Abstract

It has been proposed that ciliated cells that produce a leftward fluid flow mediate left-right patterning in many vertebrate embryos. The cilia on these cells combine features of primary sensory and motile cilia, but how this cilia subtype is specified is unknown. We address this issue by analyzing the Xenopus and zebrafish homologs of Foxj1, a forkhead transcription factor necessary for ciliogenesis in multiciliated cells of the mouse. We show that the cilia that underlie left-right patterning on the Xenopus gastrocoel roof plate (GRP) and zebrafish Kupffer's vesicle are severely shortened or fail to form in Foxj1 morphants. We also show that misexpressing Foxj1 is sufficient to induce ectopic GRP-like cilia formation in frog embryos. Microarray analysis indicates that Xenopus Foxj1 induces the formation of cilia by upregulating the expression of motile cilia genes. These results indicate that Foxj1 is a critical determinant in the specification of cilia used in left-right patterning.

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.
