Ets2 suppresses inflammatory cytokines through MAPK/NF-κB signaling and directly binds to the IL-6 promoter in macrophages
Figure 6. Ets2 inhibits IL-6 transcription by binding to the IL-6 promoter. (A) ChIP analysis of the IL-6 promoter using an Ets2 antibody in mouse primary peritoneal macrophages treated with LPS for the indicated times. (B) Luciferase assay of IL-6 reporter gene expression in HEK293 cells transfected with 50 ng of a MyD88-expressing plasmid, 90 ng of an IL-6 luciferase reporter plasmid, and 10 ng of a pTK-Renilla-luciferase reporter plasmid, together with 0, 10, 25 or 50 ng of an Ets2-expressing plasmid. Luciferase activity was measured and normalized to Renilla luciferase activity. Data are shown as the mean ± s.d. Student’s t-test compared with the control group. **, P<0.01.
