CRBN modulates Wnt function in Drosophila.a A schematic showing a Drosophila melanogaster wing imaginal disc. A anterior; P posterior; D dorsal; V ventral. b Representative confocal images showing the level of the Wg/Wnt biomarker Senseless (Sens, magenta) after RNAi-mediated knockdown of (i–iii) yellow (y) control or (iv–vi) ohgata (ohgt/crbn), driven by a hh-Gal4 driver in the posterior compartment of third instar wing imaginal disks. The region in which hh-Gal4 drives expression is indicated by Engrailed (En) in green. DAPI staining (blue) is used to mark the wing disc. hh hedgehog, dcr dicer. Scale bar = 50 μm. c A quantification of wing disks with a defect in Sens levels is shown. Asterisks indicate statistical significance (Fisher’s exact test, ****p value < 0.0001).
