NFATc1 induces DNase I in target gene promoters in DLBCL. Plots of the DNase I digestion of control and FK-506-treated or NFATc1 shRNA-transfected DLBCL MS cells for promoters of c-myc, CD40L, BLyS, and Nf-M (a known DNase I–resistant locus). Standard curves were used to calculate the percentage of copies of the promoter's amplicon remaining in 50 ng of DNase I–treated genomic DNA.
