dc.description.abstract | Hydrocortisone decreases major histocompatibility complex (MHC) class I gene expression in rat thyroid cells and counteracts increases induced by interferons. Using FRTL-5 cells transfected with class I promoter-reporter gene chimeras, we show that hydrocortisone action is transcriptional and mediated by an element located between 180 and 170 base pairs upstream of the start of transcription. Gel shift assays reveal that hydrocortisone causes the decrease of a specific protein-DNA complex; this same complex, referred to as Mod-1, is increased by interferon. Oligonucleotide competition assays reveal that the Mod-1 complex is associated with enhancer A of the class I gene, -180 to -170 base pairs (5'-GGGGAGTCCCC-3'), immediately upstream of the interferon response element. Antibodies to fra-2, a fos family member, and to the p50, but not the p65, subunit of NF-kappa B supershift the Mod-1 complex. We suggest that hydrocortisone decreases MHC class I gene expression by reducing the formation of Mod-1, which contains both p50 and fra-2; interferon reverses the hydrocortisone effect and increases Mod-1 formation. These observations are relevant to the molecular basis of hydrocortisone therapy in autoimmune thyroid disease and to the actions of interferon to exacerbate or induce autoimmune disease. | - |
