Wild type and variant SIRT2 gene promoters were cloned into reporter gene vector pGL3 and transfected into HEK-293 cells. The transfected cells were collected and dual-luciferase activities were assayed. Empty vector pGL3-basic is used as a negative control. Transcriptional acitivity of the wild type SIRT2gene promoter was designed as 100%. Relative activities of SIRT2 gene promoters were calculated.
