Murine intrinsic cluster signatures according to tumor subtype. Standardized, average expression values for the dominant individual gene clusters from Figure 2i-v are shown according to the murine classes (left panels) and the human subtypes (right panels) using the human UNC308 human breast cancer dataset. (A) Murine claudin-low subtype defining gene set. (B) Murine luminal subtype gene set. (C) Murine basal-like subtype gene set. (D) Murine proliferation-associated gene set. (E) Murine lactation associated gene set.
