CXCL10 is expressed in OC TAMs as well as in peritoneal macrophages from tumor-free patients (6, 7), while IL2 is not a transcribed gene in macrophages and hence is devoid of active marks but apparently harbors H3K4me3- and H3K4me1-modified nucleosomes within 2,000 bp of its TSS. This evidence concerns the gene IL2 and neoplasm.
