1 Analysis of the half-life of GnRH mRNA levels after transcriptional arrest with actinomycin-D (5 micrograms/ml) estimated the half-life of GnRH mRNA to be 22 h. TPA treatment did not alter the GnRH mRNA half-life directly, suggesting that the effects of TPA occur predominantly at the level of gene transcription. Tetradecanoylphorbol Acetate gonadotropin releasing hormone 1 Rattus norvegicus

4 Exposure of cells transiently transfected with various deletion constructs of the rat (r)GnRH promoter to TPA resulted in a decrease of 60% in luciferase reporter activity. Tetradecanoylphorbol Acetate gonadotropin releasing hormone 1 Rattus norvegicus
