Derepression of HyWnt3rep by Wnt activation. (A–C) EGFP reporter activities of transgenic Hydra carrying HyWnt3FL (A), Act-Wnt3prox (B), and HyWnt3prox (C) after 48 h for 24-h alsterpaullone treatment. Act-Wnt3prox showed ectopic EGFP expression in the body column in a spotted pattern similar to that resulting from HyWnt3FL but not HyWnt3prox. (Scale bar: 100 μm.) This figure is a composite of multiple panels.
