Moreover, we further checked the prognostic values of our six genes in the public database TCGA portal (version 1.0) (http://tcgaportal.org/TCGA/Breast_TCGA_BRCA/process.php), and we found that ZDHHC9, LRP11, PCMT1, TMEM70 were associated with poor prognosis, while IRF2 and KCNJ11 were related with good prognosis of BC patients (Figure 7C). This evidence concerns the gene ZDHHC9 and breast cancer.
