Accordingly, EZH2 was expressed higher in basal-like/TNBC, HER2+ and luminal B BC compared to the luminal A BC and normal breast tissues (Figure 5A) and showed negative associations with OS, DFS, and DMFS of BC patients (Figures 5D–F), while the expressions of EGR1 and JUN were lower in these three types of BC (Figures 5B,C) and displayed positive associations with OS, DFS, and DMFS of BC patients (Figures 5G–K) except that the JUN expression had no statistically significant correlation with DMFS (Figure 5L). This evidence concerns the gene EZH2 and breast cancer.
