Figure 3. Itraconazole combines with cyclopamine to inhibit GDC-0449-resistant SMO function.
(A) Relative 8×-GLI-luciferase expression in SHHN-stimulated Smo−/− MEFs expressing SMOWT or SMOD477G, treated with GDC-0449, itraconazole, or both. (B) Effect of KAAD-cyclopamine 100 nM, itraconazole 2 μM, or both on SHHN-stimulated 8×-GLI-luciferase expression in Smo−/− MEFs expressing SMOD477G. (C) Dose-response curves of KAAD-cyclopamine for SHHN activated signaling in Smo−/− MEFs expressing SMOD477G, in the presence or absence of itraconazole. Data represent mean of triplicates ± SD.
