In the 179 tumor samples of breast cancer patients with follow‐up information, FAISL expression was positively associated with both tumor size (p = 0.0489), Ki67 index (p = 0.0029), lymph node (p < 0.0001) and distant metastasis (p = 0.0035) (Figure 7F; Table S4, Supporting Information). Here, VPS9D1-AS1 is linked to breast cancer.
