AML1 inhibits nuclear translocation and phosphorylation of p65. (A) Nuclear translocation assays of p65 in HEK293T cells transduced with AML1 or mock, 20 minutes after the addition of TNF-α. Scale bar represents 10 μm. Green indicates AML1; blue indicates TO-PRO3 (nucleus); and red indicates p65. (B) Intracellular FACS analysis of phospho-p65 (Ser 536) in HEK293T cells transduced with AML1 or mock. GFP-positive fractions were gated. Green line shows phosphorylated p65 protein 5 minutes after TNF-α stimulation. MFI indicates mean fluorescence intensity.
