Fig. 1. Temporal expression of JUNB and c-FOS mRNAs in MA-10 cells. Responses to hCG (40 ng/mL), db-cAMP (2 mM-plus-1 mM IBMX), TPA (20 ng/mL), and EGF (50 ng/mL)
are shown, and the data are presented as fold-increase over control (0 min). Each point represents the mean7range of integrated intensities from two independent
experiments.
