To determine the correlation of PGK1 expression with breast cancer patients survival, we performed the analysis and showed that increased expression of PGK1 mRNA is apparently correlated with reduced overall survival (OS) (p < 0.05), relapse free survival (RFS) (p < 0.05), and distant metastasis free survival (DMFS) in breast cancer (p < 0.05) (Figure 8A). Here, PGK1 is linked to breast carcinoma.
