Figure 8. bcl-x Gene Promoter Activity by PG Treatment.
Primary cultured cardiomyocytes were transfected with luciferase constructs under the control of −905 bp human bcl-x promoter (A) or −3.2 kb mouse bcl-x promoter (B) using Fugene6 liposomes. At 48 hrs after transfection, cells were placed in 0.5% FBS for 24 hrs before treatment with 1 μM corticosterone (CT, A), 10 μM PG (A) or PG at indicated doses (B) for 24 hrs before harvesting for measurement of luciferases. A superscript letter indicates significant difference (P<0.05) from means labeled with a different letter as determined by ANOVA analysis.
