Effect of nAChR antagonists on nicotine-induced apoptosis in PDLSCs. Cells were incubated with each α-BTX or mecamylamine for 1 h before 10−2 M nicotine treatment and (A) the DNA contents and (C) the level of DNA fragmentation of apoptotic cells were then determined. (B) The data shows the percentage of cells in the subG1 phase. The values reported are the mean ± S.D. of four independent experiments. *P < 0.05 vs. control value, **P < 0.05 vs. nicotine treatment.
