Figure 1.

Factor analysis in DCIS subgroup. Schematic representation of genes with a loading value <|0.6| characterizing the first (F1) and the second factor (F2). Solid color indicates a positive loading value whereas dashed color indicates a negative loading value. Color correspondence: light yellow, tight junction components; dark yellow, adherens junction components; light blue, polarity complexes components; dark blue, angiogenesis; orange, cell-fate decision; light green, luminal markers and hormone steroid; dark green, basal markers; pink, epithelial-mesenchymal transition, grey, GTPase family members.
