As presented in Figure 8B–M, there were four lncRNA-miRNA pairs (LINC01128/miR-137, LINC01140/miR-429, SGMS1-AS1/miR-429 and LINC00667/miR-429) with negative expression correlation and eight lncRNA-MUC14 pairs (LINC01128/MUC14, CCDC18-AS1/MUC14, SH3BP5-AS1/MUC14, HOTAIRM1/MUC14, LINC01140/MUC14, SGMS1-AS1/MUC14, LINC01578/MUC14 and LINC00667/MUC14) with positive expression correlation in breast cancer. The gene discussed is CCDC18; the disease is breast cancer.
