Expression of PAX8 or PAX2 in both nephrogenic adenoma and clear cell adenocarcinoma of the lower urinary tract may indicate a possible related tissue origin for these 2 lesions; both may be derived from proliferating renal tubular cells in the urinary tract PAX8 is a nephric-lineage transcription factor that is crucial for organogenesis of the thyroid gland, kidney, and Müllerian system. These proteins are required for cell growth and differentiation in embryonic tissues and can be expressed in adult tissues in specific cell-lineage neoplastic tissuesIn metastatic neoplasms, PAX 8 was expressed by 90 of (88%) renal cell carcinoma, nephrogenic adenoma, and ovarian carcinoma In metastatic neoplasms, PAX 8 was expressed by 90 of (88%) metastatic renal cell carcinoma,11,16 nephrogenic adenoma,17 and ovarian Keywords: Pax8, cell survival, tp53inp1, thyroid epithelial cells Expression of PAX8 in nephrogenic adenoma and clear cell adenocarcinoma of the lower PAX8 expression rates of metastatic carcinomas to the lung varied, Expression of PAX8 in nephrogenic adenoma and clear cell adenocarcinoma of the lowerWe suggest that PAX8 is an additional marker for identifying nephrogenic adenoma.
Some authors prefer the term ‘‘nephrogenic Nephrogenic adenoma is a benign growth typically found in the urinary bladder. It is thought to result from displacement and implantation of renal tubular cells, as this entity in kidney transplant recipients has been shown to be kidney donor derived. Clinical significance. Nephrogenic adenoma (NA) is a rare benign lesion of the urothelium, ﬁrst described by Davis in ,1 but better characterized by Friedman and Kuhlenbeck in They coined the term ‘‘nephrogenic adenoma’’ because of the morphologic similarity of NA to renal tubules. A mutation in the PAX8 gene could prevent or disrupt normal development This entity should not be confused with the similar-sounding metanephric adenoma PAX8 has been shown to interact with NK2 homeobox 1. The PAX8 gene is also associated congenital hypothyroidism due to thyroid dysgenesis because of its role in growth and development of the thyroid gland.Figure 1B Histologically, the tumor cells are small, monomorphic and cuboidal. such as papillary, clear cell RCC, nephrogenic adenoma, and urothelial neoplasms 1 sept Hirsch).

Importantly, all lung adenocarcinomas, breast and adrenal neoplasms, and the majority of gastrointestinal tumors were negative for PAX8. We suggest that PAX8 is an additional marker for identifying nephrogenic adenoma. Expression of PAX8 or PAX2 in both nephrogenic adenoma and clear cell adenocarcinoma of the lower urinary tract may indicate a possible related tissue origin for these 2 lesions; both may be derived from proliferating renal tubular cells in the urinary tract f renal transcription factor PAX2 as a diagnostic marker for nephrogenic adenoma. PAX2 was also detected in 2 of the 7 clear cell adenocarcinomas of the lower urinary tract. Both are cell lineage restricted transcription factors expressed in normal and neoplastic tissues of related origin, including renal tubular cells in both fetal and adult kidneys. Therefore, PAX8 is an excellent marker for confirming primary tumor site PAX8-PPARy gene rearrangements are seen in follicular variant thyroid carcinomas, noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), follicular adenomas and papillary thyroid carcinomas (rare) (Semin Diagn Pathol ;, J Clin Endocrinol Metab ;, Am J Surg Pathol ;)We suggest that PAX8 is an additional marker for identifying nephrogenic adenoma.

C terminal DNA binding domain is involved in transcriptional activation and repression activitiesPax8, one of the Pax family members, is expressed in developing kidney, neural tube, and developing and adult thyroid. 5 Specifically, Pax8 was shown to be required for both morphogenesis of the thyroid gland 6 and maintenance of the thyroid differentiated phenotype. Importantly, all lung adenocarcinomas, breast and adrenal neoplasms, and the majority of PAX8 is a highly sensitive marker for thyroid tumors, renal tumors, Müllerian tumors, and thymic tumors. (B) Nephrogenic adenoma, control group. 8, 9 These results show that PAX8 is a highly sensitive marker for thyroid, renal, Müllerian, and thymic tumors. 7 Together with another thyroid-specific transcription factor named TTF-1, Pax8 is involved in the regulation of thyroid-specific genes such as those encoding thyroglobulin (Tg), thyroperoxidase and sodium/iodide symporter. Nephrogenic adenoma, control group. Note negative staining with SV40 in epithelial cells.
