PAX8 is a member of the paired box (PAX) family of transcription factors, typically containing a paired box domain, an octapeptide, and a paired-type homeodomain. PAX proteins play critically important roles in development by regulating transcriptional networks responsible for embryonic patterning and organogenesis; a subset of PAX proteins also maintain functional importance during postnatal development. It is expressed during organogenesis of thyroid gland, kidney and Mullerian system. Research studies have implicated genetic mutations that result in aberrant expression of PAX genes in a number of cancer subtypes (1-3), with members of subgroups II and III identified as potential mediators of tumor progression. PAX8 antibody is expressed in a high percentage of ovarian serous carcinomas, endometrioids, thyroid follicular carcinomas, renal clear cell carcinomas, but only rarely in primary ovarian mucinous adenocarcinomas. PAX8 is a useful marker in distinguishing ovarian carcinoma from mammary carcinomas.
