The SND1 protein level in TNBC tissues from 38 patients with lymph node metastasis (Met) and 20 patients without metastasis (non-Met) were evaluated by IHC, and 10 glioblastomas (GBM) high-expressing SND1 were used as positive control. This evidence concerns the gene SND1 and metastatic malignant neoplasm in the lymph nodes.
