Validation of select microarray data by qRT-PCR. We also collected another 12 EEC and adjacent nontumorous endometrium samples and were used for qPCR detection. Hsa-miR-23a, hsa-miR-3941, hsa-miR-27a-3p and hsa-miR-3651 were the most significantly down-regulated miRNAs, whereas hsa-miR-920, hsa-miR-1204, hsa-miR-508-5p and hsa-miR-501-5p were the most significantly up-regulated miRNAs (n = 12 per group). The relative amount of each miRNA was normalized to the U6 snRNA. Significant differences between the EEC tissues and adjacent nontumorous endometrium samples are indicated by an asterisk (*P < 0.05)
