Figure 3. S. frutescens extract (SLE) suppressed the Gli/Hh signaling in Shh Light II and TRAMP-C2QGli cells.
A: Cyclopamine (Cyc) inhibited Gli-reporter activity in Shh Light II cells that were stimulated by conditioned medium (CM) or SAG. B: In the presence of CM, SLE significantly blocked Gli-reporter activity. C: In the presence of SAG, SLE significantly inhibited Gli-reporter activity. D: SLE but not cyclopamine inhibited the basal Gli-reporter activity in Shh Light II cells. E: SLE significantly inhibited the basal Gli-reporter activity in a dose-dependent manner in TRAMP-C2QGli cells. Each experiment was conducted at least thrice in triplicate. Error bars indicate standard deviation (SD). * P<0.05, ** P<0.01, *** P<0.001.
