In our previous study, we have identified that the up‐regulation of a lncRNA signature consisting of nine lncRNAs (LINC00705, LINC00310, LINC00704, LINC00574, FAM74A3, UMODL1‐AS1, ARRDC1‐AS1, HAR1A and LINC00323) can predict recurrence of breast cancer.39 Therefore, we focused on LINC00310 in the present study. The gene discussed is LINC00705; the disease is breast cancer.
