Combination with the histopathological staining results of NEDD9, it was found that the survival rate of patients with high NEDD9 expression (Fig. 1a) was significantly lower than that of patients with low NEDD9 expression (Fig. 1b), indicating that NEDD9 expression is associated with the metastasis and prognosis of BC patients (Fig. 1c, P < 0.001). The gene discussed is NEDD9; the disease is breast cancer.
