Modulation of calcium pump expression by cAMP. HL-60 cells were treated with various concentrations of the cell-permeable cAMP analog CTP-cAMP for 4 days and SERCA expression was determined. (A and B) Concentration dependence of the modulation of SERCAPLIM and SERCA 2b expression by cAMP, respectively. Data represent the mean ± SEM of 3 experiments.
