FoxA transcription factors are essential for the development of dorsal axial structures

Abstract

In vertebrates, embryonic structures present at the dorsal midline, prechordal plate, notochord, hypochord and floor plate share a common embryonic origin. In zebrafish, they derive from a pool of progenitors located within the embryonic shield at the onset of gastrulation. The molecular mechanisms responsible for the common development of these structures remain unknown. Based on their spatial and temporal expression, transcription factors of the Forkhead box A (FoxA) family appeared to be good candidates to play such a role. In agreement with this hypothesis, we found that simultaneous knockdown of FoxA2 and FoxA3 abolish the formation of all axial derivatives, while overexpression of these transcription factors strongly enlarges dorsal mesodermal territories. We establish that, in FoxA2-FoxA3 double morphants, precursors of axial tissues are correctly induced at early gastrula stage, but their dorsal midline identity is not maintained during development and we found that progenitors of these tissues are cell-autonomously re-specified to form muscle fibers as well as cells of the ventral neural tube. Our study provides the first example of a specific loss of all dorsal midline tissues and demonstrates that members of the FoxA family have redundant functions essential to maintain the axial identity of prechordal plate, notochord, floor plate and hypochord progenitors during gastrulation.

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

  • Some known notochord regulators, such as foxa3, were not identified as they are filtered out in the first steps of data processing owing to low expression.

    “However, it is important to note that some known notochord regulators, such as foxa3 (ref. 41), were not identified as they are filtered out in the first steps of data processing owing to low expression.”
  • A perturbation cannot be simulated if a TF-binding motif is unknown or TF expression is too sparse, as in the case of foxa3 in zebrafish.

    “For example, a perturbation cannot be simulated if a TF-binding motif is unknown or TF expression is too sparse, as we note in the case of foxa3 in zebrafish41.”

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.
