Bcl-2 protein expression of HL60, U937, and KG1 cells after 72-hours incubation with ATRA, 1,25(OH)2 D3, and GM-CSF. (A) HL60; (B) KG1; (C) U937. Results shown are mean of n = 3 (HL60 & KG1) or n = 7 (U937) experiments; error bars represent 1 SD above the mean. Statistical significance: * result statistically different from control; # result statistically different from ATRA/1,25(OH)2 D3 alone, eg, ATRA versus ATRA + GM-CSF; for P values see text.
