RARα, VDR, PU.1, C/EBPα, Gfi-1 and EGR1 nuclear transcription factor expression in wild-type HL60, R38+ HL60, R38− HL60, U937, K562 and NB4 cells at 48 h. Fold change of quantified Western blot data (from at least three biological repeat nuclear lysates) using ImageJ are shown with a representative blot. Note the scale on the y-axis may differ. Error bars represent standard error. T-test analysis is not possible for quantified blot data as luminescent signal may be in the linear or nonlinear range.
