We found that the expression of RBM38 was positively correlated with the relapse free survival and overall survival of patients with breast cancer, and RBM38 can promote the competing endogenous RNA (ceRNA) network crosstalk among STARD13, CDH5, HOXD10 and HOXD1 (STARD13-correlated ceRNA network) and then inhibit the metastasis of breast cancer cells (9) (Figure 2). The gene discussed is RBM38; the disease is breast cancer.
