For ERα negative breast cancer cases, Table 3 shows that the immunohistochemical expression of TRPS1 has correlation with slug (P = 0.004), vimentin (P = 0.003), SMA (P = 0.031), and IMP3 (P = 0.005), which was further confirmed by Spearman correlation analysis (Figure 2). The gene discussed is SMN1; the disease is breast cancer.
