Expression patterns of key miRNAs in end-stage ADPKD kidneys. Homo sapiens

To investigate altered expression patterns of key miRNAs in end-stage ADPKD kidneys, a miRNA microarray analysis was performed using non-ADPKD and ADPKD kidney tissue samples. As a result, total 19 miRNAs were significantly changed in the ADPKD samples compared with non-ADPKD samples. Among these miRNAs, the expression level of the miR-192 family including miR-192 and miR-194 were significantly downregulated in ADPKD. Overall design: Renal cyst tissue samples were obtained from patients with ADPKD undergoing nephrectomy. As a control, non-ADPKD renal tissue samples were obtained from patients undergoing surgery for clear cell renal cell carcinoma, where malignant cell infiltration was excluded by histology.
