Pax2 (Paired Box Gene 2, Paired Box Homeotic Gene 2, Paired Box Protein 2, Paired Box Protein Pax-2, Paired Box Protein Pax2, Pax-2) (APC)

The pax genes are a family of transcription factors that are active in specific tissues during early embryonic development. Pax family members possess a DNA-binding domain encoded by the paired box. Because paired domain containing genes encode transcription factors, they are capable of executing a genetic program. The paired box containing genes were first identified in Drosophila and were subsequently described in a variety of species including mouse, human, chicken, Xenopus and Zebrafish. Several pax genes have also been associated with developmental mutations including: pax-3, which is associated with Waardenburg syndrome, pax-6 is associated with Aniridia, and pax-2 which is associated with Wilms tumor. During embryogenesis, Pax-2 is expressed in the developing kidney. In particular, the pax-2 gene is expressed in condensing metanephric mesenchyme and in early epithelial structures derived from mesenchyme; however, pax-2 mRNA and protein levels are rapidly down regulated as the tubular epithelium matures. Although Pax-2 is down regulated during renal epithelium maturation, Pax-2 expression persists in the undifferentiated epithelium of Wilms’ tumors. Persistent expression of Pax-2 in Wilms’ tumors occurs frequently and correlates with the proliferation of poorly differentiated epithelial cells in these tumors. Interestingly, expression of the Wilms’ tumor suppresser protein WT1 coincides with down-regulation of the pax-2 gene, and the WT1 protein can directly repress pax-2 transcription. Therefore, pax-2 is thought to be a target gene for WT1.
