AQP4 and ovarian cancer: Based on the above-mentioned comprehensive survival analysis platforms of KM plotter, our results showed that six members of AQPs (AQP3, AQP5, AQP6, AQP8, AQP10, and AQP11) mRNA expression were significantly correlated to favorable OS in ovarian cancer patients, whereas AQP0, AQP1, and AQP4 mRNA were associated with poor survival in ovarian cancer patients.
