Objective To investigate the role of stimulating protein 1 (Sp1) transcription factor in the transcriptional regulation of human endothelial-overexpressed lipopolysaccharide-associated factor 1 (EOLA1) gene. Methods Site-mutation of a putative Sp1 regulatory site locating at -734 to -666 of the core promoter of EOLA1 gene was used to analyze promoter activity. Electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation analysis (ChIP) were performed to confirm whether Sp1 bound to the site. Results Mutation of the Sp1 regulatory site resulted in a significant decline of EOLA1 promoter activity (P0.05). EMSA and ChIP showed that Sp1 bound to the site. Conclusion Basal transcription of EOLA1 gene is regulated by Sp1 transcription factor.
