AQP1 and lung carcinoma: In our study, the high expression of AQP1 in lung cancer was proved by RT-qPCR, contrasting with low miR-146a-5p levels in lung cancer tissues in previous work [25], which strengthened the reliability of our prediction results and implied that AQP1 might be a target of miR-146a-5p in diverse cancers, especially lung cancer.
