DE microRNAs in meta-analysis results were associated with the enriched pathways with adjusted p-value < 0.05, including “MicroRNAs in cancer (hsa05206)”, “Pathways in cancer (hsa05200)”, “Proteoglycans in cancer (hsa05205)”, “PI3K-Akt signaling pathway (hsa04151)”, “Prostate cancer (hsa05215)” and “Signal Transduction (R-HSA-162582)”. This evidence concerns the gene AKT1 and prostate cancer.
