GDF15 and breast cancer: Results showed that PR status, pathological staging, and the expression of ADAMTS13 and NPPA correlated with the DFI; pathological staging and the expression of SEMA3B and GDF15 correlated with the DSS; PR status, pathological staging, and the expression of EDIL3 and MFAP4 correlated with the PFI; and pathological staging and the expression of SEMA3B, COL17A1, EDIL3, and GDF15 correlated with the OS of the breast cancer patients (Figure 2(e)).
