Pearson and Spearman correlation tests revealed significant overall correlation between JMJD6 and EZH2 in both normal and tumor samples irrespective of the tumor histopathology (DCIS, IDC1 to IDC3) or molecular subtype (TNBC versus non-TNBC) (Table 2). This evidence concerns the gene EZH2 and ductal breast carcinoma in situ.
