Figure 1. Differential enrichment of FASN, prolactin, and PRLR genes in breast cancer subtypes. FASN, prolactin, and PRLR mRNA expression levels in primary breast tumors from the METABRIC project classified into distinct subtypes using different classifiers. (PR+, n=903 versus PR-, n=797, Mann Whitney test; 3-genes signature, estrogen receptor (ER)-/HER2-, n=290, ER+/HER2- high proliferation, n=603, ER+/HER2+ low proliferation, n=619, HER2+, n=188, ANOVA with Dunn’s multiple comparison test; PAM50: basal, n=161, claudin-low, n=186, HER2 enriched, n=190, luminal A, n=631, luminal B, n= 412, ANOVA with Dunn’s multiple comparison test).
