A. Mouse SERCA2 promoter-luciferase construct show that CREB increases the transcriptional activity of the promoter and ERK1/2 decreases the transcription. All panels in this figure are representative experiments using H9c2 in triplicate, mean + SEM.
B. Mouse SERCA2 promoter-luciferase activity is decreased by cotransfection with a mutant active MEK, and this effect is reduced by MEK inhibitors. PD = PD98059, U = U0126.
C. PE significantly decreases transcription of the SERCA2 promoter, and MEK inhibition prevents the decrease.
D. Mouse SERCA2 promoter-luciferase contransfected with WT PKD, or a mutant active PKD does not have a significant change in transcription.
