TanIIa-induced NB4 apoptosis. (a) Giemsa staining of NB4 cells treated with TanIIa for 24 h. (b) Annexin V/PI staining of NB4 cells treated with TanIIa for 24 h. (c) The western blotting of apoptotic proteins in NB4 cells treated with TanIIa for 24 h. (d) The relative quantification of apoptotic proteins in NB4 cells treated with TanIIa for 24 h. Data were expressed as the mean ± SD of three independent experiments; , compared with the 0 μmol/L groups.
