ABSTRACT
AIM:To assess the effect of seven cytokines on transcriptional regulation of HLA-B27 promoter, NF-?B and ISRE cis-element activity in HeLa cells.METHODS: HeLa-HLAB27 promoter stable cell line was constructed. The HeLa-B27 promoter stable cell line, HeLa-NF-?B stable cell line and HeLa cells transfected with pISRE-luc were cultured with different cytokines (IL-1?, IL-1?, TNF-?, IFN-?, IFN-?, IFN-? and TGF-?).RESULTS: TNF-?, IFN-?, IFN-? and IFN-? increased the B27 promoter activity at 96 h. The strongest inducer was IFN-?, the luciferase activity increased by 5.4 times. TNF-?, IL-1? and IL-1? also induced the NF-?B activity at 8 h (increased around 30 times). IFN-? and IFN-? increased the interferon-stimulated response element(ISRE) activity 10 times at 6 h.CONCLUSION: TNF-? and interferons increase the B27 promoter activity. IFN-? might play an important role in the pathogenesis of B27 related diseases.
