MAP3K5 and breast carcinoma: Similar to expression of pS134-GR and 14-3-3ζ (above), MAP3K5 mRNA levels are elevated in TNBC relative to other breast cancer subtypes represented in the METABRIC (Supplementary Fig. 5D), and MAP3K5 and GR mRNA expression levels are strongly correlated in TNBC patients (Fig. 6f) [16].
