Abstract
Promoter analysis is the most basics in the analysis of gene regulation. Luciferase gene is the most commonly used reporter gene in promoter analysis. Luciferase is an enzyme that is used when firefly and Renilla reniformis (sea pansy) emit light. The first experimental step in this reporter gene assay is to connect a particular DNA segment to a luciferase gene. The second step is to transfect the reporter construct into the cells. Thereafter, stable luciferase will be produced with the help of transcriptional machinery, mRNA transporters, and translational machinery in the cells. Luciferase assay measures the quantity of light that is emitted by luciferin-luciferase reaction. Consistent with the fact that CCN2 expression has been shown to be altered by a variety of stimuli, the CCN2 promoter region also haa been shown to be bound and regulated by multiple transcription factors such as Smad, MMP3, NF-κB, AP1, TCF/LEF, and Sox9.
