In addition, the Kaplan–Meier plot of ChaC2 (Affymetric ID: 235117_at), according to gene overexpression in breast cancer patients and their overall survival information, showed that the survival rate of patients with breast cancer with high ChaC2 expression levels was significantly lower than that with low ChaC2 expression levels (p < 0.001) (Figure 7A). This evidence concerns the gene CHAC2 and breast cancer.
