Twenty-four-hour pretreatment with forskolin does not induce desensitization of PGE2 cAMP responses. HFL-1 cells were treated with 1 μM forskolin for 24 h then washed, and acute responses to PGE2 were measured. cAMP levels were measured as a function of change in fluorescence normalized to the change in fluorescence of maximal response stimulated by 1 μM forskolin plus 200 μM IBMX using the cADDis assay. Data are mean ± SEM of n = 5. Not significant (p = 0.287) by 2-way ANOVA
