    • Abstract:
      Follicular dendritic cell-secreted protein (FDC-SP) is a secreted protein expressed in follicular dendritic cells, periodontal ligament and junctional epithelium. To elucidate the transcriptional regulation of the human FDC-SP gene by tumor necrosis factor-α (TNF-α), we conducted real-time PCR, Western blotting, transient transfection analyses with chimeric constructs of the FDC-SP gene promoter linked to a luciferase reporter gene, gel mobility shift and chromatin immunoprecipitation assays using Ca9-22 gingival epithelial cells. TNF-α (10 ng/ml) induced FDC-SP mRNA and protein levels at 3 hr and reached maximum at 12 hr. In transient transfection assays, TNF-α (12 hr) increased the LUC activities of constructs between -116FDCSP and -948FDCSP including the human FDC-SP gene promoter. Transcriptional stimulations by TNF-α were partially inhibited in the -345FDCSP constructs that included 3-bp mutations in the YY1, GATA, CCAAT enhancer-binding protein 2 (C/EBP2) and C/EBP3. Transcriptional activities induced by TNF-α were inhibited by tyrosine kinase, MEK1/2 and phosphoinositide 3-kinase inhibitors. The results of ChIP assays showed that YY1, GATA and C/EBPβ transcription factors interacted with the YY1, GATA, C/EBP2 and C/EBP3 elements that were increased by TNF-α. These studies show that TNF-α stimulates human FDC-SP gene transcription by targeting YY1, GATA, C/EBP2 and C/EBP3 in the FDC-SP gene promoter.
