Abstract |
The T-box transcription factor Eomesodermin (Eomes) regulates the lineage-dependent expression of interferon γ (IFN-γ). We previously showed that Eomes promotes IFN-γ production and interacts with multiple conserved noncoding sequences (CNS) across the Ifng locus in mouse lymphoma BW5147 cells. In the present study, we investigated the transcriptional regulation of IFN-γ by the nuclear factor κB (NF-κB) subunit RelA and nuclear factor of activated T cells c2 (NFATc2, also known as NFAT1) in Eomes-transfected BW5147 cells. Eomes promoted the interaction of RelA and NFATc2 with the Ifng promoter and five CNS, including CNS-22 and CNS+30 upon stimulation with phorbol 12-myristate 13-acetate (PMA) and ionomycin (IM). The dual NF-κB and STAT3 inhibitor TPCA-1 moderately reduced the PMA- and IM-induced IFN-γ transcription in Eomes-transfected BW5147 cells. TPCA-1 interfered with RelA binding to the Ifng promoter, CNS-22 and CNS+30. Moreover, TPCA-1 reduced the interaction of Eomes or NFATc2 with the Ifng promoter and CNS+30. The present results indicate that Eomes promotes the interaction of RelA and NFATc2 with the Ifng promoter and multiple CNS across the Ifng locus in BW5147 cells.
