Furthermore, levels of STARD13 and its ceRNAs were markedly lower in primary breast tumors with lymph node metastasis than those in the metastasis-free primary tumors (Figures 3e-3h), while the levels of miR-9, miR-10b, and miR-125b were significantly increased in metastatic tumors (Figures 3b-3d), suggesting that STARD13 and its ceRNAs might play a metastasis-suppressive role in breast cancer. This evidence concerns the gene STARD13 and breast cancer.
