The results suggested that metastasis associated RNAs, including AHRR, TTC34, CNTRL, ANKRD52, BCAR1, TMEM151B, PANX2, hsa-miR-105-5p, hsa-miR-4435, hsa-miR-5691, hsa-miR-92a-1-5p, and LINC01742 could serve as the prognostic biomarkers of breast cancer patients. The gene discussed is AHRR; the disease is breast cancer.
