Fig. 2From: Identification of a potent antagonist of smoothened in hedgehog signaling0025A inhibits the intravesicular aggregation of βarr2-GFP. a The U2OS cells stably overexpressing βarr2-GFP and Smo-633 were treated with different concentration of 0025A (10–12-10–6 M) for 24 h at 37 ℃. b Percentage of the number of βarr2-GFP aggregation was quantitated. GDC represented GDC-0449. Scale bar, 20 µmBack to article page
