1 We previously found that a chloramphenicol acetyltransferase reporter gene driven by the collagenase TPA responsive element was expressed upon stimulation of T-cells by TPA and that this expression was enhanced when IL-1 was added as a costimulant; IL-1 alone had no effect on TPA responsive element-chloramphenicol acetyltransferase expression.

7 Although the levels of other fos-related mRNAs were also elevated, their maximal induction was delayed by approximately 5 h. IL-1 alone had little or no effect, but enhanced TPA induced transcription and steady-state levels of these mRNAs. Tetradecanoylphorbol Acetate interleukin 1 alpha Homo sapiens
8 These findings indicate that the synergistic effect of IL-1 and TPA on AP-1 mediated gene expression is due, in part, to the ability of IL-1 to enhance the expression of genes encoding specific AP-1 transcription factor components. Tetradecanoylphorbol Acetate interleukin 1 alpha Homo sapiens
