(A) Inhibition of NF-κB nuclear translocation induced apoptosis of human CD34⁺CD19⁻ human bone marrow cells. The deoxynucleotidyl TUNEL assay was performed on human CD34⁺CD19⁻ bone marrow cells (>98% pure) after (A) 16 or (B) 18 hours of incubation with various agents.19 The controls were incubated with buffer only (▤) or 50 μmol/L etoposide (▨). (A) NF-κB NLS peptide (▪); control mutant peptide (▩). (B) Flow cytogram comparison of apoptosis induced by 50 μg/mL NF-κB NLS peptide (black line) and control mutant peptide (gray line) shown in (A).
