A. Nuclear morphologic changes showing features of apoptosis in SGC7901 cells after treatment with arsenic trioxide for 24 hours. (a) Untreated SGC7901 cells; (b-f) 15 μmol/L arsenic trioxide-treated SGC7901 cells. The cells were stained using DAPI staining. B. Untreated SGC7901 cells stained by anti-Bcl-2 N terminus antibody. C SGC7901 cell stained by anti-Bcl-2 BH3 and anti-Bax(6A7) antibody before and after exposure to 15 μmol/L arsenic trioxide for 12 hours.
