The results of K-M survival curves and log rank test suggested that the expression dysregulation of 7 mRNAs (AHRR, TTC34, CNTRL, ANKRD52, BCAR1, TMEM151B and PANX2), 4 miRNAs (hsa-miR-105-5p, hsa-miR-4435, hsa-miR-5691 and hsa-miR-92a-1-5p) and lncRNA LINC01742 in metastasis associated ceRNA were significantly related to the OS of breast cancer patients (Supplementary Tables S11–S13). The gene discussed is TTC34; the disease is breast carcinoma.
