Fig 4. Expression of apoptosis associated proteins in HL-60 cells after VAE treatment.

Fig 4

A. HL-60 cells were treated with depicted VAE concentrations (~IC50) for 18 h. Cell lysates were incubated with a human apoptosis array detecting the relative expression of apoptosis-related proteins per sample. Each experiment was carried out in duplicate (n = 2). VAE treatment changes the expression of apoptosis associated proteins resulting in an increase of TRAIL-R1 and a decrease in several proteins including XIAP, survivin, claspin and p53. B. The down-regulation of survivin, XIAP, p53 and claspin was confirmed by Western blot. C. Activity of TRAIL-receptor-1 and -2 was measured by FITC-labelled monoclonal antibody and flow cytometry after treatment of HL-60 cells with distinct VAE concentrations for 18 h.
