Rapamycin does not affect apoptosis in cycling or resting B-CLL cells.
(A) Annexin V and PI staining were performed in B-CLL cells after 48 or 72 hours of culture in the presence of medium alone or DSP30 and IL-2 (stimulated/activated[stim]) with or without rapamycin (Rap). Viable cells were annexin- and PI-negative. Results were obtained from 5 different samples and are presented as means ± SEMs. (B) For TUNEL staining, cells were cultured for 72 hours using the same conditions as described above. One additional independent experiment gave similar results.
