Article Title: ABCG1 rs57137919G>A Polymorphism Is Functionally Associated with Varying Gene Expression and Apoptosis of Macrophages
doi: 10.1371/journal.pone.0097044
Figure Lengend Snippet: (a) Schematic diagram for constructing wild-type or mutant promoter at the ABCG1 rs57137919G>A polymorphism site. Two constructs were subcloned into pGL3-basic plasmid vectors with firefly luciferase reporter gene. pG, -367G (open bar); pA, -367A (grey bar). Luciferase activity assays for two ABCG1 promoter constructs in HEK293T cells (b), THP-1 cells (c), and HepG2 cells (d) are shown. Luciferase activities were measured with the dual-luciferase reporter assay system and normalized to Renilla luciferase activity 24 hours after transfection in the presence or absence of TO901317. The luciferase activity was a corrected relative value. Data are shown as mean ± SD of four independent experiments in triplicate. P <0.01 vs. pG in HEK293 cells, THP-1 cells, and HepG2 cells under both basal state and LXR agonist stimulation.
Article Snippet: The pGL3-basic empty vector was used as a negative control and the pGL3-control vector (Promega) was used as a positive control for the luciferase assay.
