In order to rule out that the higher expression of cFOS, MXD1, JUNB, cJUN, and DUSP1 in cytoplasmic NR4A1 expressing DLBCL is due the stringent conditions applied (below 20% and above 80%), we increased the number of lymphoma cases in our patient cohort (n = 34 consisting of 12 low and 22 high cytoplasmic NR4A1 expressing DLBCL - so a total of 51 DLBCL cases) by classifying all specimens as having lower or higher cytoplasmic NR4A1 expression than the median of 40% of lymphoma cells positive for NR4A1. This evidence concerns the gene JUNB and diffuse large B-cell lymphoma.
