Vitamin E TPGS 1000 Induces Apoptosis in the K562 Cell Line: Implications for Chronic Myeloid Leukemia

Figure 7

BAX/BCL-2 ratio had no significant changes in the presence of TPGS in K562 cells. K562 cells were incubated with increasing concentrations of TPGS (10–80 μM) at 37°C for 24 h. (a) Protein extracts were blotted with primary antibodies as listed. (b–d) Relative infrared fluorescence of (b) BCL-2, and (c) BAX antibodies were expressed as fold increase relative to that in untreated cells and normalized to actin. (d) BAX/BCL-2 ratio. Data are expressed as the ; , , and .
