PAX-2 is essential for the formation and differentiation of the metanephric kidney, where it regulates the expression of genes involved in nephrogenesis of the renal tubules, glomeruli, and collecting ducts. PAX-2 is also involved in the development of other structures in the urogenital system- including the ureter, bladder, and genital tract- and the neural tube in the central nervous system.\nAberrant expression of PAX-2 has been observed in renal cell carcinoma (RCC), ovarian cancer, prostate cancer, and bladder cancer. In some studies, high expression of PAX-2 has been associated with poor prognosis and disease progression in certain cancer types, while in others, its expression has been linked to better outcomes."}]}]}
