Abstract

Regeneration involves the integration of new and old tissues in the context of an adult life history. It is clear that the core conserved signaling pathways that orchestrate development also play central roles in regeneration and further study of conserved signaling pathway is required. Here we have studied the role of the conserved JNK signaling cascade during planarian regeneration. Abrogation of JNK signaling by RNAi or pharmacological inhibition blocks posterior regeneration and animals fail to express posterior markers. While early injury induced expression of polarity markers is unaffected, the later stem cell dependent phase of posterior Wnt expression is not established. This defect can be rescued by over-activation of the Hh or Wnt signaling pathway to promote posterior Wnt activity. Together our data suggest JNK signaling is required to establish stem cell dependent Wnt expression after posterior injury. Given that in vertebrates Jun has been previously shown to be required for the expression of Wnt and Wnt target genes, we propose that this interaction may be conserved and is an instructive part of planarian posterior regeneration.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In regenerating animals, pole expression of wnt1 is impaired in irradiated animals or after inhibition of several transcription factors Djislet, junli, and pitx.

    “By contrast, in regenerating animals, pole expression of wnt1 is impaired in irradiated animals or after inhibition of several transcription factors Djislet, junli, and pitx [10, 30–32, 40].”

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.
