at 24 h (103.2 ± 7.6% versus 26.6 ± 1.9% of control, P < 0.05; Figure 1B). Cigarette smoke-induced DNA damage was dependent on CSE concentration.
