AP1 transcription is prevented by S. (A) Western blots for c-jun activation/phosphorylation were performed with lysates of either nonstimulated (nst), 1 h–stimulated (IgE/Ag), or 1 h S-pretreated cells before activation (IgE/Ag + S). c-jun and phospho-c-jun are indicated by arrows (right). (B) The transcriptional activation of an AP1-dependent reporter gene (3 x TRE) was measured in transient transfections. Corrected luciferase values are indicated on the y-axis, stimuli and input DNA on the x-axis. pGL2 represents the parental vector. Cells were activated for 3 h. Data represent mean ± SD of triplicate determinations.
