Immunohistochemistry analysis of Phospho-Pax2 (pSer393) showing nucleus and weak cytoplasmic staining of paraffin-embedded human kidney tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Anti- Phospho-Pax2 (pSer393) Polyclonal Antibody (369200) diluted in 3% BSA-PBS at a dilution of 1:50 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

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. Several pax genes have also been associated with developmental mutations including: pax-3, which is associated with Waardenburg syndrome, pax-6, which 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; thus, suggesting that WT1 can directly repress pax-2 transcription.
