The reporter gene expression driven by PSA promoter in prostate cancer lines. A Construction of a luciferase reporter gene expression plasmid driven by the PSA promoter, with an additional constitutive promoter driving luciferase as an internal reference, which is not depicted in the figure. B Luciferase activity detected in prostate cancer cell lines and the normal prostate cell line. **P < 0.01 (Student’s t-test, n = 3 replicates)
