The scores of SRGN staining positively correlated with the scores of TGFβ2 staining in TNBC tissues (Figure 5g), and was significantly higher in TNBC tissues with lymph node metastasis (Nodal Positive) than in TNBC tissues without lymph node metastasis (Nodal Free) (Figure 5h). This evidence concerns the gene TGFB2 and metastatic malignant neoplasm in the lymph nodes.
