Ascl1a/Dkk/β-catenin signaling pathway is necessary and glycogen synthase kinase-3β inhibition is sufficient for zebrafish retina regeneration
Open accessAbstract
Key to successful retina regeneration in zebrafish are Müller glia (MG) that respond to retinal injury by dedifferentiating into a cycling population of retinal progenitors. Although recent studies have identified several genes involved in retina regeneration, the signaling mechanisms underlying injury-dependent MG proliferation have remained elusive. Here we report that canonical Wnt signaling controls the proliferation of MG-derived retinal progenitors. We found that injury-dependent induction of Ascl1a suppressed expression of the Wnt signaling inhibitor, Dkk, and induced expression of the Wnt ligand, Wnt4a. Genetic and pharmacological inhibition of Wnt signaling suppressed injury-dependent proliferation of MG-derived progenitors. Remarkably, in the uninjured retina, glycogen synthase kinase-3β (GSK-3β) inhibition was sufficient to stimulate MG dedifferentiation and the formation of multipotent retinal progenitors that were capable of differentiating into all major retinal cell types. Importantly, Ascl1a expression was found to contribute to the multipotential character of these progenitors. Our data suggest that Wnt signaling and GSK-3β inhibition, in particular, are crucial for successful retina regeneration.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
