AQP3 and nonpapillary renal cell carcinoma: In the present study, the results from UALCAN revealed that the mRNA expression of AQP1, AQP2, AQP3, AQP4, AQP5, AQP6, AQP7, and AQP11 was remarkably lower in ccRCC samples than in corresponding normal renal tissues, and the expression of MIP, AQP8, AQP9, and AQP10 was higher in the former than in the latter (Fig. 2).
