Foxj1 transcription factors are master regulators of the motile ciliogenic program

Yu, Xianwen, Ng, Chee Peng, Habacher, Hermann, Roy, Sudipto·2008·Nature Genetics

Abstract

Motile cilia induce fluid movement through their rhythmic beating activity. In mammals, the transcription factor Foxj1 has been implicated in motile cilia formation. Here we show that a zebrafish Foxj1 homolog, foxj1a, is a target of Hedgehog signaling in the floor plate. Loss of Foxj1a compromises the assembly of motile cilia that decorate floor plate cells. Besides the floor plate, foxj1a is expressed in Kupffer's vesicle and pronephric ducts, where it also promotes ciliary differentiation. We show that Foxj1a activates a constellation of genes essential for motile cilia formation and function, and that its activity is sufficient for ectopic development of cilia that resemble motile cilia. We also document that a paralogous gene, foxj1b, is expressed in the otic vesicle and seems to regulate motile cilia formation in this tissue. Our findings identify a dedicated master regulatory role for Foxj1 in the transcriptional program that controls the production of motile cilia.

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.
