OriGene flag tagged human klf4 expression vectors
Figure 1. PU.1 binds specifically to <t>KLF4</t> promoter during differentiation of myeloid progenitors to macrophages. A) PU/ER(T) cells were grown in presence of 95% Ethanol or 100 nM Tamoxifen for time periods as indicated. Cytosolic and nuclear protein fractions were prepared and translocation of PU.1 from cytosol to nucleus was detected by immunoblotting with anti PU.1 rabbit polyclonal antibodies. Purity of cytoplasmic and nuclear fractions was analyzed by immunoblotting with a-Tubulin and HDAC2 proteins. B) Nuclear extracts were prepared from differentiating bone marrow derived macrophages on day 1 and 7 and in vitro binding to biotin labeled 76 bp oligonucleotide probe representing 2118/2113 PU.1 binding element in the KLF4 promoter was determined by EMSA as described in methods. C) PU/ER(T) cells were treated with Ethanol or 100 nM Tamoxifen for 1, 4 or 24 h and nuclear extracts were prepared. An equal amount of nuclear protein extract from Ethanol and Tamoxifen treatment was analyzed for DNA binding activity using biotin labeled 76 bp oligonucleotide probe representing 2118/2113 PU.1 binding element in the KLF4 promoter. Specificity of PU.1-KLF4 DNA complex in experiment B & C was determined by the ability of the PU.1-KLF4 DNA complex to form supershift with anti PU.1 antibody. D) Specificity of PU.1-KLF4 DNA complex was determined by including 5, 15, 25 and 100 picomole of excess unlabelled KLF4 promoter oligo in the DNA binding reaction. E) In vivo binding of PU.1 to KLF4 promoter was determined by Chromatin-immuno precipitation in differentiating BMDM on day 1, 2 and 7 and in F) PU/ER(T) cells treated with Tamoxifen for 1 and 24 h. Error bars represent standard deviation and * is used where ever p value is #0.05 and ** is used when p#0.005. doi:10.1371/journal.pone.0093362.g001
