Gene set enrichment analysis of signatures in the STAT3-high and STAT3-low subgroups of ABC DLBCL patients. (A) Expression of IL-6 target genes, IL-10 target genes, and NF-κB target genes in the STAT3-high and STAT3-low subgroups of patients with ABC DLBCL. (B) Average expression of IL-6 target genes, IL-10 target genes, and NF-κB target genes in the STAT3-high and STAT3-low subgroups of patients with ABC DLBCL. (C) Average expression of proliferation and glycolysis genes in the STAT3-high and STAT3-low subgroups of patients with ABC DLBCL.
