In Vitro	Vismodegib (HhAntag691) is an ABCG2 inhibitor and can increase the effective intracellular concentration of mitoxantrone, another ABCG2 substrate, through blocking its export in HEK293 cells. Vismodegib (HhAntag691, 10 µM), resensitizes MDCKII/Pgp cells and MDCKII/MRP1 cells to colchicine treatment[2]. Vismodegib (25 μM or 50 μM) concentration dependently inhibits HCC and H1339 cells[3].
In Vivo	Vismodegib is a novel small molecule HPI, often used for clinical trials[1]. Vismodegib (0.3 to 75 mg/kg, p.o.) is highly efficacious in medulloblastoma allograft tumors. Vismodegib (> 46 mg/kg, p.o.) causes growth delay in patient-derived colorectal xenografts[4].
Cell Assay	When MTT assay is performed, an MTT reagent is added to each well to a final concentration of 150 µg/mL, and the cells are incubated for 1 to 2 hours at 37°C. The medium is then replaced with DMSO to dissolve the reaction product. Absorbance at 570 nm is quantified using a spectra MAX 340pc plate reader. For the XTT assay, 1 mg/mL XTT is mixed with 0.025 mM PMS, and 50 µL of the mixture is added to each well and incubated for 4 hours at 37°C. After the plates are mixed on a plate shaker, absorbance at 450 nm is measured. All results are normalized to a percentage of absorbance obtained in controls.
Animal Admin	Tumor-bearing mice are distributed into tumor volume-matched cohorts when the tumors reache between 200 and 350 mm3. The vismodegib-resistant medulloblastoma allograft, sg274, is developed by intermittent suboptimal dosing of a Ptch+/−, p53−/−medulloblastoma allograft. Vismodegib is formulated as a suspension in 0.5% methyl-cellulose, 0.2% tween-80 (MCT), and is administered orally. Tumor volumes are determined using digital calipers using the formula (L×W×W)/2. Tumor growth inhibition (%TGI) is calculated as the percentage of the area under the fitted curve (AUC) for the respective dose group per day in relation to the vehicle, such that %TGI=100×1-(AUCtreatment/day)/(AUCvehicle/day).
