The result showed that only downregulation of hsa-miR-425-5p (the upstream miRNA of TACC3) (P=0.00019, HR=0.64 [0.51-0.81]), hsa-miR-146a-5p (P=0.0038, HR=0.72 [0.57-0.9]) and hsa-miR-150-5p (P=0.00049, HR=0.65 [0.51-0.83]) (the upstream miRNA of CXCR4) were correlated with poor overall survival (OS) of patients with ovarian cancer (Figure 6B-D, Supplementary Table S8). This evidence concerns the gene CXCR4 and ovarian cancer.
