Fig. 1. MAPK4 is highly expressed in a subset of basal-like BCa and TNBC.

Fig. 1

a MAPK4 mRNA expression across 817 BCa from The Cancer Genome Atlas (TCGA). Boxplot represents 5% (lower whisker), 25% (lower box), 50% (median), 75% (upper box), and 95% (upper whisker). P value by two-sided t test on log2-transformed expression values. n represents independent patients. b, c MAPK4 mRNA expression across 92 BCa PDX models, including 69 TNBC PDX models. MAPK4 is markedly expressed (at around the 50th percentile of all genes expressed) in these PDX tumors (b). IHC was used for evaluating ER, PR, HER2 expression status within these tumors.
