- OBJECTIVES: To establish a HEK293 cell line with a luciferase knock-in reporter controlled by the endogenous SREBP1 promoter for investigating transcriptional regulation of the SREBP1 gene. RESULTS: PCR confirmed the site-specific integration of a single copy of the exogenous luciferase gene into one allele of the genome and a 14 bp deletion of the targeted sequence in the other. Luciferase activity was directly correlated with the promoter activity of the endogenous SREBP1 gene in the HEK293-SREBP1-T2A-luciferase-KI cell line cell line. CONCLUSIONS: We successfully generated a novel luciferase knock-in reporter system, which will be very useful for studying transcriptional regulation of the SREBP1 gene and for screening drugs or chemical molecules that regulate SREBP1 gene expression.
