The effect of progesterone (1 μm) on the activity of various transcription factors. In this experiment SIGCs were incubated in serum-free medium for 6 h in the presence or absence of progesterone. The activity of these transcription factors was assessed using luciferase report assays provided by Signosis BioSingal Capture (Sunnyvale, CA). Values are expressed as a percentage change from serum-free control. Progesterone induced either a significant (p < 0.05) increase or decrease in activity.
