| abstractText | We have cloned and sequenced 1398bp of the rat HFE gene promoter region. The alignment of the rat promoter HFE sequence with the HFE promoter sequence from human and mouse detected several highly conserved sequences present at orthologous or heterologous positions in the three species. Subsequent analysis of the conserved promoter sequences identified the presence of 10 novel transcription elements present in the promoter regions of the human, mouse and rat HFE genes (GATA, NF-IL6, AP1, AP2, CREB, PEA3, gamma-IRE, GFI1, HNF-3beta, HFH2). Different gel retardation analyses performed with rat-liver nuclear extracts have confirmed the presence of factors binding to some of these transcription elements. This represents the first data concerning the identification of potential transcriptional elements of the HFE promoter in these three species. The expression pattern of the transcription factors corresponding to the novel elements identified in the HFE promoter is consistent with the potential role of the HFE promoter in the transcription regulation and function of the HFE gene. Knowledge of the identified conserved elements in the HFE promoter from human, mouse and rat provides the basis for subsequent in-vitro or in-vivo studies leading to identification of the detailed mechanisms involved in the regulation of the iron metabolism and the design of potential future alternative therapies. |
