Abstract

The murine Pax-2 gene contains a protein coding domain homologous to the Drosophila paired-box, first described in certain developmental control genes of the segmentation type. Polyclonal antibodies recognize two Pax-2 proteins that are encoded by differentially spliced mRNAs. The Pax-2 proteins can bind a DNA sequence known to interact with the paired domain of a Drosophila protein. By immunocytochemistry, expression of Pax-2 could be localized to the nuclei of condensing mesenchyme cells and their epithelial derivatives in the developing kidney. Expression is abruptly down-regulated as the tubular epithelium differentiates. High levels of Pax-2 expression could also be detected in the epithelial cells of human Wilms tumors. These data suggest that Pax-2 is a transcription factor active during the mesenchyme-to-epithelium transition in early kidney development and in Wilms tumor.

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.
